I have a question and I wasn't sure if it would fit into any of the other forums, so here it is. I've been playing trumpet for about 6 years, and recently I've noticed that when I play my mouth piece is far off center, about 1/2 of the way between the center of my mouth and the right corner of my mouth. I know that this is incredibly limiting to me because my muscles on the different sides of my face grow at different paces. This limits my high note range as well as my stamina for when I'm playing. In short, does anyone know any exercises or methods that I can use so that I can learn how to recenter my trumpet when I play?
