Hi, i'm in highschool and i'm auditioning for the all-state band in a few weeks. The solo i have to prepare is the Haydn trumpet Concerto movements 1 and 2. Im having a lot of trouble with the range on this piece. Its frustrating because i know i can play every bit of that piece with no problem, but i just dont have the endurance to link it all together. I have been practicing steadily for two months on this piece, but the audition is in two weeks and I still can't play the whole piece in one shot. Are there any tips (besides years of practice) that can help me with this piece? I'm desparate at this point. I've been practicing for at least an hour a day for the last month and i've had barely any improvement on my endurance. If it makes any difference, i am currently using a bach 5c on a Getzen 900 (the new one).
