Richard Wagner
Wilhelm Richard Wagner (22nd May 1813–13th February 1883) was an influential German composer, conductor, music theorist, and essayist, primarily known for his operas (or "music dramas" as he later came to call them). His compositions, particularly those of his later period, are notable for their contrapuntal texture, rich harmonies and orchestration, and elaborate use of leitmotifs: themes associated with specific characters, locales, or plot elements. Wagner's chromatic musical language prefigured later developments in European classical music, including extreme chromaticism and atonality.
