Listen to French artist Thomas Bloch demonstrating a glass harmonica, or armonica, at the Paris Music Museum. From Wikipedia:

Benjamin Franklin invented a radically new arrangement of the glasses in 1761 after seeing water-filled wine glasses played by Edmund Delaval at Cambridge in England in 1758.[6] Franklin, who called his invention the "armonica" after the Italian word for harmony, worked with London glassblower Charles James to build one, and it had its world premiere in early 1762, played by Marianne Davies.
In Franklin's treadle operated version 37 bowls were mounted horizontally on an iron spindle. The whole spindle turned by means of a foot pedal. The sound was produced by touching the rims of the bowls with moistened fingers.

If you want to hear another interesting use of pitched wine glasses, check out Joseph Schwantner's "And the Mountains Rising Nowhere". Dr. Schwantner taught my composition instructor, Dr. Roger Briggs, also an awesome composer (you can find him on Facebook), at Eastman music conservatory.
These thigs are a delight to look at. And when they played it, my god what a wonderful sound.
