There are several parser limitations you're encountering here. The
only way around them is to stay in scheme when creating the new chord:
artHarm =
#(define-music-function (parser location note) (ly:music?)
(let ((harm (ly:music-transpose (ly:music-deep-copy (car
(ly:music-property note 'elements)))
(ly:make-pitch 0 3 0))))
(set! (ly:music-property harm 'articulations)
(list (make-music 'HarmonicEvent)))
(set! (ly:music-property note 'elements)
(append (ly:music-property note 'elements)
(list harm)))
note))
{ \artHarm ais }
BTW, this only works properly in absolute note mode due to the way
transposing interacts with \relative { } blocks (there's a note in the
docs warning about this under \transpose).
Cheers,
Neil
