Richard Wagner

Wagner's 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 regarded as an important precursor towards modern music. As he matured, he softened his ideological stance against traditional operatic forms (ie. arias, ensembles and choruses), reintroducing them into his last few stage works, including ''Die Meistersinger von Nürnberg'' (''The Mastersingers of Nuremberg'') and ''Parsifal''.
To properly present his vision of the works, Wagner had his own opera house built to his specifications: the Bayreuth Festspielhaus, which featured many innovative design elements intended to immerse the audience in the drama. The premieres of ''The Ring'' and ''Parsifal'' took place there, and his most important stage works are performed at the annual Bayreuth Festival. The early success of the festival was secured by the efforts of his wife, Cosima Wagner, and has since been maintained by their descendants, attracting audiences from around the world.
Wagner's unorthodox operas, essays, and personal dealings engendered considerable controversy during his lifetime, and continue to do so. Declared a "genius" by some and a "disease" by others, his music is widely performed, but his views on religion, politics, and social life are debated—most notably on the extent to which his antisemitism finds expression in his stage and prose works. The effect of his ideas can be traced in many of the arts throughout the 20th century; his influence spread beyond composition into conducting, philosophy, literature, the visual arts and theatre.
