Auditions and Bewilderment

You're now reading the blog of a musically-doomed man.
I play trumpet in the University Band up here and we had auditions today so that the director could place us in what he deems to be our proper chairs. All eight of us trumpeters were given the audition piece on Wednesday. Last night I practiced with a good friend of mine who's also in the band until we felt comfortable with the piece, and that was it. Today we were lined up outside the band room and taken to a "secret location" around the corner that was open so everyone in the building could hear your audition. My nerves were through the roof. For those of you who know me well enough, this is typical.
After a few minutes of tense waiting and pacing, I was up. Everyone before me sounded so good! I consigned myself to just play and go straight to 3rd chair; dead last. A little chit-chat was made with the director which didn't help things at all. As I was playing I was sure the director was bracing himself to catch my shaking body which probably looked like it could crumple to the ground at any moment. I began by missing the first note several times. He suggested a different part of the piece, which I promptly fumbled over. Finally, I told him that I had practiced the part he marked out and I was going to hit the note this time, just he wait and see. I did it, sprinted through it, and trudged back to the band room. I butchered it, big-time.
One other trumpet played after me and then the director came back to give us our new positions. I was blind-sided by "1st" chair and SOLO! I couldn't believe my ears. I was dumbfounded.
So here I am, first chair after not having regularly played my trumpet in 4 years, 2 of those years being on a mission (meaning NO playing). I know where my weekends are going to be: the practice rooms at the music building. Okay, so it's not going to be as bad as I'm making it out to be, but I'm still nervous about being in this position and think that there are 7 other trumpeters who could fill this better than I can. However, I guess I can trust my director knows what he's doing and he put me where I am for a reason. I'll just keep my fingers crossed...
