I was at my lesson today and I mentioned to my private teacher that I've been wondering if an embouchure change would be beneficial to my playing, or possibly necessary. I've gradually been moving the mouthpiece lower and its gotten to the point where I barely use any upper lip. I get enough lip to create a vibration but that's it. I'm not sure how I've been able to produce a good tone with my current set up. What we've decided is after a jazz festival this Saturday I will switch down to the third or fourth part in jazz band and the third part in concert band so that range won't be a big necessity for the time being. My private teacher wants me to start working on forming the embouchure, put the mouthpiece on the lips, and blowing without articulating. Before I was playing with a very open embouchure, so now we are trying to get my lips to stay together while buzzing. I won't see him again until next Tuesday which is when I'm planning on starting my change, but I was wondering what to expect. He was saying that I should be back to my normal playing within 6-12 months but it varies from person to person. I'm not in any rush to get it fixed because I want to make sure it is correct this time, but I was wondering how long others have taken. Since I know some people will say that I should leave it alone, he's not the only one who agrees it needs to be fixed. I talked to Dr. Tim DeWitt who teaches at the college I want to go to and he agreed that it is a good idea. He said that if I'd come up next year he would probably want to change it then so doing it now is a good idea. Anyone know any tips that could help with making this transition as easy as possible?
