Re: accord sur basse

Voilà la réponse pour ceux que ça intéresse.

#(define (rootless-chord-names in-pitches bass inversion context)
   (ignatzek-chord-names `(,(ly:make-pitch 0 0 0) ,(ly:make-pitch 0 0
0)) bass inversion context))

#(define (empty-namer pitch lower?) (make-simple-markup ""))

retainChordNoteNamer =
\applyContext
  #(lambda (context)
     (let ((rn (ly:context-property context 'chordRootNamer)))
       (ly:context-set-property! context 'chordNoteNamer rn)))

rootless = {
  \retainChordNoteNamer
  \once \set chordNameFunction = #rootless-chord-names
  \once \set chordRootNamer = #empty-namer
}

After that, one can use \rootless as follows:

fis2:m7.9 \rootless fis4:m7.9/f \rootless fis4:m7.9/e \rootless
fis1:m7.9/dis
