Today we are looking at Jazz improvisation master John Coltrane and his approach to chord changes.
Both “Countdown” and “Giant steps” have become classic “Trane changes”.
If you look at the diagram below you will see the reharmonisation of the basic 2 5 1 cadence resulting in the “Coltrane changes”.
We will now take the first 4 bars of John Coltrane’s Composition “Countdown” and play it in all 12 keys moving in 4ths. Below are two examples of what to play using 4 note groupings [Tetrachords}
Coltrane’s countdown first 4 bars idea starting with D minor 7th
John Coltranes’s Countdown up a 4th starting with G minor 7th

Play through all 12 keys for fluid jazz improvisation development in the John Coltrane style.
