Re: [HELP] Change notehead font-size depending on note duration

[Valentin Petzel]

Hello Robert,

the problem here is that the font-size property of the NoteHead is not 
evaluated. (This happens from time to time, and I’m not sure why this is so.)

To get your callback working you can ensure that the font-size is calculated 
by doing something like

    \override NoteHead.stencil =
    #(lambda (grob)
       (ly:grob-property grob 'font-size)
       (ly:note-head::print grob))

(the grob-property effectively just forces Lilypond to calculate the value).

Cheers,
Valentin
