I am currently in high school, and I play in my school band, orchestra, and jazz band. As of this year, I am the lead trumpet, so I have been spending a lot of time trying to expand my range on my horn. I have been pretty successful so far, and I've gone from being unsure on Ds above the staff to playing F#s now. When I first started working on my range primarily, my tone became extremely bright, even on low notes. I've tried to balance my practice routine with more of my exercises in the low ranges as well, and now I can play with a darker sound when I try to on most notes. My tone cuts a lot now though, and I have always been loud as a player. This is great for my Jazz band, but I still have to focus on orchestral, band, and solo work. I am really happy with my mouthpiece and my trumpet (I play a Conn Vintage One and a CKB 1 1/2 C mouthpiece, so its not a small or shallow one either), and I'm not looking to change either right now. What kind of exercises can I do to increase my versatility, both high and low? I'm really looking for the ability to play dark tones throughout my range without losing the ability to cut when I need to.
