After playing on Monette mouthpieces since last June, I've become interested in the "whole body concept" of trumpet playing. I'm sure that it is about time, since I've been playing trumpet for 43 years. I'm going to a seminar at the local health food store this afternoon about Alexander technique for singers and musicians(really, that's what it is posted as......singers AND musicians). I'll bring my horn and try to volunteer as an example in need of help. Anyone out there use this method? Is it common sense, or do I have to think about this while playing?
