The soap bubble demo! Here it is.
YouTube - On Breathing for Trumpet
In reviewing this I am disappointed I wasn't clearer when saying the air was moving through the horn slowly. "My bad!" What I meant to say was that the FLOW RATE in liters per second is relatively low. OBVIOUSLY AIR SPEED in meters per second, varies along the length of the horn, the slowest point being at the bell. I just thought the soap bubble is fun here in the context of the discussion.
In this clip I talk about tongue position which is critical to the way I play. I don't talk about fast air, though I allude to controlling air flow. I don't honestly have a better way of describing it, as I am still sorting it all out.
YouTube - Flexibility and Trills
I honestly believe tongue position is important. However, in the context of this discussion, I can't properly explain why, yet. I'll keep an eye on this thread as we are homing in on some great ideas.
