Hello,
I'm trying to do some cross-staff beams in the middle of a piano staff.
They seem to work pretty well, but I think the beaming is wrong.
In beat 2, the 6-tuplet starts in the right-hand. I don't have the
Kurt Stone book on modern notation in front of me, but if I remember
correctly, the staff of the first note sets the reference for the beams.
That would mean the a-sharp 32nd-note should connect at the bottom beam,
not the top one. Same for the subdivided beam in beat 3.
Is this right? If so, is there a way to correct this? Or is there a better
way to create cross-staff beams?
Thanks,
Jonathan
