Hello experts of TM. I am 14, started band in 6th grade. Moved on to 7th and now I am in 8th. I just had my UIL (University Interscholastic League) performance today along with sight reading and we got all 1's which is the best score. I've been in the top band at my school for 2 years after my beginning band year. Although I just started and I am only 14 I take band and my trumpet very seriously. I begin fixing errors the moment I notice them, whether it's bad tone on a whole note or the habbit of playing too tight on high notes. This one particular problem has not been able to go away. I get a little nervous when I play alone in front of the entire band. I do this each day so the director can tune me with a tuner. I play a whole note concert F. For some reason I get a little nervous and shaky and my jaw will do vibrato. Ive tried to stop but it has been difficult. Any suggestion is appreaciated. Thanks p.s. I am first chair and I dont want to make myself look like a fool thats afraid of playing a whole note.
