[gsharp-cvs] CVS update: gsharp/Scores/rapsoden-sjunger.gsh
by crhodes＠common-lisp.net 21 Nov '05

21 Nov '05

Update of /project/gsharp/cvsroot/gsharp/Scores In directory common-lisp.net:/tmp/cvs-serv16314 Modified Files: rapsoden-sjunger.gsh Log Message: Adjust rapsoden-sjunger to cope with the new semibreve rest. (Make some other minor changes to rest vertical positions: I don't know whether the original positions were meant to reflect some notated score, but the ones I've put in look better to me...)
