Ok so heres the thing, next year i'm auditioning for the high school all star band for kent state university, and I don't have anything to audition with. I know its a long time away, and school just ended but I would like to get started, last year I wasn't completely prepared, and I didn't do so well on my audition. So if you know of any please tell me.

If you didn't know already I play the euphonium, and thats what i'm auditioning with.
