Hello Aaron,
Thank you for your help. That does make sense to me and works out quite
well -- I don't yet have a grasp how various commands and settings are
actually working in LilyPond. I found another example in the LilyPond
documentation that shows the internal representation. Where do I find this
for input I want to inspect further?
http://lilypond.org/doc/v2.20/Documentation/extending/doubling-a-note-with-slurs-_0028example_0029
I tested your syllable function with tweaks (like changing a notehead to a
quilisma), and expressive marks like a tenuto. It appears the current code
doesn't handle them (this is getting into advanced territory much more
quickly than I expected).
Sample input I attempted: \syllable { a' \noteQuilisma c'' b'_\tenuto }
where
noteQuilisma =
#(define-music-function (note) (ly:music?)
#{
\tweak NoteHead.stencil #ly:text-interface::print
\tweak NoteHead.text \markup {
\scale #'(0.24 . 0.24)
\override #'(filled . #t)
\path #0.0 #quilismaPathGreciliae
}
\tweak NoteHead.X-offset #0
\tweak Stem.stencil ##f
#note
#}
)
Many thanks,
mattfong
