There are a number of useful functions: musicMap (defined in
ly/music-functions-init.ly); for-some-music, map-some-music,
fold-some-music (in scm/music-functions.scm). Maybe
I don't know how to for-each on a music object.

ould iterate on the list:
(list #{ << a4 d'4 >> << b4 c'4 >> << c'4 b4 >> << d'4 a4 >> #})
and then I would use ly:pitch-semitones to calculate the difference and do
the transpose.
Thank you for your help
