Editing Adding extra fingering with Scheme

You can add additional elements to notes using <code>map-some-music</code>. In this example, an extra script is attached to a note (or a chord).

In general, you should first apply <code>\displayMusic</code> to music similar to what you want to create so that you can see its structure.  This can be then used as template for your Scheme code.

addScript =
#(define-music-function (script music) (ly:event? ly:music?)
   (map-some-music
    (lambda (mus)
      (define (append-script-at! prop)
        (set! (ly:music-property mus prop)
              (append (ly:music-property mus prop)
                      (list (ly:music-deep-copy script))))
        mus)

      (case (ly:music-property mus 'name)
        ((EventChord)
         (append-script-at! 'elements))
        ((NoteEvent)
         (append-script-at! 'articulations))

  \addScript _6 { c'4-3 <c' e' g'> }
