Adventures with 'other' instruments...
Ex-brass player here! I majored in euphonium and minored in piano in undergrad (was a music education major), and played for several years after graduating. Once I left music ed as a profession, I moved toward instruments that were more fun as a solo player -- piano, uke, autoharp, and now dulcimer. I still love my wind band and brass band music, though, and I still have a lot of connections in the brass world!
If you like folk music on brass, check out Percy Grainger, Gustav Holst, Vaughan Williams, Malcolm Arnold, Edward Gregson, and Philip Sparke. They're the kings of British brass band and folk music!!
