Hey Manny, I have a huge problem. A week ago my high school started band camp. We have an extremely challenging show in store, pushing the first trumpets to our range limits. Unfortumately, it seems that I have lost my range. The first day, I came in with a high E range, playing the first day with ease. My lips were tired after the first day, however, and so I decided to take the music down the next day. Now its the second week, and I can barely play a high Bb. I'm playing the exact same way that I played all summer and on the first day, but now the high Bb is coming out fuzzy. I'm trying not to put pressure on my lips, but it isn't coming out. I'm playing on a Bach 3C mouthpiece. Do you have any advice Manny? And BTW Manny, I hope you had a great time on your trip.
