I’ve done something like this for transcribing solfege music (while retaining
English note names for other purposes):
myNames = #(append (assoc-get 'english language-pitch-names)
`(
(do . ,(ly:make-pitch -1 0 NATURAL))
(re . ,(ly:make-pitch -1 1 NATURAL))
(mi . ,(ly:make-pitch -1 2 NATURAL))
(fa . ,(ly:make-pitch -1 3 NATURAL))
(sol . ,(ly:make-pitch -1 4 NATURAL))
(la . ,(ly:make-pitch -1 5 NATURAL))
(ta . ,(ly:make-pitch -1 6 FLAT))
(ti . ,(ly:make-pitch -1 6 NATURAL))
))
solfegenglish = \myNames
#(ly:parser-set-note-names solfegenglish)
You should be able to adapt this for any particular set of note names you want.
