Wagner's compositions, particularly those of his later period, are notable for contrapuntal texture, rich chromaticism, harmonies and orchestration, and elaborate use of leitmotifs: musical themes associated with particular characters, locales or plot elements. Wagner pioneered advances in musical language, such as extreme chromaticism and quickly shifting tonal centres, which greatly influenced the development of European classical music.

He transformed musical thought through his idea of Gesamtkunstwerk ("total artwork"), the synthesis of all the poetic, visual, musical and dramatic arts, epitomized by his monumental four-opera cycle Der Ring des Nibelungen (1876). To try to stage these works as he imagined them, Wagner built his own opera house.

Early life

Geyer's love of the theatre was shared by his stepson, and Wagner took part in performances. In his autobiography Wagner recalled once playing the part of an angel. The boy Wagner was also hugely impressed by the Gothic elements of Weber's Der Freischütz. Late in 1820, Wagner was enrolled at Pastor Wetzel's school at Possendorf, near Dresden, where he received some piano instruction from his Latin teacher. He could not manage a proper scale but preferred playing theatre overtures by ear. Geyer died in 1821, when Richard was eight. Consequently, Wagner was sent to the Kreuz Grammar School in Dresden, paid for by Geyer's brother. The young Wagner entertained ambitions as a playwright, his first creative effort (listed as 'WWV 1') being a tragedy, Leubald begun at school in 1826, which was strongly influenced by Shakespeare and Goethe. Wagner determined to set it to music; he persuaded his family to allow him music lessons.

By 1827, the family had moved back to Leipzig. Wagner's first lessons in composition were taken in 1828-31 with Christian Gottlieb Müller. In January 1828 he first heard Beethoven's 7th Symphony and then, in March, Beethoven's 9th Symphony performed in the Gewandhaus. Beethoven became his inspiration, and Wagner wrote a piano transcription of the 9th Symphony, piano sonatas and orchestral overtures.

In 1829 he saw the dramatic soprano Wilhelmine Schröder-Devrient on stage, and she became his ideal of the fusion of drama and music in opera. In his autobiography, Wagner wrote, "If I look back on my life as a whole, I can find no event that produced so profound an impression upon me." Wagner claimed to have seen Schröder-Devrient in the title role of Fidelio; however, it seems more likely that he saw her performance as Romeo in Bellini's I Capuleti e i Montecchi. He enrolled at the University of Leipzig in 1831 where he became a member of the Studentenverbindung Corps Saxonia Leipzig. He also took composition lessons with the cantor of Saint Thomas church, Christian Theodor Weinlig. Weinlig was so impressed with Wagner's musical ability that he refused any payment for his lessons, and arranged for one of Wagner's piano works to be published. A year later, Wagner composed his Symphony in C major, a Beethovenesque work which gave him his first opportunity as a conductor in 1832. He then began to work on an opera, Die Hochzeit (The Wedding), which he never completed.
