Freud would explore these ideas concerning sexuality further in his Three Contributions to the Theory of Sex, first published in 1905. As well as elaborating his theory of the 'Oedipus complex' (See note to page 201), he further explores the controversial idea that discrimination between sexual partners and practices is behaviour a person learns throughout their development, overlaying an "original bisexuality".

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.
