The glass harmonica is an instrument invented by Benjamin Franklin in the XVIII century who using the same principle invented this haunting instrument that consists of a set of glass vases conveniently arranged like a keyboard. Initially Franklin named it the 'glassychord', but soon settled on "armonica" due to the armonious angelic sound of the instrument which became an instant hit. Mozart and Bethoven both composed pieces for this odd instrument that was inded played by some historical characters like George Washington and Marie Antoinette.
