My high school band director tells me that my sound is fuzzy. I have heard it in other trumpet player's tones. Not much note. Just a lot of air. It's more air-y than anything. Could any of you point me in the right way as far as embouchure tips or helping to solve this conundrum? I also feel like as I am playing high notes, I tend to smash my lips into the mouthpiece. How do I keep my lips farther away from the mouthpiece to keep from going sharp and getting that "Ring" around my lips every time I play?
