Which mouthpiece should i use if i have large and puffy lips. Right now I am a ninth-grader who plays on a jupiter trumpet that i got in 5th grade. I have been using a 7c mouthpiece ever since i was in 5th grade and i was never able to play higher than the E right at the at the staff because my lips are too big.. Every time i play the trumpet and try to play higher than an E, i end up failing even if i am using as much air and airspeed as possible. The only way i can reach a G above the staff is by pressing my lips against the mouthpiece really hard, causing a ring to form on my lips and my lips to hurt.I was thinking of getting a Bach 3c or something close to that. What are your thoughts on this?
