Free jazz is one name for the music of Ornette Coleman, Cecil Taylor, Albert Ayler, and their colleagues and disciples. Though Coleman and Taylor had recorded before the '60s, the free jazz term was not common until then. The free designation derives from Coleman's decision to offer performances that were not always organized according to preset melody, tempo, or progression of accompaniment chords. Freedom from these guidelines allows improvisers a greater degree of spontaneity than was available in previous jazz styles.
