\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
>>
}
