Richard Wagner, German composer, 1813-1883

Initially establishing his reputation as a composer of works in the romantic vein of Weber and Meyerbeer, Wagner revolutionised opera through his concept of the Gesamtkunstwerk ("total work of art"), by which he sought to synthesise the poetic, visual, musical and dramatic arts, with music subsidiary to drama, and which was announced in a series of essays between 1849 and 1852. Wagner realised these ideas most fully in the first half of the four-opera cycle Der Ring des Nibelungen (The Ring of the Nibelung). His advances in musical language, such as extreme chromaticism and quickly shifting tonal centres, greatly influenced the development of classical music.
