I agree that conceptualization and visualization can help - I was shown some things at one point by a pro lead player that served to make my life a lot easier on a gig - stuff that originated with Don Jacoby. Anyhoo...Here is the bulk of what I sent. Keep in mind, I sent this stuff along because as mostly a self-taught player (meaning I haven't had a lot of lessons - I just keep my eyes and ears open, and I've been fortunate to have been in a position to gig with a lot of really fine players) these are things I have developed on my own over 25+ years of playing this hunk of metal that worked for me. Feel free to pick and criticize, but it works for me, and I think it would help a lot of other kids who have some chops issues due to a lack of focus, strength or development with their chops. One thing I should have added is the importance to clarity of sound with all of that. I have found in my own practice that once things start to focus and the mouthpiece pressure reduces, the sound rounds out and becomes more dense and opaque. The "meat pillows" idea would be a helpful visualization there. I also just realized I forgot to talk about scales, but that was more of just a knowledge thing - I play through all of my major and minor scales in the circle of 5ths as part of my warm-up. This also was only meant as a beginning Ok - hack away.
