Benjamin Franklin Invents the Glass Armonica

1m 55s

Franklin developed a musical instrument that he called the armonica (after the Italian word for harmony). To play the armonica, a musician powered a foot pedal to rotate 36 concentric glass bowls and produced notes by putting wet fingers to the spinning glass. In Austria, the glass armonica provided the music for a royal wedding. Mozart and Beethoven would compose chamber pieces for it.
