Blue - Ebmaj7 ii-V-I - Ebmaj7 is the IV of the Bbmaj7 the original key.Red - Turnaround + diatonic substitution.To help you understand the role of the turnaround, here is a common rhythm changes sheet in the key of Bb with a chord analysis and a color code. The most commonly used key to play in is Bb major, which is the key we are focusing on in this lesson. We find this sequence on bars 1-2-9-10-25-26 and generally a variation (iiim7-VI7-iim7-V7) on bars 3-4-7-8-11-12-27-28 with a diatonic substitution. Its name stems from the George Gershwin tune "I got rhythm".

The basic rhythm changes is a 32-bar AABA form, but there are many variations. The iim7 chord is changed into a dominant chord (V7). This progression is a part of what we call "rhythm changes".

The most known turnaround variation is the Imaj7-VI7-ii7-V7 chord progression. Jazz chord progression # 5 - Turnaround variation - Imaj7 - VI7 - iim7 - V7 (Rhythm changes) What's the Rhythm Changes Turnaround? However, the V chord will undergo a few changes. There is no change for the minor (II) and the major (I) chords. This will create tension, an imbalance of the V7 chord which should resolve to the I chord to release this tension. It means that we will add altered notes not present in the original scale (the major scale). These altered notes are b9, #9 #11 ( b5) and b13 (#5). The next step in exploring the most important jazz chord progression is to consider the V7 as an altered chord (Valt or V7alt). However, only playing notes of the diatonic scale can be boring in the long run. It is a nice introduction to jazz comping.
