With my current embouchure, I placed the mouthpiece too much to the right too low on my lip. I would use my top lip for vibration and would tighten my bottom lip and curl it into my mouth. The bottom of the mouthpiece would lie one centimeter below my lower lip and the top would lie in the middle of my upper lip. As a result, I have had really big endurance issues, a really small sound due to the fact that I use my upper lip to vibrate, and other really messed up stuff. My teeth are also different from most people. When most people clench their teeth, the bottom row of teeth is usually more into the mouth than the top row. When I clench my teeth, they are even and come down together perfectly. In order to get a new embouchure, I'm currently trying to center the mp and get both my bottom lip and upper lip into the mp 50/50 so that there can be better vibrations and I won't have that many endurance issues. Can people offer me their advice and help, because I don't think this feels hopeful for me or if I can continue playing the trumpet.
