Richard Wagner was a German composer, conductor, and theater director, known for his groundbreaking contributions to opera. His works, such as The Ring Cycle and Tristan und Isolde, revolutionized the genre by integrating music, drama, and visual spectacle in unprecedented ways. Wagner's innovative use of harmony and orchestration, along with his concept of the Gesamtkunstwerk (total artwork), has left a lasting impact on the world of classical music. His operas often explore themes of mythology, love, and redemption, making him a pivotal figure in the Romantic movement.
