        This tutorial owes its very existence to the work by \emph{Luigi
        Cataldi}, who a few years ago produced a wonderful manual for
        {\PMX} in Italian. Luigi's manual features many examples which
        help greatly in understanding some of the arguably arcane {\PMX}
        notation.

        \medskip
_{manual!Cataldi's Italian {\PMX} manual} _{Cataldi, Luigi}
        Even though the Cataldi manual is, as Don Simons has aptly
        remarked, ``written in the language of music'', it nevertheless
        seemed useful to have access to it for non-Italian speakers, so
        Don asked around for help on a `retranslation'.

        \medskip
_{manual!Don Simons' manual for {\PMX}, Version 2.40} _{Simons, Don}
        In fact, that is what the present tutorial started out with:
        essentially a retranslation of the {\PMX} part of Luigis manual
        back into English, using, where that seemed feasible, Don's
        original {\PMX} manual. I had been thinking for some time of
        producing some examples (and an index) for the updated ({\PMX}
        2.40) version of that manual, and now, taking Luigis italian
        version as a basis, it seemed an easy thing to do.

        \medskip
        Of course, as such projects go: soon after the first version had
        appeared in 2002, it tended to get out of hand --- Don Simons
        actively produced one new beta version of {\PMX} after the
        other, and I simply could not keep up with his pace.

        \smallskip
        So alas: 5 long years went by before the first update of
        the tutorial -- reflecting all {\PMX} changes from Version 2.40
        to Version 2.514 , in one giant step! -- had become possible.

        But, incessantly, as the development of modern {\TeX} and
        {\LaTeX} has moved on in an accelerating pace, and so have
        {\MusiXTeX} and {\PMX}. This tutorial was also bound to
        follow suite. So now the current status of {\PMX}
        (\texttt{2.603}) and this tutorial are closely synchronized for
        the first time.

        \bigskip
        After thanking Luigi, in particular for his kind permission to
        use his version of the manual and its examples liberally, it
        behooves me to thank Don even more, not only for originating and
        continuously maintaining and improving {\PMX}; his suggestions
        and continuous assistance in my work on this tutorial throughout
        the years were invaluable, as was his conscientious reading and
        improving, from the first draft to the present version. Many
        friends (too numerous to mention all of them) kept me busy
        trying to keep up with their productive suggestions and
        clarifications on the
        \href{mailto:tex-music@tug.org}{{\TeX}-music users' list}
        during the past years.

\pagestyle{headings}

\section*{How to use this tutorial}
\addcontentsline{toc}{section}{How to use this tutorial}
_{tutorial}

The purpose and function of this tutorial is, actually, twofold: for the
novice with {\PMX}, it should be a readable guide to finding out what
{\PMX} does (and what it doesn't), how it is sensibly used, and what to
do when you run into difficulties. For the seasoned user, on the other
hand, it should serve as an extended {\PMX} manual,
\begin{enumerate}
   \item giving a reasonably accurate account of \emph{all} the
         available features in an order which should make it not too
         tedious to find an answer to whatever question one might have,
   \item indicating some of the more common uses of straight {\MusiXTeX}
         commands to do things not available in {\PMX} directly.
\end{enumerate}

\medskip
As a consequence of this twofold purpose, the two types of readers
should have two very different approaches:
\begin{description}
   \item[The novice] should, after reading Section~\ref{sec:TeXetc},
        turn right to Section~\ref{sec:concepts} and \ref{sec:notes}.
        After that you should get your fingers dirty as quickly as
        possible: keep your first own {\PMX} file \verb#my_opus.pmx# as
        simple as possible, and proudly produce your first print,
        following the instructions given in Section~\ref{sec:running}.
        From thereon follow your interests!
   \item[The seasoned user] will usually need the tutorial mainly to find
        out the exact usage of some commands he unforgiveably forgot
        about, retrieve some rarely used procedure, or find some clever
        gimmick that he never was aware of. Those people will first scan
        the whole tutorial quickly in a matter of minutes to see what's
        there and gloat about what's missing, and later on rely on the
        index -- or look into authoritative source, the
        \href{http://icking-music-archive.org/software/pmx/pmx260.pdf}{PMX
        manual} by Don Simons.
\end{description}

_{Quick Reference Table}
Of course, once you have gotten acquainted well enough with {\PMX}, all
you'll ever need is Don Simons' ``Quick Reference Table''\,%
\footnote{The Quick Reference Table is found in the software section of
          the \textbf{W}erner \textbf{I}cking \textbf{M}usic
          \textbf{A}rchive as
          \href{http://icking-music-archive.org/software/pmx/ref260.pdf}%
          {\texttt{ref260.pdf}}\,.
         }.
That summarizes the {\PMX} symbols with all their options and always
reflects the latest version. Errors found in the
Quick Reference Table should be reported to Don Simons directly, whereas
all complaints (outright errors, awkward formulations, missed
subtleties) should be sent solely to the author.

\bigskip
_{\PMX}
This tutorial refers to {\PMX} 2.603 , as of Dec 11, 2010. For details
on the differences with previous versions consult the ``list of
changes'' of {\PMX} in the software section of the WIMA
(``\textbf{W}erner \textbf{I}cking \textbf{M}usic \textbf{A}rchive'').

\section{ {\TeX}, {\MusiXTeX}, {\PMX}, {\MTX} } \label{sec:TeXetc}
_{\TeX} _{\MusiXTeX} _{\PMX} _{\MTX}


{\MusiXTeX} is undoubtedly one of the best programs for typesetting
musical scores: it produces ready-to-print output in PostScript and PDF
format, it is stable, is continually updated, and is in the public
domain and thus \emph{totally free}.

Nevertheless its use seems to be limited, with few exceptions, to
musicians coming from the world of science. {\MusiXTeX} does not `look
and feel' very intuitive, and it sometimes requires a familiarity with
terms that may seem elementary to software programmers but are tough
going for straight musicians. Furthermore, it is not WYSIWYG software
(\textbf{W}hat \textbf{Y}ou \textbf{S}ee \textbf{I}s \textbf{W}hat
\textbf{Y}ou \textbf{G}et). This means that while writing the music you
cannot immediately see the score as it will look when printed, because
you do not write the music graphically as you do by hand, but rather in
terms of a list of symbols that represent it. The system is not
interactive; rather, the process of producing a musical score consists
of several steps:           \label{p:intoduction}

\begin{enumerate}
  \item One writes the symbols in a special version of the {\TeX}
        language to a normal text file, using any text editor (such as
        \textbf{Emacs}, \textbf{Edit} or \textbf{Notepad}),
  \item this text file is compiled with {\TeX} to produce a
        \texttt{.dvi} output file. This \texttt{.dvi} file is machine
        readable and usually can be previewed on the screen,
  \item another program, e.g.~\texttt{dvips}, produces a PostScript
        file from the \texttt{.dvi} file, which again can be previewed
        on the screen or sent directly to a suitable printer.
\end{enumerate}

This symbolic and non-graphical nature of the program may discourage
many people, but it is in many ways an advantage. Being
fully aware of the symbolic character of the typesetting process while
working on your input lets you concentrate much better on the final
typographic output and keeps you from being distracted by the temptation
to play games with interactiveness.

{\MusiXTeX} is a collection of `macro's that permits producing musical
scores with the help of {\TeX}, the prestigious electronic typesetting
program written by Donald Knuth, which is mainly used in scientific
typesetting. In providing {\TeX}, Knuth not only put it in the public
domain (to be freely distributed), but stipulated that any application
that uses {\TeX} should also be in the public domain and freely
available, without charge or royalty.
_{Knuth, Donald E.}

_{{\TeX}}
Before {\TeX} can be used, it has to be properly installed on the
computer system at hand. Installing {\TeX} from scratch is not an easy
task; consult Chapter \ref{sec:installation} for the details.

Even after everything is properly installed and running, coding a
musical score in the {\MusiXTeX} language still remains a tedious
process. Fortunately, there exist two preprocessors, {\PMX} and {\MTX},
which dramatically simplify the input process; in fact they provide what
must be among the simplest possible systems of electronically encoding
musical scores.

_{\MusiXTeX} _{\PMX}  _{\MTX}
The first two bars of Mozarts \emph{piano sonata KV 545} illuminate the
difference in coding with either {\MusiXTeX}, {\PMX} or {\MTX}. The
codes given below for the  three systems of software all produce the
(identical) output, shown in figure~\ref{fig:mozart}:

\bigskip
Not only is the {\MusiXTeX} much longer, it undoubtedly is less
intuitive and more complicated than the other two.

\bigskip
In the present tutorial we shall describe in detail the usage of {\PMX}
and, in a very cursory way, that of {\MTX}.

_{\MusiXTeX}  _{\PMX} _{\MTX}
In the remaining part of this introduction, we treat questions of
installation of the entire system of {\MusiXTeX} and {\PMX}. The
whole installation procedure may seem a formidable task to non-experts.
But don't despair: your efforts will be rewarded by the best and
simplest system of musical typesetting available. And, to paraphrase a
famous {\TeX} error message: ``If in serious trouble, ask a wizard for
help''. Such wizards are literally at your fingertips; just sign up and
post your problem to the mailing list at ^{WIMA} (the \textbf{W}erner
\textbf{I}cking \textbf{M}usic \textbf{A}rchive):
\raisebox{-0.75ex}{%
                  \includegraphics[scale=0.6]{addresses/texmusiclist}
                  },
and someone is bound to be in the mood to answer.

\section{Installation}  \label{sec:installation}
_{Installation}

Recently, there has been a number of major improvements in the basic
{\MusiXTeX} software (increasing, e.g., the maximum number of
instruments allowed), and subsequently {\PMX} has also undergone major
improvements. As a consequence, {\PMX} now is really tuned
to \texttt{\MusiXTeX-T115}: with {\PMX}\texttt{(2.603)} you can make
full use of all the new features of {\MusiXTeX-T115}.

\medskip
The installation instructions given here refer explicitly to installing
{\MusiXTeX} and {\PMX} under Windows XP; they assume that you have
MiKTeX\,%
\footnote{MikTeX is a {\TeX} data-base system for Microsoft Windows
          users.
         }
installed (version 2.6 or higher).

For Unix, good instructions can be found in the software section of
WIMA: \\ \quad \href{http://icking-music-archive.org%
               /software/musixtex/musixtex-for-unix.html}%
               {\texttt{http://icking-music-archive.org%
               /software/musixtex/musixtex-for-unix.html}}~. \hspace*{\fill}


\pagebreak
\subsection*{Installation of \MusiXTeX\texttt{-T 115}
             and {\PMX} \texttt{2.603} }

\subsubsection*{\MusiXTeX}

A comprehensive -- and very readable -- installation instruction manual
for {\MusiXTeX}\texttt{-T 115} has recently been given by Andre van
Ryckeghem and Don Simons. To obtain it, download the
\href{http://icking-music-archive.org/software/pmxtricks/mxinsuse.pdf}%
     {PDF file} from the WIMA software page.

If you are not really an expert for installing high-level software under
the Windows XP system, you are probably well advised to simply follow
the instructions in the installation manual more or less by the letter,
using the default choices of folders.

But in any case, it is wise to first read this manual (it's only 6
pages) before starting to apply it.

\medskip
One point, pointed out explicitly in the {\MusiXTeX} installation
manual, is of particular importance: when updating your MiKTeX
installation, files that are not standard parts of the MiKTeX data base
tend to get lost or overwritten. In order to avoid this once and for
all, it is convenient have an extra folder for your `private' files in a
subdirectory of the MiKTeX ROOT directory (usually named
\verb#localmiktex#). Explicitly, if your MiKTeX directory is, e.g., \\
\verb#C:programs\miktex 2.7# \;, followed by
\verb#...\miktex\...#,\,
you should have an additional directory structure
\texttt{C:}{\bs}\texttt{programs}{\bs}\texttt{miktex 2.7}%
           {\bs}\texttt{localmiktex}%
           {\bs}\texttt{...}{\bs}\texttt{miktex}{\bs}\texttt{...} \\
and check that in the MiKTeX `settings -- root' window these folders
are listed as

\begin{center}
\begin{tabular}{|ll|}  \hline
path & Descriptions \\ & \\
\texttt{C:}{\bs}\texttt{programs}{\bs}\texttt{miktex 2.7} & Install \\
\texttt{C:}{\bs}\texttt{programs}{\bs}\texttt{miktex 2.7}%
                                 {\bs}\texttt{localmiktex} & \\  \hline
\end{tabular}
\end{center}
Then all files in the \texttt{localmiktex} folder and all its subfolders
will never be updated or purged by MiKTeX .

\medskip
Another way to installing {\MusiXTeX} -- designed specifically to
produce a TDS compliant structure
\footnote{`TDS' stands for a `TeX Directory Structure', which is a
          standard way of organizing all the TeX-related files on a
          computer system.
         }
of the data base in Windows XP -- has been described by Bob Tennent; all
the info is contained in
 \href{http://www.ctan.org/tex-archive/macros/musixtex/musixtex-texmf.zip}%
      {musixtex-texmf}, available at \texttt{CTAN}.

\medskip
At the same link you will also find a README with a terse, but clear
instruction how to proceed. There is just one important item to amend:
in the README it says: "unzip musixtex-texmf.zip at the root of a texmf
tree \dots" ; but, for the reason pointed out above, it is much safer to
unzip it in the \verb#localmiktex# folder of the MiKTeX structure.

\medskip
In all other respects, these 2 ways to installing {\MusiXTeX} will
produce identical results; so which of the two you want to employ is
just a matter of personal taste.

\pagebreak\noindent
To test the {\MusiXTeX} installation, download
\href{http://icking-music-archive.org/software/pmxtricks/sample.zip}{sample.zip}
from WIMA to some temporary folder and unzip it, obtaining the 3 files
\verb#sample.tex#~, \verb#sample.pmx#~, and \verb#pmxrun.bat#~. Then run \\
\hspace*{10ex}
\verb#etex sample.tex# \\
in a command line.

\Note{Make sure that when using basic {\TeX} you \emph{always} run
      \texttt{etex.exe} (`extended {\TeX}') and \emph{not}
      \texttt{tex.exe} !! Although {\MiKTeX} now uses extended {\TeX} by
      default, the 2 commands \texttt{tex.exe} and \texttt{etex.exe}
      still differ; and {\MusiXTeX} 115, as well as {\PMX} 2.6, will not
      run properly under ordinary \texttt{tex.exe} .
     }

\subsubsection*{\PMX}

\noindent
Compared to {\MusiXTeX}, installing {\PMX} 2.603 is a cinch. All you
need to do is
\begin{enumerate}
  \item downkoad
      \href{http://icking-music-archive.org/software/pmx/pmx2603.zip}%
           {pmx 2.603.zip} and unzip it,
  \item copy \verb#pmxab.exe# and \verb#scor2prt.exe# to
             \verb#...\localmixtex\miktex\bin# ,
  \item copy \verb#pmx.tex# to
             \verb#...\localmixtex\tex# ,
  \item run the {\MiKTeX} FNDB
        (`\texttt{F}ile \texttt{N}ame \texttt{D}ata \texttt{B}ase') .
\end{enumerate}

\medskip\noindent
To test the installation, run \\
          \hspace*{10ex} \texttt{runpmx sample.pmx} \\
in a command line.

\begin{description}
  \item[{\MusiXTeX}:] \emph{Daniel Taupin}
_{Taupin, Daniel}

        \href{http://icking-music-archive.org/software/indexmt6.html}%
             {\MusiXTeX} evolved from Music{\TeX} by
        \emph{Daniel Taupin}, a physicist in the Laboratoire de Phisique
        des Solides in Orsay, \emph{Ross Mitchell} (CSIRO Division of
        Atmospheric Research, Private Bag No.1, Mordialloc, Victoria
        3195, Australia) and \emph{Andreas Egler} (Ruhr--Uni--Bochum,
        Ursulastr. 32, D-44793 Bochum).

        {\MusiXTeX} had been maintained actively and conscientiously by
        Daniel Taupin until his untimely death in 2001 --- he died
        accidentally while climbing in the Alps. He is remembered with a
        \href{http://icking-music-archive.org/Memorial/Taupin%
        /Statements.html}{Memorial} on the web page of the Werner Icking
        Music Archive.

        After Taupins death, {\MusiXTeX} seemed quite stable and could
        thus, for all practical purposes, be considered `frozen' for a
        long time.

        However, nothing as lively as {\MusiXTeX} can really remain
        \marginpar{redo after release of T 115 !}
        literally frozen forever. A number of improvements have
        been continuously added by a group of {\MusiXTeX}perts, and,
        finally, Hiroaki Morimoto has kindly provided a new version
        of {\MusiXTeX} which corrects known bugs. Then a new and
        \emph{strongly enhanced version} of the {\MusiXTeX} manual was
        prepared by  a group led by Don Simons, which has now been
        officially released: {\MusiXTeX}-\texttt{T 114} . It is located
        at Werner Icking Music Archive (dubbed `WIMA') as

        \href{http://icking-music-archive.org/software/musixtex/%
             musixtex-t114.zip}{\texttt{musiXtex-t114.zip}}\,.

        \medskip
        Quite recently, Hiroaki Morimoto went even further in enhancing
        {\MusiXTeX}: his newest version, {\MusiXTeX} \texttt{T 115} ,
        now allows up to 24 instruments! While still a beta version as
        of this writing, it is likely to be released officially soon,
        and the present version of {\PMX}, version {\PMX} \texttt{2.603}
        -- and this tutorial -- is already based on {\MusiXTeX} \texttt{T
        115} .

\section{The Werner Icking Music Archive} \label{sec:Icking}
_{WIMA} _{Werner Icking Music Archive|see{WIMA}} _{Icking, Werner}

\textbf{Werner Icking} (June 25, 1943 -- February 8, 2001) was the
founder of the \emph{GMD Music Archive}, which contained downloadable
scores, various {\MusiXTeX} programs, a discussion list, and various
other musical resources in the public domain. His contributions to the
development and promulgation of this software were peerless. His
editions of music (in particular the edition of the complete `Urtext' of
J.S.\ Bach's pieces for violin and violoncello solo) are examples of
sophisticated technique, artistic sensibilty and philological
meticulousness. Everybody, whether expert programmer or complete novice,
would always find valid and unselfish advice from him, which invariably
ended with the motto ``\emph{hope this hilft}''. In time a small, but
regular group of faithfuls gathered around this site, from all over the
world, who never had met Werner in person, but nevertheless came to see
a friend in him, mainly through frequent email exchanges.

Werner died suddenly on February 8, 2001, while bicycling home from
work, as was his regular habit. That very day he had performed
maintenance work for the site and replied to messages on its discussion
list, of which he had been the main administrator. The community of
users of the archive decided not to disband, but to continue Werner's
work. Starting with the contents of the GMD Archive, a new site was
created, and dedicated to Werner's memory. It's official name is the
\emph{Werner Icking Music Archive}.

After some difficult times, it is now hosted by \quad
  \href{http://www.pait.dk}{\texttt{PALDAM IT}} ;
its URL is \\
\hspace*{\fill}  \href{http://icking-music-archive.org}%
       {\texttt{http://icking-music-archive.org}}\,. \hspace*{\fill} \\
Its chief administrator is Christian Mondrup,
_{Mondrup, Christian}
who more than any other provided reasoned guidance and continuity during
the difficult transition.

\bigskip
The archive houses four main categories of information:

          \label{p:Icking}
\begin{description}
  \item[Archive of sheet music]: Contains hundreds of royalty-free
       scores in PDF, many with their source code in {\MusiXTeX},
       {\PMX}, or {\MTX}. It is maintained by \emph{Christian Mondrup},
       who is also the main administrator of the Werner Icking Music
       Archive \\

_{Mondrup, Christian}
  \item[{\MusiXTeX} and related software]: Contains {\MusiXTeX} and
       related software, as well as user manuals and various add-ons. It
       is maintained by \emph{Don Simons} \\

_{Simons, Don}
  \item[{\TeX}-music list]:
_{{\TeX}-music users' list}
       This discussion list is invaluable to novices, advanced users and
       developers. Themes focus on technical problems of typesetting
       using {\MusiXTeX} and related software, but often drift into
       other musical subjects of historic or esthetic interest. It is
       not moderated, but you need to subscribe in order to participate.

                        and a little jargon, it may avoid some confusion

\footnotetext[2]{Quoted literally from the original introduction to
                 {\PMX} by its author, Don Simons. }
\renewcommand{\thefootnote}{\arabic{footnote}}

\paragraph{Typographical conventions:}
\begin{itemize}
   \item The \texttt{typewriter} typeface always indicates verbatim text
         \emph{exactly as you would input it to the computer}. This
         includes file names, {\MusiXTeX} tokens, and {\PMX} commands,
         e.g., \verb#barsant.pmx, \internote, c44# .
   \item \textbf{bold} typeface is used for two purposes: first, for
         program names (e.g.~\textbf{pmxab}), and second, when applied
         to a single letter within a normal word, to emphasize the
         mnemonics of a {\PMX} command (e.g.~\texttt{lr} signifies a
         ``\textbf{l}eft-\textbf{r}ight repeat'').
   \item When used in commands, \emph{italics}  represent input
         variables for which the user would substitute the appropriate
         actual value. To make this notation quite clear -- and distinct
         from the general use of italics for  emphasis -- , the variable
         will be surrounded by square brackets in such cases (e.g.\
         \texttt{L[}$n$\texttt{]P[}$m$\texttt{]M} ), but \emph{the
         brackets are not to be included with the verbatim text}.
\end{itemize}

\paragraph{Musical terms:} \text{} \\
The language of music is Italian, and so the radical solution of
terminological problems would be to use the Italian names throughout.
This would, however, defeat the whole purpose of this tutorial, so some
compromises need to be made, and some terms, which may be used
differently by different people, need to be clearly defined. So in this
tutorial
\begin{itemize}
   \item
_{staves}
         a \emph{staff} (plural \emph{staves}) means the set of 5
         horizontal lines in which music is usually notated, aptly
         called a \emph{pentagramma} in Italian\,%
         \footnote{Note that one-line staves, used for percussion
                   instruments (drums, triangles etc.), are presently
                   not implemented in {\PMX}.
                  }.
   \item a \emph{system} means a coherent set of staves to be played
         simultaneously.
   \item
_{voice}
         a \emph{voice} means a line of music that is a musical entity
         of its own, such as a melody. In polyphonic music, there is
         often more than one voice to a staff, e.g.~a 4-voice Bach
         choral is often written with the 2 top voices (soprano, alto)
         in one staff, the bottom ones (tenor, basso) in the other\,%
         \footnote{ {\PMX} allows 1 or 2 voices in one staff. }.
\end{itemize}

\paragraph{technical terms:} \text{} \\
\begin{itemize}
   \item a \emph{system} means a coherent set of staves to be played
         simultaneously.
   \item a \emph{block} is the series of PMX commands WITHIN ONE SYSTEM,
         formally >ended be a / (slash), which then must be the LAST
         CHARACTER on this input line\,%
         \footnote{This often precludes even \TeX\ comments (started
                   with a \%) on the same line, after the slash!

                   \PMX\ does not check for compliance with this rule,
                   but nevertheless it is good practice to adhere to it.
                   Otherwise you a liable to encounter weird errors
                   which may be difficult to trace.
                  }.
\end{itemize}


\section{Running {\PMX}} \label{sec:running}
_{\PMX!running {\PMX}}

As stated in the introduction (cf.~Section~\ref{sec:introduction}),
{\PMX} is a \emph{preprocessor} to {\MusiXTeX}. That means that with
{\PMX} the sequence of steps from the input to the printed paper is one
step longer:
\begin{enumerate} \setcounter{enumi}{-1}
  \item The user writes \emph{the symbols of the {\PMX} language} to a
        normal text file, using any text editor. The name of this file,
        ( say, \verb#my_opus.pmx#) \emph{must have the suffix}
        \texttt{pmx},
  \item the file \verb#my_opus.pmx# is run through the {\PMX} processor,
        \textbf{pmxab}.
_{\textbf{pmxab}}
        This produces the output file \verb#my_opus.tex#, \\[2ex]
        \fbox{\begin{minipage}{390pt}
              Note that in {\PMX} (like in Unix, but unlike Windows)
              spaces within a file name are \emph{not allowed}! If in
              the above example, the input file name were \texttt{my
              opus.pmx} instead of \texttt{my\underline{\;}opus.pmx}, an
              unpredictable error, with confusing error messages, would
              occur.
              \end{minipage}
             }

  \item the file \verb#my_opus.tex# is then processed with {\TeX} to
        produce a \texttt{.dvi} output file\,%
        \footnote{This step is a bit more complicated than it sounds
                  because it actually is a 3 pass system: it consists of
                  (i) running {\TeX}, (ii) running ^{\textbf{musixflx}},
                  and (iii) running {\TeX} again (details on the
                  rationale behind this are described in the {\MusiXTeX}
                  manual by Daniel Taupin).
_{Taupin, Daniel}
                 }.
        This \texttt{.dvi} file is machine readable and (usually) can be
        previewed on the screen,
  \item another program, e.g.~\texttt{dvips}, produces a PostScript file
        from the \texttt{.dvi} file, which again can be previewed on the
        screen, or sent directly to a suitable printer.
\end{enumerate}
Usually this whole process is automated to some degree by the use of a
so-called `script' or `batch' file, or with the help of some more
elaborate system of interconnecting software (most of these tuned to the
needs of the general {\TeX} community).
_{\PMX!running {\PMX}}

\medskip
There are too many variants of this kind of supporting software -- public
domain or commercial -- to discuss here, and personal preferences or
dispositions are too varied. If you are at a loss on what to use, send a
message to the {\TeX}-music list (cf.~p.\pageref{p:Icking}), and you
can trust that you get all the individual help you need.

\end{table}

\pagebreak
To illustrate the above process, however, an example for a typical
`batch' file, for a standard \textbf{Windows} system, is given in
Table~\ref{tab:runpmx}. This assumes that you have
installed
\begin{enumerate}
   \item a ^{\MiKTeX} system,
   \item a {\MusiXTeX} system,
   \item a \texttt{dvips} system,
\end{enumerate}
all installed in the standard way, and that you have produced the {\PMX}
input file \verb#my_opus.pmx#, using your favorite ASCII text editor.

You would then run
\begin{center}
   \verb#runpmx my_opus#
\end{center}
on a command line, and would see a Ghostview window opening, from which
you could print your opus (or do with it whatever you like).

\bigskip
You perhaps will want to write your own batch program\,%
\footnote{The \texttt{runpmx.bat} given in Table \ref{tab:runpmx} is
          identical with the \texttt{runpmx.bat} used in the installation
          guide (Section \ref{sec:installation}).

          When adapting this to your needs or writing your own batch
          file altogether, you should make sure that you use
          \texttt{etex.exe} in the 3 calls of {\TeX}.
          {\MusiXTeX}-\texttt{T115} and {\PMX} texttt{2.603} both
          require e{\TeX} (extended {\TeX})!
         }, to suit your personal requirements. Some further remarks on
how \textbf{pmxab}
_{\textbf{pmxab}} operates may prove helpful for that.

\medskip
First, whenever \textbf{pmxab}
_{\textbf{pmxab}}
terminates due to a syntax error, the exit code is set 1 (0 when there
are no errors). There are various ways of detecting this with batch
commands, and then acting accordingly.

\medskip
Second, \textbf{pmxab}
_{\textbf{pmxab}}
always writes a file \texttt{pmxaerr.dat}
_{\texttt{pmxaerr.dat}}
containing a single number: 0 if it exited normally, otherwise the line
number in the \texttt{.pmx} file where the syntax error was.  With
advanced batch programming techniques, this file can be opened and read,
and if there was an input error, a text editor can be opened and the
input point placed on the line with the error.

\bigskip
There have been several requests to allow {\PMX} to keep running even
after it detects an input error. This has not been done because in most
cases, any error messages after the first one would be meaningless, or
worse, uncorrected errors could cause crashes.  In any event, all the
output from \textbf{pmxab}
_{\textbf{pmxab}}
will be stored in the log file [\emph{filename}]\texttt{.pml}.

\subsection{Concatenating several files} \label{sec:concatfiles}
_{\PMX!concatenating several files}

Sometimes one wants to split the work on a score into several smaller
parts, not only when otherwise you would exceed some {\PMX} numerical
limit (cf.~Section~\ref{sec:limits}), but simply for practical reasons.
Logically, one should distinguish two separate cases:
\begin{enumerate}
  \item Within \emph{one and the same {\PMX} program}, there might be
        parts that recur identically in several regions of the full code,
        and one would not want to retype these over and over again (both
        for efficiency and for clarity reasons). In such cases, you
        would want to have a command similar to the \verb#\input# of
        {\TeX}, {\LaTeX} and many other programming languages.

        In {\PMX}, such an `\verb#\input#' command has the form
        \verb#AR[#\emph{file name}\verb#]#, where \emph{file name} is
        the name of the (ASCII) file you want to include, and
        \verb#AR[#\emph{file name}\verb#]# will insert this file
        at exactly that point in your {\PMX} program where the
        \verb#AR[#\emph{file name}\verb#]# is.\,%

        \begin{quote}
          A possible use for this procedure, i.e.\ using the \texttt{AR}
          command, could be to save typing when you want to include your
          favorite  option defaults that in fact you use in almost every
          piece of music you write with {\PMX}.

          But a simple ``cut \& paste'' is arguably a quite practical
          and more straightforward way of achieving this goal; moreover,
          if you want to be fancy about it, {\PMX} has a much more
          sophisticated tool to offer for that purpose\,%
          \footnote{In fact, there is yet another fancy tool,
                    i.e.\ including a `global' file with the specific
                    name \texttt{pmx.mod} , useful for special purposes.
                    For details on this, refer to the {\PMX} manual.
                   },
          viz.\ a macro (cf.\ Sec.~\ref{sec:macros}).
        \end{quote}

  \item Sometimes may have reason to make several
        completely independent {\PMX} files, producing their output
        separately. In the end, you would want to concatenate these
        pieces again. This can be easily done:

        \medskip
        Suppose you have coded the three movements of a piano sonata in
        three separate {\PMX} files: \verb#son1.pmx#, \verb#son2.pmx#
        and \verb#son3.pmx#. To create one single file from these,
        proceed as follows:
        \begin{enumerate}
          \item Process the three files \verb#.pmx# separately,
                obtaining the three files \verb#son1.tex#,
                \verb#son2.tex# and \verb#son3.tex# ,
          \item Create a {\TeX} file \texttt{son.tex} consisting of the
                following lines:
                 \begin{verbatim}
                  \input musixtex
                  \startmuflex
                  \let\startmuflex\empty
                  \let\endmuflexsav\endmuflex
                  \let\endmuflex\endinput
                  \input son1
                  \input son2
                  \input son3
                  \endmuflexsav
                  \bye
                 \end{verbatim}
          \item Process the file \verb#son.tex# , in the usual three
                passes ({\TeX}~$\Longrightarrow$ \texttt{musixflx}
                $\Longrightarrow$ {\TeX}). The resulting file
                \verb#son.dvi# then contains the full score of the
                entire sonata.
        \end{enumerate}
\end{enumerate}

\medskip
Alternatively, you can concatenate the files using {\LaTeX}, or more
specifically, the \textbf{mtxlatex} package. For details on this
see Section~\ref{sec:LaTeX}.

\section{Preliminary Concepts} \label{sec:concepts}

_{comments}
The {\PMX} code of a musical score consists of two parts, the
\emph{preamble} and the \emph{body}. Lines with a \% in column 1 are
comment lines (as in {\TeX}); they are disregarded by the program\,%
\footnote{Note, however, the additional conventions of
          the \textbf{scor2prt} program (see Chapter \ref{sec:scor2prt},
          pp.\ \pageref{p:scor2prt}).
         }.

\medskip
The \emph{preamble} contains the general specifications for a score,
some musical (e.g., number of instruments, meter, key signature), and
some typographical (e.g., number of pages, number of staves per page).

\medskip
The coding for the music itself is given in the \emph{body}, which in
turn usually has a \emph{header}. As an example, consider the first few
bars of Haydns \emph{quartet Op.76, no.2} . The music shown in
Fig.~\ref{fig:Haydn} is obtained from the {\PMX} source code given in
Table~\pageref{tab:Haydn}.

\section{Preamble} \label{sec:preamble}
_{preamble}

The \emph{preamble} consists of one or several lines of numbers,
followed by lines with typographical data relevant for the whole score.
The preamble ends with a line giving the name of the directory to which
_{\textbf{pmxab}}
\textbf{pmxab} is to write its output \texttt{.tex} file.

\subsection{Numerical input}  \label{sec:numinput}

The first line(s) of the preamble must contain 12 numerical
parameters, separated by one or more spaces (`white space'). In {\PMX},
as in {\TeX}, a line feed is equivalent to a white space, so the
following 3 forms of the beginning numerical input are all equivalent:

{\small
\begin{verbatim}
4	4	4	4	0	6 0	-1
1	1	16 .08
\end{verbatim}
}

\vspace*{-1.5ex}

\medskip\noindent
For the purpose of this tutorial, the 12 s are named\,%
\footnote{Their names are written in typewriter typeface here because in
          a way they \emph{are} input and, as some of the examples show,
          used as such, albeit only in comment lines. But these names
          themselves never occur in {\PMX} commands. (See, however,
          the footnote on p.\pageref{p:errormsg}).
         }.
\begin{center}
   \parbox{6cm}{\texttt{nstaves}, \texttt{ninstr},             \\[1ex]
                \texttt{mtrnuml}, \texttt{mtrdenl},  \\
                \texttt{mtrnump}, \texttt{mtrdenp},  \\[1ex]
                \texttt{npickup},                              \\

                \texttt{musicsize}, \texttt{fracindent}
               }
\end{center}

Their significance is as follows:

\begin{itemize}
\item
_{voice!several voices in one staff} _{\texttt{nstaves}}
      \texttt{nstaves}, an integer $\leq 24$, is the total number of
      staves per system. Each staff may contain either one or two voices
      (lines of music). The number of voices in a staff may change as
      the piece progresses, but the total number of voices at any one
      time cannot exceed 24. So if, e.g., there are 24 staves, there can
      only be one voice per staff.

_{\texttt{ninstr}}
      \texttt{ninstr}, an integer $\leq$
      \texttt{nstaves}, is the number of \emph{instruments}.  Each
      instrument has a unique name (cf.\ p.~\pageref{p:names}), and any
      instrument with more than one staff will have its staves joined
      with a curly bracket. Often there is only one staff per
      instrument, and \texttt{ninstr $=$ nstaves} in that case. There
      are two ways to assign more than one staff to one or more
      instruments:

      \begin{itemize}
      \item if only the first, i.e.\ the \emph{lowest}, instrument has
            more than one staff, such as in a score for piano and a
            one-staff solo instrument, simply make \texttt{ninstr $<$
            nstaves}, and any difference will show up in instrument 1,
            the bottom one in each system,
      \item When you need a more general assignment of staves to
            instruments, put a minus sign in front of \texttt{ninstr},
            and follow \texttt{ninstr} with the number of staves in each
            instrument in succession, in sequence from the bottom one up
            (the same order as the instrument names,
            cf.~p.\pageref{p:names}), separated by spaces. These numbers
            \emph{must} add up to \texttt{nstaves}: in a way, they are
            simply a partition of the numerical parameter
            \texttt{ninstr} .
      \end{itemize}

      \Example
      The preamble of the first example (Fig.~\ref{fig:diabolica})
      simply has \texttt{nstaves} $=3$ and \texttt{noinst}
      $=2$ : \begin{figure}[!htb]
         \begin{center}
            \raisebox{-0.75ex}{%
                              \includegraphics[scale=.82]{eps/diabolica.eps}
                              }
         \end{center}
         \caption{\textbf{C.C.\ Noack}, \emph{sonata diabolica, first
                  movement}, bars 12--17
                 }   \label{fig:diabolica}
      \end{figure}
      while the Stravinsky excerpt of Fig.~\ref{fig:agon} was obtained\,%
      \footnote{In the \PMX\ text with which Fig.~\ref{fig:agon} was
                produced, an additional \MusiXTeX\ command was used to
                gather the strings in a group in the usual way. This
                ``inline use'' of \TeX\ commands will be explained in
                detail in Section~\ref{sec:inlineTeX} .
               }
      with \texttt{nstaves} $=9$ and \texttt{noinst} replaced by
      \[   -7 \; 1 \; 1 \; 1 \; 1 \; 2 \; 2 \; 1 \;\;\; .  \]
      This tells \PMX\ that there are 7 instruments in all, with 1 staff
      each for the four strings, 2 each for the piano and the harp, and
      1 for the trombone. Note that these numbers -- 8 in all in this
      case -- count as \emph{one parameter}, i.e.\ the 12 numerical
      parameters of the preamble are made up of 19 numbers in this case:
      \begin{center}
         \begin{tabular}{l@{\quad:\quad}l}
9                          & (\texttt{nstaves})                    \\

0 \quad 2 \qquad 16 \qquad 0.14
& (\texttt{npages, nsystems, musicsize, fracindent})
         \end{tabular}
      \end{center}
\end{itemize}

\begin{itemize}
\item  _{meter}
      The following 4 numbers serve to define the meter of the piece.
      The first pair,
_{\texttt{mtrnuml}}
      \texttt{mtrnuml} and
_{\texttt{mtrdenl}}
      \texttt{mtrdenl}, are the \emph{logical} values which {\PMX} uses
      to calculate the length of a bar: \texttt{mtrnuml} is the logical
      numerator of the meter, i.e.\ the number of beats per measure,
      \texttt{mtrdenl} the denominator. \label{p:meterdefs}

_{meter!printed}
      The second pair,
_{\texttt{mtrnump}}
      \texttt{mtrnump} and
_{\texttt{mtrdenp}}
      \texttt{mtrdenp}, determines the appearance of
      the meter in the printed output, but has no effect on the internal
      timing analysis of {\PMX}:
      \begin{itemize}
      \item if \texttt{mtrnump} $>0$, then it and
            \texttt{mtrdenp} are printed literally as the
            numerator and denominator of the time signature. For
            example, \texttt{4 4 4 4} prints a standard
            4 quarters meter,
      \item if \texttt{mtrnump} $<0$, then the numerator actually
            used by \PMX\ will still be the positive value of
            \texttt{mtrnump}, but the entire time signature will be
            printed with a vertical slash through it,
      \item if \texttt{mtrnump}=0, then \texttt{mtrdenp}
            determines the printed meter as given in
            Table~\ref{tab:meter} and shown in Fig.~\ref{fig:meter}.
      \end{itemize}

\medskip
There are special rules for n/16 and n/1 time signatures (where the
latter "1" normally means a semibreve or whole note).  To get n/1 time,
\label{p:meterdefs0}
use \texttt{mtrdenl} $=0$ (zero) and \texttt{mtrdenp} $=1$\,%
\footnote{To remember this rule, recall that the printed denominator
          is taken literally, while the logical denominator represents
          the same time value that is denoted when entering ordinary
          notes (see section~\ref{sec:notes} below): there \texttt{0}
          stands for a whole note.
          The special rule for n/16 time is due to programming
          convenience.
         }.
For n/16 time, it is \texttt{mtrdenl} $=1$ and \texttt{mtrdenp}
$=16$. So the choice [\texttt{3 0 3 1}] for the 4 meter
parameters, for example, will give a 3/1 time, both in the {\PMX}
internal computations and in the printed output, while a 5/16 time is
indicated by [\texttt{5 1 5 16}].
\end{itemize}

examples of pickup bars.
_{pickup bar}

A pickup bar is the \emph{only} bar that can have a different number of
beats than the current value of \texttt{mtrnuml}. It must be followed
with the first regular bar \emph{in the same block}, i.e.\ the pickup
note(s) \emph{must not be followed} by a \texttt{|}, \texttt{/} or
\texttt{//}.
_{pickup bar}

We shall later describe a {\PMX} command to change the meter, and
explain how to use it for pickups to later sections or movements
(cf.~section~\ref{sec:meterchg}).

\begin{itemize}
\item If
_{\texttt{npages}}
      \texttt{npages} $>0$, it is the number of
      pages, and
_{\texttt{nsystems}}
      \texttt{nsystems} is then the
      total number of systems in the entire piece.  {\PMX} will spread
      the entire piece horizontally over this number of systems, and
      vertically over \texttt{npages} pages. For proper vertical spacing
      there should be from about 9 to 16 staves per page. If you specify
      too many staves for a given number of pages, one or more staves
      may spill over onto an extra page, but you will not see this until
      you preview the \texttt{.dvi} file. Possible remedies are to
      increase \texttt{npages}, decrease \texttt{nsystems}, or use the
      \texttt{Ae} command, to be described later (cf.~section
      \ref{sec:A}).

       \label{p:preamble}
\item If \texttt{npages} $=0$, \texttt{nsystems} is interpreted as the
      average number of bars per system. This is useful while building
      up a file a little at a time. {\PMX} will decide how many pages to
      use.
\item
_{staves!size} _{\texttt{musicsize}}
      \texttt{musicsize} is the height of a staff,
      in points. The only values allowed are: 16, 20, 24 or 29 .
\item
_{indenting first system}
      Finally,
_{\texttt{fracindent}}
      \texttt{fracindent} is the
      indentation of the first system from the left margin, expressed as
      a decimal fraction of the total line width.

      \smallskip
      Note that although logically \texttt{fracindent} could have any
      value between $0$ and $1$ , you should never use a value
      seriously over $.5$. It is not only  esthetically rather
      unpleasing, but may cause some unexpected havoc for {\MusiXTeX}.

\end{figure}

\bigskip
_{preamble!end of} _{working directory|see{directory}}
_{current directory|see{directory}} _{path name|see{directory}}
The preamble ends with a line that contains the path name of the
^{directory} to which you want the files (the \verb#.tex# file, in
particular) to be written when
_{\textbf{pmxab}}
\textbf{pmxab} processes your source text. Usually you will want that to
be the current directory: in UNIX this is denoted by \verb#./#~, in DOS
(most versions, including Windows) it is \verb#.\#\qquad. In any case,
the path -- and thus the whole preamble -- must terminate with \verb#/#
or \verb#\#~~.

\addcontentsline{toc}{section}{Body of the Input File}
_{body of Input File}

\bigskip
The rest of the {\PMX} input file is called the \emph{body}. It usually
begins with a number of global options, each on a line by itself,
called the \emph{header} (which can be empty).
\label{p:header}
_{header} _{\PMX!options!general}

\medskip
_{input block}  _{block|see{input block}}
Following the header, the input of the actual music begins.  The basic
unit is called a \emph{block}, each one consisting of from 1 to 15
complete bars. The input data for all bars in a block are entered for
each staff in turn, starting with the first (i.e.\ the \emph{lowest})
staff. The sequence of staves (and thus of the instruments) corresponds
to that in the preamble: the first is the bottom one of the system as it
appears in the final score, and the last is the top one. The input for
each staff ends with a \verb#/# (slash). The data for one staff need not
be contained on a single input line, but may spread over as many as
needed, with any number of blank lines and comment lines between them\,%
\footnote{Remember that in {\PMX}, as in {\TeX}, a line feed is
          equivalent to a space, and a sequence of many spaces is
          equivalent to one space.
         },
but after the end of one staff (i.e.\ after the slash), you \emph{must}
start the coding for the next staff on a new input line. A \emph{block}
ends with the slash of the last staff of the last instrument (the top
staff in the score).
_{input block!ending}

\medskip
Though you can put up to 15 bars in one block, many users of {\PMX} have
the habit of systematically writing one bar per block only. Sometimes,
however, for reasons of context, {\PMX} \emph{requires} a set of bars to
be in one and the same block (cf.~Section~\ref{sec:dynamics}). If you
do put more that one bar in a block, it is advisable (although not
required) to separate the bars with a \verb#|# (`vertical stroke'). The
main function of this is to provide visual separation in the input file,
and to help isolate input errors: if you put a \verb#|# anywhere except
at a bar end, the {\PMX} processor will stop and show you where it
detected the timing error. Otherwise (with a few minor
exceptions%
\footnote{For such an exception cf.\ the note on p.\pageref{p:repeats}.
         })
\verb#|# has no effect.
_{bar lines!in source}

It is also good practice to separate the blocks with comment lines that
state which bars are represented, as has been done in the input source
for Fig.~\ref{fig:Haydn} (p.\pageref{p:Haydn}).

_{pickup bar}
If there is a pickup bar (\verb#npickup# $>0$), it must be in a block
with the first full bar\,%
\footnote{If, for some reason, you do need to put the pickup in a
          separate block, set the initial logical meter to fit the
          pickup bar, then after the pickup bar do a blind meter change,
          as described in section~\ref{sec:meterchg}.
         }.

_{voice!several voices in one staff}
When there are 2 voices in a staff (e.g.~for an organ or other
polyphonic instrument, or in a choir or symphonic score), these are
entered consecutively in the coding for that staff, again starting with
the lower voice, and this voice is ended with a \verb#//# (`double
slash'). Here again, after the double slash, you \emph{must} start the
second voice on a separate input line. The coding for this staff is then
again concluded by a single slash.

\medskip
The two bars from \emph{Pellas et Melisande} by Debussy in
Fig.~\ref{fig:debussy} are an example. The bottom staff, that for the
trumpet, has only one voice, while the top staff (for the flutes) has 2,
thus giving a total of 3 voices.

\end{figure}

\medskip
_{voice!several voices in one staff}
The number of voices in a staff (1 or 2) is determined solely by whether
the first sequence of symbols for that staff ends with \verb#/# or
\verb#//#. Therefore the number of voices in any given staff can vary
from block to block, but not within a block. In other words, if you need
to change the number of voices in a staff, you must start a new block.

\medskip
_{\PMX!symbols}
Finally, a general characteristic of {\PMX} coding should be noted: all
data comprises sequences of \emph{symbols}, each one containing one or
more adjacent characters. These symbols -- including the
voice-terminating symbols \verb#/# and \verb#//# -- are \emph{always}
separated from each other by at least one space or line feed. Whenever
there are several characters strung together without spaces, they are
considered \emph{one single} {\PMX} symbol. This concept has already
been illustrated in prior examples. The construction of the symbols will
be explained in much more detail in the remainder of this chapter.

\section{Commands for the Individual Staves}
                 \label{sec:body}
_{\PMX!commands for individual staves}

\subsection{Notes} \label{sec:notes}
_{notes}

The most important input item is of course a single note. Its two
main features are its \emph{pitch} and its \emph{duration}.

\emph{The pitch} is primarily -- i.e.\ up to octaviation --indicated by
_{notes!pitch}
the note \emph{name} in \emph{lower case} letters: \texttt{c, d, e, f,
g, a, b} (do, re, mi, fa, sol, la, si). If the note is to have an
accidental, the note name is followed \emph{without a space} by
\texttt{s, f} or \texttt{n} for a \textbf{s}harp, \textbf{f}lat or
\textbf{n}atural; \texttt{ss}/\texttt{ff} for a double sharp/double
flat.

_{accidentals} _{notes!duration}

The \emph{basic duration}, i.e.\ the duration exclusive of a possible
dot, is indicated by the first unsigned digit following the note name,
again with no space: \texttt{9, 0, 2, 4, 8, 1, 3, 6} respectively for
double-whole (^{breve}), whole (^{semibreve}), half, quarter, eighth
(quaver), sixteenth (semiquaver), thirty-second, and sixty-fourth notes.
For a consecutive sequence of notes of equal duration, this needs to be
given explicitly only for the first note of the sequence. Subsequent,
consecutive notes with no explicit duration will `\emph{inherit}' their
basic durations from the most recent note with an explicit duration.
_{eighths} _{sixteenths}

A \emph{dotted/doubly dotted note} is indicated by the letter
\texttt{d}/\texttt{dd} just about anywhere\,%
\footnote{The only restriction on the position of \texttt{d} within the
          note symbol occurs if the dot is to be shifted
          (cf.~p.\pageref{p:dotshift}).
         }
in the note symbol, after the note name, of course.

It is important to note that, in contrast to the basic duration, a
dot is never inherited by a subsequent note.
_{notes!duration!not inherited for dotted note} _{dotted notes|see{notes}}

\medskip
The \emph{pitch} of a note is, of course, not determined by the note
name alone; the actual octave needs to be specified as well. For this,
there are three possibilities:
\begin{description}
   \item[explicit octaves:] \text{} \\
_{notes!pitch!explicit octave}
         A second unsigned digit\,%
         \footnote{In contrast to the letters for accidentals and dots
                   and other letters to be explained in
                   Section~\ref{sec:otherparams}, the 2 digits for
                   duration and pitch, if present,  must always be given
                   in this order. Specifically, if by omitting the
                   duration digit you use the inherited duration, you
                   can no longer specify the octave explicitly by an
                   unsigned digit.
                  }
         indicates the octave to which the note belongs. For reference,
         octave 4 runs from middle C to the B above. The lowest note on
         an 88-key piano is the A in octave~0, while its highest note is
         the C in octave~8 (cf.~also Fig.~\ref{fig:pitch}).

         \begin{figure}[!htb] \begin{center}
                                 \includegraphics[scale=.82]{eps/pitch.eps}
                              \end{center}
         \caption{{\PMX} notation for pitch
                         (second digit of note symbol)}
                  \label{fig:pitch}
         \end{figure}

   \item[inherited pitch:] \text{} \\
_{notes!pitch!inherited}
         For a note without any explicit octave or relative pitch
         indication, the octave is assigned by {\PMX} such that the note
         is placed in the octave that makes it nearest to the most
         recent note \emph{in the same voice}, i.e. the pitch is
         `inherited'. Thus for jumps of less than a fourth up or down,
         you only need to enter the note name to fully specify the
         pitch. This feature often lets you go for long stretches in a
         voice before needing to enter the octave. For jumps of a fifth
         or more, you need to specify the octave either explicitly as
         described above, or relatively as described below.

   \item[relative pitch:]
_{notes!pitch!relative}
         \text{} \label{p:relativepitch} \\
         A \texttt{+} or \texttt{-} (if not part of one of the signed
         numerical suboptions to be discussed later) indicates that a
         note is to be an octave higher or lower than it would otherwise
         be. Two consecutive \texttt{+}'s will raise the pitch two
         octaves, and so forth\,%
         \footnote{Two consecutive \texttt{+}'s can be abbreviated by
                   one \texttt{++} .
                  }.

    As an example of all this, compare Fig.~\ref{fig:reloctav} with the
    {\PMX} notations given under the staff\,%
    \footnote{The same result would be obtained with the full, absolute
              notation \texttt{c84 d84 e84 c85 b84 a84 g84 g83 | c26 g23
              | c04}; but this is obviously much more verbose.

_{notes!pitch!explicit octave}
              Explicit octave numbers can be combined with one or more
              \texttt{+} or \texttt{-}, although this is not
              recommended.
             }.

    \begin{figure}[!htb]
       \begin{center} \includegraphics[scale=.82]{eps/reloctav.eps}
       \end{center} \caption{Relative Octave Notations}
       \label{fig:reloctav}
    \end{figure}
\end{description}

_{notes!pitch!explicit octave}
The first note of each line of music in a block must contain at a
minimum the note name and a basic duration value. It is good
practice and can simplify editing if in addition an explicit octave is
set there.  However if it is not, {\PMX} will make some assumptions:  at
the start of the first input block the pitch will be set as if there
were a prior note of middle C. In later blocks {\PMX} will use the
obvious inheritance rules from the end of the prior block\,%
\footnote{However, if the number of voices in a staff has changed from
          the prior block, it is safest to reset the octave at the start
          of a new block. Duration is never inherited across block ends,
          and thus must be reset at the start of each input block.
_{notes!duration!not inherited across blocks} _{voice!several voices in one staff}
         }.

\subsection{Dotted Notes}  \label{sec:dotnotes}
_{notes!dotted note}

Inheritance of dotted notes is a little tricky. As was noted above, the
dot itself is never inherited; you always have to use a \texttt{d}  in
the note symbol, even if the actual duration and octave are the same as
the prior note.  But the \emph{basic} digit of duration need not be
reentered if it hasn't changed\,%
\footnote{There is an exception to this: if you decide to indicate the
          octave with an explicit digit (`absolute octave'), you must
          then enter the duration explicitly as well.
         }.
So for example, consecutive dotted half notes, each within a fourth of
the previous one, could be most cleanly entered as \texttt{cd24 ed gd
ed}, whereas \texttt{cd24 e} would represent a dotted half note followed
by a plain half note, since the basic digit of duration was for a half
note all along.

\subsection{Stems}  \label{sec:stems}
_{stems} _{stems!direction forced}  _{stems!length}

{\PMX} usually determines the correct stem length and direction
(\emph{up} or \emph{down}) of a note  automatically. This can, however,
be changed by the user, as needed:
\begin{itemize}
_{stems!options}
   \item the stem direction is forced to go \emph{up} with the letter
         \texttt{u} (`\textbf{u}p') anywhere after the note name, or
         \emph{down} with \texttt{l} (`\textbf{l}ower'),
   \item the stem length of non-beamed notes can be shortened by adding
         the option \texttt{S}, followed by a decimal number between .5
         and 4.0 , representing the shortening in units of
         \texttt{\bs{}internote}\,%
         \footnote{1 unit of \texttt{\bs{}internote} is roughly half the
                   distance between staff lines.
                  }.
         The shortening can be made ``sticky'', i.e.\ applied to all
         following notes by adding a colon (\texttt{:}) after the
         number. Stickiness is terminated by \texttt{S:} .

\end{itemize}

\subsection{Other Note Parameters}   \label{sec:otherparams}
_{\PMX!options} _{\PMX!options!notes}
Here are some more options that can be appended to a note symbol (as usual
without spaces):

\begin{description}
  \item[Inhibited beaming (\textbf{a})] \text{} \\
_{beaming!inhibited}
     Joining the note stems with beams is usually done automatically by
     {\PMX}\,%
     \footnote{For details of this cf.\ Section~\ref{sec:beams}.
              }.
     Sometimes, however, you may want to inhibit this explicitly for a
     single note; this is achieved by the letter \texttt{a} (for
     \texttt{a}lone).
  \item[Horizontal shift (\textbf{e,r})] \text{} \\
_{notes!horizontal shift}
     Sometimes you want to shift the horizontal position of a note, for
     example to avoid overlap with a note in another voice of the same
     staff.  The letters \texttt{e} and \texttt{r} do that: \texttt{e}
     shifts the note to the l\texttt{e}ft by its own width (a `notehead
     width'), while \texttt{r} shifts it to the \texttt{r}ight. An
     example of this can be seen in Fig.~\ref{fig:debussy}.
  \item[Shift of accidentals (\texttt{<} / \texttt{>})]
     \text{} \label{p:accidentals} \\
_{accidentals!position shift}
     Accidentals can be shifted too.  One way is to enter \texttt{+} or
     \texttt{-} immediately after the accidental character, then an
     \emph{integer} for the vertical shift in units of
     \texttt{\bs{}internote}, then another \texttt{+} or \texttt{-} ,
     followed by the horizontal shift, given as a decimal fraction of a
     notehead width. If you use this method, you \emph{must enter both
     numbers}. Alternatively -- if you need only an horizontal shift --,
     you can simply use \texttt{<} or \texttt{>}, followed by the shift,
     in notehead widths. When shifting a sharp to avoid another sharp, a
     left shift of $0.85$ is usually best. When shifting a flat to avoid
     a flat above it, a left shift of $0.3$ is suggested.
     \label{shifts}
  \item[Shift of the dot in dotted notes] \text{} \label{p:dotshift} \\
     The dot in dotted notes can be shifted analogously to the first
     method for accidentals, using signed numbers, except that the first
     (vertical) shift may be a decimal fraction.
  \item[Shorthand for dotted notes]
_{dotted notes!shorthand} _{shorthand!for dotted notes}
     \text{} \\ There are two special shorthand notations for dotted
     rhythms.  For normal dotted rhythms ($3:1$ ratio), if you include a
     period (\texttt{.}) in the note symbol, {\PMX} will
     \begin{itemize}
        \item assign a dot to the note just entered,
        \item terminate that note,
        \item prepare to receive the next note name \emph{without any
              space}, and
        \item automatically assign a time value to the second note equal
              to one-third of the first one.
     \end{itemize}
     No time value may be entered for the second note, but octave and
     accidental parameters may. Ornaments and slurs
     (cf.~Sections~\ref{sec:ornaments} and \ref{sec:psslurs}) following
     this symbol will apply to the second member. If you need to follow
     the main note with some modifying command, you can still use the
     shorthand (\texttt{.}) after that command and a space. The main
     advantage of this shorthand comes if you want to follow one dotted
     pair with another of the same rhythm; then you needn't enter any
     explicit duration value for \emph{either} member of the second
     pair. This is because after using the shorthand, the basic
     inherited duration value is set to that of the \emph{first} note in
     the pair; remember that the basic duration does not include the
     dot!

     For paired notes with 2:1 rhythmic ratios, the symbol \texttt{,}
     (comma) behaves similarly to the \texttt{.} (period) for 3:1
     rhythms as just described.

     \Note{If you use this shorthand for dotted pairs, either embedded
           in a single symbol or to start a separate symbol for the
           second member, then you \emph{cannot shift the dot position}.
           If you do need to shift the dot, you should not use the
           shorthand notation.

\subsection{Rests} \label{sec:rests}
_{rest} _{pause|see{rest}}

Rests are denoted by the letter \texttt{r} in place of a note name.
Rests have duration digits just like notes, but obviously no second
digit for giving an octave. As inheritance goes, an \texttt{r} behaves
just like a note: it can inherit its duration from the prior note or
rest, and notes as well as rests can inherit their duration from prior
rests.

\medskip
Any rest or sequence of rests that occupies a full bar will by default
be horizontally centered in the bar.

\medskip
There are a few special notations for rests:
\begin{itemize}
   \item \texttt{rp} (`\textbf{r}est \textbf{p}ause') denotes a full-bar
         rest (whole rest), regardless of what the meter signature for
         the bar may be,
   \item \texttt{rpo} (`\textbf{r}est \textbf{p}ause
         \textbf{o}ff-center'). The option \textbf{o} suppresses the
         centering of a pause,
   \item
_{rest!blank rest}
         \texttt{b} (`\textbf{b}lank') denotes a blank rest, i.e. one
         that \emph{does not appear in print}. Logically, it has a
         duration that is determined, as usual, either by an explicit
         duration specifier or by inheritance. Blank rests are most
         commonly used when there are two voices in a staff,
         and one drops out for some part of the current input bar\,%
         \footnote{Another interesting application is when you have two
                   homophonic voices in one staff and, for simplicity's
                   sake you want to write only one rest for both voices
                   (cf.~the last 2 bars in Fig.~\ref{fig:rests}) .
                  },
   \item
_{rest!multibar rest} _{\textbf{scor2prt}!multibar rest}
         \texttt{rm} (`rest \texttt{m}ulti-bar') followed -- without
         space! -- by an integer $n$ generates the multi-bar rest symbol
         with the number $n$ above it, signifying a rest for $n$ full
         bars\,%
         \footnote{This is used in particular when the parts for
                   individual instruments are generated from a full
                   score, as is done automatically by \textbf{scor2prt};
                   cf.\ Section~\ref{sec:scor2prt}).
                  }.
\end{itemize}
\noindent
\hspace*{2em}\fbox{\begin{minipage}{390pt}
     Note that that there can be \emph{only one instance} of a multibar
     rest in a given input block!
                   \end{minipage}
                  }

\medskip\noindent
The default vertical position of a rest depends on whether there are one
or two voices in the staff. For one voice it is just the {\MusiXTeX}
default: approximately centered on the middle line. On the other hand,
in the lower voice in a two-voice staff, the rest is lowered
by \verb#4\internote#, while in the upper line it is raised
by \verb#2\internote#. The default can be manually overridden by appending
\verb#+# or \verb#-# and an integer for the offset (in
\verb#\internotes#) from the \emph{middle} line of the staff. Note that
this means that, if in the case of 2 voices in a staff you want to have
the rest centered on the middle line, you need to code it as \verb#r+0#
--- see the last bar in Fig.~\ref{fig:rests}~.

Some samples of rests are given in Fig.~\ref{fig:rests}.

\subsection{Xtuplets} \label{sec:xtuplets}
_{xtuplet}

{\PMX} insists very strictly on checking that the sum of durations of
all notes or rests in a bar add up to the total required by the bar's
meter. Thus, it cannot deal easily with modern extensively\,%
^{polyrhythmic scores}, percussion in particular \label{p:polyrhythms}
\footnote{But such problems occur occasionally even in classical music.
          Thus, a real challenge to any {\PMX} expert is to code the
          (in)famous third movement of Mozart's Oboe Quartet KV 370,
          where suddenly the oboe changes to an alla breve (4/4), while
          the strings continue on in a 6/8 meter!
         }.
The only polyrhythmic feature built into {\PMX} are the traditional
xtuplets: doublets, triplets etc.\ , together with their usual notation.

\medskip
Xtuplets (duplets, triplets, etc.) can have from 2 to 24 notes or
rests\,%
\footnote{The default maximum of $24$ can be changed.
          Cf.~\ref{sec:limits} .
         }.
By default all notes in an xtuplet have the same duration; but some can
be dotted or have twice the basic duration
(cf.\ p.~\pageref{p:xtupletdoubling}). The notation is as follows:
\begin{enumerate}
  \item The symbol for the first note of an xtuplet begins exactly like
        a note symbol, with the name of the first note in the xtuplet,
        or an \texttt{r} if the xtuplet starts with a \textbf{r}est --,
        followed, as the case may be, by an accidental, a \texttt{d} or
        \texttt{dd}, a \texttt{+},\texttt{-} or explicit octave, and an
        optional duration digit. However, this duration, whether given
        explicitly or inherited from a previous note or augmented by a
        dot, is not the duration of the first note, but represents the
        \emph{total} duration of the \emph{whole xtuplet}.

  \item If the xtuplet is to be \emph{unbeamed}, add an
        `\texttt{a}' (`alone') right after the first note.
  \item Next -- with no space, as usual -- comes \texttt{x} (for
        `\textbf{x}tuplet'), followed by a one- or two-digit integer,
        for the number of notes in the xtuplet . If the first note is to
        be dotted, add the usual \texttt{d}, if it is to have twice the
        basic duration, add a \texttt{D} or \texttt{F} (cf.\
        page~\pageref{p:xtupletdoubling} for more detail on this). The
        only options allowed after this begin with the letter \texttt{n}
        and control the printed appearance of the xtuplet:
        \begin{itemize}
          \item If \texttt{n} is omitted, the xtuplet is printed in the
                standard way, i.e.\ with the xtuplet $3$ printed over (or
                under, as the stemming may dictate) for, say, a triplet.
                Note also that by default {\PMX} prints a bracket only
                if the xtuplet notes are unbeamed; otherwise just the
                xtuplet number is printed.
          \item If \texttt{n} is followed by an \emph{unsigned} integer,
                this integer is taken as the number to be printed
                instead of the natural (default) one.
          \item If \texttt{n} is followed by the letter \texttt{f}
                (\textbf{f}lip), the xtuplet number is \textbf{f}lippped
                vertically from its default position. \item The position
                of the xtuplet number can be adjusted in the usual way
                with one or two \emph{signed decimal numbers} following
                \texttt{n}: the first is a vertical shift in units of
                \texttt{\bs{}internote}, the (optional) second a
                horizontal shift, in notehead widths.
          \item If \texttt{n} is given, but followed by a space, thus
                ending the first-note symbol, \emph{no number} at all
                will be printed.
          \item
_{xtuplet!tweaking the bracket slope}
                For a \emph{non-beamed xtuplet only} a suboption
                \texttt{s} can be added to the \texttt{n} option by
                which the slope of the bracket can be adjusted ; i.e.\
                you can use \texttt{ns}[\emph{n}], where \emph{n} is
                an \emph{signed} integer (except zero): a positive
                integer will lift the end of the bracket upwards, while
                a negative one will move it downwards.

                Note that this suboption will operate in a more
                elegant way for Sicherman-type xtuplets\,%
_{Sicherman-type xtuplets!see xtuplets}
_{xtuplets!ajusting slope with Sicherman xtuplets}
                \footnote{For Sichermann xtuplets cf.\ the next page.
                         }
                only: when the Sichermann option \textbf{AT} is
                \emph{not in effect}, the bracket number (the 3 in a
                triplet, e.g.) will \emph{not} follow the slope
                adjustment and might have to be tweaked separately.
        \end{itemize}
  \item The second through last notes of the xtuplet are then each
        given by a separate note symbol, containing the meaningful
        subset of the parameters permitted for notes or rests:
        \begin{enumerate}
           \item the note name as the first character. This is the only
                 required character. It can be an \texttt{r} (for a
_{xtuplet!rest in xtuplet}  _{rest!in xtuplet}
                 rest), except that the \emph{last note of an xtuplet
                 cannot be a rest}\,%
                 \footnote{Cf.\ however, Sec.\
                           \ref{sec:Xtuplets ending with a rest}
                          },
           \item an accidental,
           \item an octave change (\texttt{+} or \texttt{-}). The octave
                 may also given explicitly; this is the only digit
                 allowed,
           \item a \texttt{d} (\textbf{d}ot). The next note after the
                 dotted one is automatically shortened to half the
                 normal value,
           \item
_{xtuplet!doubled note}
                 \label{p:xtupletdoubling}
                 the character \texttt{D} in the note symbol for any
                 note in an xtuplet doubles the duration of this note.
                 As this accounts for two notes of the xtuplet, it will
                 decrease the expected number of notes in the xtuplet by
                 one. If used for the first note of an xtuplet,
                 \texttt{D} goes \emph{before} an optional \texttt{n}
                 parameter, \item
_{xtuplet!doubled note in Bach notation}
                 the character \texttt{F} is the same as \texttt{D},
                 except that in the printed output the doubled note will
                 appear dotted (a notation Bach sometimes used). As with
                 \texttt{D}, an \texttt{F} for the first note goes
                 \emph{before} an optional \texttt{n} .
           \item grace notes are allowed in xtuplets.
_{grace notes!in xtuplet}
                 \end{enumerate}
                 No explicit duration is allowed in symbols for the
                 second through last members of the xtuplet, the
                 duration having been determined by the first note.
\end{enumerate}

\medskip
_{xtuplet!inhibited beaming} _{beaming!in xtuplet}
Beaming of xtuplets is done automatically. If it is to be inhibited, add
the \textbf{a}lone option to the first-note symbol
(cf.~Section~\ref{sec:otherparams}).

\medskip
Fig.~\ref{fig:xtuplets} displays some examples of xtuplets, with the {\PMX}
coding given below the staff:

\begin{figure}[!htb]
	\begin{center}
           \includegraphics[scale=.82]%

	\end{center}
	\caption{Xtuplets}
	\label{fig:xtuplets}
\end{figure}

\bigskip
As was remarked at the end of Section~\ref{sec:preamble}, the
individual symbols of {\PMX} generally consist of one or several
characters strung together without spaces. In that sense, each note of
an xtuplet is considered to be \emph{a separate} {\PMX} symbol; so these
are separated by spaces as usual.

\bigskip\bigskip
_{xtuplet!non-standard bracket}
\label{p:sicherman}
A special, non-standard bracket can be printed for \emph{non-beamed xtuplets
only} with an addition to {\PMX} designed by Col.\ G.L.\ Sicherman. This
prints the xtuplet number not above or below the bracket, but in line
with it, as shown in Fig.~\ref{fig:xtupletsSich}. To invoke this, simply
add the option \texttt{AT} as a separate {\PMX} symbol anywhere in the
body of the source file: this will switch from standard to Sicherman
brackets \emph{for all xtuplets in the score}.

	\label{fig:xtupletsSich}
\end{figure}

\medskip
If you want to use this for specific xtuplets only or otherwise
customize your use of the option, you will have to use inline {\TeX}
commands, following instructions given in \verb#tuplet.tex# as comments.

\Note{To use the Sichermann option, the file
      \href{http://icking-music-archive.org/software/musixtex/%
            add-ons/tuplet.tex}{\texttt{tuplet.tex} }
      (available from the software section of the WIMA) must be
      installed in your {\TeX} system!
     }

\subsection{Chords}
\label{sec:chords}

_{notes!chordal} _{chords}
\emph{Chordal notes} are notes that share a common stem and have the
same duration. They are coded in {\PMX} as follows:
\begin{itemize}
   \item
_{chords!main note}
         One of the notes in the chord  is chosen to be the first note,
         the ``main'' note, of the chord. It can be any note in the
         chord; usually it is simplest
         \footnote{Sometimes, however, careful choice of the main note
                   can make an important difference. For example, if the
                   chord is beamed with other notes, the default height
                   and angle of the beam will be determined by the main
                   note of each chord. If a beam joining chords looks
                   bad, you can often fix it by changing which note acts
                   as the main one [\,of course there are other ways to
                   fine-tune beam parameters, as will be described in
                   detail in Section~\ref{sec:beams}\,].

                   So wise use of this freedom of choice is definitely
                   called for! For further details, consult
                   Section~\ref{sec:arpeggio} .
                  }
         to start either from the bottom up or the top down.

         The main note is written as usual and as described in
         Section~\ref{sec:notes} .
   \item All other chordal notes are denoted by separate symbols
         starting with \texttt{z} followed by a note name. The note name
         can optionally be followed by an accidental and an octave
         indicator (\texttt{+} or \texttt{-}), but no absolute octave is
         allowed. And no duration value is allowed either, as this is
         logically determined by the first note.

         If the main note is dotted, the dot is obviously `inherited'
         for all other notes as well, so writing another \texttt{d}
         would be redundant. But if you want to shift the dot of a
         chordal note, you \emph{must add} a \texttt{d}, followed by the
         shift parameters, as described on p.\pageref{shifts}.
   \item Normally {\PMX} will automatically set notes in a chord so that
         collisions are avoided (in a second, e.g.). If you don't like
         the result, you can shift the note by one notehead width to the
         \textbf{r}ight with \texttt{r}, or to the l\textbf{e}ft
         with \texttt{e} .
   \item The position of accidentals will also be adjusted automatically
         by {\PMX} so as to avoid collisions. But, as with single notes,
         you can shift accidentals of chord notes manually\,%
         \footnote{Note that if, in addition, you use a \texttt{+} or
                   \texttt{-} to denote a relative octave
                   (cf.~p.\pageref{p:relativepitch}), this sign must
                   come \emph{after} the shift parameter for the
                   accidental.
                  },
         using the parameters described on p.\pageref{p:accidentals}.

         If you manually shift \emph{any}\ accidental in a chord, then
         automatic shifting will be disabled for \emph{all}\ the
         accidentals in a chord, \emph{unless}\ you preface the shift
         parameter with \textbf{A} (e.g.~\texttt{zcsA<.5}), in which
         case the manual shift will be \textbf{a}dded to that applied
         automatically by {\PMX}.
   \item
_{chords!position of accidentals}
         \label{p:chordsoption}
         Another option that affects accidental positioning in chords is
         \texttt{Ao}~, entered in the main note symbol of a chord. It will
         force the accidentals in that chord to be posted in the order they
         come in the source (starting with the main note), each one as
         far to the right as it will go without crashing into a notehead,
         stem, or another accidental.
\end{itemize}

_{chords!stem length and direction} _{stems!direction forced}
The stem length and direction of a chord are controlled by the first
note, but may be manually overridden with \text{u} (\textbf{u}p) or
\texttt{l} (\textbf{l}ower) in the first note symbol.

\medskip
As decribed above, every chord note has its own note symbol. This means,
as always: no space within a note symbol, but at least one space
between the note symbols of a chord.

\subsubsection{Arpeggio} \label{sec:arpeggio}
_{chords!arpeggio}  _{arpeggio|see{chords}}

An \textbf{arpeggio} is, of course, simply a special form of a chord,
denoted by a vertical wavy line in front of the chord proper. To write
that in {\PMX}, place the symbol \texttt{?} after the symbols, with a
space as usual, for both the first and last note of the chord.

When doing that, you should remain aware of the fact that the wavy line
is generally understood as being played from the bottom up: lowest note
first, highest last.

\medskip
So far, so easy. There are, however, a few special cases to note:
\begin{enumerate}
  \item In an arpeggio, the wavy line often turns out to be crowded to
        the chord itself; this happens in particular when some of the
        chord notes have accidentals. In such cases one would want to
        move the arpeggio line away from the chord itself a bit, i.e.\
        to the left.
_{arpeggio!moving arpeggio line to the left}

        This is easily achieved by adding a \texttt{-} and an (unsigned)
        decimal number, without spaces, to one of the \texttt{?}
        designating the arpeggio --- it doesn't matter which one.
  \item Sometimes the composer may want to have the arpeggio played in a
        more virtuose way (on string instruments, in particular): the
        first 2 -- or even 3! -- of the chord notes simultaneously, as a
        double (or triple) stop, then the other chord notes as a true
        arpeggio.

        \medskip
        This can be done easily in {\PMX}: simply place the first
        \texttt{?} not after the starting chord note, but later, after
        one of the \verb#z...# notes.

        In this case is is even more important to remember the standard meaning
        of the wavy line in musical language that was just
        pointed out! So in general, it is best to stick with the order of
        the chord notes ``bottom to top'' unless you really know what
        you are doing.
  \item In piano music, it is quite common that an arpeggio is meant to
        go across the chords of both hands. This also is easily
_{arpeggio!across staves}
        implemented in {\PMX}\,%
        \footnote{To my knowledge, this feature of {\PMX} (available
                  from Version 2.503 on) has not been explicitly
                  documented in the official {\PMX} documentation.
                  I am very grateful to Andr‚ van Ryckeghem for drawing
                  our attention to this feature in one of his
                  contibutions to the WIMA ``Tips \& Tricks'' WEB page.
                 }:
        simply place the first \texttt{?} at the start of the left-hand
        chord and the second one \emph{at the end of the
        right-hand chord} --- as common sense would suggest!
\end{enumerate}

\bigskip\noindent
To see all this in examples, look at how the chords in
Fig.~\ref{fig:chords} were coded. When comparing this figure with its
code it should become obvious that care is called for when
producing chords with accidentals, and arpeggios in particular: some of
the chords in bars 1 and 2 look ugly, to say the least, and the arpeggio
line in bar 3 as well as the first one in bar 4 seem to be downright
violations of the standards of good typesetting practice.

\subsection{Grace notes}  \label{sec:graces}
_{grace notes} _{notes!grace notes}

A grace note symbol starts with a \texttt{G}.  It is entered in its
natural order, i.e.\ before the main note symbol for a normal grace,
behind the main note symbol for an after-grace . After
\texttt{G} comes any combination of the following options:

\begin{itemize}
   \item A single digit representing the number of notes\,%
         \footnote{The \emph{maximum} number of notes in a grace is not
                   fixed, but depends on circumstances
                   (cf.~Section~\ref{sec:limits}); but up to 16 is
                   usually safe.
                  }
         in the grace. The default is 1 .
   \item \texttt{m} (for \texttt{m}ultiplicity) and a digit,
         representing the number of flags or beams. The default is 1; 0 is
         allowed.
   \item
_{slurs!in grace notes} _{grace notes!slurs|see{slurs, in grace notes}}
         \texttt{s} (for \texttt{s}lur): this joins all notes of the
         grace to the main note. No \texttt{s} is needed in the main
         note symbol.
   \item \texttt{x} for a slash (only for single graces),
   \item \texttt{l} or \texttt{u} to force the direction of the stem(s)
         as desired.
\end{itemize}
Next comes the only required character, the first grace-note name.  No
time value must be entered, but, if needed, an octave (relative or
explicit) or an accidental can be given as in a normal note. Second and
later notes must follow immediately in sequence, set apart by spaces,
likewise without any time value, and without any intervening symbols.

\medskip
_{grace notes!`after'-grace}
`After'-graces (graces coming \emph{after} a main note) are entered
similarily to normal graces, with the same parameters as above; but in
addtion to the other parameters either an \texttt{A} (for
\textbf{A}fter) or \texttt{W} (for \textbf{W}ay-after) is entered,
before the grace note(s).

After-grace symbols associate the grace note(s) with the \emph{prior}
main note and are therefore entered \emph{after} the main note symbol.

\medskip
By default, {\PMX} will place graces or after-graces \emph{immediately}
before or after the main note, way-afters as far to the right as
possible before the next note or bar line.  If either type of
after-grace is slurred, the slur will start on the main note and end on
the last one in the grace.

_{grace notes!added space}
For a grace (\emph{not for an `after'-grace}), you can, if necessary,
add some space between the grace and the main note by inserting an
\texttt{X} followed by a unsigned decimal in the grace symbol\,%
\footnote{It doesn't matter where you insert this shift symbol, as long
          as it makes syntactical sense; to state this more simply: the
          \texttt{X}[\emph{n}] may \emph{not be inserted before a
          number} and \emph{not after the leading note} of the grace.

          \noindent
          This added space for a grace is indeed essentially a hard
          space, so that
_{spacing!hard space in grace}
          its name,
          \texttt{X} , is quite appropriate. And, as with almost all
          such cases, it is wise to keep in mind that `hard spaces' are
          what their name implies: a hard -- or brutal, if you will --
          last resort if nothing else seems to help. Used unwisely,
          adding a hard space to a grace is liable to produce rather
          ugly results, as is exemplified in Fig.~\ref{fig:grace}.
         }.

\subsection{Ornaments}  \label{sec:ornaments}
_{ornaments}

Symbols for ornaments are entered \emph{after} their associated note
symbol, separated, as usual, by a space\,%
\footnote{The ornament, although associated with a specific note, is
          considered a separate \PMX\ symbol.
         }.

The ornaments available in \PMX\ are listed in Table~\ref{tab:Ornamenti}
and are illustrated in Fig.~\ref{fig:ornament}.

\end{figure}

All except the staccato, tenuto, down fermata and parentheses will
appear above the staff; staccato\,%
\footnote{In fact, the only difference between staccato and pizzicato is
          the vertical positioning of the dot.
         }
and tenuto appear just above or below the note head, depending on the
stem direction, the parentheses at the level of the note head, of
course.

\medskip
The trill and segno symbol are special in that they may have additional
optional characters. Either trill symbol may include a decimal number to
specify the length of the wavy line indicating the duration of trilling,
in \verb#\noteskip#s . The default is 1 . Thus \texttt{oT0} will be a
\emph{tr} without any wavy line, and \texttt{oTt2} is a wavy line
of 2 \verb#\noteskip#s without any \emph{tr} symbol starting the wavy
line.

\medskip
A segno may only be entered in the first (lowest) voice.  It may be
immediately followed by a positive or negative integer, which indicates
a number of points that it will be offset horizontally; and it will
appear above every staff of the system.

\bigskip
_{ornaments!repeated}
Once the ornament type has been specified, most ornaments can be raised
or lowered from their default position by appending a signed integer to
the symbol, giving the vertical offset in \verb#\internote#s. Caesura
and breath may in addition have a signed number, giving the horizontal
shift from default in notehead widths. These two ornaments also differ
from the others in their default horizontal position, which is $0.5$
\verb#noteskip# past the note.

\medskip
An ornament can be automatically repeated on a series of consecutive
notes, provided the notes are all in the same input block. To activate
this feature, terminate the first ornament symbol with \texttt{:} . Then
every note in that voice will have the same ornament until a
note is followed by the repeat terminator \texttt{o:} .

\subsection{Beams}    \label{sec:beams}
_{beaming}

_{beaming!forced}  _{beaming!inhibited}
For the most part, \PMX\ automatically takes care of the details of
defining beams: selecting which notes are beamed together, and setting
the angle, direction, height, and \emph{multiplicity} (the number of
bars along the top or bottom). However, one may define a \emph{forced}
beam -- which overrides {\PMX}'s selection of which notes are beamed
together -- by surrounding the included notes with \texttt{[} and
\texttt{]}, being certain to separate these beam symbols: \texttt{[} and
\texttt{]} and their options, from the included note symbols with
spaces. Conversely, if {\PMX}'s selection is to beam notes, and you want
to inhibit this for a single note, add the option \texttt{a} to the note
symbol (cf.~Section~\ref{sec:otherparams}).

\bigskip
One may also wish to edit certain features of a beam even when {\PMX}'s
grouping decision would otherwise be acceptable; this is done by adding
some parameters to \texttt{[} and \texttt{]} :

_{beaming!parameters}
\medskip
The \texttt{[} can be followed, without space, by one or several of the
following options:

\begin{itemize}
  \item \texttt{u}, \texttt{l} or \texttt{f} will override {\PMX}'s
        selection of the direction of the beam:
        \begin{itemize}
          \item \texttt{u} makes the beam go \emph{above} the noteheads
                (\textbf{u}pper beam),
          \item \texttt{l} makes the beam go \emph{below} the noteheads
                (\textbf{l}ower beam), while
          \item \texttt{f} will \textbf{f}lip the beam from whatever
                \PMX\ would do automatically;
         \end{itemize}
   \item \texttt{h} forces the beam to be \textbf{h}orizontal;
   \item \texttt{m} followed by a single digit (1, 2, 3 or 4) forces the
         \textbf{m}ultiplicity of the beam;
   \item\texttt{j} \textbf{j}oins a beam grouping to a prior one started
         in another staff (cf.\ p.~\pageref{p:jumpbeam}).
\end{itemize}

The beam symbol constructed so far can be followed, without space, by
one, two or three consecutive integers, each preceded with \texttt{+} or
\texttt{-} :

\vspace*{-2ex}
   \begin{enumerate}
     \item first is an adjustment of the starting height, which
           thus determines the stem length of the first beamed
           note. It is given in \verb#\internote#s and may range
           from -30 to 30,
     \item the second is a slope adjustment (again in the range
           from -30 to 30),
     \item The third is an additional adjustment to the starting
           height, given in units of the beam thickness. It may
           range from 1 to 3 only. It always acts to
           \emph{increases} the stem length. This would only be
           used in rare cases, e.g.~to align consecutive
           horizontal beams which have internal multiplicity
           changes. An example is shown in Fig.~\ref{fig:beams}, bar
           \emph{f}.
     \end{enumerate}
Note that for technical reasons all three integers must always be given
\emph{with a sign} (even the last one, although it always is positive).
Note also that, since the meaning of these numbers is interpreted by
\PMX\ in their sequence, if you need only the second or only the third
number you \emph{must not omit} the preceding number(s), but rather give
explicit \texttt{0}'s for them.

\bigskip
Here are some further possibilities regarding beaming:
\begin{itemize}
  \item
_{xtuplet!beamed with other notes} _{beaming!in xtuplet}
        By default, xtuplets (cf.~Section~\ref{sec:xtuplets}) are set
        apart with their own beam.  To beam an xtuplet together with
        other non-xtuplets, just include it with the other notes in a
        forced beam.
  \item
_{beaming!rest within beamed notes} _{rest!in beam}
        Rests may also be included within forced beams, provided they
        are shorter than quarter rests, and of course that they come
        \emph{between} the first and last notes under the beam.
  \item
_{beaming!beamed groupings}
        Sometimes one may wish to define beamed groupings with subgroups
        joined by a single beam. The symbol \texttt{][} , standing alone
        between two note symbols inside a forced beam, causes the
        multiplicity to decrease to unity and immediately increase to
        its natural value for the next note. An example of this, as well
        as the beaming together with an xtuplet, can be seen in bar 2 of
        the trombone voice of Fig.~\ref{fig:agon}~: the two
        doubly-beamed groups connected by a single beam are generated by
        \texttt{[ c15 c c ][ c c cx3 c c ]} .
  \item
_{beaming!single-slope beam}
        Related to this is a
        \emph{single-slope beam group}, which is the same as described
        in the previous item except that there is no connecting  beam
        between the beamed subgroups. For this option, the beamed
        subgroups are separated by \texttt{]-[} standing alone between
        two notes inside the forced beam.
  \item
_{beaming!large jumps} _{beaming!up/down beams}
        If there are large jumps in pitch between
        notes in a beam within a single staff, as a matter of taste you
        may wish to start the beam for example as an upper one and end
        it as a lower.  {\PMX} will never do this automatically, but you
        can accomplish it by forcing the beam with appropriately
        modified up/down-ness, starting level, and slope.  If you use
        this technique, there are two details to note:
        \begin{enumerate}
           \item if there are any intermediate multiplicity changes,
                 they will only be handled properly if the initially
                 specified up-down-ness is consistent with the vertical
                 position of the intermediate notes involved\,%
                 \footnote{This is due to a fundamental technical
                           limitation of \MusiXTeX.
                          },
           \item for proper appearance in crowded scores you may wish to
                 insert hardspace or shifts as described in
                 Section~\ref{sec:spacing}.
        \end{enumerate}
        \pagebreak
  \item
_{beaming!staff-jumping}  \label{p:jumpbeam}
        Beams cannot normally jump staves. But if that is desired, start
        the beam normally in one voice, and terminate the part of the
        beam in that voice with \texttt{]j} . Then resume the beam in
        the other voice on a neighboring staff with \texttt{[j}, ending
        that part with the normal \texttt{]} . For staff-jumping beams,
        it's OK to have just a single note inside one or both of the
        partial beams. Each voice must, however, still have the right
        number of beats, so you will probably need to adjust the
        durations with blank rests after the first members of the beam
        and before the second.

        \smallskip
        With staff-jumping beams, some adjustment of the beam height and
        slope will usually be required. Also, sometimes the up/down-ness
        of the ending section must be overridden; you will know that
        this is necessary if on your first try the ending is shifted
        horizontally from the desired position. These editing commands
        may sometimes produce unexpected results, and some iteration may
        be required to get exactly what you want.

        \medskip
        An example of a staff-jumping beam is seen in
        Fig.~\ref{fig:jumpbeam}.

  \item
_{beaming!automatic forced beams}  \label{p:autoforcedbeam}
        If the option : (colon) is appended to the starting symbol
        \texttt{[} for a forced beam, then henceforth beams of the same
        length will be force-beamed similarly in that line of music
        until the end of the input block. Within an input block, the
        automatic forced beaming can also be stopped explicitly by
        starting a new regular forced beam.

        \begin{quote} But remember that {\PMX} is actually quite good at
          beaming notes in the manner a human musician would normally
          expect; so it will be necessary to use this facility only in
          the special cases when you want (or need) beaming different
          from what {\PMX} provides on its own. In such cases, consider
          this beaming automatism  as a kind of shorthand; as such, it
          will be really worth your while only when you want to repeat
          the same `non-orthodox' beaming an appreciable number of
          times. \end{quote} Regarding automatic forced beaming, you
          should also be aware of the following features:

          \begin{enumerate} \item As with regular beams, you can have
             notes of different durations beamed together in an
             automatic forced beam. The rule in that case is: in th e
             beams following the initial one, the next sequence(s) of
             notes with the \emph{same total duration time} as that of
             the notes beamed together initially will then be beamed
             together automatically. As usual, notes given without
             duration will `inherit' their durations from the most
             recent note with an explicit duration. All this is best
             seen in the following example:
             \begin{center}
             \includegraphics[scale=.82]{eps/autobeam} \qquad ,
             \end{center} which is coded as follows:
             \begin{verbatim}
                 d85 e   b a1 b c1 b a8
              [  d85 e ] b a1 b c1 b a8
              [: d85 e ] b a1 b c1 b a8
                 d85 e   b a1 b c1 b a8 /
                 g2d /
             \end{verbatim}

                Note how the automatic beaming ends at the end of the
                first input block. Leaving out the slash at the end of
                the fourth line would create havoc, because a full note
                cannot be beamed. But no slash is needed
                between the code for the first three bars.

          \item {\PMX} will never produce beams across bar
_{beams!forced across bar lines}
                lines. However, a somewhat fortuitous exception of this
                general feature of {\PMX} are staff-jumping beams, and a
                specific example of this can be seen in
                Fig.~\ref{fig:jumpbeam}. This is \emph{not an intended
                feature}, and its intentional use is not encouraged.

                \medskip
                A fortiori {\PMX} does not allow automatic
                \emph{forced-beaming} across bar lines. Any attempt to
                try that will always result in a {\PMX} error stop.
                Thus, if your automatic forced-beam pattern would cause
                a beam to cross a bar line, you have to terminate the
                automatic beaming properly before the end of the bar, or
                {\PMX} will stop with an error.
        \end{enumerate}

\subsection{Slurs and Ties} \label{sec:psslurs}
_{slurs} _{ties|see{psslurs}}

\subsubsection*{Pick a package} \label{sec:postscriptpackages}
\addcontentsline{toc}{subsubsection}{Pick a package}
_{dynamic marks!hairpin!length limit} _{hairpins|see{dynamic marks}}

By default \PMX\ will use \MusiXTeX's built-in, font-based slurs and
hairpins (crescendi and diminuendi, see Section~\ref{sec:dynamics},
p.~\pageref{p:dynamics} ff). To use these, you don't have to install any
more software. But they do have drawbacks: the fonts used by {MusixTeX}
for font-based slurs  come in fixed sizes and shapes and are therefore
often not flexible enough in complicated situations. In contrast, slurs
and hairpins produced with the help of the PostScript language overcome
many of the shortcomings of their font-based counterparts.

_{slurs!PostScript} _{PostScript!slurs, ties and hairpins}
There are two independent ``third-party'' packages that provide
{\MusiXTeX} and {\PMX} users with PostScript-based slurs, ties, and
hairpins:
\begin{description}
   \item[\emph{Type K} --] \label{sec:pss-K}
_{Kneifl, Stanislav}
         This package was written by \textbf{Stanislav Kneifl}. It is
         directly supported by \PMX\ and will be the focus of any future
         \PMX\ enhancements. Detailed instructions for its use are given
         in the corresponding paragraph below.
   \item[\emph{Type M} --]
_{Morimoto, Hiroaki}
         This package, by \textbf{Hiroaki Morimoto}, is somewhat more
         flexible when used directly in {\MusiXTeX}, but it requires
         the \textbf{Metapost} package to be installed in the {\TeX}
         installation. These are not directly supported by {\PMX}, but
         are advertised to be fully compatible with {\MusiXTeX}'s
         default font-based slurs. From {\PMX}'s standpoint they are not
         different from font-based slurs, and the same options and
         features that apply to font-based slurs should apply as well to
         these.
\end{description}

Both PostScript slur packages provide excellent slurs, ties and
crescendi. \label{p:usepsslurs} In fact, for simple slurs, you can
hardly discern the differences between the three possibilities, as can
be seen in Fig.~\ref{fig:psslurs1} --- although type M slurs are generally
somewhat flatter, indeed. On the other hand, for steep and long slurs,
the difference is appreciable, as can be seen in the example of
Fig.~\ref{fig:psslurs2}.

\end{figure}

\bigskip
Here are some additional factors to consider when deciding which type of
slurs and hairpins to use with {\PMX}:
\begin{itemize}
  \item True ties, which are shaped differently from slurs, are only
        available with Type K\,%
        \footnote{In {\MusiXTeX}, font-based
                  true ties are actually available; but they were never
                  incorporated in {\PMX}, now being superceded by type K
                  slurs.
                 }. In all cases, the starting and ending
        positions are different for ties and slurs\,%
        \footnote{The ends of an ordinary slur are centered horizontally
                  above or below the notehead, while tie ends are
                  shifted inboard and closer to the midheight of the
                  notehead.
                 }.
  \item Font-based hairpins cannot wrap over a line break, but the
        PostScript ones can.
  \item Font-based hairpins cannot be longer than 68 mm.
  \item With either postscript package, the resulting markings do not
        show up on the screen if you view the score with one of the
        commonly used DVI viewers such as \textbf{XDVI} or \textbf{YAP}.
        To see them, you have to first produce a PostScript file from
        the \texttt{dvi} file (using, for example, \textbf{dvips}), which
        you can then view on the screen and print on your printer using
        \textbf{Ghostview} or some other such program. But if you use
        Type 1 PostScript fonts, as was recommended in
        Section~\ref{sec:psslurs}, you will have all this software at
        hand anyway!
_{PostScript!fonts}
\end{itemize}

Detailed instructions for installing the Type K or Type M packages are
given in Section~\ref{sec:pss-K} .

\subsubsection{General slur usage}
_{slurs!general usage}

This subsection explains commands that apply to all types of slurs,
followed by separate subsections describing operational features
specific to either font-based or Type K slurs, and finally a subsection
on the use of Type M slurs.

\medskip
Here are the {\PMX} symbols that normally define slurs or ties, except
for slurs to or from graces\,%
\footnote{Recall that the slurring of grace notes is defined
          entirely within the the grace symbol, as described in
          Section~\ref{sec:graces}.
         }:
\begin{itemize}
   \item An opening parenthesis, `\texttt{(}', begins a slur, and a
         closing parenthesis, `\texttt{)}', ends it; similarly, an
         opening brace, `\verb#{#', begins a tie, and a closing brace,
         `\verb#}#', ends it.   The opening parenthesis/brace is placed
         \emph{before} the first note, and the closing parenthesis/brace
         \emph{after} the last note of the slur or tie. As always, these
         symbols (including options, see below) are separated from notes
         and other symbols by spaces.
         \footnote{Braces -- and similarly the tie toggles described
                   subsequently -- , although legal with all types of
                   slur, are really useful only with Type-K slurs, since
                   only with these they will produce a true tie.
                  }
         \item Alternatively to parentheses, you can use the letter
               \texttt{s} (for \textbf{s}lur) both to begin \emph{and}
               end a slur; but these come \emph{after} both the
               beginning \emph{and} ending note. This is thus a
               \emph{toggle}, turning a slur off if it's on, and
               starting a new one otherwise.

               For ties (instead of slurs), use the letter
               \texttt{t} (for \textbf{t}ie), also a toggle.
               \label{p:tslur}
\end{itemize}

Note that slurs or ties may end on a rest\,%
\footnote{If you happen to think that this would be musically
          meaningless, you are wrong. Just watch a really good pianist
          (or conductor, for that matter) ending a piece, say in pp. It
          ain't over until the fat lady has really finished singing:
          until she is really \emph{completely} \emph{done} with taking
          her hands off the keyboard! In other words: she visibly (and
          audibly!!) plays the slur over the final rest.
         },
but they may \emph{not start} on one.
_{slur!ending on rest} _{tie!ending on rest}
The default ending height of the
tie (or slur) in that case will be that of the note on which it started
(in other words, it will be horizontal); but you can vary that
explicitly in the usual way.

\bigskip
Often you need to open a slur or tie while another one is already open
\emph{in the same voice}, e.g., with tied chords, or if a second slur
connects a subgroup of notes within a longer slur. In such cases, {\PMX}
needs to be told which slur is which. For this purpose, the slur opening
character [ \texttt{s}, \texttt{t}, \texttt{(} ] can
optionally be followed by a single-character ID code [ \texttt{0-9},
\texttt{A-Z} ] to identify that particular slur. To close that slur,
insert the ID code right after the corresponding \emph{closing}
character [ \texttt{s}, \texttt{t}, \texttt{)} ]. If an ID code is
used, it \emph{must} be the second character in the symbol. You cannot
use any ID that is already in use on a slur or tie for a new slur or
tie. See Fig.~\ref{fig:bloch} for an example\,%
\footnote{The example uses Type K slurs.
         }.

\end{figure}

\bigskip
Normally, you can leave further details of slur appearance to {\PMX};
the result will usually satisfy. If not, you can change some features
manually by additional options which go right after the initial character
and any ID code, as usual \emph{without} a space,:

\begin{itemize}
_{slurs!additional options}
   \item The default vertical position above or below the note heads
         can be overridden with
         \begin{itemize}
            \item \texttt{u} (\textbf{u}pper),
            \item \texttt{l} (\textbf{l}ower) or, equivalently,
                  \texttt{d} (\textbf{d}own).
         \end{itemize}
   \item The starting or ending point can be shifted from its
         default by entering one or two explicitly signed numbers: the
         first, which must be an integer, gives the vertical shift, in
         \verb#\internote#s; the second, which may be decimal, the
         horizontal offset, in notehead widths.
   \item A dotted slur is obtained by adding the option \texttt{b} (for
         \textbf{b}roken) in the symbol that starts the slur
         (cf.~Fig.~\ref{fig:dottedslur}).

\paragraph{Slurs for staff-jumping beams} \text{} \\[-2ex]
_{slurs!with staff-jumping beam}

Often -- in piano music in particular -- when you have a staff-jumping beam
(cf.~p.\pageref{p:jumpbeam}), you may want to join the two parts by a
slur as well. {\PMX} will, however, get very confused if you try to put
the beginning slur symbol in one staff and the corresponding ending
symbol in a different staff; both slur symbols \emph{must always be in
the same staff}. The solution is to put the ending slur symbol after
the invisible rest; but do so carefully: even though the invisible rests are
indeed invisible, {\PMX} accounts for the horizontal space it would need
for visible rests, and that determines the length of the slur. So if you
want to avoid awkwardly adjusting the length of the slur by hand, you
should subdivide the invisible rest appropriately so that one part of it
will be at the note of the other staff where you want the slur to end.
The vertical position of the slur end will have to be done manually.
Fig.~\ref{fig:jumpslur} shows an example.

\subsubsection{Invoking and using Type K slurs}  \label{sec:pss-typeK}
_{slurs!Type K usage} _{PostScript!slurs, ties and hairpins}

To activate the Type K package, all you need to do is to add a line in
the header of the {\PMX} source after the preamble, containing the
symbol \texttt{Ap}\,%
\footnote{For further details on the use of \texttt{A} see
          Section~\ref{sec:A} .
         }.

\bigskip
For type K slurs, some optional parameters can be used in the slur
symbol to change the shape of the slur:
\begin{itemize}
_{slurs!additional options}
   \item an \texttt{f} (for \textbf{f}latter) will flatten the slur a
         bit, while
   \item \texttt{h, H} or \texttt{HH} (for \textbf{h}igher) will
         increase the slur's curvature by increasing degrees, thereby
         raising (or lowering) its middle.
\end{itemize}
These parameters can be used in either the starting or the ending slur
symbol. They \emph{do not work with ties}, i.e.\ with symbol \texttt{t},
and {\PMX} will complain if you try that. Examples are given in
Fig.~\ref{fig:kslurs}.

\begin{figure}[!htb]
	\begin{center}
           \includegraphics[scale=.82]{eps/kslurs1.eps}

           \includegraphics[scale=.82]{eps/kslurs2.eps}
	\end{center}
	\caption{Shape variations in type K slurs}
	\label{fig:kslurs}
\end{figure}

\medskip
The Type K package contains {\TeX} macros that activate or deactivate an
automatic vertical adjustment of slurs or ties to avoid tangencies with
staff lines. In {\PMX} these adjustments are switched off by default,
because they may alter the endpoint positions from what you would
normally expect. However, if you wish to use them, they may be switched
on or off globally at the start of any input block, and locally with
options to individual slur or tie commands.

To activate these adjustments globally (or deactivate, if previously
activated), at the beginning of any input block enter \texttt{Ap+s} (or
\texttt{Ap-s}) for slurs, and \texttt{Ap+t} or (\texttt{Ap-t}) for ties.
To activate them for one-time use only, simply include \texttt{p+t} or
\texttt{p+s} as an option in the symbol for the affected slur or tie. No
deactivation is then needed.

You can also sequentially increase (\texttt{Ap+c}) or decrease
(\texttt{Ap-c}) the default curvature of slurs or ties (again at the
beginning of any input block), so that the result is cumulative. But
after the cumulative change has reached ``HH'' or ``ff'', it will remain
there, and nothing more will happen.

An example is given in Fig.~\ref{fig:kslurtweaks}. The distinctions are
fairly subtle; but some would see the adjusted markings as more pleasing
since on close inspection they clearly avoid tangencies with staff
lines.

\end{figure}

\paragraph{Line-break tie options} \text{} \\
_{line break!tie options} _{slurs!across line break}
There are two options that only affect ties that span line breaks:
\begin{enumerate}
   \item by default a full tie is drawn at the beginning of the second
         line in such cases. There is a global option, \texttt{Ap+h},
         which tells {\PMX} to use \emph{half ties} -- which are
         flattened at their left-hand ends -- on the second line, but
         \emph{only} in cases where the second tie segment is shorter
         than 15 pt. This option may be cancelled with \texttt{Ap-h} ,
   \item the second option -- which should not be used together with the
         first one! -- affects \emph{both} the first and second segments
         of linebreak slurs and ties. It is the global option
         ~\texttt{Apl}. It alters two defaults to give what some might
         consider an improved appearance: first, it causes the first
         segment to be drawn as a normal tie, whereas by default it has
         a different shape than a normal tie; second, it moves the
         starting point of the second segment a bit to the left.

         \medskip
         The \texttt{Apl} option has been enhanced since {\PMX}
                   version 2.411; the main new feature is that it now
                   works for slurs as well as for ties. Other
                   enhancements are more subtle; read the description of
                   these in the announcement text for version 2.411, given
                   here:
                   \begin{quotation}
                      ``\texttt{Apl} in the preamble now activates
                        special treatment of line-break slurs and ties
                        (before, \texttt{Apl} only affected ties.).

                      ``Specifically, it enables tweaking the ending

                        curvature of either, or both. [You must have
                        musixps.tex available to {\TeX}!] With

                        additional PMX slur start or ending commands are
                        required). Vertical/horizontal tweaks to the
                        start of the seg 1 and the end of seg 2 are
                        handled as before. Vertical/horizontal tweaks
                        for the end of the seg 1 and start of seg 2 are
                        entered as options in the otherwise normal
                        command that starts the slur/tie. The option for
                        the end of seg 1 starts with "s" (for sever or
                        split), then the usual one or two signed
                        numbers, then a second "s" and one or two more
                        signed numbers for the start of seg 2.

                      ``The usual curvature options \texttt{h},
                        \texttt{H}, \texttt{HH}, \texttt{f}, if included
                        in the starting command for a linebreak slur,
                        will apply to seg~1, and if in the closing
                        command, to seg~2. Of course, if the slur/tie
                        does not come at a linebreak, the special
                        position tweaks (those after the "s" option)
                        will all be ignored, and the curvature tweaks on
                        the closing note take precedence (as before).''

      becomes too short to be clearly visible.

The global options mentioned (and in fact any of the other global
options to be described later) can be combined into a single symbol,
e.g., \texttt{Ap+sl}.

\subsubsection{Use of Type M Slurs and Ties} \label{p:useMslurs}
_{slurs!Type M usage}  _{PostScript!slurs, ties and hairpins}

In contrast to the type K slurs, type M slurs are not explicitly
supported by {\PMX}; as a consequence, you have to do some things
manually. But it's not difficult:
\begin{itemize}
   \item
_{\textbf{musixpss}}
         The first step is to insert into the header of your {\PMX}
         source file the following line \\
         \text{\hspace*{10em}} \verb#\\input musixpss\relax\# \qquad .
    \item
To process a {\PMX} file with type M slurs, three extra steps are
needed to produce a printed musical score. Here is the full sequence of
processing steps, for a file named \verb#my_opus#:

\begin{center}
\begin{tabular}{r@{\qquad}ll@{\qquad\qquad}l}
       & command         &                & resulting new file(s)   \\  \hline
       &                 &                &                         \\
   0.  & text editor     &                & \verb#my_opus.pmx#      \\
   1.  & \verb#pmx#      & \verb#my_opus# & \verb#my_opus.tex#      \\
   2a. & \verb#tex#      & \verb#my_opus#

\end{tabular} \end{center}
\end{itemize}

\subsubsection{Special considerations for font-based slurs}
_{slurs!font-based}

You should study this section if you choose not to use Type K PostScript
slurs.

\medskip
The slur command \texttt{t} (cf.~p.\pageref{p:tslur}) has been retained
for backward compatibility with earlier {\PMX} versions. As already
mentioned, with font-based slurs it does \emph{not} provide a true tie
at all, and it doesn't alter the positions of the endpoints either; in
fact, it differs from \texttt{s} or \texttt{(} only in the following
ways:
\begin{itemize}
  \item ID codes cannot be used with font-based \texttt{t}-slurs.
  \item If a \texttt{t}-slur starts or ends on the same note as an
           \texttt{s}-slur, the former will be moved away from the
           notehead to avoid a collision. This only works if neither
           slur has an ID code.
\end{itemize}
The shape of font-based slurs can be changed with options to the
\texttt{s} or \texttt{)} command as follows:
\begin{itemize}
  \item at the slur termination only, you must first enter two signed
        numbers that define a position shift as described earlier. Enter
        a zero for either or both if you don't want the shift,
  \item next, enter a signed, nonzero integer which specifies a vertical
        adjustment to the mid-height of the slur in \verb#\internote#s,
  \item if you want to alter the starting or ending slope, enter a
        \texttt{:} (colon), then
        \begin{enumerate}
           \item a signed integer for the alteration to the starting
                 slope, then
           \item a signed integer for the alteration to the ending
                 slope.
        \end{enumerate}
\end{itemize}
These numbers are passed directly as arguments of the {\MusiXTeX} macros
\verb#\midslur# (if only one is given) or \verb#\curve# (if there are
three).

\bigskip
If you want to \emph{simulate a tie} with font-based slurs -- {PMX} does
not proved true ties with font-based slurs! -- include the option
\texttt{t} in both the starting and ending command for the slur\,%
\footnote{For reasons of backward compatibility, it is legal
          to specify a tie with the symbol \texttt{st} or \texttt{(t}
          even when PostScript ties are activated. In that case, these
          symbols are fully equivalent to simply using \texttt{t} .
         }.
This will draw a slur with altered endpoint positions.

\subsection{Dynamic Marks}     \label{sec:dynamics}
_{dynamic marks} _{D symbol@\texttt{D} symbol}

{\PMX} has a very simple tool for inserting virtually any dynamic mark
in a score. Its \texttt{D}ynamics symbol is a \texttt{D}, followed one
of 3 types of parameters, optionally followed by position shifts:
\begin{enumerate}
   \item \textbf{A standard dynamic mark :} this can be any one of the
         following:
         \texttt{pppp, ppp, pp, p, mp, mf, f, ff, fff, ffff, sfz, fp}.
   \item
_{dynamic marks!hairpin} _{crescendo|see{dynamic marks}}
_{decrescendo|see{dynamic marks}}
         \textbf{A crescendo/diminuendo :} \texttt{<} or \texttt{>}.
         These crescendo/decrescendo marks -- aptly named ``hairpins''--
         are \emph{toggles}, i.e.\ the first \texttt{D<} starts the
         crescendo, and the next \texttt{D<} ends it; similarily for
         \texttt{D>}.
   \item
_{dynamic marks!textual}
         \textbf{Arbitrary text :} \texttt{"\dots\"}, where \, \dots \,
         stands for any text string, e.g.~\texttt{D"}molto
         espressivo\texttt{"}.The text will be set in italics unless
         another \TeX-style font specification is included.
\end{enumerate}

All dynamics symbols go \emph{after} the note to which they refer (so
e.g.~\texttt{g Dpp} will write a pianissimo g). Hairpin marks
must be contained \emph{completely within the same input block}\,%
      \footnote{If need be (e.g.\ for crescendi/decrescendi across bar
                lines), you can adjust the position and length of a
                crescendo/decrescendo by adding position shifts as
                described.
               }

\Note{Since all dynamic marks go \emph{after} a note, a fortiori they
      should \emph{never come at the very beginning of an input block}.
      This is important to keep in mind because \PMX\ does not
      necessarily give an error message, but can produce rather strange
      results, often at remote places in your score (what Knuth calls `a
      weird error'), so the true source of the error may be hard to
      detect. You can usually get a hint that something went wrong if
      \PMX\ has produced a backup file of your source --- without any
      apparent reason!
     }

\medskip
The default position of any dynamic mark or text entered with the
\texttt{D} symbol is just below the notehead, stem end, or bottom staff
line, whichever of these is lowest. There are numerous context-sensitive
automagic adjustments to the positions of all the dynamics symbols. If
you don't like the result you can add position shifts to the dynamics
symbol: a signed integer for a vertical shift (in \verb#\internote#s),
then -- optionally -- another signed number for a horizontal shift (in
notehead widths).

\medskip

There can be a combination of dynamic marks at a single note\,%
\footnote{It doesn't make sense, of course, to have 2 different standard
          dynamic marks on the same note, and {\PMX} will complain if
          you try that.
         }.
Since these are distinct {\PMX} symbols, they must be separated by
spaces and must come in the right order, e.g.\
\begin{center}
[\emph{some notes}] \texttt{D<} [\emph{more notes}] \texttt{D< Dffff D>}
[\emph{more notes}] \texttt{D>}
\end{center}

\bigskip
If you aren't using PostScript slurs, there are some restrictions on
hairpins which are due to {\MusiXTeX}'s use of font-based hairpins: they
cannot be longer than 68mm, they cannot wrap over a system break, and
they must be horizontal. Finally, only certain specific lengths are
available, so some horizontal position tweaking may be needed,
especially when standard dynamic marks and hairpins are combined.
These restrictions don't apply when using one of the PostScript slur
packages; PostScript hairpins will then be used without any further
 \label{p:dynamics}
intervention\,%
\footnote{For details on invoking PostScript slurs, ties and hairpins
          cf.\ Section~\ref{sec:psslurs} ff.
         }.
Fig.~\ref{fig:dynamics} (a fragment from the \emph{Pathetique} by
Tschaikowsky) shows some examples\,%
\footnote{Fig.~\ref{fig:dynamics} was obtained using the PostScript slur
          package type K.

	\end{center}
	\caption{A clef change}  \label{fig:clefchange}
\end{figure}

As was noted in Section~\ref{sec:preamble}, the clef for each instrument
is given in the preamble (cf.~p.~\pageref{p:clefs}). A clef change in
mid-stream, however -- frequently occurring in piano music --, is
signaled by a \texttt{C} followed by a single lower-case letter, as
illustrated in Fig.~\ref{fig:clefchange}.

\bigskip
_{clefs!change with two voices in a staff}
When there are two voices in a staff, the clef change command must be
given in the \emph{first (lower) voice}; if it is entered in the second
voice, {PMX} will \emph{silently disregard} the clef change completely.
The clef change holds for all voices in a staff, of course.

\medskip
A logical effect is worth mentioning: when, before the clef
change, there is a note the duration of which extends beyond
the point of the clef change, its clef does not change.
Fig.~\ref{fig:clefchgtwo} shows an example of such a situation.
\begin{figure}[!htb]

\end{figure}


\subsection{Octaviation} \label{sec:octaviation}
_{octaviation}

When in a voice the pitch of a number of notes extends far beyond the
staff, resulting in an excessive number of ledger lines, readability is
usually improved by using an `octaviation' notation: an
horizontal line above the staff, starting with an ``\emph{8}'' or
``\emph{8va}'', indicates that the notes under this line are to be
played an octave higher than printed, and similarily ``\emph{8 bassa}''
or ``\emph{8va bassa}'' indicate an octave lower.

\medskip
In the present version, {\PMX} does not provide a notation for this, so
you will have to take recourse to inline {\TeX} coding. For an example
see Section~\ref{sec:tricks}.


\subsection{Figured bass (basso continuo)}  \label{sec:bassocontinuo}
_{figured bass} _{basso continuo|see{figured bass}}

{\PMX} lets you introduce the basso continuo notation (`figured bass')
very simply, as illustrated in the example of Fig.~\ref{fig:poppea}, which
is the basso continuo of an excerpt of the famous aria ``\emph{Pur ti
miro}'' that concludes the Monteverdi opera \emph{L'Incoronazione di
Poppea}. Here are the rules:

\begin{itemize}
   \item Figure symbols are entered -- as plain numbers\,%
         \footnote{As of {\PMX} version 2.520, the numbers usually
                   needed in figured notation, namely 2, 4, 5, 6 and 9,
                   are available in a different graphic design with
                   perhaps a more baroque-like look.

                   If you want to use these, add an `\texttt{s}' after
                   the {\PMX} string of every figure which you want to
                   appear in that form.

                   Note that for this to work properly, you must have
                   the special fonts for these numbers installed. You
                   will find \texttt{figbas.zip}, which provides these
                   fonts, in the
                   \href{http://icking-music-archive.org/software/%
                   musixtex/add-ons/figbas.zip}{WIMA} software page.
                   \texttt{figbas.zip} contains 2 files that can be of
                   help with the installation: \texttt{README} and
                   \texttt{test.tex} .
                  } --
         \emph{after} their associated note symbols, with
         a space, as usual. As of {\PMX} version 2.517, they are allowed
         in two staves, the first (lowest) staff and any other one.
         Enter the characters as they would appear from \emph{top to
         bottom}, e.g.\ \verb%64% [\,6 over 4\,], or \verb%642% [\,6
         over 4 over 2\,].
   \item Accidentals that modify a number \emph{must} be entered
         \emph{before} the number. Note that the characters that
         signify accidentals are different here than for notes: flats
         are written as `\verb#-#' (minus), sharps as \verb&#& , and
         naturals as \verb%n% . For example, \emph{sharp third} is
         \verb&#3& (or simply \verb&#&, in the standard shorthand),
         \emph{six} (over) \emph{flat five} is \verb%6-5%, and
         \emph{sharp six} (over) \emph{4} is \verb&#64& .
   \item For each staff with figures, {\PMX} positions all the figures
         within each system below the staff with their tops at the same
         level. If you want to change this vertical position default,
         you have two possibilities:
     \begin{description}
         \item[to lower a figure symbol:] prefix the figure symbol
              -- \emph{no space!} -- with one or several `\verb#_#'
              (underscore). Each underscore will lower the figure symbol
              by 4 lengths of \verb#\internote# ,
         \item[to raise a figure symbol :] \emph{append} the figure
              symbol -- \emph{again no space} -- with a `\verb#+#' (plus)
              followed by an integral number for the number of
              \verb#\internote# lengths by which to raise the figure.
     \end{description}
         The two options can be combined to provide full control over
         the vertical position of the figure symbol.
   \item If you want a figure symbol to align horizontally in
         the second tier, insert a `\verb&_&' (underscore) as placeholder
         for the top tier, before the one you want to go on the second
         tier (cf\ the sharp in bar 16 of Fig.~\ref{fig:poppea}).
   \item Sometimes you may need to enter a figure when there's no bass
         note sounding. To do this, \emph{precede} the figure symbol
         with three additional characters, \verb%x%[\emph{n}][\emph{m}].
         Here \emph{n} is a single-digit repeat count, and \emph{m} is a
         single-digit duration time value, i.e., \verb#0,2,4,8,1# or
         \verb#3# . This will offset the figure from the associated note
         by the specified duration value. For example, if the lowest
         voice contained \verb%c03 x3465%, there would be a whole-note
         c, and 3 quarter notes later a figure 65 below the staff
         (cf.~Fig.~\ref{fig:poppea}, bars 2, 4, 6, 8, 10 and 14).
   \item
_{figured bass!continuation}
         There is also a \emph{continuation} symbol, viz.\ a \verb&0&
         (zero) followed immediately by an unsigned number.  This
         produces a horizontal line under the bass note, starting just
         to the left and extending to the right by the given number of
         \verb&\noteskip&'s (cf.~Fig.~\ref{fig:poppea}, bars
         9, 11, 16 and 17). The height and length of the line are set by
         the current note's level and \bs\texttt{noteskip}
         respectively\,%
         \footnote{If \bs\texttt{noteskip} changes, or if an unfigured
                   note drops below the starting level before the line
                   ends, it is possible to trick {\PMX} by entering
                   separate \texttt{0}[\emph{n}] symbols under each
                   consecutive note: {\PMX} will automagically join them
                   together at the lower height (thanks to Werner Icking
                   for this idea).

                   For an explanation of the special {\PMX} coding in
                   Bar 16 of Fig.~\ref{fig:poppea} see
                   Section~\ref{sec:tricks} .
                  }.
         These can be mixed in with other figures to produce vertical
         stacks.  If another figure follows in the same symbol, use
         {\tt:} as a separator. For example, a continuation line over a
         3 would be coded as \texttt{01:3} .

_{F symbol@\texttt{F} symbol} _{\textbf{scor2prt}}
If there are figured bass commands in a {\PMX} file, but you want them
all to be ignored, then enter the symbol \texttt{F} in the header. This
feature is most useful in the form \texttt{\%1F}
(cf.~Sec.~\ref{sec:scor2prt}, which makes a separate bass part with
no figures, e.g.~for a violoncello part.

\bigskip
Figured bass symbols will not be altered in any way under transposition
by {\PMX} (cf.~Sect. \ref{sec:transpositions}). There is no universal
set of interpretations of figured bass symbols, so no automatic
transposition is possible.
_{transposition!not with figured bass}

\medskip
_{figured bass!2-digit figures}
{\PMX} does not admit 2-digit basso continuo figures. This is the
notation of some old editions; if you want to use it, you will have to
resort to inline {\TeX} coding (cf.~Section~\ref{sec:inlineTeX}).
There is an example for this in the Caccini aria in the Appendix
(Sec.~\ref{sec:Caccini}).

\section{Commands That Affect All Voices}   \label{sec:pmxcmds}
_{\PMX!commands for all voices}

Unless indicated otherwise, the commands dealt with in this section
affect all staves in a score. They must be entered only \emph{in the
first (lowest) voice in the first (lowest) staff}.

\medskip
_{\textbf{scor2prt}}
Such commands will automatically be transferred from score to parts when
separate parts are generated by \textbf{scor2prt}
(cf.~Section~\ref{sec:scor2prt}).

\subsection{Single bars, Double bars, Repeats etc.}  \label{sec:bars}
_{bar lines} _{bar lines!single, double, repeat} _{repeats|see{bars}}
_{R symbol@\texttt{R} symbol}

In keeping with general typesetting practice, {\PMX} will by default
produce
\begin{itemize}
   \item a single bar line at the beginning of each system after the
         first, unless there is only one staff per system,
   \item a single bar line at the end of each bar except the last one in
         a movement or the entire score,
   \item the common ending bar line (thin-thick double bar line) as the
         last bar line of a movement or the entire score.
\end{itemize}

_{\textbf{scor2prt}} _{\textbf{scor2prt}!placement of bar symbols}
The user can, however, override these defaults -- except the first one
-- by a bar symbol, viz.\ an \texttt{R} followed by one of the
parameters given in Table~\ref{tab:bars}. If you are going to make parts
from your score (cf.~Section~\ref{sec:scor2prt}), you \emph{must} place
bar symbols either before the first note in an input block or after the
last one; otherwise \textbf{scor2prt} may behave erratically. Using two
bar symbols in succession doesn't make sense and will produce
unpredictable results.
\footnote{If you are using \texttt{|} marks at the end of bars, a repeat
          must always go \emph{before} the \texttt{|}, or the next line
          must follow in the same input block. In other words: while
          \texttt{Rr | /} will not result in an error, it will produce a
          thin bar line only.            \label{p:repeats}

          \smallskip
          There is a simple consequence: avoid using \texttt{|}
          altogether, at least in connection with \texttt{R} symbols.

\caption{Parameters of the bar symbol \texttt{R}} \label{tab:bars}
\end{table}

\medskip
Here are further comments on some particular bar symbols:
\begin{itemize}
   \item \texttt{Rb} forces a single bar before a movement break, where
         the default would be a double bar. This can be useful, for
         example if you change the number of instruments, which {\PMX}
         will allow only at a movement break, but you don't want it to
         \emph{look} like a movement break.
   \item \texttt{Rz} will cause an invisible bar line at the end of the
         current system. It can be used together with blind meter
         changes (cf.~Section~\ref{sec:meterchg}) when you want to split a
         bar across a system break.
   \item if a left-right repeat (\texttt{Rlr}) comes at a system break,
         {\PMX} will automatically split it in two.
   \item \texttt{Rdl} is the same as a left repeat
         (\texttt{Rl}) except at a system break: there the first system
         is ended with two thin lines, and the left repeat sign goes to
         the beginning of the next system.

         \medskip
   \item Finally, a general remark is in order regarding the \texttt{R}
_{R symbol!placement at begin of block}
         symbols that designate repeats, double bars etc.\
         (\texttt{Rl,Rr,Rlr,Rd, RD,Rdl,Rb,Rz}). To avoid conflicts with
         \textbf{scor2part}, you should \emph{always}
         place any \texttt{R} command before the first note in an
         input block. This is always possible except at the very end of
         the whole piece. Otherwise, there is always a following input
         block where the command can (and should) be placed.
\end{itemize}

\medskip\noindent
Fig.~\ref{fig:bars} gives some examples.

\Note{On some special occasions, you may want dashed or dotted barlines
      instead of the regular ones. For this and similar purposes, there
      is a very good and easy-to-use package by Rainer Dunker:

\subsection{Volta}  \label{sec:volta}
_{volte} _{dacapo|see{volte}} _{repeats|see{volte}}  _{V
symbol@\texttt{V} symbol}

The two versions of the ending of a repeated section of music, called
`volte' in musical parlance\,%
\footnote{The term `volta' is, of course, Italian, and `volte' is the
          Italian plural  of `volta'.
         },
are denoted by a symbol starting with a \texttt{V} (for \textbf{V}olta)
in {\PMX}. {\PMX} needs to know where each volta starts and ends, how
the ends are shaped, and what text is to be included under each volta. A
string parameter to the \texttt{V} is used to convey this information:
\begin{itemize}
   \item to signal the \emph{start} of the first volta, add a text
         string (usually just a \texttt{1}) that doesn't start with
         one of the characters \texttt{b}~, \texttt{x}~, or any literal
         spaces\,%
         \footnote{Actually you can include a space by using the {\TeX}
                   space symbol \~\ instead of a blank.
                   _{\TeX!space symbol}
                  }.
         {\PMX} will print append a period to the text string,
   \item to signal the \emph{end} of a volta and the start of the
         second volta, use a \texttt{V} with a text string that
         \emph{does} start with either the character \texttt{b}~ or
         \texttt{x}~. If \texttt{b}~ is present, a volta symbol ending
         with a vertical stroke will be printed (\textbf{b}ox), while
         \texttt{x}~ will print the ending \emph{without} a vertical
         stroke (no bo\textbf{x})\,%
         \footnote{Note that the characters \texttt{b}~ or \texttt{x}~
                   can appear anywhere in the text string and will
                   \emph{not appear in print}.
                  }.

         Often composers will write out only the first ending of a
         repeated section of music, and simply continue play, dropping
         the first ending after the repeat. With {\PMX}, the notation is
         analogous: simply end the first volta, with either \texttt{Vb}
         or \texttt{Vx}, without adding a second volta.

         On the other hand, if one volta starts where another one ends,
         the symbols ending the first and starting the second volta can
         be combined into one, e.g.~\texttt{Vb2}~.
\end{itemize}

\medskip
Other rules governing volte are:
\begin{itemize}
   \item Volte should be placed at the beginnimg of an input block, in
         the first (lowest) voice of the first (lowest) staff, before
         the first note if it's the start of a volta, or after the last
         note if it's the end of a volta.
   \item
_{volte!with \textbf{scor2prt}}
         If you will be making parts from the score using
         \textbf{scor2prt}, then to ensure that the volte are properly
         transferred to the parts, you must only include one volta
         symbol \texttt{V} in each input block, and it must come at the
         beginning of the block.
   \item If a score ends while a volta is still open, {\PMX} will close
         it with a box.
\end{itemize}

\bigskip
Examples of volta usage can be seen in Fig.~\ref{fig:volta}.

\subsection{Meter Changes}   \label{sec:meterchg}
_{meter!change}  _{polyrhythmic scores}

The meter of a piece can only be changed at the beginning of an input
block, and thus naturally only at the beginning of a new bar, just
before the beginning of the first (lowest) voice of the first (lowest)
staff. As with the initial meter specified in the preamble, any new
meter applies to all instruments and voices\,%
\footnote{As was pointed out before (cf.~p.\pageref{p:polyrhythms}),
          this limits the use of {\PMX} for modern polyrhythmic music.
          But you can always try to play with tricks \dots
         }.

A \texttt{m}eter change symbol starts with the letter \texttt{m}. There
are two different ways to complete the symbol:
\begin{itemize}
   \item enter the 4 meter-defining numbers \texttt{mtrnuml},
         \texttt{mtrdenl}, \texttt{mtrnump}, \texttt{mtrdenp} for the
         new meter\,%
         \footnote{For the meaning of these numbers
                   cf.~p.\pageref{p:meterdefs} .
                  },
         \emph{separated by slashes} \texttt{/} .
   \item same as above, but enter the 4 numbers consecutively
         \emph{without spaces}. In this case, it is necessary to
         distinguish between one single 2-digit number and two
         consecutive 1-digit numbers. For this -- and for this case only
         -- the following convention is adopted:

         \vspace{-1.5ex}\noindent
         \begin{itemize}
           \item the number 1 is represented by the letter \texttt{o},
           \item consecutive digits \texttt{10},\dots \texttt{19} stand
                 for exactly that: the 2-digit numbers 10 through 19.
         \end{itemize}

         \vspace{-1.5ex}\noindent
         Thus, 19 is the largest number that can be entered with this
         method.
\end{itemize}
_{meter!blind change}
Note that \texttt{mtrdenl=0} still represents a whole note
(semibreve), as explained on p.\pageref{p:meterdefs0}, and a `blind'
meter is given by \texttt{mtrnump=mtrdenp=0}, as explained in
Table~\ref{tab:meter}.

\medskip  _{pickup bar}
The most common application of a `blind' meter change occurs when a
piece --- often one starting with a pickup --- has an incomplete final
bar. In such cases place the last bar in an input block by itself,
headed by a `blind' meter change. For example, if the meter had been 4/4
and there was a quarter note pickup, leaving 3 beats in the last bar,
the last bar might be coded \verb#m3400 cd24 of /#.

Another useful application is for the pickup bar in the second or later
movements, following a {\PMX} movement break symbol. Since there is
no special provision for pickups in this case like there is at the
beginning of a piece,   _{movement breaks}
\begin{enumerate}
   \item the pickup bar should be in a block by itself, starting with a
         meter change symbol with a logical meter representing the
         pickup bar and a printed meter as appropriate, and
   \item the next bar should start a new block and begin with a blind
         meter change symbol with a logical meter representing the true
         meter.
\end{enumerate}


\subsection{Key Changes} \label{sec:keychg}
_{key change}   _{K symbol@\texttt{K} symbol}

A key change can be signalled at any time\,%.
\footnote{Only one key change is allowed in each input block.
         }.
It must be entered in the first voice, but will affect all voices. Use
the command \texttt{K+0}, followed by the new key signature: positive
integer for sharps, negative for flats (cf.~Section~\ref{sec:numinput})
.

\medskip
Some examples are given in Fig.~\ref{fig:keychg}.

	\caption{Some transpositions of a d minor scale}
	\label{fig:transpose}
\end{figure}

To transpose an entire score to a different key from the one in which
the data have been entered, use the symbol \texttt{K} (for
\textbf{K}ey), followed by two explicitly signed digits: (1) the
distance to transpose by, in units of \verb#\internote# (i.e.\ the
vertical offset on the staff), and (2) the new key signature. This
symbol must be entered at the beginning of the piece, in the header
(cf.~p.\pageref{p:header}).

There is one case that requires special handling, viz., when transposing
by a half step, but the vertical position doesn't change, e.g.\ from D
flat to D. In this case the shift parameter (the first parameter of
\texttt{K}) is \emph{always} \texttt{-0} \emph{regardless} of whether
the transposition is up or down a half step\,%
\footnote{This artifact is needed to differentiate a half-note
          transposition from a mere key change  without
          transposition (cf.~Section~\ref{sec:keychg}) .
         };
the direction of the transposition will be determined by the new key
signature, the second parameter. An example is given in
Fig.~\ref{fig:transpose}.

\medskip
_{accidentals!relative}
When transposing, one should always use relative accidentals, activated
by the symbol \texttt{Ar} in the header (cf.~Section~\ref{sec:A} for a
detailed explanation of this notation).

Of course, if you have just one transposing instrument, or a choir of
same-type instruments, you can use the transposition mechanism effected
by the \texttt{K}ey symbol to easily obtain both the original score and
its actual sound. For an example of this use of the transposition
mechanism see Fig.~\ref{fig:tristan}.

_{wind instruments|see{instruments,transposing}}
\Note{The transposition of an an entire score must not be confused with
      the standard notation for `transposing' instruments, such as
      clarinets (in B, A etc.), oboe d'amore (which is in A), oboe da
      caccia (in F), or horns. {\PMX} does not provide a notation for
      this directly if transposing instruments appear together with
      non-transposing instruments in the same score, but it is easy to
      do it with some inline {\MusiXTeX}\,\footnotemark\
      (for details on this particular problem see the example of
      Mozart's \emph{Mauerische Trauermusik} in
      Section~\ref{sec:mtrauer}).

\subsection{Titles, and text above and below a system}
              \label{sec:titles} _{titles}
_{text!above/below system} _{T symbol@\texttt{T} symbol}

A \emph{title block} with up to three elements can be defined in the
header (cf.~p.\pageref{p:header}):
\begin{itemize}
\item \texttt{Ti}: an \textbf{i}nstrument name. It is set \emph{above}
                   the title, and left-justified,
\item \texttt{Tc}: the \textbf{c}omposer's name. It is set \emph{below}
                   the title and right-justified,
\item \texttt{Tt}: a \textbf{t}itle for the whole piece. It is centered
                   on the page.
\end{itemize}

Each of these commands is to be followed by a text string, \emph{on a
separate line}. This text must be fully contained in one line of {\PMX}
coding; but the text for the \textbf{t}itle can be spread out over
several lines in print by using the standard {\TeX} line break symbol
\verb#\\# .  _{\TeX!line break symbol}

\medskip
Extra vertical space can be added between the whole title block and the
top system by appending to \texttt{Tt} (without space) a one- or
two-digit number representing this space, in units of
\verb#\internote#\,%
\footnote{{\PMX} does this together with the adjustment of other
          vertical spaces when fixing the general page layout. In some
          rare cases, the result may not be quite what you expect, in
          particular when you haven't used the \texttt{Ae} option to
          equalize inter-system spacing
          (cf.~section~\ref{sec:options}). In such cases you might want
          to use inline {\TeX} --- take a look at the example in
          Section~\ref{sec:shiftname} for how this can be done.
         }.
This works only if \texttt{Tt} is the \emph{final} title block element
entered. Thus, although the 3 parts of a title block can be given in any
order, it is good practice to use the sequence \texttt{Ti} ---
\texttt{Tc} --- \texttt{Tt}.

_{titles!with \textbf{scor2prt}} _{\textbf{scor2prt}!use of Ti}
\Note{When you want to generate parts from a score with
      \textbf{scor2prt} (cf.~Section~\ref{sec:scor2prt}), you should
      \emph{omit} \texttt{Ti} with an associated \textbf{i}nstrument
      name, because each separate instrument usually has a different
      name. Rather, \textbf{scor2prt} will automatically supply the
      appropriate instrument names, printing the name of each instrument
      at the upper left of the first page of each part; the names used
      here are the ones specified in the preamble of the {\PMX} file for
      the score\,%
      {\footnotemark}.

      If you do have \texttt{Ti} together with an \textbf{i}nstrument
      name in the main score, \textbf{scor2prt} will print that name
      identically to all the parts --- which is usually not what you
      want!
     }
\footnotetext{\textbf{scor2prt} does this by inserting into the part
              \texttt{.pmx} file a \texttt{Ti} and the appropriate
              instrument name as taken from the preamble of the main
              score. Knowing this may be useful if you want to
              manipulate this process, e.g.~to change the vertical
              shifting of a particular instrument name
              (cf.~Section~\ref{sec:shiftname} for details).

\bigskip   _{h symbol@\texttt{h} symbol}  _{l symbol@\texttt{l} symbol}
The symbols \texttt{h} (for \textbf{h}eader)\,%
\footnote{This usage of the \textbf{h} symbol is not to be confused with
          that for the page size (see Section~\ref{sec:pagesize})!
          Although both can occur together in the header, they are in
          fact, different {\PMX} symbols, distinguished by their
          differing syntax.
         }
and  \texttt{l} (for \textbf{l}ower) can be used to introduce text
either above or below a system. These symbols must be placed in the
first column of an input line (not necessarily the beginning of a
block), and followed by a blank or -- for \texttt{h} only -- a signed
integer. In the latter case, this integer is a vertical shift, in units
of \verb#\internote#.

The text string, which again must lie on a line of its own immediately
following the symbol, will be printed above or below the \emph{top}
staff in the \emph{first} bar of the block where it is entered.
Figs.~\ref{fig:vivaldi1} and \ref{fig:Haydn} show examples.

\subsection{Page numbering and page headers}   \label{sec:pagenumbers}

\subsubsection{Page numbering}
_{page!numbering}   _{P symbol@\texttt{P} symbol}

By default, {\PMX} does \emph{not} number the pages of a score, even
when it has more than one page. You can, however, switch on page
numbering by using the symbol \texttt{P} (for \textbf{P}age). Placed at
the beginning of an input block anywhere within the {\PMX} body of
input, and followed optionally by a page number and/or by \texttt{l}
(for \textbf{l}eft) or \texttt{r} (for \textbf{r}ight), this will
\begin{enumerate}
   \item start page numbering at the current page\,%
         \footnote{The `current page' is the page where {\PMX} puts
                   the music currently processed at the point where it
                   encounters the symbol \texttt{P}.
                  }
         with the number given as optional argument. Further page
         numbers are then incremented automatically starting with this
         number. If \texttt{P} has no number argument, the default is
         page 1 . Thus, \texttt{P} and \texttt{P1} are equivalent),
   \item put the page numbers to the top \textbf{l}eft or \texttt{r}ight
         of the first of the pages to be numbered, after which the
         number positions will alternate. If no \textbf{l} or \textbf{r}
         is given, {\PMX} puts the page numbers on the right on
         odd-numbered pages, on the left of even pages.
\end{enumerate}
You can have as many \texttt{P} symbols in a score as you like; but
there is no command to switch off page numbering again once it has been
switched on.

\subsubsection{page headers}
_{page!headers}

There is one more option, \texttt{c} (for \textbf{c}entered header),
available with the \texttt{P} symbol. This option defines a text string
to be printed at the top of every page \emph{after the first}. The
notation is as follows:
\begin{itemize}
   \item The normal usage is \texttt{Pc"}$[$\emph{text
         string}$]$\verb#"#. The text string enclosed in the quotation
         marks must be a single line of text. It may contain blanks, but
         \emph{no} \verb#\\#). If the string consists of blanks only,
         that is what will be printed: a blank page header.
   \item If the text string does not contain any blanks, you may omit
         the quotation marks, but you must then start the text
         immediately after the \texttt{c} \emph{with no space}.
   \item If there is a blank after \texttt{Pc}, \emph{no quotation marks,
         and no further text}, the text printed as the header will be
         the instrument name entered with the symbol \texttt{Ti}, as
         described on p.\ref{sec:titles}.
\end{itemize}
\texttt{c} must be the \emph{last} option in the \texttt{P} symbol.

_{P symbol@\texttt{P} symbol} _{\textbf{scor2prt}}
\Note{The \texttt{P} symbol and all its options will be ignored when
      making parts from a score using \textbf{scor2prt}, since page
      numbering will usually be different in the score from that in the
      parts. Page numbering -- and centered headers -- for parts can,
      however, be initiated independently with another mechanism. For
      the details on this, refer to Section~\ref{sec:scor2prt}.

\subsection{Layout: line, page, and movement breaks}
    \label{sec:breaks}
_{layout} _{layout!manual line/page breaks}
_{\texttt{npages}} _{\texttt{nsystems}}

The parameters \verb#npages# and \verb#nsystems# of the preamble
(cf.~Section~\ref{sec:preamble}) determine the layout of the score,
either by fixing the total number of pages and systems, or by setting
the average number of bars per system. With no further instructions,
{\PMX} will attempt to distribute all the music evenly over the total
number of systems, and then spread the systems evenly over the specified
number of pages, either specified or determined by default (with
\verb#npages=0#).

You can change the average `crowdedness' by changing the preamble
parameters. Once this is satisfactory, you can exercise finer, more
local control by forcing, i.e.\ manually inserting, line or page breaks
at exactly the places you want them to be. You may also want movement
breaks, and {\PMX} has a convenient way of doing that, in the process
dealing easily with such `housecleaning' chores as indenting the first
system of the new movement, reprinting the time signature, resetting the
bar number counter, and other details to be discussed below.
_{bar numbering} _{indenting first system}

\medskip
It is worthwhile, however, to quote Leslie Lamport at this point:
_{Lamport, Leslie}
\begin{quote}
   ``Don't worry about line and page breaks until you prepare the
      absolutely final version'' \\
      From: Leslie Lamport, {\LaTeX}, \emph{user's Guide and Reference
      Manual} .
\end{quote}

This is especially true for a {\PMX}-generated score. Until the final
edit, you should always use \texttt{npages=0}. Once you specify any
forced line break, you can no longer use \texttt{npages=0}, and you will
have to specify values for \texttt{npages} \emph{and}
\texttt{nsystems}~. And because --- as we'll soon explain --- a movement
break is a sub-option of the linebreak command, you cannot set movement
breaks either until the final edit.

But unless your score is just a few pages long, you probably will want
to set some line, page, or movement breaks in the end. When you are
ready, always first pick some reasonable values for \texttt{npages} and
\texttt{nsystems}---perhaps the numbers that finally came out when you
used \texttt{npages=0} during the main input process. Then one way to
proceed is to start at the beginning, forcing breaks where desired. The
most common places would be at movement breaks, and at places associated
with volte or repeats. Recompile and view the result after each new
line break is inserted. You may need to adjust the total number of
systems or even pages depending on how crowded is the remainder of the
score, after the last forced line break.

The other way to proceed is to begin by inserting any obvious page
breaks, especially if you are laying out a booklet with facing pages and
want page turns to come in musically convenient places.

\bigskip\noindent
Here are the rules for inserting forced line, page, and movement breaks:
\begin{itemize}
\item _{line break}
      Line breaks can only come at the start of an input block. To force
      a line break at the start of the $n^\text{th}$ system, enter
      \texttt{L}$[n]$~. $n$ must obviously be greater than 1 and less
      than or equal to the value of \texttt{nsystems} as specified in
      the preamble.
\item _{page!breaks}
      Page breaks can only come where there is already a line break. To
      force a page break at the start of the $m^\text{th}$ page and the
      $n^\text{th}$ system, enter \texttt{L[}$n$\texttt{]P}$m$~. $m$
      must obviously be greater than 1 and less than or equal to the
      total number of pages.

\item _{movement breaks}
      Movement breaks can only come where there is already a line break.
      To force a movement break at the start of the $n^\text{th}$
      system, enter \texttt{L[}\emph{n}\texttt{]M}~. If in addition you
      want a page break at that point, use
      \texttt{L[}$n$\texttt{]P[}$m$\texttt{]M}~.

      \medskip
      The movement break symbol \texttt{M} has several optional
      parameters. They can be used in any combination and should follow
      with no spaces.

      \begin{itemize}
         \item \texttt{M+[}$k$\texttt{]} adds $k$ \verb#\internote#
               units of vertical space between movements. \item
               \texttt{Mi[}$.x$\texttt{]} resets the first-line
               indentation of the new movement to
               \texttt{fracindent=}\,$.x$~, where $.x$ is some
               decimal number (cf.~Sec. \ref{sec:preamble}).

               \Note{You must write the fracindent number exactly in
                     the form $.x$ , i.e.\ \emph{without} the leading
                     $0$~. If, e.g.\ , you write $0.2$ instead of
                     $.2$~, {\PMX} will complain with an error message,
                     asking for a decimal number!
                    }

         \item Beginning a new movement break, the bar number is reset
               to zero by default, whereas \\
               \texttt{Mc} \textbf{c}ontinues bar numbering.
         \item \texttt{M[}$n$\texttt{]} changes the \textbf{n}umber of
               instruments to $n$~. $n$ must not exceed \texttt{ninstr}
               as set in the preamble. If $n$ exceeds 9, it must be
               \emph{preceded} with \texttt{:} (colon). This should be
               followed (without blanks) by a sequence of $n$ instrument
               numbers in bottom-up order, again preceded with
               \texttt{:} if bigger than 9, then a sequence of clef
               symbols, one for each staff of each instrument starting
               from the bottom. An instrument's numeral is simply its
               position in the original sequence (in the preamble);
               these numerals can be permuted as desired, but the
               sequence of clef symbols should, of course, match the new
               sequence of instruments.
         \item \texttt{Mr+}/\texttt{Mr-} \textbf{r}eprints/suppresses
               reprinting the instrument names at the beginning of the
               new movement. The default is to print them only if the
               number of instruments changes.
      \end{itemize}
\end{itemize}

_{instruments!numbers increased/decreased}
It should be emphasized here that the number of instruments in a new
movement can never exceed the original number of instruments, although
it is permissible to increase it after it has been decreased, as long as
it doesn't exceed the original number; in other words, and to give an
example: a sequence {quartet --- solo --- duet, e.g.,  is possible,
while the reverse sequence is not. There are two ways to circumvent this
restriction:
\begin{enumerate}
\item  start the score with a dummy page --- to be discarded
       later --- containing the maximum number of instruments. On the
       second page, start a new movement with the desired number and
       sequence of instruments for the first movement,
\item  _{\PMX!concatenating several files}
       make separate {\PMX} files and concatenate them afterwards
       (cf.~Section~\ref{sec:concatfiles} or \ref{sec:LaTeX} on how to
       do this).
\end{enumerate}

\medskip
Immediately after a movement break, any desired meter changes, key
changes, or text can be entered as already described in
Sections \ref{sec:meterchg}, \ref{sec:keychg} and \ref{sec:titles}
(p.\pageref{sec:meterchg} ff.).

\bigskip
The effect of movement breaks is illustrated in the
example~\ref{sec:Dufay} in the appendix.

\subsection{Bar Numbering} \label{sec:barnumbers}
_{bar numbering} _{inline \TeX!bar numbering}

By default {\PMX} places a bar number above the first bar of the top
staff in every system, and there is no provision in {\PMX} to change
this default. But it is easy to change this by using a straight
{\MusiXTeX} command:
\begin{itemize}
   \item if you want no printed bar numbers at all, add a line in the
         header containing \\ \verb#\\nobarnumbers\#
   \item if you want bar numbers printed over every bar,  add a line
         containing \\ \verb#\\barnumbers\#
\end{itemize}
in the header or at the beginning of an input block.

This is an example of a \textbf{type 2} inline {\TeX} command,
cf.~Section~\ref{sec:inlineTeX}. As is explained there in detail, {\PMX}
will place a \textbf{type 2} inline {\TeX} command at the beginning of
the \verb#.tex# file produced, regardless of where in the \verb#.pmx#
file the command appears. This means that you cannot change this type of
bar numbering in mid-stream.

If you do want to change the bar numbering somewhere in the middle of a
score, use a \textbf{type 3} inline {\TeX} command: if, from the
current point in the score, you want
\begin{itemize}
   \item no printed bar numbers, add a line with \\
         \verb#\\\nobarnumbers\#
   \item bar numbers printed over every bar,  add \\
         \verb#\\\barnumbers\#
   \item bar numbers above the first bar of every system (the {\PMX}
         default), add \\ \verb#\\\systemnumbers\#
\end{itemize}
at the beginning of the current input block.

\medskip
_{Bar number count adjustment}
Furthermore, you might want to change the number itself. This occurs most
frequently when you have a pickup bar at the beginning of a repeat; some
-- including some commercial publishers -- do not include this pickup
bar in the number count, wheras {\PMX} does so by default. To adjust
this, use the \textbf{type 3} inline {\TeX} command
\verb#\\\advance\barno-1\relax\# .

\bigskip
{\MusiXTeX} provides still more elaborate bar numbering schemes, such as
a number over every $n^{\text{th}}$ bar. For details refer to the
{\MusiXTeX} manual.

\section{Some general options and technical adjustments}
         \label{sec:options}  _{\PMX!options!general}
         _{layout!general options}

\subsection{Global options}  \label{sec:A}
_{\PMX!options!global}_{A symbol@\texttt{A} symbol}

{\PMX} has many layout parameters with default settings. Some of these
can be changed by the user; for that purpose there are several symbols,
all beginning with \texttt{A}. Many of these are usually included in the
^{header}, but some may be entered at the beginning of any input block.
Table~\ref{tab:A} lists these options alphabetically; the following
subsections, grouped by types of settings, describe them in detail. When
using several of these commands, it is not necessary to enter them all
on separate lines; rather, you can concatenate them, in any order, with
just a single \texttt{A}, e.g.~\texttt{AdI2.3p+hlbr} .

\end{tabular}
\end{center}
         \caption{Symbols beginning with an \texttt{A} (global options)}
         \label{tab:A}
\end{table}

\subsubsection{Accidentals}
By default, big accidentals are used unless regular spacing doesn't
provide enough room. Thus the default behavior may cause a mixture
of big and small accidentals, and in fact is not recommended. Rather,
the user is advised to make his choice:
\begin{itemize}
  \item _{accidentals!big}
        \texttt{Ab} makes all accidentals \textbf{b}ig; this is
        usually preferred,
  \item _{accidentals!small}
        \texttt{As} makes all accidentals \textbf{s}mall.
\end{itemize}

\medskip   _{accidentals!absolute}
As was mentioned earlier (cf.~Section~\ref{sec:transpositions}), {\PMX}
by default uses the so-called `absolute' notation for inputting
accidentals, i.e.\ the notation explained in
Table~\ref{tab:noteparameters}.
In this notation, there is an obvious one-to-one correspondence between
accented characters in the {\PMX} source file (\texttt{s, f, n, ss, ff})
and the printed characters. This has a disadvantage, but it only
surfaces if you write the {\PMX} file in one key and later transpose it
using the \texttt{K} option described in
Section~\ref{sec:transpositions}. For example, suppose the original key
is F, with 1 $\flat$ in the signature, and you enter \texttt{bn}. Now if
you transpose to the key of C with \texttt{K-3+0}~, that note will be
printed explicitly as F natural, while it should be F sharp.

\medskip       _{accidentals!relative}  _{key signature}
The remedy for such problems is to use another notation, aptly named
`relative' accidental notation, used by some musicians and some
publishers in some countries. In this notation, a sharp, flat, or
natural sign denotes an alteration by a half-tone up, down, or none
\emph{relative to the note which would otherwise be indicated based
on the signature of the piece}. For example, in D~major, with 2
$\sharp$s in the signature, an F natural would be denoted not as
\texttt{fn} but rather as \texttt{ff}, while in d~minor, with one
$\flat$ in the signature, a B natural would be input not as
\texttt{bn} but rather as \texttt{bs}. Similarly, $\natural$s
accidentals refer to the notes prescribed by the signature; e.g., in
G~Major (1 $\sharp$ in the key) a \texttt{gn} sounds as a \emph{g},
while \texttt{fn} sounds as an F sharp.

\medskip     _{transposition}
For automatic transpositions to function properly, it is necessary
that the {\PMX} source for the score to be transposed use the
\emph{relative accidental notation}. This is effected by \texttt{Ar}
:
\begin{itemize}
  \item \texttt{Ar} directs {\PMX} to interpret accidentals
        in \textbf{r}\emph{elative} notation\,%
        \footnote{Note that this makes logical sense only if used in
                  the header, and accordingly there is no way to
                  `undo' this decision further down in a score.
                 }.
\end{itemize}

\subsubsection{Layout details}  _{layout}
When the note head of a dotted note is \emph{on} the line (e.g.\
for a \emph{g} in a violin clef), it is customary to place the
dot slightly \emph{above} the line. In staves with two voices,
there is an alternate custom, viz., to place the dot \emph{above}
the line in the \emph{upper} voice and \emph{below} the line in
the \emph{lower} voice. {\PMX}'s default is the first possiblity;
dots for both voices \emph{above} the line, but it can be
overridden:

\begin{itemize}
_{layout!dotted note in 2-voice staff}
_{notes!dotted note!dots in 2-voice staff}
_{voice!several voices in one staff}

   \item \texttt{Ad} causes the \textbf{d}ot -- for notes that are
         \emph{on} a line -- in the lower voice
         of any two-voice staff to be placed \emph{below} the
         line.
\end{itemize}

\noindent
By default {\PMX} inserts a horizontal gap of \verb#1\elemskip#
between a bar line and the first note in the bar. This can be
changed globally:
\begin{itemize}
  \item \texttt{Aa}$[x]$  sets the space before the first note in
        every bar to to $x$ units of \verb#\elemskip# .
\end{itemize}

\noindent
In {\PMX} it's not yet possible to specify a smaller font for selected
staves. But it can be done using an inline {\TeX} command (For details,
cf.~Section~\ref{sec:inlineTeX} and Section~\ref{sec:varstaves}). If you
do this, then you ought to use the \texttt{AS} option:

\begin{itemize}   _{staves!varying size}  _{\texttt{musicsize}}
   \item \texttt{AS}[\emph{ns}] . The additional sequence of
         \emph{ns} is mandatory here. It consists of exactly as
         many characters \texttt{-} (minus) or \texttt{0} (zero)
         as there  are staves in the score (\texttt{nstaves},
         cf.~Section~\ref{sec:preamble}): \texttt{0} if the font
         size of this staff is normal, \texttt{-} if it is
         small\,%
         \footnote{The sequence of staves is from bottom to top, as
                   described in the preamble. Cf.~p.\pageref{p:header}.
                  }.
         This tells {\PMX} to modify some horizontal spacing decisions
         to account for the smaller font size.
\end{itemize}

\subsubsection{Vertical spacing} _{spacing}  _{spacing!vertical}
\begin{enumerate}
  \item[a)] Spacing of staves within a system: \text{} \\
   If there is more than one staff in a system, {\PMX} computes the
   vertical spacing between the staves automatically. However, the
   algorithm isn't fully robust, and the result may not be pleasing.
   To change the spacing between the staves within a system, you can
   apply a scale factor $x$ to the default, either for the entire
   score, or for the current page only:
   \begin{itemize}
      \item \texttt{AI}$[x]$ multiplies the default
            \textbf{I}nterstaff spacing, \verb#\interstaff#, by the
            decimal number $x$ \emph{for the entire score}. This
            option should be placed in the header.
      \item \texttt{Ai}$[x]$ multiplies the default
            \textbf{i}nterstaff spacing by the
            decimal number $x$ \emph{for the current page only}.
            This option can be placed at the beginning of any input
            block (including the first), and overrides
            \texttt{AI}$[x]$ .
   \end{itemize}
   Note that if there is more than one system on a page, decreasing
   the interstaff spacing will increase the space between systems,
   and vice-versa.

  \item[b)] Spacing of systems on a page: \text{} \\
   {\MusiXTeX} normally draws a virtual box around each system and
   inserts equal vertical space between these boxes. When objects
   protrude above the top staff in a system -- such as the note
   \texttt{c46} in the violin clef -- or below the bottom one, this
   can lead to unequal spacing between the bottom staff line of one
   system and the top staff line of the next. You may prefer that
   this vertical spacing be constant for the whole page:
   \begin{itemize}
      \item \texttt{Ae} ensures that the spacing between the bottom
            staff line of one system and the top staff line of the
            next is constant for any one page\,%
            \footnote{It is generally advised to use the \texttt{Ae}
                      option by default, unless one has a specific
                      reason not to. When using this option, you may
                      Nevertheless, in certain cases you may want to
                      force more vertical space between certain systems.
                      There is a {\TeX} macro, called
                      _{\bs\texttt{spread}$[x]$}
                      \bs\texttt{spread}$[x]$, that can be inserted
                      anywhere in the system before the desired wider
                      gap. Its argument $x$ is the desired extra space,
                      in units of \bs\texttt{internote}
                      (cf.~Section~\ref{sec:inlineTeX}).
                      _{layout!\bs\texttt{spread}$[x]$}
                      _{\MusiXTeX!\bs\texttt{spread}$[x]$}
                     }.
   \end{itemize}

  \item[c)] Sparsely filled pages: \text{} \\
   Sometimes it may happen that a page contains just a few staves
   altogether, and then the white space between staves on such a
   page becomes excessive. In such cases -- specifically, if
   \verb#\interstaff# $>$ \verb#20\internote# -- {\PMX} will, instead
   of the equal spacing described above, group all systems near the
   top of the page. This can, however, be changed by the user:
   \begin{itemize}
      \item \texttt{Av} will suppress the grouping near the top,
            and ensure that systems will always be spread vertically
            regardless of how much white space is left between systems.
   \end{itemize}
   Note that \texttt{Av} acts as a toggle; the second time it is
   issued, the behavior will revert to the default.
  \item[d)] Vertical position of rests in 2-voice staves:
   \begin{itemize}
      \item \texttt{AK} activates special rules for vertical positioning
            of rests in two-voice staves.

            This general option is rather subtle; its explanation by Don
            Simons follows:
            \begin{quote}
             ``Without this option, rests in two-voice staves have
               default positions based on a simple rule that is not
               context-sensitive: those in the lower voice (the one
               before //\,) are 4 \verb#\internote# heights below their
               single-voice default positions, and those in the upper
               voice are 2 \verb#\internote# heights  above the
               single-voice default.

             ``The \texttt{AK} option invokes a set of context-sensitive
               _{rest!alignment in 2-voice staves}
               rules to set the default position. The baseline rule is
               to align the rest in a horizontal line with the next
               following note in the same bar. If there is no following
               note in the bar, then the rest is aligned with the last
               note before the rest.

               \medskip
             ``If there are simultaneous rests in both voices, the old
               rule is applied.

               \medskip
             ``The \texttt{AK} option is a toggle: it may be used at the
               start of any input block to turn these special rules on
               (if previously off) or off (if previously on).

               \medskip
             ``When the \texttt{AK} option is on, it only affects
               places where there are two voices in a staff.

               \medskip
             ``Any user-defined tweaks on the height of a rest will
               supersede the option for that particular rest, i.e.\ the
               tweak will be applied relative to the single-voice
               default position.''
            \end{quote}

            Sometimes you may want the rest to be aligned with the
            \emph{previous} note (the one \emph{to the left} of the
            rest), rather than the following note (the one to the right
            of the rest).

            This can be achieved simply by appending an \texttt{L} (for
            `\textbf{L}eft') to the rest symbol, i.e.\ by writing
            `\texttt{rL}' .
    \end{itemize}
\end{enumerate}

\subsubsection{PostScript type K slurs, ties and hairpins}
                                      \label{sec:usepsslurs}
_{PostScript!slurs, ties and hairpins}

The use of PostScript slurs, ties and hairpins circumvents most of the
shortcomings of the font-based counterparts. Of the two available
packages, only the type K slurs are explicitly supported by {\PMX}.
There is an option, \texttt{Ap}, to enable the use of this package.

\begin{itemize}
  \item \texttt{Ap} activate Type K PostScript slurs, ties and hairpins.

     \texttt{Ap} may also be entered at the beginning of any input block
     to activate certain suboptions controlling shapes and positions of
     the slurs and ties that are to be used. The first few of these
     options affect vertical positioning. When Type K PostScript slurs
     are activated with \texttt{Ap}~, slurs and ties will by default
     \emph{not} have their verticAl positions tweaked to avoid
     tangencies with staff lines.

     To control this type of adjustment, use one of the following
     suboptions to \texttt{Ap}~:
\begin{enumerate}
  \item
  \begin{itemize}
     \item \texttt{+s} activates automatic slur height adjustment,
     \item \texttt{+t} activates automatic tie height adjustment,
     \item \texttt{-s}/\texttt{-t} deactivate the corresponding
           height adjustment.
  \end{itemize}

  \item
    A second suboption, \texttt{+c}/\texttt{-c}, will increase or
    decrease the default curvature of the Type K slurs. The result of
    such commands is cumulative, and more than one suboption
    \texttt{+c} or \texttt{-c} may be used in a single command. If
    the cumulative change goes above \texttt{HH} or below
    \texttt{f}, a warning will be issued, the default will be set to
    \texttt{HH} or \texttt{f}, and processing will continue.

    Local curvature options in individual slur commands (cf.\
    Sec.~\ref{sec:usepsslurs}) will take precedence over the global
    default, but will \emph{not change the default}.
    \begin{quote}
      A special local option, \texttt{n} (`\textbf{n}ormal'), is of the
      `undo' type: it will cause that par\-ti\-cu\-lar slur, no matter
      what the global default happens to be, to have the normal
      curvature, i.e.\ between \texttt{f} and \texttt{h}.
    \end{quote}
  \item
  A third suboption, \texttt{l}, changes the appearance of slurs
     and ties that extend across line breaks:
  \begin{itemize}           _{slurs!across line break}
     \item Every slur/tie at a line break is automagically broken into
           two separate ones; no additional {\PMX} slur start or ending
           commands are required. Vertical and horizontal tweaks for
           the end of the first segment and Start of the second segment
           are entered as options in the normal command that starts the
           slur/tie:
           \begin{enumerate}
              \item the option for the end of segment 1 starts with
                    \texttt{s} (for \textbf{s}ever or \textbf{s}plit),
                    then the usual one or two signed numbers, then a
                    second \texttt{s} and one or two more signed numbers
                    for the start of segment 2,
              \item the usual curvature options \texttt{h, H, HH , f},
                    if included in the starting command for a line-break
                    slur, will apply to segment 1, and to segment 2 if
                    in the closing command. If the slur/tie does not
                    come at a line break, the special position tweaks
                    (those after the \texttt{s} option) will all be
                    ignored, and the curvature tweaks on the closing
                    note take precedence.
           \end{enumerate}
\end{itemize}
\end{enumerate}

         _{global options|see{\PMX!options!global}}
         _{general options|see{\PMX!options!general}}
         The \texttt{l} option can also be invoked globally
         (i.e.\ for the entire score) by specifying \texttt{Apl},
         instead of only \texttt{Ap}, in the header
         (recommended).
\end{itemize}

The third suboption concerns only line-break ties (it does not
affect slurs):
\begin{itemize}
   \item \texttt{+h}/\texttt{-h} activates/deactivates the use
         of special \textbf{h}alf-ties for the second segment of
         line-break ties after the line break. These are
         horizontal at their left end, and are only used if the
         required segment is shorter than 15 pt.
\end{itemize}
Note that this option is somewhat incompatible with the
\texttt{l} option, and they should not be used simultaneously.



\subsection{Page Size} \label{sec:pagesize} \label{p:pagesize}
        _{page!size} _{h symbol@\texttt{h} symbol}
                     _{W symbol@\texttt{W} symbol}
The default page size\,%
\footnote{This means the \emph{extent of the print} on the page. The
          -- empty -- top, bottom, left and right margins depend on the
          paper/printer used; they can not be altered within {\PMX}.
         }
is 740\,pt $\times$ 524\,pt (10.3\," $\times$ 7.3\,", or 261\,mm
$\times$ 185\,mm). To change the height or width, use the special
symbols \texttt{h}[\emph{n}][\emph{u}] or \texttt{w}[\emph{n}][\emph{u}]
in the header.  Here \emph{n} is a decimal number for the new size, and
\emph{u} defines the units: \texttt{i} for inches. \texttt{m} for
millimeters, and \texttt{p} for points. if no unit name \emph{u} is
given, \PMX} uses points as the default.

This command can be used together with \texttt{\%\%} or \texttt{\%!}
(see Section~\ref{sec:scor2prt}) to give the parts made by
\textbf{scor2prt} different page sizes than the parent score.

\medskip
\Note{This usage of the \textbf{h} symbol is not to be confused with
      that for a line of text above a system (see
      Section~\ref{sec:titles})! Although both can occur together in the
      header, they are in fact, different {\PMX} symbols, distinguished
      by their differing syntax.
     }

\subsection{Stem direction of bass notes} \label{sec:stemdirs}
               _{stems!direction of bass notes}  _{B symbol@\texttt{B} symbol}
By default {\PMX} makes stems go \emph{up} for middle-line D's in bass
clef, but \emph{down} for notes on the middle line of all other clefs.
If you want middle-line bass-clef notes also to have downward stems by
default, enter the symbol \texttt{B} in the header.

\subsection{Horizontal Spacing}  \label{sec:spacing}
     _{spacing!horizontal}

\subsection*{Minimum Spacing between Notes}

_{W symbol@\texttt{W} symbol} _{spacing!minimum between notes}
{\PMX} does some special, complex analysis to adjust horizontal spacing
in crowded systems. By default, the minimum space between consecutive
noteheads is 0.3 notehead widths. If you want to change this value to
some other fraction, enter \texttt{W.}$[n]$, where $n$ is a single digit
between \texttt{1} and \texttt{9}, giving the minimum spacing, in tenths
of a notehead width. This adjustment is very rarely used.

\subsubsection*{Extra Horizontal Shifts and hardspace}
     _{spacing!hard space} _{hard space|see{spacing}}

{\PMX} will usually provide satisfactory horizontal spacing. However,
there may be some occasions where you will want to adjust it manually. A
symbol starting with {\tt X} controls one of two available types of
horizontal adjustment:
\begin{enumerate}
  \item a \emph{shift} moves one or more characters in the current voice
        but does not affect any other spacing anywhere,
  \item a \emph{hardspace}, by contrast, is a fixed amount of space
        inserted at a particular time. The horizontal positions of
        everything in all staves in the system will be adjusted to
        accommodate the added space while maintaining vertical
        alignment.
\end{enumerate}
Here are the syntactic possibilities:
\begin{itemize} _{X symbol}
   \item \texttt{XS}$[x]$ (for \textbf{S}hift). This command shifts the
         the next character; $x$ is a decimal number, giving the amount
         of shift, in units of a notehead width.
   \item \texttt{X:[}$x$\texttt{]} or \texttt{X[}$x$\texttt{]:}
         initiates a ``group shift'', which operates like
         \texttt{XS[}$x$\texttt{]}, except that everything from the
         insertion point onward in the current voice is shifted until a
         termination symbol (``shift end'') is encountered.
   \item \texttt{X:} ends a ``group shift''.
   \item \texttt{X}$[x]$ (without any \texttt{S} or \texttt{:}) is a
         so-called \emph{hard space}. It inserts the specified space,
         given in units of notehead widths, at the present point in
         \emph{all staves} of the system. If $x$ is negative, space will
         be removed.
\end{itemize}

_{X symbol!with \textbf{scor2prt}}
Because horizontal spacing in parts will usually differ from that in the
score, \textbf{scor2prt} (cf.~Section~\ref{sec:scor2prt}) will by default
copy \emph{only} the shift commands \texttt{XS}$[x]$, \texttt{X:}$[x]$
and \texttt{X:} into the parts, but \emph{not} the hardspace command
\texttt{X}$[x]$ .


\medskip
This behavior can be overridden using the methods described in
section~\ref{sec:scor2prt}. There is, however, an alternative method that
helps to keep {\PMX} score files neat and readable: add the suboption
\texttt{B} or \texttt{P} (without space, as usual) to the \texttt{X}
symbol:
\begin{itemize}
   \item \texttt{B} (for \textbf{B}oth): with this option, the spacing
         symbol is to be applied to \textbf{b}oth score and part,
   \item \texttt{P} (for \textbf{P}art): with this option, the spacing
         symbol is to be applied to the \textbf{p}arts only.
\end{itemize}

\section{Macros}  \label{sec:macros} _{\PMX!macros} _{M symbol@\texttt{M} symbol}

A {\PMX} macro is a single symbol that stands literally for any
any string of characters that may occur in the input file\,%
\footnote{Note to seasoned programmers: {\PMX} macros are not really
          macros in the usual sense, but merely string abbreviations;
          they \emph{do not allow} for variables.
          _{\PMX!macros!no variables}
         }.
Macros may be useful to save tedious typing and disk space, and make
{\PMX} source text more readable if you need to repeat the same string
many times in a score.

\medskip
You may define up to 20 macros in any single {\PMX} input file. There is
no practical limit to the length of the character string that a
macro represents, but of course it must respect the {\PMX} rules on the
length of input lines and what must go on separate lines.

\medskip
Macros only exist within the {\PMX} input file where they are defined;
you can define a completely new set of macros in another {\PMX} input
file. Conversely, if you want to re-use the macros of file
\texttt{myopus1.pmx} in \texttt{myopus2.pmx}, you need to copy them
explicitly from one file to the other.

\medskip
There are two distinct ways to define and record a new macro or
redefine an existing one:

\begin{enumerate}
   \item to \textbf{R}\emph{ecord} a \textbf{M}acro: type
         \texttt{MR}$[n]$, followed by a space, as usual. $n$, the
         ``name'' of the macro, is an integer between 1 and 20.
         Everything you type after this will be processed normally, at
         that point in the input file, as well as stored, until you end
         the macro by entering the symbol \texttt{M},
   \item to \textbf{S}\emph{ave} a \textbf{M}acro: type
         \texttt{MS}$[n]$. Everything you type after this will be
         recorded (saved) as you enter it, \emph{without processing}
         the {\PMX} code. When saving macros, it is usually best to put
         them in the header, for readability's sake.
\end{enumerate}

Whenever you would otherwise need to re-enter the same character string,
you can simply \texttt{P}lay back the macro by typing \texttt{MP}$[n]$~.

\medskip
Macros can be redefined at will; {\PMX} will issue a warning whenever
this occurs.

\bigskip  _{\textbf{scor2prt}!macros} When you use
macros and want to make separate parts
(cf.~Section~\ref{sec:scor2prt}), some care is necessary:
\textbf{scor2prt} will transfer a \texttt{MR} macro only into the part
where it originated, but will transfer \texttt{MS} macros into all
parts.

\medskip
So if you want to make macro 1, which you will use in several or all
parts and then use it immediately in the part in which you write it,
dont use simply \verb#MR1#, but rather
\begin {verbatim}
              MS1
              MP1
\end{verbatim}

\section{Inline {\TeX} commands}    \label{sec:inlineTeX}
      _{inline \TeX}

It may be worthwhile to reiterate at this point the very different
intentions of the software ingredients which make up the {\PMX} tool. It
is, in fact, a hierarchy:
\begin{enumerate}
   \item       _{\TeX}  _{Knuth, Donald E.}
         At the base of it all is {\TeX}. {\TeX} (written by Donald
         E.\ Knuth) is a general and extremely powerful tool for
         typesetting high-quality documents on a computer that are ready
         for printing\,%
         \footnote{``Its emphasis is on art and technology, as in the
                   underlying Greek word.'' (quote from the introduction
                   of \emph{the {\TeX}book}, the authoritative book on
                   {\TeX}, by Donald E.\ Knuth. _{Knuth, Donald E.}
                  }.
         But {\TeX} is much more than that: it is a full-grown and
         powerful computer programming language with which -- if you are
         a {\TeX}pert -- you can do almost anything.

         \medskip
         There is, however, a price to pay for this power: while you
         don't have to be a professional computer programmer to use
         {\TeX}, a pretty good familiarity with the basics of
         programming is unavoidable.
   \item            _{\MusiXTeX}  _{Taupin, Daniel}
         {\MusiXTeX} (written essentially by Daniel Taupin) is a
         `macro' for {\TeX}\,%
         \footnote{To be precise, {\MusiXTeX} consists of a very
                   extensive set of {\TeX} `macros' and music
                   typesetting fonts.
                  }.
         That alleviates most of the {\TeX} programming tasks for the
         special purpose of typesetting music. Thus, while it helps to
         have a programming background, such a background is not
         absolutely essentially for someone who just wants to write a
         few simple music scores.
   \item           _{\PMX} _{Simons, Don}
         {\PMX}, the `preprocessor' for {\MusiXTeX} written by Don
         Simons and described in detail in this tutorial, is yet another
         level of abstraction on the long way from the musical ideas
         that make up a score to getting ink on the paper at certain
         points. The whole purpose of {\PMX} is to make typesetting of
         music with {\MusiXTeX}/{\TeX} accessible to people with
         essentially \emph{no} prowess in computer programming.
\end{enumerate}
As a consequence of this hierarchy, {\PMX} is vastly simpler to use than
{\MusiXTeX}, which in turn is simpler than straight {\TeX}. But the
converse of this is also true: there are elements in {\MusiXTeX} that
are not directly accessible with the {\PMX} language, just as you cannot
unleash the full power of {\TeX} with {\MusiXTeX} alone.
So to allow the user full access to `lower-level' {\MusiXTeX} or {\TeX} --
while maintaining its higher-level notational simplicity -- {\PMX}
supports the inclusion of {\TeX} commands either directly in the
{\PMX} input file or via an external file.

\subsection{Including {\TeX} Commands in the \texttt{.pmx} source file}
            _{inline \TeX!in \texttt{.pmx} source}
The normal way for a {\PMX} user to insert user-defined {\TeX} code is
to enter it directly in the \texttt{.pmx} input file; this is what is
referred to as ``\,inline {\TeX}\,'' in this tutorial. There are four ways
to do that; these differ mainly in where the {\TeX} code will appear in
the {\PMX} output \texttt{.tex} file. The first 3 of these have \bs\ ,
\bs\bs\ or \bs\bs\bs\ (1, 2 or 3 backslashes) as a starting symbol, then
comes a sequence of {\TeX} commands, then another \bs\ (backslash) as a
terminating symbol, followed by the usual space\,%
\footnote{This means that type 1, 2, and 3 {\TeX} strings may \emph{not}
          contain the \TeX\ macro `\bs\,\,\,' \,(backslash-space). If
          you really need that, replace it by \bs\texttt{relax }.
         }.
All three of these must be contained fully in \emph{one line of input},
limited by default to 128 characters (cf.~Section~\ref{sec:limits}); but
this one line can contain any number of concatenated {\TeX} commands.

\medskip
The above description needs clarification on a subtle point: the
starting symbols \bs\ , \bs\bs\ or \bs\bs\bs\ \, are \emph{not} really
{\PMX} symbols in the sense used throughout this tutorial, in that there
would be `white space' after them, but the {\TeX} command(s) follow them
\emph{without a blank}. This has to do with the fact that all {\TeX}
commands -- called `control sequences' -- start out with a \bs\ . And
thus the last of the starting backslashes (the only one for type 1,
the second one for type 2, the third one for type 3) counts as the
{\TeX} control character of the following {\TeX} command. For example,
if you wanted to define a new {\TeX} command \verb#\Myspace# as a type 1
inline command, you would write
\begin{center} \verb#\def\Myspace\hskip{10mm}\ # \end{center}
whereas if it is to be a type 3 inline command, it would read
\begin{center} \verb#\\\def\Myspace\hskip{10mm}\ # \end{center}
in other words: the starting symbol itself also provides the first \bs\
of the {\TeX} command (control sequence).

This convention can also be seen clearly in the examples given below.

\bigskip
Here are the characteristics of the first three types:
\begin{description}   _{inline \TeX!Type 1/2/3/4}
   \item[Type 1 ( \bs\ \dots \bs\ ) : ]
        a Type 1 string usually serves to define or execute a command
        that is only needed locally for the current line of music, right
        after the place where it is entered in the \texttt{.pmx} file.
        {\PMX} inserts it in the resulting \texttt{.tex} file right
        before the {\MusiXTeX} command for the next note or rest.
        Multiple type 1 strings associated with the same note or rest
        are allowed, although the total length may not exceed 128
        characters. So there is generally no reason not to combine all
        {\TeX} commands for a single note into a single type 1 string.

        \Note{If an inline {\TeX} string contains a new {\TeX}
              definition, this definition is in general \emph{not}
              local; depending on circumstances, it can remain valid
              throughout the score and for \emph{all instruments} unless
              redefined somewhere\,! This is true for all types of
              inline {\TeX}, Type 3 in particular. So be careful!
             }
   \item[Type 2 ( \bs\bs\ \dots \bs\ ) : ] a Type 2 string usually serves
        to define or execute a command that is needed throughout the
        entire score. It will appear near the top of the \texttt{.tex}
        file, right before the \bs\texttt{startmuflex}, regardless of
        where it appears in the \texttt{.pmx} file.
   \item[Type 3 ( \bs\bs\bs\ \dots \bs\ ) : ] Type 3 strings will appear
        in the \texttt{.tex} file right before the \bs\texttt{xbar} or
        \bs\texttt{alaligne} of the current input block, i.e.\ before
        its first bar line. Thus a Type 3 string is typically used when
        you want to redefine a previously defined {\TeX} command, to be
        valid from a certain point on, but not before.
   \item[Type 4 : ]   \label{sec:inlinetypefour}
        The fourth way of inserting inline {\TeX} in a \texttt{.pmx}
        file is different from the first three in several ways:
        \begin{itemize}
           \item it is started by the character sequence \verb#---#
                 (triple dashes), on a line by itself, as the very first
                 line of the \texttt{.pmx} file,
           \item it is terminated by the next appearance of the same
                 character sequence, \verb#---# (triple dashes), on a
                 separate line,
           \item it can contain any number of lines with {\TeX} code,
                 although every single of these lines is again
                 restricted to a total of 128 characters,
           \item the lines of {\TeX} code between the opening and
                 terminating triple dashes will be copied
                 \emph{literally} to the very top of the \texttt{.tex}
                 file.
        \end{itemize}
        So Type 4 can also be (ab)used to copy comment lines
        literally from the \texttt{.pmx} file to the \texttt{.tex} file.
        This is convenient for documentation purposes.
\end{description}

\medskip _{inline \TeX!handled by \textbf{scor2prt}}
Another difference of practical importance is the way in which
\textbf{scor2prt} handles these type of inline {\TeX} when making
separate parts (cf.~Section~\ref{sec:scor2prt}): types 2-4 will be
copied into all parts, while type 1 only goes into the part in which it
appears in the original \texttt{.pmx} file.

\bigskip\bigskip
To understand better the differences between these 4 types on inline
{\TeX}, it may be useful to study the basic structure of the {\TeX} file
\texttt{inlinesample.tex}, given in Table~\ref{tab:inlinesample.tex},
produced from the {\PMX} input file \texttt{inlinesample.pmx}, given in
Fig.~\ref{fig:inlinesample.pmx}. In doing so, you may want to look at
the box on p.~\pageref{p:inlinesample.txt}.

\begin{table}[!ht]
\begin{center}       _{inline \TeX!placement in \texttt{.tex} file}
\fbox{
\begin{minipage}{350pt}
Here is a short survey of what happens in the file
\texttt{inlinesample.tex} (cf.~Table~\ref{tab:inlinesample.tex}),
produced from \texttt{inlinesample.pmx}
(cf.~Fig.~\ref{fig:inlinesample.pmx}):

\begin{itemize}
   \item first, after the file name comment, which is inserted
         automatically by _{\textbf{pmxab}} \textbf{pmxab}, the Type 4
         string (the comment line on the top of the \texttt{.pmx} file)
         is inserted [line 6],
   \item then the files \texttt{musixtex.tex, pmx.tex} and
         \texttt{musicmad.tex} are always read in [lines [7,8,9]. This
         means that the \texttt{.tex} that {\PMX} produces has
         \emph{access to all the {\TeX} macros} defined in these files,
         and therefore you can use all of these in your inline {\TeX}
         commands,
   \item next, up to and including \bs\texttt{nostartrule} [line 23],
         there are a lot of settings, the details of which need not
         concern us here,

         \medskip
        The following {\TeX} macro [line 24],
        \bs\texttt{readmod{sample}} , tells {\TeX} to read in the file
        \texttt{inlinesample.mod} (if it exists). The file
        \texttt{inlinesample.mod} may contain any valid {\TeX} code of
        your choosing (cf.~Section~\ref{sec:external} for details on
        this),
   \item next [line 25] is the Type 2 string
         ``\bs\bs\texttt{nobarnumbers}\bs''. Type 2 strings are
         \emph{always} inserted at this point of the \texttt{.tex} file,
   \item \bs\texttt{startmuflex} [line 26] -- never mind what exactly it
         does -- is the actual beginning of the musical code,
   \item several lines down [line 31] there is an item
         \bs\texttt{hu g} : this is the half-note $g$ of the first
         bar,
   \item [line 32] contains the Type 3 string
         ``\bs\texttt{systemnumbers}\bs''. This changes the bar
         numbering scheme to the {\PMX} default
         (cf.~Section~\ref{sec:barnumbers}). {\PMX} inserted this Type
         3 string right before the next \bs\texttt{alaligne} [line 34],
   \item [line 35] contains the Type 1 string
         ``\bs\texttt{zcharnote{-2}}\bs\texttt{PED}\bs'', which prints
         the {\MusiXTeX} pedal\,%
         \footnote{The `end of pedal' symbol \bs\texttt{DEP} is coded
                   here in an alternative (perhaps simpler) way by using
                   a {\PMX} dynamics textual symbol

                   _{dynamic marks!textual}
                  },
   \item [line 37] contains another Type 3 string
         ``\bs\texttt{barnumbers}\bs'', before the code for bar 3 ,
         inserted right before \bs\texttt{xbar} in line 39 (coding the
         bar line). This changes the bar numbering scheme once again.

\subsection{Denoting pitch in inline {\TeX} }
_{inline \TeX!pitch given as a number}
_{pitch!in inline \TeX!}

When using inline {\TeX}, you should be aware of a subtle aspect, which
can be a hazard:

\smallskip
In {\MusiXTeX}, you can always refer to a pitch with a number, rather
than a letter, and that number denotes exactly the position on whatever
staff you are using, counting from the bottom line as $0$ .

When you use this for a pitch, it will not be transposable, nor will it
respect (or indeed affect!) the memory \PMX\ keeps on the pitch: remember
that {\PMX} doesn't interpret any inline {\TeX} .

You should keep this in mind when designating a pitch within an inline
{\TeX} command.

\bigskip\noindent
We close this section with two practical examples and a final remark:
\begin{itemize}
   \item  _{\textbf{musixpss}}
         As was stated in Section~\ref{p:useMslurs}, when using Type
         M slurs you need to insert the line
         \begin{center}
            \bs\bs\texttt{input~musixpss{\bs}relax}\bs\
         \end{center}
         into the header of the \texttt{.pmx} file. This tells {\PMX} to
         read in the file \texttt{musixpss.tex}, which contains the
         macros for Type M slurs.

         \medskip
         This is the case of a type 2 inline {\TeX} string, and thus
         the input command is added to the \texttt{.tex} file right
         before \bs\texttt{startmuflex} (which is where it belongs).
   \item _{clefs!exotic} _{clefs!octave clefs} _{clefs!symbols}
         _{clefs!empty} _{octaviation!of clefs}
         Sometimes one needs clefs other than those defined in {\PMX}
         (cf.~Section~\ref{sec:numinput}). Some special clef symbols
         (among them no clef at all) are defined in {\MusiXTeX} and can
         be invoked by the command \bs\texttt{setclefsymbol} (cf.~the
         {\MusiXTeX} manual, Sec.~2.21.2). The most common of these are
         octave treble and octave bass clefs, in which a small $8$ is
         attached to either the top or the bottom of the clef symbol. To
         get a higher octave treble key for instrument number $2$, for
         example\,%
         \footnote{Matters are more complicated for instruments with
                   more than 1 staff, such as piano or organ, because
                   the number in the command refers to the number of the
                   \emph{instrument}, not the staff. Cf.~the
                   {\MusiXTeX} manual, Sec.~2.27.10 for details.
                   },
         just add the following type 2 inline {\MusiXTeX} command
         \begin{center}
           \bs\bs\texttt{setclefsymbol}\{\texttt{2}\}
           \qquad \bs\texttt{trebleoct}\bs \qquad.
         \end{center}
         The other 3 octave clef symbols are \bs\texttt{treblelowoct},
         \bs\texttt{bassoct},\bs\texttt{basslowoct}, for lower octave
         treble, higher octave bass and lower octave bass clefs, resp.

\end{itemize}
More examples can be seen in Section~\ref{sec:tricks} and in some of the
scores of the appendix.

{\PMX} provides one further option for entering an unlimited set of
{\TeX} commands, read into the {.tex} file by \verb#\readmod# just
before the \bs\texttt{startmuflex} line. command, and before any Type 2
inline {\TeX} strings. Simply put the commands into a text file named
[\emph{filename}]\texttt{.mod} in the current directory\,%
\footnote{This feature is retained mainly for backward compatibility
          with previous versions of {\PMX}; it has now been essentially
          replaced by the 4 options for inline {\TeX} strings described
          above.

\section{Making Parts from a Score}
     \label{sec:scor2prt}  \label{p:scor2prt} _{\textbf{scor2prt}}

Separate parts can be made from a score with the tool \textbf{scor2prt}
(included in the standard {\PMX} distribution). Suppose you want to
produce the parts to the ``Mauerische Trauermusik''
(Fig.~\ref{fig:mtrauermus}), and the \texttt{.pmx} file of that score is
called \verb#mtrauermus.pmx#. All you to need to do is to run
\begin{center}\begin{verbatim}
        scor2prt mtrauermus
\end{verbatim}\end{center}
from the command line (if you omit the file name, you will be prompted
for one). The program will then create the following \texttt{.pmx}
files, one for each instrument\,%
\footnote{As is explained in Section~\ref{sec:mtrauer}, this particular
          {\PMX} source has defined both the oboes and the violins as
          one two-staves instrument each, so that there is a total of
          only 8 `instruments'.
         }:

\medskip
\hspace*{2.5em}
\begin{minipage}{20em} %
  \texttt{mtrauermus1.pmx} \qquad [\,Violoncello\,]                  \\
  \texttt{mtrauermus2.pmx} \qquad [\,Viola\,]                        \\
  \texttt{mtrauermus3.pmx} \qquad [\,Violins\,]                      \\
  \texttt{mtrauermus4.pmx} \qquad [\,French Horn II, in C\,]         \\
  \texttt{mtrauermus5.pmx} \qquad [\,French Horn I, in E $\flat$\,]  \\
  \texttt{mtrauermus6.pmx} \qquad [\,Basset Horn I, in F\,]          \\
  \texttt{mtrauermus7.pmx} \qquad [\,Clarinet in F\,]                \\
  \texttt{mtrauermus8.pmx} \qquad [\,Oboes\,]
\end{minipage}

\medskip
To obtain the parts, you then need to run each of these files through
{\PMX}, in the usual way.

As can be seen in the example, the parts files will be named
[\emph{yourscorename}][\emph{n}]\texttt{.pmx}, where [\emph{n}] is the
number of the instrument, by default; but the names of the files
created by \textbf{scor2prt} can be changed from within the {\PMX} file
for the whole score, the ``parent file''. For example, to cause the
file for instrument 3 to be named \texttt{mviolins.pmx}, include the
command \texttt{AN3"mviolins"} in the header of the parent file
(cf.~Table~\ref{tab:A}).

\bigskip
In the remainder of this section we describe how to control the layout
of the parts separately from that of the score by using commands that
are placed in the parent file.  This eliminates the need for editing the
\texttt{.pmx} files for the parts separately.  You can accomplish all
the editing in the parent file, and then re-run \textbf{scor2prt} as
required. Thus both the score and the parts can be corrected together,
and the parts need not be re-edited each time they are re-generated from
the score.

\subsection{Usage}
_{\textbf{scor2prt}!usage} _{comments!usage with \textbf{scor2prt}}

Since comment lines are by definition disregarded by {\TeX} and by the
{\PMX} program itself (\textbf{pmxab}, to be exact), they can, with a
slight extension of their syntax, be used to transfer information
\emph{meant for the parts only}\,%
\footnote{This is quite a useful method, employed in a similar way by
          other programs, such as the PostScript language.
          _{PostScript}
         }.
The following rules are used for this by the \verb#scor2prt# program:
\begin{itemize}
   \item If a line has \texttt{\%} in columns 1 and a space in column 2,
         it is considered a regular comment and transferred as such to
         all parts.
   \item If a line has \texttt{\%\%} in columns 1-2, both it \emph{and
         the following line} will be ignored when making parts.  If the
         ignored line (the second line) has \texttt{h}, \texttt{l}, or
         \texttt{T} in its first column, then \emph{one additional line}
         will be ignored (cf.~\ref{sec:titles} for the rationale behind
         this rule).
   \item If a line has \texttt{\%!} in columns 1-2, these first 2
         characters will be stripped, and the rest of the line will be
         put in the \texttt{.pmx} files for \emph{all} the parts.
   \item If a line has \texttt{\%}[\emph{h}] in columns 1-2, where
         \emph{h} is the hexadecimal digit representing the instrument
         number (\texttt{1, 2,..., 9, a, b, c}), the first two
         characters will be stripped and the rest of the line
         transferred to the part for instrument \emph{h} \emph{only} .

         \smallskip
         A good example for this usage is the page break(s) in a longer
         score, where the appropriate page numbers for the parts will be
         different from those in the full score.
         For example, to force a line break to system 15 and a page
         break to page 2 in \emph{part 11 only}, enter
         \texttt{\%bL15P2}.

             _{\textbf{scor2prt}!HEX digit usage incompatible with
                                 previous {\PMX} versions}

         \Note{The use of the hexadecimal digits \texttt{a-c} in this
               rule creates a potential incompatibility with previous
               versions of {\PMX}. To minimize this, the character after
               ``{\tt\%}" will \emph{only} be interpreted as a part
               number if it represents a number less than or equal
               \texttt{noinst}, as given in the parent file; otherwise
               the entire line will be treated as an ordinary comment,
               and transferred to all parts.
              }

   \item In addition to all entries in the header except \texttt{I}
         options (cf.\ Sec.~\ref{sec:MIDI}, p.~\pageref{sec:MIDI}), the
         following {\PMX} symbols \emph{with all their options} will
         automatically be copied to \emph{all parts} (unless the
         previous line starts with \texttt{\%\%}, of course):

         \begin{center}\begin{tabular}{l@{\qquad}l} \texttt{R}    & (bar
            symbol) \\ \texttt{V}    & (volta) \\ \texttt{K}    & (key
            change or transposition) \\ \texttt{A}    & (global options)
            \\ \end{tabular}\end{center} This is true for
            \texttt{R,V,K}, in spite of the fact that they can be
            entered in the \emph{first} voice of the score only!
            \end{itemize}

\subsection{The \texttt{S} symbol}   \label{sec:Ssymbol}
            _{S symbol@\texttt{S} symbol}

\begin{itemize}
   \item \texttt{S}[\emph{n}]:

         By default the total number of systems in each part will be the
         same as in the score.  If you want to override this, you can do
         that with \texttt{S}[\emph{n}], where \emph{n} is
         the desired number of systems. \texttt{S}[\emph{n}], if used,
         must appear in the header of the parent file. Legally, you
         could use \texttt{S}[\emph{n}] to reset the number of systems
         for the parent file itself, which you had just defined in the
         preamble. That, of course, does not make much sense, but in
         the form \\
         \text{\quad}\texttt{\%!S}[\emph{n}] \\
         or \\
         \text{\quad}\texttt{\%}[\emph{k}]\texttt{S}[\emph{n}] \\[1ex]
         it does, because then it does \emph{not} affect the full
         score, \emph{but all parts}, or part k only, resp. \\
         \texttt{barsant.pmx}, one of the examples given in Section
         \ref{sec:donsexamples}, includes a demonstration of this.
   \item \texttt{S}[\emph{n}]\texttt{P}[\emph{m}]:

         \textbf{scor2prt} will also compute how many pages it thinks
         each part should have, and enter that into the preamble for
         that part.  If you wish to override that, then insert into the
         parent file \texttt{\%3S14P2} for example, which would force
         the third part to have 14 systems and 2 pages. You cannot
         override the number of pages without first overriding the
         number of systems.

   \item \texttt{S}[\emph{n}]\texttt{m}[\emph{k}]:

         A musicsize of 20 is the default in all parts.  This may be
         overridden with the option \texttt{m} in the symbol \texttt{S}:
         e.g., \texttt{\%2S15m16}. Again, you must specify the number of
         systems before setting the musicsize.
\end{itemize}

\Note{Keep in mind the distinction among the various usages of
      \texttt{P}:
      \begin{itemize}
         \item as an option with \texttt{S}, it sets the total number of
               pages in a part,
         \item as an option with \texttt{L}, it forces a page break,
         \item as a {\PMX} command on its own, it controls page
               numbering and centered headings.
      \end{itemize}     _{P symbol@\texttt{P} symbol}
     }
\subsection{Other usage rules}
                   _{\textbf{scor2prt}!usage}
\begin{itemize}

   \item Inline {\TeX} strings of Type 2-4 will be copied to all parts,
         while a type 1 inline {\TeX} string will only go into the part
         in which it occurs in the parent file.
   \item _{spacing!hard space use with \textbf{scor2prt}}
         User-defined hardspaces (\texttt{X} without \texttt{:}) are by
         default not copied to parts. There are two ways to change this
         default: _{X symbol}
         \begin{enumerate}
            \item use the options of the \texttt{X} command
                  (cf.~Section~\ref{sec:spacing}): \texttt{B} causes
                  the hardspace to be used in \textbf{b}oth score and
                  parts; \texttt{P} puts it into the \textbf{p}arts, but
                  not the score,
            \item to insert \emph{x} notehead widths of hardspace into
                  part \emph{n}, place the symbol
                  {\tt\%}[\emph{n}]\texttt{X}[\emph{x}], on a line of
                  its own, in the parent file.
         \end{enumerate}
         _{page!numbering!with \textbf{scor2prt}}
         _{\textbf{scor2prt}! page numbering}
   \item As was already noted (cf.~Section~\ref{sec:pagenumbers}), a
         \texttt{P} symbol for page numbering in the parent file is
         ignored when making parts.  To initiate page numbering in the
         parts, use, for example, \texttt{\%!P} , with appropriate
         options added, anywhere within the {\PMX} code representing the
         first page of the parts\,%
         \footnote{From \TeX 's standpoint the command must occur
                   between the beginning and end of the page on which
                   the numbering is to begin.
                  }.
         It will often be useful in this case to use the option
         \texttt{c} , which by default causes the instrument name to be
         centered in small type at the top of every page after the
         first.
   \item _{MIDI!with \textbf{scor2prt}} \label{p:MIDI}
         MIDI commands, i.e., those starting with \texttt{I}, will never
         be copied into parts, unless they are in a special comment line
         as just described.
   \item _{rest!multibar rest}
         One function of \textbf{scor2prt} is to condense consecutive
         bars of rest into a single group of special printed characters
         with a number above it. Thus \textbf{scor2prt} will automatically
         insert \texttt{rm} symbols (cf.\ Sec.~\ref{sec:rests}) into the
         \texttt{.pmx} files for the parts where appropriate.  However,
         for this feature to work, the \emph{first} full-bar rest in the
         sequence \emph{must} have its duration explicitly defined in
         the parent file, either with a digit or with \texttt{p}.  In
         other words, the feature will not work if the first rest in the
         sequence inherits its duration from the previous note.
\end{itemize}

\bigskip
\Note{In standard {\TeX} the rule for comments is: a \% character
      \emph{and all text that follows it on the same line} is treated as
      a comment, i.e.\ it is totally ignored by the program. As a
      consequence of this rule, many users of {\TeX} have a habit of
      adding comments at the end of short lines of text, instead of
      writing a whole comment line, starting with a \% in column 1 .
      This is fine as far as {\PMX} is concerned; but
      _{\textbf{scor2prt}} \textbf{scor2prt} redefines this rule a bit
      and in general \emph{will misinterpret comments added in the same
      line after} some legal {\PMX} code. _{comments!usage with
      \textbf{scor2prt}}

      \medskip
      \emph{So when you intend to make parts using} \textbf{scor2prt},
      it is good practice to restrict true comments to lines with \%
      \emph{in column} 1, \emph{followed by at least one blank}.
     }

\section{Making MIDI Files}        \label{sec:MIDI}
_{MIDI}

Some users of {\PMX} and {\MusiXTeX} may never have heard of MIDI and
may therefore be a bit bewildered by this section. So here is a quick
introduction:
\begin{quotation}
   MIDI stands for ``\textbf{M}usical \textbf{I}nstruments
   \textbf{D}igital \textbf{I}nterface''. It is essentially a standard,
   consisting of a language and its hardware implementation, designed
   to produce digitally coded music with a device like a synthesizer or
   a multi-media computer. If your computer is equipped with the
   appropriate hardware and software (which is standard on PC's these
   days), you can listen to the music encoded in a MIDI file on your
   computer just as you can read the text encoded in a text file\,%
   \footnote{If you are interested in details on MIDI in general, a good
             place to start is the home page of the ``MIDI
             Manufacturer's Association'':
             \href{http://www.midi.org/about-midi/aboutmidi3.shtml}%
             {\texttt{http://www.midi.org/about-midi/aboutmidi3.shtml}%
             }~.
            }.
\end{quotation}

\bigskip
This section describes how to produce such MIDI files when writing a
piece of music with {\PMX}. When using this facility, you should be
aware both of the general restrictions of MIDI and the special ones that
{\PMX} imposes:

\begin{itemize}
   \item First of all, you should not expect the MIDI files that {\PMX}
         produces to be anything that resembles a performance of the
         piece by real, human musicians. While MIDI does make different
         shades of sound for the different instruments, the lack of any
         kind of expressivity (rhythmic accentuation, dynamics, vibrato,
         intonation etc.) does not really do justice to the musical
         character of acoustic instruments.

         \medskip
         So the MIDI file can be hardly more than an acoustic check on
         whether the notes produced are indeed what you had intended.
         But for that purpose it can be of great help in coding a score
         with {\PMX}, so it is generally advisable to produce the MIDI
         files.
   \item _{grace notes!not in MIDI} _{ornaments!not in MIDI}
          _{repeats!not in MIDI} _{volte!not in MIDI}
          _{volte!not in MIDI} _{slurs!in MIDI}
         \label{p:midi}
         The MIDI module of {\PMX} does not recognize graces, ornaments,
         repeats, volte, or segnos.  The only ties that are recognized
         are those using \texttt{s}, \texttt{t} or \texttt{(} \,; alone,
         with no explicit ID number.
   \item _{transposition!not with MIDI} _{octaviation!not with MIDI}
         Neither can the module reproduce music in which notes sound
         differently from what is written in the score. This pertains
         boths to transposing wind instruments and octaviation notation
         (cf.~Sections \ref{sec:mtrauer}, \ref{sec:clefoctaviation}).
   \item the MIDI file generator does not support changing the number of
         instruments in midstream. You will not see an error message,
         but the results will be unpredictable.
\end{itemize}

The MIDI file is produced by {\PMX} concurrently with the {\MusiXTeX}
output. To start this, enter the symbol \texttt{I}, together with any
options (as described below), usually in the header of the input file;
but \texttt{I} symbols can appear later in the file as well, but only at
the \emph{start of an input block}.
_{I symbol@\texttt{I} symbol}

If the name of the {\PMX} source file is, say, \texttt{Mymusic.pmx}, the
MIDI symbol \texttt{I} will cause a file \texttt{Mymusic.mid} to be
written in the directory given in the preamble. If \texttt{I} is used
without any options, {\PMX} will use default values for several of the
parameters; these default values are indicated below.

\medskip
Usually, however, you will want to specify some options. They follow the
MIDI symbol \texttt{I} immediately, without a space. Sometimes the order
of the options matters, so it is generally advisable to adhere to the
order in which they are given here:

\begin{enumerate}  _{MIDI!parameters}
  \item \texttt{t}[\emph{x}] sets the tempo to \emph{x}
        quarter notes per minute. Default is 96.  You can change the
        tempo as often as you like, but only at the start of an input
        block (as with all MIDI commands).
  \item _{instruments!names!in MIDI}
        \texttt{i}[\emph{i1i2...in}] assigns MIDI instrument names
        \emph{i1,i2,...,in} to the staves of the respective {\PMX}
        instruments. The default is harpsichord, of course.

        If you use this option, you must specify \emph{all} instruments.
        Each \emph{i} is either an integer between 1 and 255 or a
        2-letter mnemonic. The instrument mnemonics allowed with {\PMX}
        are listed in Table~\ref{tab:MIDIinstr}. Numbers and mnemonics
        may be mixed, but consecutive pairs of numbers must be separated
        by \texttt{:} (colon)\,%
        \footnote{Otherwise the assignment could be ambiguous!}.
        Care is needed with multi-staff instruments: there must be one
        instrument name \emph{per staff}; so for a sonata for violin and
        piano, e.g., the instrument names entry would be
        \texttt{ipipivl}, not \texttt{ipivl} !
  \item \texttt{v}[\emph{i1}]:[\emph{i2}]:[...]:\emph{in}] assigns the
        relative MIDI volume to each instrument. Each \emph{i} is an
        integer between 1 and 127; the colons are required. The volume
        parameter \texttt{v} must either be given with exactly as many
        parameters as there are instruments, or none at all. The default
        (no parameters given) is 127.
  \item \texttt{b}[\emph{m1}]:[\emph{m2}]:[...]:\emph{mn}] assigns the
        MIDI stereo balances to each instrument. The numbers \emph{m}
        may vary between 1 and 128; otherwise their usage is similar to
        that for the volume. The default value is 64, which represents
        the center; smaller numbers favor the left stereo channel,
        larger ones the right.
  \item \texttt{p}[\emph{x}] inserts a pause of \emph{x} quarter notes
        -- for all instruments! -- at the beginning of the first bar of
        the input block in which the MIDI symbol appears. Decimals are
        allowed, but will be rounded to the nearest sixteenth note.
  \item \texttt{g}[\emph{i}] sets the MIDI gap to \emph{i} MIDI clock
        tics: this is a silence inserted at the end of every note,
        while decreasing the sounding duration by the same amount. The
        default is 10, which corresponds to 2/3 of a 64th note.
\end{enumerate}

_{MIDI!file players and editors}
Key signatures, time signatures (meter) and instrument names will be
written into the MIDI file, the latter as track names.  This will have
no effect whatsoever on audible output, but will affect on-screen
appearance with some MIDI file players and editors.

\medskip
The instruments given in Table~\ref{tab:MIDIinstr} are a subset of
``The General MIDI Instrument Specification''. Of course how they sound
depends on your hardware and software. Instruments not listed below can
still be used but must be specified by number
(cf.~Table~\ref{tab:MIDIspecif}).

	\label{tab:MIDIinstr}
\end{table}

\subsection{MIDI macros \protect\footnotemark}
\footnotetext{{\PMX} normally does not allow tempo changes in MIDI macros.
          As of version 2.511, this restriction no longer holds; but it
          is designated as ``experimental''. So if you use it, be
          prepared for surprises! Naturally, Don Simons will certainly
          be interested to hear of your experiments.
         }

\texttt{IM} initiates a MIDI macro operation. Although the syntax of a
{\PMX} MIDI macro is analogous to that of regular {\PMX} macros
(decribed in Section~\ref{sec:macros}), its function is different:
\begin{enumerate}
  \item a MIDI macro cannot be saved (i.e.\ recorded without playing ---
        there is no command \texttt{IMS[}\emph{i}\texttt{]}),
  \item the code sandwiched between \texttt{IMR[}\emph{i}\texttt{]}
        (``start \textbf{r}ecord \textbf{M}IDI macro'') and \texttt{IM}
        (``end \textbf{M}IDI macro'') will be recorded as with a regular
        macro, but
  \item \texttt{IMP[}\emph{i}\texttt{]} (``\textbf{P}layback of
        \textbf{M}IDI macro \emph{i}'') will \emph{not insert anything
        in the written score}, it will merely replay in the MIDI output
        the number of bars defined by the macro.
\end{enumerate}
MIDI macros are needed for repeats or dacapos, as the {\PMX} coding for
these features of a score merely provides the appropriate notation on
paper, nothing else. MIDI Macros must have ID numbers between 1 and 20.
Only one macro may be active at a time, recording or playing, but not
both. Never try nesting or overlapping macros!

	\label{tab:MIDIspecif}
\end{center}
\end{table}

In rare cases a special notation for accidentals is needed to guarantee
that the MIDI output corresponds exactly to what is intended in the
score. Cases in point are:
\begin{description}
  \item[Repeated notes with accidentals:] the generally accepted rules
       of musical orthography, at least for tonal music, say that when
       two identical notes with accidentals occur in the same bar (and
       in the same voice, of course), only the first one is written with
       an explicit accidental; for the following notes the accidentals are
       implied (`inherited', in {\PMX} parlance).

       This rule is less clear when there is a bar line between two
       successive notes. Some composers -- in particular in the baroque
       era, where this notation is almost the default -- will assume the
       first note in the new bar to have `inherited' the accidental
       along with it, while others would insist on repeating the
       accidental, and still others would put a cautionary accidental
       over the first note of the new bar. {\PMX} takes the first
       position, and MIDI files generated by {\PMX} will reflect this
       attitude.

       {\PMX} users with a different attitude could thus find their
       intention misrepresented in the MIDI output.

  \item[Editorial/dubious accidentals:] in editing an historical piece,
       a conscientious editor will provide information about
       dubious points, but she nevertheless, in creating a MIDI file,
       might want to assert her own position.
\end{description}
For these and similar applications {\PMX} provides the \emph{MIDI only
accidentals}. These are written and used like normal accidentals,
except with an `\texttt{i}' added . Such accidentals are
effective \emph{only in the MIDI output}; they are disregarded in the
printed score.

This is particularly useful when you want to override the MIDI
``baroque default'' described above. To understand the ``baroque
default''  clearly, consider the example given in
Fig.\ref{fig:MIDIbaroquedefault} , where the {\PMX} coding is given
directly below the system:

\begin{figure}[!htb]
  \begin{center}
        \includegraphics[scale=.82]{eps/MIDIbaroque.eps}
	\caption{The ``baroque default'', and overriding it with MIDI
                 only accidentals}
	\label{fig:MIDIbaroquedefault}
  \end{center}
\end{figure}
\noindent
Now compare the printed score with the MIDI version -- provided
\href{http://www.itp.uni-bremen.de/~noack/MIDI.mid}{here} for your
convenience --, and you can hear the differences explicitly\,%
\footnote{It is also instructive to note the MIDI implementation of
          slurs and ties generated by {\PMX} here (Cf.\ the list of MIDI
          restrictions on p.\pageref{p:midi}).
         }.

\medskip
Another example for the use of MIDI only accidentals is given in
Fig.\ref{fig:MIDIaccidentals}:
\begin{figure}[!htb]
  \begin{center}
     \includegraphics[scale=.82]{eps/MIDI.eps}
  \end{center}
	\caption{Further use of MIDI only accidentals}
	\label{fig:MIDIaccidentals}
\end{figure}
\begin{itemize}
  \item MIDI plays the first $C$ in bar 2 as a $C\sharp$. The editorial
        $\natural$ over the second $C$, however, suggests that
        $C\natural$ was intended (at least from here on), so the MIDI
        accidental \texttt{in} is appended to that $C$,
  \item the final $F$ (in bar 5) suggested to the editor that we are
        moving towards F major here, and thus the $B$ in bar 3 should
        actually have been a $B\flat$. By bar 4 the assumption is
        confirmed, and so he changes the `dubious' accidental to an
        editorial one, and the MIDI only accidental \texttt{fi} is appended
        to that $B$.
\end{itemize}

\section{Lyrics}    \label{sec:lyrics}
_{\texttt{musixlyr.tex}}  _{\textbf{musixlyr}}
_{lyrics|see{\textbf{musixlyr}}}

{\PMX} has no special provisions for lyrics.  One way to include them is
by using the macro package \texttt{musixlyr.tex} developed by Rainer
Dunker.  It introduces lyrics into {\TeX} more easily than with
{\MusiXTeX}'s own facilities.  The macros could be entered as inline
{\TeX} directly into the \texttt{.pmx} file, but most would prefer the
convenient interface to \textbf{musixlyr} via the program {\MTX}
developed by Dirk Laurie (cf.~Section~\ref{sec:MTX}).
_{\MTX} _{Laurie, Dirk} _{Dunker, Rainer}

_{accented letters in lyrics}

If you have foreign-language lyrics, you may run into the problem of
accented letters. Straight {\TeX} does not provide these directly, as
the modern font encoding schemes used by {\LaTeX} do.
_{Vogel, Olivier}
However, Olivier Vogel has developped a method with which to use these
encoding schemes with {\MTX}/{PMX}/{\MusiXTeX}. For details you should
look at his contribution on this in the
\href{http://icking-music-archive.org/software/pmxtricks/tricks.html}%
     {Tricks and Tricks}
section in the WIMA, or contact Olivier directly: \quad
\raisebox{-0.8ex}{\includegraphics[scale=0.6]{addresses/ovogel} }

\section{{\PMX} and {\LaTeX} }    \label{sec:LaTeX}
_{\LaTeX}

{\LaTeX} (``A Document Preparation System''), although written for a
very different purpose, has a lot in common with
{\PMX}: it is a (huge) set of {\TeX} macros that allows to solve
complicated layout problems without the need to dive into the --
sometimes arcane -- depths of {\TeX} itself. So {\LaTeX} simplifies the
use of {\TeX} for the non-{\TeX}pert in much the same way that {\PMX}
does for {\MusiXTeX}.

\medskip
So it would certainly be wonderful to have the best of two worlds: merge
{\LaTeX} and {\PMX}. The problems with that (or merging {\LaTeX} and
{\MusiXTeX}, for that matter) are threefold:
\begin{enumerate}
  \item {\PMX} deals with many of the layout aspects of a musical score
        on its own (such as width of systems, line breaks, page breaks
        etc.), and with techniques that are not really compatible with
        those of {\LaTeX}.
  \item {\MusiXTeX} / {\PMX} and {\LaTeX} make heavy use of
        {\TeX}'s ressources, both in memory and registers, and together
        they may strain these ressources beyond their usual limit.
  \item both {\MusiXTeX} / {\PMX} and {\LaTeX} use many special
        command definitions, often enough incompatible with one another.
\end{enumerate}

While with modern implementations of ressources are no longer a serious
problem, the incompatibility problems are, and their resolution would be
a major programming task. So there have, to this day, not been any
serious efforts to provide a truly merged version of {\LaTeX} with
{\PMX}.

\bigskip
There are, however, several methods to use {\LaTeX} and {\PMX} in
(partial) ``coexistence'':
\begin{enumerate}
   \item          _{\LaTeX!with short musical scores} _{short scores}
         The best way to include short scores, of less than one printed
         page, in a {\LaTeX} document is to
         \begin{enumerate}
            \item _{PostScript}
                  produce the musical score with {\PMX} -- {\MusiXTeX}
                  -- \textbf{dvips} in the way described in this tutorial.
                  The end product is a PostScript file,
            \item _{encapsulated PostScript file}
                  _{\texttt{.eps} file|see{encapsulated PostScript file}}
                  make an \texttt{.eps} (``encapsulated PostScript'')\,%
                  \footnote{In general, this is possible for
                            single-page PostScript files only.
                           }
                  file from the \texttt{.ps} with one of the standard
                  tools, e.g.~\textbf{ghostview},
            \item include this \texttt{.eps} file in the {\LaTeX}
                  document with the {\LaTeX} \bs\texttt{includegraphics}
                  command, e.g. \\[-1ex]
                  \hspace*{\fill}\verb#\includegraphics[scale=0.58]{sample.eps}#
                  \hspace*{\fill} .
         \end{enumerate}
         This is the method with which the present tutorial was produced.
   \item _{\textbf{musixltx}}   _{\LaTeX!\textbf{musixltx}}
         use the {\LaTeX} package \textbf{musixltx}, together with
         {\MusiXTeX}\,%
         \footnote{\textbf{musixltx} is part of the standard
                   distribution of the {\MusiXTeX} package.
                  }.
         The {\MusiXTeX} code is then sandwiched between the start and
         end of a specific environment:
         \begin{center}  \vspace*{-2ex}
         \verb#\begin{music}# \dots \verb#\end{music}# .
         \end{center}\noindent
         For more detail on this method see the {\MusiXTeX} manual by
         Daniel Taupin.  _{Taupin, Daniel}

         \medskip
         But be aware of the fact that the \texttt{.tex} files produced
         by {\PMX} contain a number of incompatibilities with {\LaTeX}.
         So if you want to use the \textbf{musixltx} package together
         with {\PMX}, you may have to comment out a few lines in the
         \texttt{.tex} file --- by hand, unfortunately. For that reason,
         the \textbf{musixltx} package usually works well with {\PMX}
         only in rather simple cases. An example of how to proceed can
         be found in the WIMA: \\
         \hspace*{\fill}
         \href{http://icking-music-archive.org%
                    /software/musixtex/add-ons/pmx-l2e.tex}%
              {\texttt{http://icking-music-archive.org/%
                             /software/musixtex/add-ons/pmx-l2e.tex}}
         \hspace*{\fill} \\
   \item _{\LaTeX!\textbf{mtxlatex}}  _{\LaTeX!e\TeX}
         _{\LaTeX!interface with \PMX} _{Laurie, Dirk} _{\MTX}
         Dirk Laurie, the author of {\MTX}, has developped a
         {\LaTeX} package, \textbf{mtxlatex}. It is is part of the
         \href{http://icking-music-archive.org/software/mtx/mtx060.pdf}%
         {{\MTX} 0.60b distribution}, available from the WIMA, and can be
         considered a successor to the \textbf{musixltx} package
         described above. An outstanding feature of this package is that
         it interfaces quite well with {\PMX}; so this is usually the
         method of choice in cases where you want to include longer
         music scores in a long text such as a book. Detailed
         instructions on how to use this package are contained in the
         {\MTX} manual.

         When
         using \textbf{mtxlatex}, be sure to
         include the \textbf{mtxlatex} package as the
                  \emph{first} package in the {\LaTeX} source file.

\chapter{Limitations, error messages, and bugs}
\section{Limitations}  \label{sec:limits}
_{limitations}

For simplicity in writing the program, {\PMX} has numerous variables
with fixed dimensions. In most cases there are no checks against these
limits, so occasionally there may be hangups due to exceeding a
dimension.

\medskip
The limits of the variables given in Tables~\ref{tab:softlimits} and
\ref{tab:hardlimits} fall in two distinct classes, named ``soft'' and
``hard'' limits to distinguish them:
\begin{enumerate}
   \item soft limits can be increased fairly easily: all it takes (sic!)
         is to change the dimensions in the FORTRAN source of
         _{\texttt{pmxab.exe}} \texttt{pmxab.exe} (the {\PMX} program)
         accordingly, and recompile,
   \item hard limits, on the other hand, could only be increased with
         more or less elaborate reprogramming
         \footnote{Often these hard limits are a consequence of
                   features of {\MusiXTeX} and thus cannot be changed
                   without changes in {\MusiXTeX}.

                   Note, however, that this character count
                   \emph{includes all empty spaces before the final
                   character} (such as \texttt{/}) at the end of an
                   input line. If -- for better readability, e.g.\ --
                   you are in the habit of aligning these end-of line
                   characters, being more stingy on the resulting blanc
                   characters often helps to stay within the limit.
                  }
         (or at least recompiling the source code), so for all practical
         purposes they are unchangeable.

\end{enumerate}
In both cases, however, it will usually be possible to work within
existing limits by breaking the input into smaller blocks. Consider that
solution before asking Don Simons for changes to the {\PMX} source code,
or attempting such changes yourself! _{Simons, Don}

\section{{\PMX}'s error messages}   \label{sec:errormsg}
_{error messages}

When run on, say, \verb#my_opus.pmx#, {\PMX} will always generate two
files in the working directory, \verb#my_opus.pml# and
_{\texttt{pmxaerr.dat}} \texttt{pmxaerr.dat}. \verb#my_opus.pml# is a
log file, and \verb#pmxaerr.dat# contains a single integer: 0 if the run
was successful, otherwise the line number in the source file
\verb#my_opus.pmx# of the fatal error (useful for batch processing).
Also, on successful completion, \verb#my_opus..tex# will be placed in
the path specified in the preamble.

\medskip
Usually, when there is an error, {\PMX} will give you a pretty good
explanation\,%
\footnote{Note that sometimes an error message will use a name for a
          preamble numerical parameter that differs from that used in
          this tutorial --- but it usually is easily recognized.
          \label{p:errormsg}
         }.
There are some cases, however, in which the error message will be issued
not by {\PMX}, but by the FORTRAN compiler directly, and it may look
very cryptic to you. An infamous example is:
\begin{center} \vspace*{-1ex} \begin{verbatim}
          forrtl: severe (24): end-of-file during read, unit 10
\end{verbatim} \vspace*{-1ex} \end{center}
Such messages are almost always caused by an extra line in your source
file that shouldn't be there, so experiment with deleting lines towards
the end of your file!

\section{Bugs}
_{bugs}

As was mentioned before, {\PMX} is continuously maintained and improved
by Don Simons, and there is a very active group of {\PMX} users. Thus
there is no serious bug known (as of Version 2.514) that hasn't been
fixed. _{Simons, Don}

\medskip
If you think you have discovered a new bug, don't hesitate to send a
message to the TeX-music users' list:
   \raisebox{-1.0ex}{%
                    \includegraphics[scale=0.72]{addresses/texmusiclist}
                    }$\!\!$%
\footnote{Almost all reported ``bugs'' turn out to be misunderstandings.
          So if you state politely that you \emph{think} you may have
          found a bug, and ask for help, you will avoid irate replies of
          the ``RTFM'' species.
         }.
The same is true if you have a problem with {\PMX} that you simply cannot
solve by yourself, even though you suspect that it's \emph{not} a bug:
don't hesitate to ask!

\subsection{A Benign Bug}   \label{sec:bug}
When {\TeX}ing the output of {\PMX} you will usually get an
\texttt{Underfull \bs vbox} message at the end of each page.  This is
due to {\PMX} inserting \verb#\eject# at the end of every page, which
automatically spaces the systems vertically without having to fiddle
with \verb#\staffbotmarg#.  As far as is known, the warning is benign,
and may be ignored.

\section{Simple tricks}

\subsection{Special coding in L'Incoronazione di Poppea}
_{figured bass!continuation}

Bar 17 in Fig.~\ref{fig:poppea} requires an explanation: the
continuation figure appears under the \verb#5#, but the these two
figures are coded as \verb#x145 x12\_00.2# . Why not \verb#x14500.2# ,
giving them both the same horizontal offset? That is because the
continuation figure always starts 0.3 \verb#\noteskip#s to the
\emph{left} of the associated note's position. This works well in most
normal situations. But here \verb#\noteskip# is large,based on the
dotted half, while the desired length is short, so in fact the left
offset of the starting point is even larger than the desired length.
Consequently the entry point of the continuation figure has to be offset
by a half note to make it appear offset by a quarter note.

\subsection{Text after final system}
 _{text!after final system}
Suppose you want to add some text, Or any other {\TeX} material,
after the final system of a score. How can you include that in the
{\PMX} file?\,%
\footnote{This question was posted to the {\TeX}-music list by Herrmann
          Hinsch. _{Hinsch, Herrmann}
         }

The answer, given by Christian Mondrup, is instructive:
\begin{enumerate} _{Mondrup, Christian}
   \item Write the text to a separate file, say
         \verb#Myendnotes.tex# ,
   \item Insert
     \begin{center}\begin{verbatim}
     \let\Endpiecesav\Endpiece
     \def\Endpiece{\Endpiecesav\input Myendnotes}
     \end{verbatim}\end{center}
\end{enumerate}
in the header of the {\PMX} source file, i.e.\ as a Type 4 inline {\TeX}
command (cf.\ Sec.~\ref{sec:inlinetypefour}). You can see that the
redefinition of {\TeX} commands, if done carefully, can be a rather
powerful tool.

\medskip _{\LaTeX!interface with \PMX} _{\textbf{mtxlatex}}
Another solution to this problem is to use the {\LaTeX}/{\PMX}
interface \textbf{mtxlatex} (cf.~\ref{sec:LaTeX}); this may be
simpler in cases involving more complicated layout.

\subsection{Transposing wind instruments} \label{sec:mtrauer}
_{transposition}

Fig.~\ref{fig:mtrauermus} contains the first few bars of Mozart's
``Mauerische Trauermusik KV 477. Two features of this score are
remarkable from the point of view of {\PMX} coding (given in Table
\ref{tab:mtrauermus}):
\begin{enumerate}
   \item[a)] _{instruments!transposing}
         the Mauerische Trauermusik is a piece for 10 instruments\,%
      \footnote{You may have seen (or heard) this piece before with a
                total of 13 instruments: 2 more Corni di bassettto and a
                Gran Fagotto. These were in fact added to the score
                later on by Mozart himself; the score given here
                reflects the orchestra of the first performance (on 17
                Nov. 1785).
               },
      4 of which are ``transposing wind instruments'' : a clarinet in
      B~$\flat$, a corno di bassetto in F, and two horns in C~.
      Consequently the parts for these instruments must be written with
      a  key signature different from the rest of the orchestra (this is
      true also for the 2 horns, even though the piece is in C minor:
      horn parts are invariably written \emph{without any signature}).
      {\PMX} has no mechanism to do that, so once again you have to
      resort to inline {\TeX},
   \item[b)] as is usual with orchestral music, similar instruments are
      grouped together by accolades (square brackets). How do you do
      that in {\PMX}?
\end{enumerate}

\bigskip
The example exhibits both features. The header contains the following
Type 2 inline {\TeX} commands:
\begin{enumerate}
   \item[a)]  _{\MusiXTeX!\bs\texttt{setsign}}
           \begin{verbatim}
\\setsign{4}{0}\setsign{5}{0}\setsign{6}{-2}\setsign{7}{-1}\
             \end{verbatim}
      \verb#\setsign{n}{m}# sets the ^{key signature} of instrument $n$
      to $m$ sharps (or flats if $m<0$). So this sets the signatures for
      the transposing wind instruments. The {\PMX} notation of the notes
      is then, of course, as they are written, not as they sound, and it
      is the composers's responsibilty, as usual, to get all the
      accidentals right.

\bigskip\bigskip
\Note{As just explained, this use of \bs\texttt{setsign\{n\}\{m\}} is a
      purely notational device. A seasoned orchestra conductor, when
      seeing the notation (name of instrument, together with the key
      signature), \emph{might mentally}  `hear' the sound of a clarinet
      in B\,$\flat$ a full note lower than what he sees written in the
      score; but {\PMX} does \emph{not} know about this when producing a
      MIDI file from that score\,\footnotemark.

      _{`transposing' instruments!not in MIDI}
      The upshot of this is: when you have transposing instruments coded
      with \bs\texttt{setsign\{n\}\{m\}} in {\PMX}, don't produce a MIDI
      file; it would be \emph{meaningless}\,\footnotemark.
     } \label{p:mtrauer}
\addtocounter{footnote}{-1}
\footnotetext{This is to be clearly distinguished from a difference in
              clefs: the note on the middle line of a staff with a
              violin clef \emph{is} a \texttt{b}, whereas with a bass
              clef it \emph{is} a \texttt{d}, and a MIDI file produced
              by {\PMX} will reflect that correctly.

      \footnote{Note that the two violins as well as the two oboes are
                coded in this {\PMX} source as one two-stave instrument
                each, so that they are accoladed with curly brackets.
                Thus, from the {\PMX} point of view, the whole score
                logically comprises 8 instruments!
               },
      group 2 the 2 horns and the basset horn, group 3 the clarinet and
      the 2 oboes.
\end{enumerate}


\subsection{Clef octaviation}  \label{sec:clefoctaviation}
_{octaviation}

As was noted in Section~\ref{sec:octaviation}, {\PMX} does not
presently provide a notation for octaviation; but native {\MusiXTeX}
does; cf.~the {\MusiXTeX} manual, Sec.~2.11 for details.

\medskip
Consider, for example,  bar 155 of the $2^\text{nd}$ movement of
Beethovens piana sonata op.\ 111 :

\begin{center}
\includegraphics[scale=.82]{eps/beethoven0.eps}   \\[2ex]
        ------------------------------------------
\begin{minipage}{360pt}
\small
\begin{verbatim}
\\interstaff{13}\
w170m
Abepl
%
[ e83d ze+ e8- ze+ sl c1- zc+ sl ] c8d-l zc+ | Rb /
[l c15x3n g+ c   b1-x3n g+ b c1-x3n g+ c ]
[l gs1x3n b  gs+ g1-x3n b  e a1-x3n e+ a ]
[l a-1x3n e+ a   g1-x3n e+ g a1-x3n e+ a ] | /
%
\end{verbatim}
\end{minipage}
\end{center}
In most editions, you will find the figures in the right hand in the
second and third three beats written in octaviation notation:
\begin{center}
\includegraphics[scale=.82]{eps/beethoven1.eps}   \\[2ex]
\end{center}
which is clearly easier to read. This octaviated version was produced by
the following {\PMX} code:
\begin{center}
\begin{minipage}{360pt}
\small
\begin{verbatim}
\\interstaff{13}\
w170m
Abepl
\\def\octnumber{8$^{va}$}\
%
[ e83d ze+ e8- ze+ sfu c1- zc+ sfu  ] c8d-l zc+          | Rb /
[l c15x3n g+ c   b1-x3n g+ b c1-x3n g+ c ]
\Ioctfinup1d\ [l g-s1x3n b  gs+ g1-x3n b  e a1-x3n e+ a ]
[l a-1x3n e+ a   g1-x3n e+ g a1-x3n e+ a ] \toctfin1\    |    /
%
\end{verbatim}
\end{minipage}
\end{center}

The octaviation is started with the Type 1 inline {\TeX} symbol
\verb#\Ioctfinup1d\# and ended with \verb#\toctfin1\# ; the
transposition downward is, of course, generated in the standard {\PMX}
way by writing \verb#g-s1x3n# instead of \verb#gs1x3n# . By default,
{\MusiXTeX} will start the octaviation symbol with a simple \texttt{8};
this is changed to 8$^{va}$ by the Type 2 inline {\TeX} symbol given in
the preamble.

\medskip
\Note{When using this octaviation notation in a score, do not try to
      produce a MIDI file for that score: it will come out faulty
      (cf.~the Note on p.\pageref{p:mtrauer}).
     }

\section{More tricks}
The above examples are actually rather simple cases of the use of inline
{\TeX}, not really ``tricks''~; they have been included here for you to
`warm up' to doing such things yourself. But there are many
further-reaching tricks to overcome shortcomings of {\PMX} ---
some truly ingenious. Here are a few of general interest:

\subsection{Changing vertical positioning of instrument name}
\label{sec:shiftname} _{\textbf{scor2prt}!use of Ti}
_{\textbf{scor2prt}!adjusting instrument name}

When making parts from a score with \textbf{scor2prt}, you will
sometimes find the adjustment of the vertical position of the instrument
name not to your liking. In particular, if you have a tempo indicated in
a line of text above the first system (e.g.~``allegro''), you may find
that the instrument name of some (but not all) parts collides with the
tempo indication. How can you fix that?

\medskip _{\textbf{scor2prt}!usage} _{Van Ryckeghem, Andre}
         _{instruments!names} _{comments!usage with \textbf{scor2prt}}
A practical solution of this problem has been given recently by Andre
Van Ryckeghem. It is quite instructive to see in this example how
the mechanism of handing over commands to \textbf{scor2prt} operates:

Suppose that you are writing a string quartet, and the relevant part of
the preamble and header in the score are:
\begin{small}\begin{verbatim}
...
Violoncello
Viola
Violine II
Violin I
batt
./
h
Allegro
Abpl
...
\end{verbatim}\end{small}

After running \textbf{scor2prt}, you find that the allegro command is
positioned the way you want it, but the cello name collides fully, and
the Violino II slightly, with the ``allegro''. Therefore you want to
raise the cello by \texttt{3ex}, the Violin II by \texttt{1.5ex} . To do
so, replace the above part of the preamble and header in the score by
\begin{small}\begin{verbatim}
     ...
     %% Violoncello
     %1 \raise+3ex \hbox{Violoncello}
     Viola
     %%
     Violin II
     %3 \raise+1.5ex \hbox{Violin II}
     Violin I
     batt
     ./
     h
     Allegro
     Abpl
     ...
\end{verbatim}\end{small}
All the comment lines are disregarded in compiling the score; but in the
\texttt{.pmx} file for the cello, you will find
\begin{small}\begin{verbatim}
     Ti
     \raise+3ex \hbox{Violoncello}
     b
     ./
     h
     Allegro
     Abpl
     ...
\end{verbatim}
and in the part for the second Violin
\begin{verbatim}
     Ti
     \raise+1.5ex \hbox{Violin II}
     t
     ./
     h
     Allegro
     Abpl
     ...
\end{verbatim}\end{small}
which does what you want.

\vspace*{3cm}
\subsection{Xtuplets ending with a rest}
            \label{sec:Xtuplets ending with a rest}
                _{xtuplets!ending with a rest}

   As was pointed out in Section~\ref{sec:xtuplets}, \PMX\ does not
   allow a rest as the last note in an xtuplet.

   \medskip
   Can one find a way to circumvent this restriction? A pedestrian,
   awkward way around might be this: remembering that \PMX\ is a
   preprocessor for MusixTeX, and in a second pass \TeX\ processes the
   \PMX\ output, one could simply enter some arbitrary note in place of
   the desired rest, run \PMX\ , and then in the resulting \TeX\ file
   replace the arbitrary note \emph{manually} by the appropriate
   MusixTeX rest symbol \emph{before} running the file through \TeX\ for
   the the 2nd pass.

   This semi-solution however, has two major drawbacks:
   \begin{enumerate}
     \item it takes a certain amount of aquaintance with basic MusixTeX,
           so this is not for everyone;
     \item more dangerously, this hack goes away if and when you
           rerun \PMX\ ! So if you are still in the middle of a
           development, you may find yourself redoing the hack over and
           over, which could quickly become a real nuisance.
   \end{enumerate}

   Luckily, for xtuplets with stand-alone notes there now exists a real
   solution: an ingenious, generally usable inline {\TeX} method --
   developped by Don Simons -- solves the problem completely for
   unbeamed xtuplets. Here is a simple example with two such triplets:
   \begin{center}
      \includegraphics[scale=.82]{eps/triplerest.eps} \end{center}
   \newpage And this is the \PMX\ source text that creates these staves:

------------------------------------
\begin{verbatim}
2 2
2 4 0 0
0 0
0 3 20  0.12


tt
./
w100m
\\def\qpforqu{\let\qut\qu\def\qu##1{\qp\zcharnote{##1}{~}\let\qu\qut}}\
\\def\dsforcu{\let\cut\cu\def\cu##1{\ds\zcharnote{##1}{~}\let\cu\cut}}\

e4ax3 \dsforcu\ e \dsforcu\ e e4ax3 \qpforqu\ eD  /
e4ax3           e           e e4ax3           eD  /
\end{verbatim}
------------------------------------

As you can see, there are two inline commands of type 2, which are
therefore effective throughout the file (from where they are first
entered), then followed by two standard \PMX\ lines; the lower one (the
top staff) of these has the standard triplets, as demonstration, while
the upper one (bottom staff) shows the corresponding triplets with ending
rests.

The two inline \TeX\ commands produce the type of rest: \verb#\dsforcu#
stands for a quarter rest, and \verb#\qpforqu# for a half rest. Note
that these inline \TeX\ commands not only provide the correct graphics,
but \PMX\ considers them to have the corresponding duration values! So
if you use wrong ones, \PMX\ will complain in the usual way.

\medskip
Explaining the inline {\TeX} commands in detail would go beyond the
scope of this tutorial. But if you know some of the MusixTeX
terminology, you will recognize that these commands conform to the
MusixTeX names for quarter and half notes etc.\,%
\footnote{This knowledge may be useful if you want to produce more
          complicated xtuplets with ending rests than the simple
          examples given here. The new MusixTeX-T114 manual may be
          helpful in such cases. If that doesn't help: consult a
          {MusiXTeX}pert!
         }

The inline commands are then each followed by a dummy note. Usually it
is a good (and safe) habit to use the same note name as the last real
note in the xtuplet; but any {\PMX} note name is valid; variations can
produce surprising, but possibly useful grahical results. So if you feel
up to it, you can play with such variations!

\subsection{Shorthand notation for consecutive quavers}
      _{Van Ryckeghem, Andre} _{shorthand!for quavers} _{eighths}
      _{quavers|see{eighths}}
      _{shorthand!for quavers|see also tremolo}
   Often, in accompanying voices, in particular, there are several
   repeated quavers (eighth notes), e.g.~4 quavers to a half note. There
   is a commonly used shorthand notation for this that helps
   sight-reading enormously: a half-note, with a line through its stem,
   indicating the quavers.

   Fig.~\ref{fig:JChrBach} shows the beginning of the cello part of a
   Joh.\ Chr.\ Bach quartet. In this example an inline {\MusiXTeX} macro
   (devised by Andre Van Ryckeghem) provides this shorthand.

             _{shorthand!for semiquavers}

   need to consult the {\MusiXTeX} manual: you will find that all you
   need to do is to replace \bs\texttt{ibl0} and \bs\texttt{ibl0} by
   \bs\texttt{ibbl0} and \bs\texttt{ibbl0} , resp.


\subsection{Varying the stave sizes}  \label{sec:varstaves}
_{figured bass!varying staves sizes} _{\texttt{curly.tex}}
_{staves!varying size}

In modern editions of works with basso continuo e.g., the implementation
of the bass, as suggested by the editor, is often given in a staff using
a smaller size. {\MusiXTeX} does not support such a possibility.

\medskip      _{Molekwa, Mthimkhulu}
Fortunately, Mthimkhulu Molekwa has written two macros that provide
alternative solutions of this problem that are often sufficient. The
first, \verb#musixbar.tex#, which is included in {\MusiXTeX},
allows you to easily define a set of staves (the two bottom ones, in the
case of a basso continuo) that have common bar lines joining these
staves \emph{and only these}\,%
\footnote{Normally, {\MusiXTeX} will draw common bar lines for
          \emph{all} staves or for \emph{none}.
         }.

\medskip
The second macro, named \verb#curly.tex#\,%
\footnote{\texttt{curly.tex}, if not included in your {\MusiXTeX}
          installation, is available in the ``add-ons'' software
          section of the WIMA.
         },
provides a brace as an accolade of a set of staves\,% to be grouped
to\-gether\,%
\footnote{{\MusiXTeX} provides only the choir-type square accolades. For
          the practical usage of \texttt{curly.tex} see the Caccini
          example in the appendix, Fig.~\ref{fig:caccini}.
         }.

\medskip
Suppose we want to set a sonata for violin and basso continuo with
{\PMX}. There will be three staves: at the bottom the basso continuo
proper, then immediately above it, and grouped together with a brace
accolade (in a smaller size), its implementation, and above these the
violin staff.

To get this, do the following:

\begin{itemize}
   \item indicate in the preamble the number of instruments,
         \emph{three} in this case!
   \item add a Type 4) {\TeX} inline command at the beginning of
         the file, invoking the macros
         \verb#musixbar.tex# and \verb#curly.tex#, e.g.\,%
\footnote{The {\MusiXTeX} command
          \texttt{$\backslash$sepbarrules$\backslash$} sets the vertical
          bar to be discontinous, i.e.\ \emph{not} extend across
          different staves.
         }

         \end{verbatim}
         }


         \vspace*{-3ex}
        The command \verb#\interstaffsav{9}\# determines the extension
        of the brace (and can be adjusted). The command
	\verb#\\\indivbarrules\sepbarrule3\# says that the third staff,
        that for the violin, has its own discontinuous bar line, not
        joined with the other two.

	The second line contains two commands:
        \verb#\\setsize2\smallvalue# sets the size of staff 2 to be
        smaller, and \verb#\curlybrackets{{1}{2}}\# says which staves
        are to be accoladed, i.e.\ joined by the brace.
\end{itemize}
The file \verb#curly.tex# must, of course, be in a directory where
{\PMX} and {\TeX} can find it, viz.\ either in the current directory or
in one in which the other {\MusiXTeX} files are stored.

And finally, to show you what is possible, here is a special example of
using inline {\TeX}: it was contributed to the {\MusiXTeX} users' list
by Olivier Vogel. Here is the literal text of his contribution,
with the result shown in Fig.~\ref{fig:bruckner}:

Dear all,

I've got a score of ``\emph{Locus iste}'' by Bruckner, which begins with
the indication of the range of voices. I tried to reproduce the result,
and share with you my solution, since it seems to me to be an
interesting trick.

If you encounter a tricky {\PMX} problem that you think is of general
interest, so that it may have been solved by someone else already,
a good place to search is the
\href{http://icking-music-archive.org/software/pmxtricks/tricks.html}%
     { {\PMX} `Tips and Tricks'} section of the WIMA.

\medskip
And if you have found a nice trick yourself, don't hesitate to
share it via the TeX-music users' list. Perhaps it can be included in
`Tips and Tricks' !

\chapter{An Extension of {\PMX}: {\MTX}} \label{sec:MTX}
_{\MTX} _{Laurie, Dirk}

Although {\PMX} is already vastly simpler to use than {\MusiXTeX},
anything can be improved. So Dirk Laurie
_{Laurie, Dirk}
set out to simplify {\PMX} even further, and thus created {\MTX}.

\medskip
{\MTX} is actually a preprocessor to {\PMX}. Its input is a file with
extension \verb#.mtx# , for example ~\verb#mymadrigal.mtx# , its output
has the extension \verb#.pmx# , \verb#mymadrigal.pmx#. Its input
language is similar, but not identical, to that of {\PMX} and includes
most of the functionality of {\PMX} as a subset.

\medskip _{\textbf{musixlyr}}
The major purpose of {\MTX} is to facilitate the introduction of lyrics
in a musical score of a song, cantata or opera. {\MTX} does this in
conjunction with the \textbf{musixlyr} package by Rainer Dunker; so if
you want to use {\MTX}, you ought to have \textbf{musixlyr} installed as
well. _{Dunker, Rainer}

\bigskip _{Laurie, Dirk}
Laurie's Work on {\MTX} had essentially been ended in November 1998 with
the `final' version 0.52. But, as many such projects, {\MTX} continued
to evolve; presently, the `official' version is 0,60, dated March 2005,
and the current patch is 0.60c , dated 22 November 2007 !

\bigskip
Since there is a full
\href{http://icking-music-archive.org/software/mtx/mtx060.pdf}%
              {manual on {\MTX}}
available in WIMA, these few remarks may suffice here.

\chapter{Appendix: Examples} \label{sec:examples}

\section{Dons Example Files}   \label{sec:donsexamples}

The `official' distribution files for {\PMX},
which are available from WIMA
\href{http://icking-music-archive.org/software/pmx/pmx2514.zip}%
     {[(pmx2514.zip)]},
, contain 3 instructive examples (not reproduced here):

\begin{description}
   \item[\texttt{most.pmx}] contains examples of most
         of the {\PMX} commands, and a few programming tricks, including
         examples in the last line of beam groups whose notes vary
         widely in pitch.  The printed output displays the {\PMX}
         commands near to the resulting typeset characters. It is more
         useful to look at the printed output rather than the source
         file, since the file is littered with Inline \TeX ~needed to
         output the text strings representing the {\PMX} commands.
         \textbf{WARNING:} Do not try to play this music; it could be
         hazardous.
   \item[\texttt{barsant.pmx}]
         _{\PMX!options!global} _{S symbol@\texttt{S} symbol}
         contains the first movement of a recorder sonata by the Italian
         Francesco Barsanti (1690-1772).  It demonstrates many of
         {\PMX}'s strong points in a `battlefield situation':  figured
         bass, complex beaming patterns, xtuplets, and automatically
         adjusted horizontal and vertical spacing in crowded scores. In
         fact, this single-page score is at the limit of vertical
         crowding. It uses the global option \texttt{Ae} for equal space
         betweem systems. The space between systems was increased (using
         the option \texttt{AI1.1}) to give a more pleasing appearance.
         This is a good score to try making parts with
         \textbf{scor2prt}. The special command \texttt{\%2S9} is used
         to increase the number of systems in the recorder part (as
         explained in Section \ref{sec:Ssymbol}).

   \item[\texttt{mwalmnd.pmx}] is an Allemand for harpsichord by the
         German Matthias Weckmann (1616-1674).  It uses many techniques
         peculiar to keyboard scores.
\end{description}


\section{Full-score examples} \label{sec:fullexamples}

_{Cataldi, Luigi}
In this appendix you will find the {\PMX} code (by Luigi Cataldi) of
a full piece, together with the actual score which was generated from it
(Section~\ref{sec:Dufay}), as well as two extended {\MTX} examples (also
coded by Luigi Cataldi).

\medskip
The {\PMX} code for the Dufay Kyrie contains a few inline {\TeX}
commands; this is done intentionally so you again can get a feel of the
usage of inline {\TeX}; to understand them fully, however, you will have
to consult the {\MusiXTeX} documentation.Similarily, you can get an idea
from the Vivaldi and Caccini example what {\MTX} is all about. For a
full understanding, you again need to look at the {\MTX} documentation.
