Randolph Denard Ornette Coleman (March 9, 1930 – June 11, 2015) was an American jazz saxophonist, trumpeter, violinist, and composer. He is best known as a principal founder of the free jazz genre, a term derived from his 1960 album Free Jazz: A Collective Improvisation. His pioneering works often abandoned the harmony-based composition, tonality, chord changes, and fixed rhythm found in earlier jazz idioms. Instead, Coleman emphasized an experimental approach to improvisation rooted in ensemble playing and blues phrasing. Thom Jurek of AllMusic called him "one of the most beloved and polarizing figures in jazz history", noting that while "now celebrated as a fearless innovator and a genius, he was initially regarded by peers and critics as rebellious, disruptive, and even a fraud."
Born and raised in Fort Worth, Texas, Coleman taught himself to play the saxophone when he was a teenager. He began his musical career playing in local R&B and bebop groups and eventually formed his own jazz group in Los Angeles, featuring members such as Ed Blackwell, Don Cherry, Charlie Haden, and Billy Higgins.
