What made John Coltrane’s style so famous?

Jazz saxophonist and composer John Coltrane’s vigorous, intense style is famous for its innovation. His “sheets of sound” approach is a style of improvisation in which notes are played rapidly with many overtones and undertones, creating a cascading effect, similar to a piano player striking chords rapidly. His tone on the tenor sax was huge and dark, with clear definition and full body, even in the highest and lowest registers. Coltrane also adopted the technique of multiphonics, which allowed him to produce multiple tones simultaneously.
