His Violin Sonata in G-minor is the best known work by Italian violin virtuoso Giuseppe Tartini (1692-1770), notorious for its complex final movement which has come to be known as "The Devil's Trill". According to contemporary French scholar Jerome Lalande, Tartini claimed that the Devil played the piece for him in a dream, after which he struggled in vain to recall and record its full power.
