John Coltrane was a musician and composer who played the tenor and soprano saxophones. He played with many great jazz musicians when he was young. He was always trying ways to find his own way of doing things, and he put together a small group of musicians (the John Coltrane Quartet) who all tried to find new ways of making music. They all changed the ways jazz musicians thought about how to play in a group with each other.
