Oh, at 16 years of age, I thought I was amazing. I had fast, furious technique. High Range that made all my section mates jealous. When I got to college, it was an eye-opening experience. That's when I realized I couldn't read music worth a darn. I had a horrible time counting and reading complex rhythmic patterns. ..and if someone asked me to play something, I never knew what to play: Arbans exercises? Super fast Clark? Claude Gordon high note routines?
The lesson is that we sound how we practice. If we spend all our time practicing exercises instead of music, we will be great at everything but music. My trumpet teacher thought I was terrific, but he assumed too much that I could just be a musician just because I practiced all the technique.
I'm not a trumpet teacher, but I would love to give lessons to kids your age. I feel that I have lots to offer from my own experience. 16 years old seems like yesterday to me. I'm 48 now. Play music and make it sound beautiful whatever it is that you're playing.
Best of luck, and just remember - be a musician, first and foremost.
