I've been playing a lot lately. Tonight my chops are tired, especially my top lip. I think I will put the horn away until tomorrow. One question (because what good would a thread be without a question), should the tiredness be more evenly spread out between the top and bottom lips? When I play I really feel the vibration from my top lip and I can feel that part of my lip now. Should I be looking at my technique? I hope this makes sense.
