Help me please. I'm in a bad way. This year half time show is a killer. It is all nearly scream parts for 1st trumpet and I'm seriously have endurance issues from the middle of the third song through the fourth to the end. It's killing chops on top of that. I can barely play at all after practice in the evenings. It's getting on my nerves. Our lead trumpet yells at me everytime I drop out to take a second. And our third chair player doesn't play full enough to sustain if two people drop out (me for a moment with the mouthpiece away from the lips, the lead player to yell when I take my moment). Plus, our sectionals are held on Mondays before practice and our "section leader's" (who happens to be our lead player) idea of building up endurance is making us play screaming passages over and over again while he sits back and listens to us force our way through it. Then he complains we drop out and are lazy. We have no chops left because of his twisted idea of building endurance. So, anybody has some exercises I can do to increase endurance and help be able to withstand our "sectionals" if you can call blowing your brains out on command a sectional or even practice. Sorry, I'm bitter.
