Firs tof all I would like to thank everyone that reads this. Alright I seem to be playing really sharp. This problem started when I got my braces the very end of my freshman year. So im pretty sure the problem is related to that. im not at the beggining of my junior year and practice everyday but I have noticed that I have improved in every category except tunning. Even tone has gotten way way better even before I had my braced on but everything is so sharp. I have to play with a lot of bottom lip. So im sondering if this is braces related my private teacher doesn't know and my band director says that its most likely related to braces. Is it or is it just an air flow problem.
