Wagner

Wagner transformed opera into what he called Gesamtkunstwerk (total work of art), fusing music, drama, poetry, and visual spectacle into a seamless whole. His Ring cycle — four operas totalling 15 hours — is the most ambitious work in the history of Western music. His harmonic innovations, particularly the extended chromaticism of Tristan und Isolde, pushed tonal music to its breaking point. Wagner built his own opera house in Bayreuth specifically for his works, and the annual Bayreuth Festival continues to this day. He was also deeply controversial: his anti-Semitic writings and his later adoption by the Nazi regime have made his legacy a subject of ongoing moral debate, even as his musical influence remains undeniable.
