In jazz harmony, the Coltrane changes (Coltrane Matrix or cycle, also known as chromatic third relations and multi-tonic changes) are a harmonic progression variation using substitute chords over common jazz chord progressions.
 These substitution patterns were first demonstrated by jazz musician John Coltrane on the albums "Bags & Trane" (on the track "Three Little Words") and "Cannonball Adderley Quintet in Chicago" (on "Limehouse Blues").
 Coltrane continued his explorations on the 1960 album "Giant Steps", and expanded upon the substitution cycle in his compositions "Giant Steps" and "Countdown", the latter of which is a reharmonized version of Eddie Vinson's "Tune Up".
 The Coltrane changes are a standard advanced harmonic substitution used in jazz improvisation.
