I believe you mean the GPL? no, it's not a violation. You can do
whatever you want with the output lilypond generates. The license
applies to the source code of the program itself (i.e. the source code
of lilypond).

none, but you are welcomed to keep the "Music engraving by lilypond" tag in
your files. Or better yet, mention lilypond in the colophon section. Or
even better, if you make lots of money selling the book, consider making
a donation to the project. :-)
