+xpiano - An extension of piano.sty by Émile Daneault
+====================================================
+
+This package is an extension of piano.sty, written in expl3
+in answer to a couple of questions on TeX.StackExchange
+
+ http://tex.stackexchange.com/questions/162184/
+ http://tex.stackexchange.com/questions/246276/
+
+It features extended syntax and several options, like setting
+the color, adding numbers for pitch analysis, one or two
+octaves and others.
+
+Installation
+------------
+
+The package is supplied in .dtx format; run 'tex xpiano.dtx'
+for extracting the style file and 'pdflatex xpiano.dtx' for
+building the documentation.
+
+Note that this package requires LaTeX3 support.
+
+License

+%
+%\section{Introduction}
+%
+% Simple keyboard representations can be useful for people involved
+% in music. This package builds upon \pkg{piano.sty} by \'Emile
+% Daneault (available on CTAN), adding several features:
+%\begin{itemize}
+% \item the number of notes is arbitrary;
+% \item the color of the circles is customizable;
+% \item the number used for pitch analysis can be shown;
+% \item the width of the keys and the length of the black keys
+% are customizable;
+% \item it's possible to show one or two octaves, optionally
+% adding a trailing C;
+%\end{itemize}
+% The package provides the commands
+%\begin{itemize}
+% \item \cs{keyboard}\oarg{options}\marg{notes}
+% \item \cs{keyboardsetup}\marg{options}
+% \item \cs{Keyboard} with up to seven optional arguments
+%\end{itemize}
+% The last command is intended for users of \pkg{piano.sty}
+% who can recycle their diagrams by just changing the lowercase
+% \cs{keyboard} into \cs{Keyboard} with no other change.
+%
+%\section{Usage}
+%
+% The basic command is \cs{keyboard}, which takes as mandatory
+% argument the list of notes to mark. The notes can be expressed in
+% different ways:
+%\begin{itemize}
+% \item the convention of \pkg{piano.sty} where they are\\
+% \texttt{Co Cso Do Dso Eo Fo Fso Go Gso Ao Aso Bo}\\
+% \texttt{Ct Cst Dt Dst Et Ft Fst Gt Gst At Ast Bt}
+% \item the German names\\
+% \texttt{C~~Ciss~~D~~Diss~~E~~F~~Fiss~~G~~Giss~~A~~Aiss~~B}\\
+% \texttt{C'~Ciss' D' Diss' E' F' Fiss' G' Giss' A' Aiss' B'}
+% \item the English names\\
+% \texttt{C~~Cs~~D~~Ds~~E~~F~~Fs~~G~~Gs~~A~~As~~B}\\
+% \texttt{C' Cs' D' Ds' E' F' Fs' G' Gs' A' As' B'}
+% \item the ``pitch analysis'' convention\\
+% \texttt{0~~1~~2~~3~~4~~5~~6~~7~~8~~9~~10~~11}\\
+% \texttt{0' 1' 2' 3' 4' 5' 6' 7' 8' 9' 10' 11'}
+%\end{itemize}
+% In the lists above, the lines denote the first and second octaves,
+% respectively. For the German style names, the enharmonic equivalents
+% are also available, \texttt{Dess Ess Gess Ass Bess} (with the primed
+% correspondents).
+%
+% The example in the documentation of \pkg{piano.sty} can so be input
+% in any of the following equivalent forms
+% \DescribeMacro{\keyboard}\DescribeMacro{\Keyboard}
+%\begin{flushleft}\ttfamily
+% \cs{Keyboard}[Co][Eo][Gso][Ct][Et]\\
+% \cs{keyboard}\{Co,Eo,Gso,Ct,Et\}\\
+% \cs{keyboard}\{C,E,Giss,C',E'\}\\
+% \cs{keyboard}\{C,E,Gs,C',E'\}\\
+% \cs{keyboard}\{0,4,8,0',4'\}
+%\end{flushleft}
+% producing the following diagram
+%\begin{center}
+% \keyboard{Co,Eo,Gso,Ct,Et}
+%\end{center}
+%
+% Each \cs{keyboard} command can receive an optional argument, where
+% options for drawing the keyboard are set with a key-value syntax.
+% The keys are listed in table~\ref{tab-keys}. As usual, the boolean
+% valued keys can be simply specified by name, the \texttt{=true}
+% value is implicit. The default \texttt{pianodefault} color is
+% defined as in \pkg{piano.sty} by \verb|\definecolor{pianodefault}{RGB}{255,127,0}|.
+%
+%\begin{table}[htp]
+% \centering\small
+% \caption{The keys for setup}\label{tab-keys}
+% \medskip
+%\begin{tabular}{>{\ttfamily}lll>{\raggedright\arraybackslash}p{.4\textwidth}}
+% \toprule
+% Key & Type & Default & Explanation \\
+% \midrule
+% color & Literal & \texttt{pianodefault} & The color of the note markers \\
+% single & Boolean & \texttt{false} & Draw just one octave \\
+% ext & Boolean & \texttt{false} & Add a trailing C \\
+% size & Dimension & \texttt{0.5cm} & The width of a white key \\
+% height & Numeric & \texttt{4} & The ratio between height and width of white keys \\
+% ratio & Numeric & \texttt{0.75} & The ratio between the height of the black and the white keys \\
+% numbers & Boolean & \texttt{false} & Show the pitch analysis number \\
+% font & Literal & \cs{tiny} & The font specification for the number \\
+% numbercolor & Literal & \texttt{black} & The color of the numbers \\
+% 10 & Literal & \texttt{10} & The representation of the number~10 \\
+% 11 & Literal & \texttt{11} & The representation of the number~11 \\
+% \bottomrule
+%\end{tabular}
+%\end{table}
+%
+% The settings to the key in the optional argument to \cs{keyboard} is
+% local to the diagram being drawn. For instance, the following input
+% will mark all possible notes in one octave with $t$ and $e$ for ten and eleven as
+% numbers:
+%\begin{flushleft}\ttfamily
+% \cs{keyboard}[\\
+% ~~single,\\
+% ~~ext,\\
+% ~~size=1cm,\\
+% ~~font=\cs{small},\\
+% ~~numbers,\\
+% ~~ratio=0.67,\\
+% ~~10=\$t\$, 11=\$e\$,\\
+% ]\{C,Cs,D,Ds,E,F,Fs,G,Gs,A,As,B,C'\}
+%\end{flushleft}
+%\begin{center}
+% \keyboard[
+% single,
+% ext,
+% size=1cm,
+% font=\small,
+% numbers,
+% ratio=0.67,
+% 10=$t$, 11=$e$,
+% ]{C,Cs,D,Ds,E,F,Fs,G,Gs,A,As,B,C'}
+%\end{center}
+%
+% \DescribeMacro{\keyboardsetup}
+% The \cs{keyboardsetup} command can be used to set the options from
+% one point on; the best place is of course the preamble, so the
+% choice will affect all diagrams. However this command obeys the
+% usual scoping rules. For instance, if you want most of your diagrams
+% to have the pitch numbers and be larger than the standard ones, you
+% can say in the preamble
+%\begin{flushleft}\ttfamily
+% \cs{keyboardsetup}\{\\
+% ~~numbers,\\
+% ~~size=0.8cm,\\
+% ~~ratio=0.67,\\
+% ~~font=\cs{small},\\
+% ~~10=\$t\$, 11=\$e\$,\\
+% \}
+%\end{flushleft}
+% and specify \texttt{numbers=false} in the optional argument to
+% \cs{keyboard} for the occasional diagram which you don't want to be
+% numbered.
+%
+%\section{Cautions}
+%
+% The \texttt{color} key accepts any color in the syntax of the
+% \pkg{xcolor} package. Note that the package is loaded without
+% options, so if you want to load it with some options (or load a
+% package that does so), you must do it before loading \pkg{xpiano}.
