That makes perfect sense. I do think, however, that to a certain degree this can apply to notes within the staff as well, especially in such a vertically tight context such as this. That's the reason I prefer OCTO's version even over my own. If you break the tie for the notehead, the interference with noteheads and accidentals (which does convey pitch information after all) is reduced. If the tie is moved above the notes, all interference is eliminated, and as I've said, I don't really think the tie could be mistaken for a slur in this case.John Ruggero wrote: For me, a tie among ledger lines obscures the pitch of the note, while one through an accidental would rarely do that.
I'm certain I've seen this kind of vertical tie displacement several times before. Unfortunately I can't remember where at the moment, but I'll try to find a reference.
