the isle of the dead
Glass harmonica should be an organ stop. [come on, how cool would that be?!?]
I haven't yet managed to make wine glasses sing (I did once, then couldn't do it again...) or those funky tibetan singing bowls. They're beyong me. But blowing in a bottle is dead easy to get a sound out of and changing the amount of water changes the pitch.... I've had fun with that before. biggrin
