I'm working on a piece where I want a brass quintet (trumpets, bones, tuba) to sound like crumhorns. Actually sextet: I'll double the bass trombone (lowest part) with tuba occasionally. For those who don't know crumhorns (Krummhorn means crooked horn in German), they're wooden, J-shaped, capped, double-reed instruments of the Renaissance that sound like a mellow kazoo.
Two questions: 1) how to do this with a real [modern] orchestra, and 2) how best to simulate it in GPO?
1) Would the Harmon (buzz-wah) mute work? Or maybe this mute together with flutter-tongueing? If the latter, how long can the trumpet/trombone/ bass trombone/tuba player sustain the flutter technique? Are passages of between 15-30 seconds feasible? Values are mostly 8ths and qters, some 16ths, in moderately quick tempo, qtr=90. I played cornet and trombone in high school band, but that was way before the Renaissance, LOL, and I don't remember using flutter tongue.
2) Right now I'm using trumpet/trombone, straight mute PLA1 patches. There is no flutter tongue in GPO brasses, correct? And no mute for bass trombone or tuba? Right now the tuba overpowers the muted ensemble and the timbre isn't right. How do I get those suckers to buzzzzzzz?
