I'm in my junior year of high school and marching band. I can honestly say that I have grown as a trumpeter (may have been a result of consistant practicing). However, my neck/throat feels achy when I play, and when I'm not playing. I know how to breathe from the bottom up, and I do it naturally, but my neck still feels achy. I don't think that I'm pushing the mouthpiece against my lips and tensing up, but I do get out of breath with show run-throughs. Also, how might I increase endurance and get used to that out of breath feeling? I play the second trumpet part in marching band and it isn't too demanding. However for most of the first song there are constant staccato eighth notes, The highest note I have to play is an A, which is at least a half note, in the fourth and final song. Playing at a stand-still is no problem, but marching, even though easier than last year is another issue.
