overtone singing

What is overtone singing? If you've ever heard Tibetan Buddhist chant you'll know. But here's a short, helpful tutorial.

Basically the tongue (and lips and so on) in this type of singing changes the overtones that are produced while on a constant fundamental pitch producing a "bagpipe" type sound -- i.e. a high changing melody over a low drone. For some examples on Amazing Grace:

This ties in to the post on subtractive synthesis, and makes clear that there's a lot more going on when one pitch is sounded than one commonly thinks.
