You're missing the bit I hadn't said. I've already had about 6 explicit clef changes, using \clef "treble_8" and \clef "treble". It's a situation where I've been a bit lazy and copied the original score exactly, with 2 singers, a tenor and an alto, sharing a staff. (stave? :-) ). The final change is from alto to both singing, and those changes (tenor->alto and alto->both) are both flagged with a treble clef.
Sorry, in a hurry and not tested, but try \set Staff.forceClef = ##t HTH, Alexander _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
