Re: Problem with grace note on first beat of first bar

[David Bobroff]

I only glanced at your PDF output but I suspect you've hit a known issue 
and there is a workaround.  See:

http://lilypond.org/doc/v2.11/Documentation/user/lilypond/Special-rhythmic-concerns#Grace-notes

Scroll down to "Known issues and warnings."  There are examples there 
concerning repeat bars and grace notes.  I think that clef changes 
likely lead to this problem as well.

Hope this helps,

David
