Wagner was a remarkable innovator in both the harmony and structure of his work, stressing his own concept of the Gesamtkunstwerk, the ‘total work of art’, in which all the arts were brought together into a single unity. As a man he was prepared to sacrifice his family and friends in the cause of his own music and his overt anti-semitism has attracted unwelcome attention to ideas that are remote from his real work as a musician. In the later part of his career Wagner enjoyed the support of King Ludwig II of Bavaria and was finally able to establish his own theatre and festival at the Bavarian town of Bayreuth.
He developed the use of the leitmotif (in German Leitmotiv – ‘leading motif’) as a principle of musical unity, his dramatic musical structure depending on the interweaving of melodies or fragments of melody associated with characters, incidents or ideas in the drama. His prelude to the love tragedy Tristan und Isolde led to a new world of harmony.
