Hello All -

I am part of a group of folks who work in the world of ethnic flutes, and in particular the origins of these instruments. We're
trying to track down a potential link with yucca stalks.

We have examples of beautifully carved holes in yucca stalks, apparently created by some non-human agent. We're trying to track down
how these holes were created, and if there is a possible link to how we learned to create primitive flutes with embouchure holes.

Pics and a bit of discussion is posted on a working page at:

Any thoughts, feedback, and ideas would be appreciated from this group .
