Thanks for that. I have tried the file, and although it does not produce any errors, it does not seem to change the output at all. So it may be that I am doing something wrong. Here is what I have done. Firstly, the final function now reads: combineMMRests = #(define-music-function (parser location music) (ly:music?) (condense music) music) I'm not entirely sure I have got this right! Secondly, in the section of my main file which produces a part for a instrument, I have: \score { \combineMMRests { \myMusic } \layout { } } Is this correct? At the top of my file, of course, I have: \include "combineMultimeasureRests.ily" David _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
