Morton Feldman was an American composer known for his unique approach to music, characterized by quiet dynamics and extended durations. Born in 1926, he became a prominent figure in the New York School of composers, which included notable artists like John Cage and Philip Glass. Feldman's work often explores the relationship between sound and silence, creating immersive listening experiences. His compositions frequently feature unconventional structures and a focus on texture rather than traditional melody or harmony. Feldman's music, such as Piano and String Quartet and Rothko Chapel, challenges listeners to engage with time and perception in new ways, making him a significant figure in 20th-century classical music.
