I'm not a brass instrument player, but I'm a retired saxophone and flute player. My involvement in band from age 9 has caused me to want some continued connection with wind instruments. As a result, I play Native American Flute(s) now.

Are there any other brass instrument players out there? I've played the trumpet on and off since I was 12. One interest of mine, as a hardwired experimentalist, is trying to figure out jazz/classical tunes on dulcimer and folk tunes on trumpet. I'm not great at it, and it's probably not for everybody, but it's alot of fun, and I actually get some pretty cool results every once in a while.
