While I admire Charlie’s playing, I’ve learned that for me, this kind of thinking and suggestion of “buzzing tightness” or a “buzzing set” can be disastrous. For me, the amount of tension required to lip buzz when doing a “peel off” is considerably more than producing a note on the horn. I can’t imagine setting myself up to play that way. I have experimented with lip and mpc buzzing in effort to become more efficient and encourage a more focused set. I easily cross the line between benefits, and sound and flexibility consequences, which I’m experiencing now. Ultimately, it’s my responsibility to figure out what works for me. Greg’s approach and concepts make more and more sense with time and practice.
