I wanted to thank everybody for the help. I had it all mixed up. The shortInstrumentName must come before the \trumpet part, etc. otherwise it won't work.
I forgot to group with curly braces as well. This worked like a charm though: \book { \score { << \new StaffGroup = "horns" << \new Staff = "trumpet" \transpose c c { \set Staff.shortInstrumentName = "Tpt " \trumpet } \new Staff = "clarinet" \transpose c c { \set Staff.shortInstrumentName = "Clr " \clarinet } ... _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
