\section{LilyPond-book + LaTeX}

This is an examplefile for mixing LilyPond and Latex. It is also
used to test lilypond-book. View the source to see how it is done.

A simple scale:

{%
\parindent 0pt
\ifx\preLilyPondExample \undefined
\else
  \expandafter\preLilyPondExample
\fi
\def\lilypondbook{}%
\input 89/lily-54f49c62-systems.tex
\ifx\postLilyPondExample \undefined
\else
  \expandafter\postLilyPondExample
\fi
}

LilyPond-book searches for the \verb|\score| command when it decides
if the code is only a fragment. Thus, in the following code, you have
to use \verb|fragment| option, because the comment confuses lilypond-book.

{%
\parindent 0pt
\ifx\preLilyPondExample \undefined
\else
  \expandafter\preLilyPondExample
\fi
\def\lilypondbook{}%
\input 5b/lily-b9f2d3b1-systems.tex
\ifx\postLilyPondExample \undefined
\else
  \expandafter\postLilyPondExample
\fi
}

There is also a shorthand version: \begin{verbatim}\lilypond[fragment]{c' e' g'}\end{verbatim}
%\verb|\lilypond[fragment]{c' e' g'}|   doesn't work!!!

{%
\parindent 0pt
\ifx\preLilyPondExample \undefined
\else
  \expandafter\preLilyPondExample
\fi
\def\lilypondbook{}%
\input c0/lily-921c3552-systems.tex
\ifx\postLilyPondExample \undefined
\else
  \expandafter\postLilyPondExample
\fi
}

that is the same as writing
\begin{verbatim}
\begin[fragment]{lilypond}
c' e' g'
\end{lilypond}
\end{verbatim}

This C major
%%\begin[staffsize=11\pt,fragment]{lilypond}
{%
\parindent 0pt
\ifx\preLilyPondExample \undefined
\else
  \expandafter\preLilyPondExample
\fi
\def\lilypondbook{}%
\input 84/lily-ad5965b2-systems.tex
\ifx\postLilyPondExample \undefined
\else
  \expandafter\postLilyPondExample
\fi
}
and C minor
{%
\parindent 0pt
\ifx\preLilyPondExample \undefined
\else
  \expandafter\preLilyPondExample
\fi
\def\lilypondbook{}%
\input 39/lily-21112fa6-systems.tex
\ifx\postLilyPondExample \undefined
\else
  \expandafter\postLilyPondExample
\fi
}  chords are floating inside the text.


\subsection{The 'verbatim' and 'intertext' option}
This shows the verbatim option:
\noindent
\begin{verbatim}
c' d' e'
\end{verbatim}
{%
\parindent 0pt
\ifx\preLilyPondExample \undefined
\else
  \expandafter\preLilyPondExample
\fi
\def\lilypondbook{}%
\input ae/lily-f8959a36-systems.tex
\ifx\postLilyPondExample \undefined
\else
  \expandafter\postLilyPondExample
\fi
}

NB: 'intertext' doesn't work.

\subsection{LaTeX comments}
This is a line with lilypond code
after the comment char % \lilypond{\context Voice <<c' e' g'>>}
% \lilypond{\context Voice <<c' e' g'>>}

If you do not see any music from the heading 'LaTeX comments' and until
this line, then lilypond-book is handling latex comments pretty well :-)

\subsection{To float or not to float}
This music
{%
\parindent 0pt
\ifx\preLilyPondExample \undefined
\else
  \expandafter\preLilyPondExample
\fi
\def\lilypondbook{}%
\input f7/lily-793d87f9-systems.tex
\ifx\postLilyPondExample \undefined
\else
  \expandafter\postLilyPondExample
\fi
}
should be floating inside the text by using the \verb|eps| options.

This music

{%
\parindent 0pt
\ifx\preLilyPondExample \undefined
\else
  \expandafter\preLilyPondExample
\fi
\def\lilypondbook{}%
\input f7/lily-793d87f9-systems.tex
\ifx\postLilyPondExample \undefined
\else
  \expandafter\postLilyPondExample
\fi
}

has also the \verb|eps| options, but is not floating because there
are empty lines before and after the lilypond block. That is
correct behaviour because it follows La\TeX{} convention that an
empty line signals a new paragraph. The \verb|eps| option
is not necessary when you want the music in a paragraph on its own.
