I was nominated by my band director to try out for some honors band at this college and I`m worried about the auditions. Anyone have some advice from experience or whatever in how I can prepare ability-wise and perhaps emotionally?

Make sure to be well rested two days prior to the audition. Drink plenty of water. Eat a bannana, before hand, it is said to help calm nerves. (Who know if it really does or not?)

Know the music well enought so if you were to loose your place you could still keep on playing.

Play in front of as many people as you can before hand.
