Hey, guys and gals. I've not been in an organized group in awhile and my gigs are mostly honor guard related, ie Taps and National Anthem. I'm not playing in front of people more than 5 or 6 times each month. The rest of my playing is solely practice.........scales, tonguing exercises, and technical work. Does anyone have some suggestions on how to help build my upper register? I've played most of my life on a Bach 5B or 7C mouthpiece (high school and college). These mouthpieces have not been really helpful in facilitating higher notes. I've recently added a Bach 3C and a 7D. My stamina is better with a 3C and my upper register is greatly enhanced with the 7D. What are your suggestions? What kind of drills do you practice and/or how much do you rely solely on the mouthpiece for upper register work?
