Being new to the trumpet, I am still looking for the embouchure that works for me. I recently think I've finally found what fits my teeth/lips- and that is with slightly more top lip, with the mouthpiece "anchored" on the bottom lip and tending to tilt the trumpet downward somewhat. I believe this is what would be considered "upstream," although I am still not sure what the difference between downstream and upstream. Incidentally, that night I found trumpetteacher.net, and Jeff Smiley's "Balanced Embouchure." Since what he described seems to be something that I had already been discovering useful on my own, I'm interested in his book now. So I supposed I actually have three questions: 1. Does the embouchure I have started to find comfortable and useful seem sound from what I have described? 2. What is this "upstream" and "downstream" style? 3. Has anyone heard of this Balanced Embouchure book, and is it a decent one? I'm a little skeptical since his site makes it seem so sensational, I just want to make sure it's not a gimmick/scam before looking for it at the library or bookstore. Thanks for taking the time to answer!
