I was messing around with buzzing ( no mp) and noticed my air stream seemed to point down not straight . So then I tried it with the mouthpiece and played with it until I could feel the air stream increase. In order to do that I either had to move my jaw forward or play around with my lip position.
Then I started thinking.. what the heck am I doing this for. The buzz is sort of a feedback thing right?
Anyway.. your thoughts?
