What is the significance and function of Richard Wagner's music in the history of world music?

Wagner's music is of special significance in the history of world music. His works have a great influence, and many composers follow his example. Under the influence of Wagner's music, Schoenberg, the founder of the modern twelve-tone system, created many modern music writing techniques, especially the opera Tristan and isolde.

Wagner played a leading role in the development of romantic music in the later period. The German Opera School headed by Wagner was founded. Its characteristics are: heavy, huge, symphonic and instrumental music, which is in sharp contrast with the Italian opera styles such as Verdi (emphasizing vocal music over instrumental music). After removing the vocal part, it is still a symphony. His works emphasize dramatic conflict and highlight the free and broken tone; Harmony emphasizes color and downplays functionality.
