Making music on Cognac Glasses (video)
The couple of the video in this article are very handy on Cristal Brandy Glasses, they call their table full of glasses a Glass Harp… Enjoy it!
Wikipedia about glass harps:
A glass harp (also called musical glasses, singing glasses, angelic organ, verrilion or ghost fiddle) is an instrument made of upright wine or Cognac glasses.
It is played by running moistened or chalked fingers around the rim of the glasses. Each glass is tuned to a different pitch, either by grinding each goblet to the specified pitch, in which case the tuning is permanent, or by filling the glass with water until the desired pitch is achieved.
