Thanks for all the replies
I am an airhead

I found all the information on the site (during class the other day I spaced out on the lecture and eventually found it.)
It's a $50 membership fee. Which is reasonable. I think I'm going to try out for the Premier Orchestra. I figure I might as well just go for it. The Classic Orchestra Requirements seem like a piece of cake. And I play well enough for the Academic Orchestra Requirements. So I figured I might as well give it a shot. There's still 11 weeks untill auditions, I have time.
I looked up both solo pieces: Haddad - Suite for Tuba and Hartley - Suite for Tuba. Pretty scary stuff. But I can do it. I plan to order both pieces before choosing which one to play.
I've only auditioned for the Sierra College Honor Band. And that was a tape audition. I managed to make it in. I got first chair of the 4 tubas. I was shocked

. When he asked us to tune, we all looked at each other. Then he said my name and I had a mini heart attack

. Although it was only for 2 days, that was the best group I have ever played with. We sounded AHmazing. And It's because of this, I want to move more towards audition only bands.
I still have quite a bit of time to think about it. But untill then, it's just going to be even more practice! I am one of the band geeks that is ALLways in the band room. It's my second home. I practice non-stop. So the next step is learn those pieces. I guess by scales and long notes to increase my range.
Thanks

I don't play the tuba.
I am a tuba player.
There's a difference.
