Benjamin Franklin
Musical endeavors

Franklin is known to have played the violin, the harp, and the guitar. He also composed music, notably a string quartet in early classical style. While he was in London, he developed a much-improved version of the glass harmonica, in which the glasses rotate on a shaft, with the player's fingers held steady, instead of the other way around. He worked with the London glassblower Charles James to create it, and instruments based on his mechanical version soon found their way to other parts of Europe. Joseph Haydn, a fan of Franklin's enlightened ideas, had a glass harmonica in his instrument collection. Mozart composed for Franklin's glass harmonica, as did Beethoven. Gaetano Donizetti used the instrument in the accompaniment to Amelia's aria "Par che mi dica ancora" in the tragic opera Il castello di Kenilworth (1821), as did Camille Saint-Saëns in his 1886 The Carnival of the Animals. Richard Strauss calls for the glass harmonica in his 1917 Die Frau ohne Schatten, and numerous other composers used Franklin's instrument as well.
