Today was solo and ensemble, and seeing as i didnt do so well i am looking for some sheet music to start on for next year. I am currently in 9th grade. Any ideas? or should i just go to a music store and look around?

it depends on how good you are at the clarinet. why dont you just look for stuff here?

The only problem with noteflight is that you will need to get permission from the composer of the work (whether it is copyrighted or not) to perform this piece. Also, you will need to upgrade to "crescendo" a costly $50 a year (it's just a better version of noteflight) to isolate piano/clarinet parts. However, it is still an option. I would suggest trying some of these pieces:

Schumann Romances for Clarinet
A Piano/Clarinet orchestration of a Mozart clarinet concerto
A "Weber" piece

You could also ask a professional. I am not a clarinetist, so their input will probably be more helpful.

You'll also probably have an advantage if you play a famous piece. The judges may be puzzled if you a play a piece by some budding composer on noteflight who no one has ever heard of and probably doesn't know the instrument that they are writing for as well the masters. Stick with them!
