Hello, everyone! I'm having an issue where my throat is painfully clenching up whenever I play my trumpet. For some backing information: It's been a while since I've been serious about playing trumpet. I recently changed schools (I'm fourteen) and the band at my new school blows the last one out of the water, so much so that I made the extremely difficult descision to stop playing in the band. I recently have started playing trumpet again, as I will be using it in my Symphonic Death Metal band soon. Here's the thing. Whenever I play, anything above an Eflat causes my throat to clench up to the point of hurting. I don't know what to do about it, I somehow stopped it from happening back when I was playing in school, I need help in getting this to stop Thanks in advance.
