\transpose c $trans { \firstNotes } <string>:2:17: error: syntax error, unexpected MUSIC_IDENTIFIER, expecting NOTENAME_PITCH or TONICNAME_PITCH
The only solution i know is to use the scheme equivalent of \transpose : ly:music-transpose But it is a bit harder... %%%%%%%%%%%%%%%%%%%%%%%% firstNotes = \relative c' { c4 d e f } first = #(define-music-function (parser location trans)(ly:music?) (let* ( (trans-note (car (ly:music-property trans 'elements))) (trans-pitch (ly:music-property trans-note 'pitch)) (delta-pitch (ly:pitch-diff trans-pitch (ly:make-pitch -1 0 0)))) ;% (display delta-pitch)(newline) (ly:music-transpose (ly:music-deep-copy firstNotes) delta-pitch) )) \score {<<\new Staff \firstNotes \new Staff \first d \new Staff \first e
>> } %%%%%%%%%%%%%%%%%%%%%%% Gilles
