I think you've misinterpreted "part" as part of a movement, rather than part being an instrumental part. The OP will want to set the music as: movement1_part1 = { notes, notes, and more notes } movement2_part1 = { notes, notes, and more notes } movement3_part1 = { notes, notes, and more notes } to do what they posted, ie, \relative c { \movement1_part1 \movement2_part1 \movement3_part1 } This will enable them to set part2 for a high- or low-pitched instrument with one modification, and without changing the pitch of part1: \relative c' { \movement1_part2 \movement2_part2 \movement3_part2 } or \relative c, { \movement1_part2 \movement2_part2 \movement3_part2 } Cheers, David.
