When I used to play clarinet in concert band at my previous high school, we played a piece, I don't remember the name, but it had something to do with American this or that. Amercian Faces, or something like that maybe. It had some combination 32nd and 64th notes runs in D major crossing the break and going up as far as high F# above the staff as far as I remember. They were just rips, not really in time, but ending on the right beat while still getting all the notes in was DEAD hard. And it was so fast, that if you weren't fast enough at the break, all the rest of the notes would just be that ever familiar SQUEEEEEK, so you had to be extra careful that didn't happen. My clarinet didn't have the best sealing pads, either, so it was quite a challenge.
Anybody know any challenging pieces for horn and trumpet that I could try out? I don't own any trumpet-specific music, but on horn I can play the Mozart concertos, the first Strauss concerto, and most of Morceau de Concert, an arrangement of a Saint-Saens violin concert piece. Unfortunately, that's the only horn-specific music I have. Since I don't have any horn exercises, I've been playing violin études by Kayser, Weiss, Wolfhart, Danca, Mazas, and de Beriot.

I transpose down some of the higher ones down to whatever key I feel like that day since I can't well play violin études in the seventh position on horn.... so it becomes a transposition exercise.
