The Flying Dutchman, (Der fliegende Holländer) WWV 63, is a German-language opera, with libretto and music by Richard Wagner. Wagner claimed in his 1870 autobiography Mein Leben that he had been inspired to write the opera following a stormy sea crossing he made from Riga to London in July and August 1839. In his 1843 Autobiographic Sketch, Wagner acknowledged he had taken the story from Heinrich Heine's retelling of the legend in his 1833 satirical novel The Memoirs of Mister von Schnabelewopski (Aus den Memoiren des Herrn von Schnabelewopski). The central theme is redemption through love. Wagner conducted the premiere at the Semper Oper in Dresden in 1843. This work shows early attempts at operatic styles that would characterise his later music dramas. In Der fliegende Holländer Wagner uses a number of leitmotifs (literally, "leading motifs") associated with the characters and themes. The leitmotifs are all introduced in the overture, which begins with a well-known ocean or storm motif before moving into the Dutchman and Senta motifs. Wagner originally wrote the work to be performed without intermission – an example of his efforts to break with tradition – and, while today's opera houses sometimes still follow this directive, it is also performed in a three-act version.
