In a harp part, I have a C3 grace note to an A#4-B4 chord. The C3 appeared initially in the space under 4 ledger lines below the treble staff. I want that to appear in the bass staff to suggest left hand, so I selected it and pressed M to move it. It looks fine, but there is also a whole rest in the measure. It’s not a big deal, but how can I make Dorico hide the whole rest on that measure alone?
In harp music it seems that the two staves are conceptually like one even more than in keyboard music.
This works! But after struggling valiantly over this triviality, I made an editorial decision to leave the grace note on a ledger line. At least I learned something in the process. Thanks very much for that suggestion that never occurred to me.
