Up to this point the highest note I've had to play is a concert E above the staff in Ferde GrofĂ©'s Grand Canyon Suite. Well, as of yesterday the bar, for me, was raised during rehearsal. We played a new piece called "Wade in de Water" and I'm sorry I don't remember the composer's name just now. I'll post it tomorrow or something.
It's for baritone and orchestra, kind of an American spiritual piece, Anyways, the end is the solo trumpet wailing away with a plunger in a quasi candenza that ends the piece on a high concert F. It's written for C trumpet. The F lasts for two slow measures in 6/4. It's a well written piece, very passionate.
It was premiered, I'm almost positive, by our own Eric Berlin with the Albany Symphony under D.A. Miller conducting.
Forget about using piccolo. It wouldn't work well, given the style.
