# Music in Plain Text
Jonathan Gregory

LilyPond is an extensible program for producing high-quality sheet
music engraved with traditional layout rules.  Similar to LaTeX and
other typesetting programs, its input format simply describes the
visual layout of the score using commands to define musical
expressions.  This makes collaboration easier, prevents users from
having to adjust layout settings manually, and faciliates digital
archiving and distribution of musical scores.  In this talk, I begin
by showcasing LilyPond syntax and mode using literate programming
techniques as examples for building sheet music in Emacs, and proceed
with an overview of the setup I use for producing music books with GNU
Make, LilyPond, and LilyPond-mode.
