Another shot: if what you need is to compile all *.ly below a folder, this 
might serve:

find . -name '*.ly' | while read i; do lilypond "$i"; done

Using read takes care of whitespace.

Or, more compact:

find . -name '*.ly' -exec lilypond '{}' \;

Although this won't work if the file must be inside a folder complying with 
the number pattern.
