Terry Riley is an American composer born in 1935 who pioneered minimalist music through the use of repetitive structures, tape loops, and additive processes. His landmark 1964 work 'In C' established a foundational language for minimalism, employing simultaneous instrumental lines that gradually shift in phase, creating hypnotic harmonic densities. Riley's practice extends to electronic music, improvisation, and the integration of Indian classical music traditions into Western compositional frameworks. His work has profoundly influenced generations of composers working in minimalism, ambient music, and process-based composition.
