hi MING TSANG your score involves 5 parts of which at least 2 are empty:
\score { << \sopranoVoicePart \altoVoicePart \tenorVoicePart \bassVoicePart \pianoPart >> if you could send only the parts which produce the error (one is enough) and reduce that part to the error producing measures it would be much easier to search the error! thanks Eluze -- View this message in context: http://lilypond.1069038.n5.nabble.com/UnquieContext3-tp136667p136685.html Sent from the User mailing list archive at Nabble.com. _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
