I'll try to keep this as short and clear as possible... In high school I was surrrounded by very good players and I had to find a niche, which happened to be high notes. I spent all my efforts pushing my range and volume, switching up mouthpieces (Jet tone Al Hirt, to Schilke 14A4a, to Schilke 6A4a) and doing all the tricks I could find like curling the lips etc etc. I kept playing like this through College and with some paying groups. They were all Big/Swing band groups. I avoided concert playing like the plague. I found after time that my intonation was slowly going to crap and I couldn't even play a scale through two octaves without having to change my lip position. Also, I got really tired after playing a solo. So that was all about 5 years ago when I stopped. I am now trying to play again and a friend of Claude Gordon got me a CG personal mouthpiece and a Herbert Clarke book to get back into the groove. The question is, other than smart praticing, should I use my old equipment (Schilke MP) or stick with the deeper piece? Or should I just run through my stable of mouthpieces to see what I sound "best" on. Currently I have VB 11 1/2C, Schilke 6A4a/14A4a, DW 1.5C Heavy top, VB 7C.
