Figured I'd go right to the top.
I've got confidence in your expertise.
Have you ever come across an instrument called a "Glass Harmonica". I saw this the other day on television and it blew me away. It seems to be designed around some sort of glass cylinder. there's forced air involved (I think), and tone and pitch are manipulated by finger/hand location. Gotta be one of the most bizarre things I've seen or heard.
Any knowledge on this...
Thanx for any info...
