Wilhelm Richard Wagner (/'v??gn?r/; German: '?iça?t 'va?gn? (About this sound listen); 22 May 1813 – 13 February 1883) was a German composer, theatre director, polemicist, and conductor who is chiefly known for his operas (or, as some of his later works were later known, music dramas). Unlike most opera composers, Wagner wrote both the libretto and the music for each of his stage works.He described this vision in a series of essays published 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 compositions, particularly those of his later period, are notable for their complex textures, rich harmonies and orchestration, and the elaborate use of leitmotifs—musical phrases associated with individual characters, places, ideas, or plot elements. His advances in musical language, such as extreme chromaticism and quickly shifting tonal centres, greatly influenced the development of classical music. His Tristan und Isolde is sometimes described as marking the start of modern music.Famously, he is known for Der Ring des Nibelungen (The Ring of the Nibelung), WWV 86, is a cycle of four German-language epic music dramas composed by Richard Wagner. The works are based loosely on characters from the Norse sagas and the Nibelungenlied.The four parts that constitute the Ring cycle are, in sequence: Das Rheingold (The Rhinegold) Die Walküre (The Valkyrie) Siegfried Götterdämmerung (Twilight of the Gods)Wagner had his own opera house built, the Bayreuth Festspielhaus, which embodied many novel design features. The Ring and Parsifal were premiered here and his most important stage works continue to be performed at the annual Bayreuth Festival, run by his descendants. His thoughts on the relative contributions of music and drama in opera were to change again, and he reintroduced some traditional forms into his last few stage works, including Die Meistersinger von Nürnberg (The Mastersingers of Nuremberg).
