⌂ Moving notes or chords in collisions horizontally using the force-hshift property

You can manually determine the horizontal shift of a note or a chord when it collides with notes in other voices, using the NoteColumn #'force-hshift property. Overriding this property will appropriately move all objects associated with the note or chord—that is, the stem with all its noteheads, ledger lines, augmentation dots and beams.

Note that this technique will only work when the notehead collides with noteheads in other voices, and has no effect in monophonic situations.
