It is a daily rebuilding of my trumpet technique. Anyone who would like to discuss this with me more, just say so. Also, I do not intend this to be an ad for my books. I make my living playing trumpet, not selling books. PS One thing I haven't mentioned is how important rest had become.

Playing trumpet with a lip buzz embouchure is a muscular action. How strong the lip muscles are dictates what kind of range and endurance you're going to have. You rest between phrases. You rest between practice sessions. You rest between days of playing.
