"Handflute" is a kind of musical instrument played on the hands. The hands
are placed together as if praying. After making a space inside the gripped
hands, one blows into the gap between the two thumbs. It is similar to
making a tone by blowing over the top of an open bottle.
At first, only a simple piping sound can be produced with this technique.
However, by increasing or decreasing the size of the space inside the hands,
the tone can be controlled. Gradually, with a lot of practice, it becomes
possible to produce melodies. Mastering this technique takes a lot of skill
and practice, so very few people have this rare talent. http://www.youtube.com/watch?feature=player_detailpage&v=QiIj2gDzaNI
