Schoenberg claimed to be the successor of Richard Wagner in the tradition of German and Austrian music culture. For this reason, he had to deal with the latter’s antisemitic nationalism throughout his life. For Schoenberg, on the other hand, Wagner was at the centre of his artistic concerns, which always retained its vitality. The chapter shows that Wagner is at the centre of Schoenberg’s compositional experiments in his early work around 1900. In 1910, Schoenberg uses Wagner’s ideas as a starting point to justify his radical expressionism. Around 1920, he takes Wagner to task for introducing the twelve- tone technique; and around 1930 he fights with Wagner for his right to a German culture. In this way, Wagner’s enduring fascination is put at the service of continually changing needs.
