Hi David,

overriding 'before-line-breaking returns the NoteColumn as X-parent of Script:

\once \override Score.Script #'before-line-breaking =
  #(lambda (grob)
     (let* ((nc (ly:grob-parent grob X))
            (nh (ly:grob-array->list (ly:grob-object nc 'note-heads))))

       (newline)(display "nc---------- ")(display nc)
       (set! (ly:grob-parent grob X)
             (car nh))))

log:
GNU LilyPond 2.15.39
Processing `splayed-stems-post.ly'
Parsing...
Interpreting music...
Preprocessing graphical objects...
nc---------- #<Grob NoteColumn >
...

so I didn't rethink it.

The approach via 'after-line-breaking works!


Many thanks,
