The correct way is the Herbert L. Clarke, Claude Gordon, and William Knevitt way. Everything written in my posts is consistent with their teachings.Are you saying that constricting and opening the mouth cavity BEFORE the air even reaches the lips is a good thing? Because this is what you're advocating. The syllable technique is kind of like putting a kink in a garden hose. Except that you won't really do this at all anyway. In order to actually speed up the air to play the upper tones as you've described you'd need to make a perfect seal with tongue between the upper teeth. Doable but very difficult. And a waste of good energy.
"All your muscles"? Aren't the abdominal muscles which put air through the instrument required?
Please explain how Bud Brisbois played well articulated Triple C's while using more lower lip than upper. Explain how this kind of advice could "benefit" someone predisposed to using more lower lip.
This is consistent with your advice so far. Which has, essentially thrown physical law at the window. As if by playing the trumpet we become immune to the effects of gravity, dimension, mass, volume etc....
Explain please my very solid High A (above High C) yet I'm not playing pedals much at all these days. Nor back when i did was much able to play them without using alternate fingerings.
Explain how you and the system you advocate are capable of knowing the "correct practicing" technique.
