I am a senior in High school in Texas. I have been looking into joining the marine corps band since my sophomore. I was a trumpet player, and a pretty good one if i do say so my self. However, I had to switch to Euphonium for an unknown reason, due to the fact that my embouchure did not respond with trumpet during marching band season of my Junior year. Luckily, I have not encountered any problems with Euphonium so far. I do make progress very slowly, and i have a good high G, not great, but good. I am wondering if you had any advice in what repetoire i could play that does not require too much range. Also any help on range improvement.

Thank you for your time
