for solo trumpet

I'm putting a little effort into something that I really should be putting a lot of effort into. It's a trumpet piece and my goal is to compose it somewhat visually, basing my pitch choices more on the way it fingers on the instrument than on anything else. E is 1st+2nd key, F is 1st key, F# is 2nd key, etc, so the alteration between these combinations is part of what makes the music.

I once spent a long time writing a piece like this for clarinet, and found it so boring that I gave up the whole conceit. LMK if you'd like to see it...
