Hi Harm, Oh no! I winced when I read that... My apologies and thank you for your patience with my rookie mistake(s). I'm still getting used to typical scheme formatting (for closing brackets), and this is twice now that I've let editing code after pasting it into an email get the best of me (ironically, in an attempt to communicate more clearly). So no more of that, and I will make sure to double check in the future. > Nevertheless, I can't explain why your code doesn't work. > Speculating, I'd say 'X-offset and 'X-extent are the wrong properties > with 'before-line-breaking. > Using 'extra-spacing-width and ly:grob-translate-axis! for offset in > X-axis seems to work: > > \version "2.16.1" > > CustomNoteHeads = > #(lambda (grob) > (let* ( > (notecol (ly:grob-parent grob X)) > (rel-coord (ly:grob-relative-coordinate grob notecol 0))) > > (ly:grob-set-property! grob 'extra-spacing-width '(-1 . 1)) > (ly:grob-translate-axis! grob 1.251178 X))) > > \score { > \new Staff > \with { > \override NoteHead #'before-line-breaking = \CustomNoteHeads > } > { c' d' e' f' } > \layout { } > } Thanks for the tip on these other ways to get the same results. > But there _is_ something strange with 'X-offset in chords. > In the examples below _none_ of the tweaks work.

Well, I'm glad I haven't sounded a false alarm in my effort to help. It did seem like a bug, although an obscure and probably not very consequential one.
