This year in marching band, were playing a Motown era show. One of the numbers is "Lets Groove" by Earth Wind and Fire. Its great, but as a sophomore in high school playing 1st trumpet, it kinda hard to play over the staff the entire show. My range is basically up to the high C. Now, I've been playing this on my bach 3c (I also have a laskey 60mc that came with the trumpet I have now), and I'm wondering if a smaller lead style mouthpiece would help, or what would help me with endurance in the upper register. Again, this show is basically a lead piece, including a gliss from middle D to D above high C. And because its marching band, the show dictates forte basically the whole time. Any Ideas would be awesome. EDIT: I can hit the high D, but I dont really own anything above high C... I've been able to play the solo, but not really during the show. Before band camp I pretty much owned it, and could also play the E, but my endurance still sucked.
