John Coltrane, one of jazz’s most revered saxophonists, released “Giant Steps” in 1959. The chord progression that makes up the entirety of the song came to be called the “Coltrane changes”; it’s known across the musical world as one of the most challenging chord progressions to improvise over.
It’s tough for two reasons: The chord progressions are played fast, and they’re in three keys. “Giant Steps” is so challenging that Tommy Flanagan, the pianist on the original recording, could barely get through his solo before Coltrane took over.
