Hello everyone, I've just run into another obstacle in my trumpet playing. When i start to play an etude or any kind of playing, my neck becomes all tense and my diaphragm clenches to push out air. I can complete a phrase without two breaths. I'm starting to loose my range too! Hitting a G above scale is becoming very hard. I have braces....if that matters (I'm using BraceGuard) Anyone have any suggestions? I've got jazz auditions in a month, and the audition comes out in a few days, and as a player already in the top band in the school, i'm expected to produce... So, I'm looking to not experiment and start with right practice techniques so i can ace this audition. Thanks for any help guys.
