Wilhelm Richard Wagner 22 May 1813 - 13 February 1883) was a German composer, conductor, theatre director and essayist, primarily known for his operas (or "music dramas", as they were later called). Wagner's compositions, particularly those of his later period, are notable for their complex texture, rich harmonies and orchestration, and the elaborate use of leitmotifs: musical themes associated with individual characters, places, ideas or plot elements. Unlike most other opera composers, Wagner wrote both the music and libretto for every one of his stage works. Famous extracts from his operas include the "Ride of the Valkyries" and the Bridal Chorus from Lohengrin, popularly known as the wedding march "Here Comes the Bride". Initially establishing his reputation as a composer of works such as The Flying Dutchman and Tannhauser which were in the romantic traditions of Weber and Meyerbeer, Wagner transformed operatic thought through his concept of the Gesamtkunstwerk ("total work of art"). This would achieve the synthesis of all the poetic, visual, musical and dramatic arts, and was announced in a series of essays between 1849 and 1852. Wagner realized this concept most fully in the first half of the monumental four-opera cycle Der Ring des Nibelungen. However, his thoughts on the relative importance of music and drama were to change again and he reintroduced some traditional operatic forms into his last few stage works including Die Meistersinger von Nurnberg.
