Giuseppe Tartini (1692 - 1770) was an Italian Baroque composer and violinist. Today, Tartini's most famous work is the "Devil's Trill Sonata," a solo violin sonata that requires a number of technically demanding double stop trills and is difficult even by modern standards. (One 19th-century myth had it that Tartini had six digits on his left hand, making these trills easier for him to play.) According to a legend embroidered upon by Madame Blavatsky, Tartini was inspired to write the sonata by a dream in which the Devil appeared at the foot of his bed playing the violin.
