Our choirmaster is an early music fan (he took his master's at Oregon, which is Early Music Central) and he's determined to have us sing a complete DuFay Mass someday . . . if you're used to singing modern music the early stuff will throw you for a loop. The harmonies and everything are SO different. And it sounds strange to modern ears - strange but beautiful.
Thanks for turning me on to du Fay. I’d never heard of him before (being generally more into Guns n’ Roses than Guillame du Fay) but his work is really beautiful.
