G. L. Sicherman. Last revised 2003-05-17. +% +% MusiXTeX is free software, licensed under the GNU General Public +% License. This file is also free software. You may use it and +% modify it as you please so long as you leave this message intact. +% +% To use this file with MusiXTeX, refer to it in your source code +% after MusiXTeX: +% +% \input musixtex +% \input tuplet +% +% This file uses macros defined in musixtex.tex. +% +% Standard MusiXTeX uses \uptrio and \downtrio to print tuplet brackets. +% This file defines \uptuplet and \downtuplet, with the same arguments: +% +% #1 : starting pitch +% #2 : width of bracket, in (\noteskip)s +% #3 : slope of bracket, in multiples of 1-1/8 degrees +% +% The user defines the text to appear in the opening as \tuplettxt. +% This is to avoid conflicting with the \txt in standard MusiXTeX. +% +% Examples: +% +% Draw a triplet bracket over the notes, starting at pitch "p", +% 1.25\noteskip wide, with a slope up of 3-3/8 degrees: +% +% \uptuplet p{1.25}3 +% +% Draw a sextuplet bracket over the notes, starting at pitch "a", +% 2.5\noteskip wide, with a slope down of 4-1/2 degrees: +% +% \def\tuplettxt{\smallppff 6\/\/} +% \downtuplet{a}{2.5}{-4} +% +% Send comments, complaints, and bouquets to the Colonel at +% <colonel@monmouth.com>. +% +\makeatletter % Names of internal macros contain atpersats. + +% Standard MusiXTeX prints a small "3" (or other number) within +% the bracket.
