Al, there are several "lead techniques". Erik Veldkamp has spoken about his "wedge" technique and there are other players also turned on by this successful method. It is a more "physical" way of breathing/playing. That is why the universal relaxed is perhaps not universal. I learned something a while back that I would like to share here. The diaphragm is there for the INTAKE of air. It has no possibility to "push" air. Check this picture out and you will see why: Diaphragm Breathing The diaphragm contracts to draw air in and relaxes to let the lungs release air. If you are "pushing" it ain't the diaphragm!
