The Glass Harp.
I am captivated by the haunting sounds of the glass harp, which are created by rubbing one’s fingers around the rims of glasses filled with the amount of water necessary to produce a particular pitch.
I was wondering what goes in to adding just the right amount of water to each of the glasses. Ya gotta love the internet, because my question was answered in the video below.
I gather that in 1761 Benjamin Franklin didn’t want to take the time to put water in all those glasses, so he invented the glass harmonica, which you can see being played here.
