A3 book

[Federico Bruni]

Hi all,

I'm using lilypond-book and LaTeX to gather some .ly files together in 
a book.
It worked well with A4 settings..

Now I need to change to A3 (because the printer shop says it can print 
easily in A3 if the source file is A3).
So the document must be twoside, which is the default setting in the 
book class.
Unfortunately, the output is still oneside. Even if I specify twoside 
in the documentclass preferences, nothing changes.

What am I doing wrong?


This is my book.lytek:

\documentclass[a3paper]{book}
\usepackage {graphicx}
\usepackage {fullpage}


\begin {document}
\setlength{\oddsidemargin}{-1.3cm}
\setlength{\topmargin}{5pt}
\setlength{\footskip}{4pt}
\setlength{\voffset}{1.5pt}


\chapter*{Blues per un Albero}
\lilypondfile[noindent,line-width=18\cm,staffsize=22.45]{ly/BluesPerUnAlbero.ly}

% and the other files

\end{document}
