He was one of the most influential composers of the 20th century, who experimented with diverse styles and techniques, including polyrhythm, polymeter, and changing meter. He used metronome markings to indicate his exact tempo preferences and to create contrast and tension in his music, such as in his ballets The Rite of Spring, Petrushka, and The Firebird.
He was a renowned conductor, composer, and educator, who blended classical, jazz, and popular music elements in his works, such as West Side Story, Candide, and Chichester Psalms. He used metronome markings to specify his desired tempo and mood, as well as to syncopate and accentuate his rhythms.
He is a leading figure of minimalism, a style of music that features repetitive patterns, gradual changes, and steady pulses. He used metronome markings to create a sense of continuity and structure in his music, as well as to facilitate the coordination of multiple instruments and voices, such as in his operas Einstein on the Beach, Satyagraha, and Akhnaten.
