One of the songs in church this morning had a phrase about peoples and languages in harmony. Thinking of Gilbert and Sullivan's trios with different songs harmonizing, I wondered how difficult it would be to write a work (e.g. a quintet) of different languages singing at the same time. Somebody has probably done something like this before with two languages, though I don't have the breadth of experience to guess who. I'm curious how this could be made beautiful(*) with more than two or three. Anybody know?
(*) I don't find Aaron Copeland's blendings all that beautiful. Maybe that's my loss.
