Hello,
I want to write a before-line-breaking callback for stem and need the
staff-position of the associated NoteHead. (There aren’t going to be
any chords.) This
%%%%%
\version "2.19.35"
{
\override Stem.before-line-breaking =
#(lambda (grob) (format #t "~a\n"
(ly:grob-parent grob 0)))
b'4
}
%%%%%
tells me that the parent is the NoteColumn. How do I retrieve the
NoteHead from the Column?
TIA, Simon
