Using Lilypond with LaTeX

[S L Raymond]

I'm incorporating musical examples into a textbook using lines like
this:

\begin{center}
\includegraphics*[viewport=62 700 550 830]{AtoG.pdf}
\end{center}

The pdf in the above example contains a single staff.  When the book is
rendered, the graphic extends too far into the right margin.  My
question is twofold:

1.  How can I reduce the size of the staff?
2.  Is there a way to temporarily expand the left margin?
