Hey everyone, Recently, as I've stated in a new thread, I was sitting in a practice room, one without a window, ironically, and began looking back on some fun times I've had with my friends at college, and remembered a tale one told of a young student he knew who could play the trumpet without a mouthpiece in the pipe - not well, but the notes would speak. So, I figured since I needed to warm down and work on my breathing, why not? I took the mouthpiece out and put the tiny hole up to my lips, and nothing happened, couldn't get it to sound. Rather than forcing the hole against my lips, I slid the opening of my Strad's leadpipe in my mouth like a straw and kind of "puckered" the inside of my lips, blew more, and voila, it spoke. Meanwhile, I'm keeping an emphasis to put as little pressure as possible - I don't want a hole in my lip, or to see blood spurt out as Armstrong is told of having done (though I'm aware of his playing style embouchure wise). I managed to get a very flat C, or concert Bb if you wish to call it that. I experimented and could get low F#, and a D above that low C, but little more. My lips didn't hurt, so I threw the mouthpiece back on and man, full air/support/deep and dark sound all the way, and my multiple tonguing improved too. I warmed down by trying to work on intonation down low, playing a note on the piano and pressing the pedal, then tuning with my ear and checking the tuner. That ended that, and was about three days ago. Now, it's made my sound much nicer, probably by helping me learn how to use the air appropriately, and I can play from that low F# up to middle line C. However, I'd like to know if anyone else knows of the effects of this or has tried it or teaches it? I want to know if I'm hurting my lips/embouchure by doing this without knowing, though I think it's strengthening the back muscles of my lips and forcing my embouchure to get stronger since it'll have to hold a smaller hole than it's used to from a Bach 3C. I approached my teacher about it, but he'd never heard of it or thought of doing so, and ended with, "Well, let me know how it goes." So, any thoughts, comments, criticisms?
