So, I've posted before about my problems with playing, specifically my problem with endurance and getting a "double buzz". Also, I've posted before about how I thought I used to cheat in college because I would pull my mouthpiece down a little bit in order to play higher. Well guess what! I wasn't cheating!!! Turns out that since I've been working on the solution from the other end I've kept the mouthpiece too high for my lips to handle the full register. I've been pulling the mouthpiece back down and presto... double endurance and no double buzz, plus immediate range extension. I have a good sound in all registers now! I guess the reason I had thought I was cheating before was because I had never really worked on the full register of the horn with the mouthpiece pulled down before (it just felt funky). Well, it still feels a little funky, because I haven't played like this for long, but the sound is good and most of my problems have disappeared... most. I won't get into what's left, besides the many years of work.
