Hi everyone. I have this delima.I"ve listened to advise about mouthpeices and for the most part, the advise I'e heard is good. But,. this is whats going on. By my reading and all, most players like and use something like a bach 3c, so I bought one. I love it because it sounds really good and it seems to have great "response" if you will. But here is my problem. I cant hit notes well. Ok. So I go another route and I buy a bach 10c which is a whole lot smaller. I can all notes the I should be doing, I mean it really imjproved my playing but the sound is a little airy and when I come down off of high notes like "high c" cause I like the upper register and I am trying to improve my range, I cant play notes below low c. Does that make sense. I like the way the 3c sounds but I cant play it well. I know that I will be looking for another mouthpeice shortly. Does anyone have any suggestions.
