Hi Manny and welcome back, A while back I posted about changing the way I play so I can play lower on the pitch. I have it mastered now. Every time I pull out the trumpet I check my pitch with a tuning fork and I'm right there. The new problem is that I feel like I'm beating up my lower lip. This is new for me and I don't have the endurance that I did. I expect the endurance will come back but last night while I was playing I could feel my lip really getting sore. Any ideas?
