Numbers as easy note heads
Easy notation note heads use the note-names property of the NoteHead object to
determine what appears inside the note head. By overriding this property, it
is
possible to print numbers representing the scale-degree.
A simple engraver can be created to do this for every note head object it sees.
#(define Ez_numbers_engraver
(list
(cons 'acknowledgers
(list
(cons 'note-head-interface
(lambda (engraver grob source-engraver)
(let* ((context (ly:translator-context engraver))
(tonic-pitch (ly:context-property context 'tonic))
(tonic-name (ly:pitch-notename tonic-pitch))
(grob-pitch
(ly:event-property (event-cause grob) 'pitch))
(grob-name (ly:pitch-notename grob-pitch))
(delta (modulo (- grob-name tonic-name) 7))
(note-names
(make-vector 7 (number->string (1+ delta)))))
(ly:grob-set-property! grob 'note-names note-names))))))))
