At the end of August I will have been playing trumpet for 5 years. I can play up to high C, and I have been told I have a great tone. I practice when I can for about 30 min to 1 hour. I don't have a private teacher but my band director plays trumpet and I have been trying to learn everything I can from him and everyone in the trumpet line. I am a freshman in high school and I'm 6th out of 13 trumpets. Where should my level of playing be? How can I improve? I practice scales, cromatics, arpagios, lip slurs, tounging, and long tones. Does anyone have any advice?
