Matthew's Journal

Is there a standard warm-up / set of warm-ups for singers? I mean more for a group than for an individual.

I know how I like to warm up, but I think I'm rather odd. When I've directed choirs in the past, I've just sort of made something up (scales, some easy music with lots of good vowel sounds, that sort of thing), but presumably someone has thought about this in a more systematic way?
