It seems that practicing with an ultra small mouthpiece(Kelly Screamer) effects my embouchure. It seems to have less tolerance in several areas, including: horn angle, centering, and air flow, pressure on the lips. Also I can feel many smaller muscles getting a work out. These habits: horn angle, centering and air flow control seem to be beneficial to other mouthpieces. In other words I feel that was able to get by with a poorer technique on the larger mouthpieces. Has anyone else had a similar experience?
