My band director doesn't have a clue about the problems I'm going through right now and, frankly, I don't want to explain them to him. He's also a (very good) trumpet player and tends to be really harsh and demanding on the trumpet players he has. I've talked to him before about other mechanics related issues and had taken private lessons from him two summers ago (that I neglected to mention in my original post) and he was no help whatsoever.
I don't know what school you went to, kcmt01, but there is only one band class at our school and it has about 25 people in it and 3 trumpets (including me). Many kids drop the class over the years due to this band director's bad attitude and lack of responsibility. Music in general has been going downhill at my school every year due to his, dare I say, immaturity, since he is the one person teaching everything from choir to orchestra to wind ensemble to jazz band.
