- The progression features a classic back-door resolution (IVmaj7 - bVII7 - I), moving from Abmaj7 through the Db7 subdominant minor substitute to the tonic Eb6.
- It utilizes an extended secondary dominant chain (iii - VI7 - II7 - V7), specifically Gm7 to C7 to F7 to Bb7, creating a strong circular motion back to the tonic.
- The use of the bVII7 (Db7) adds a sophisticated blues-inflected color, functioning as a common modal interchange from the parallel minor.
Improvisation Focus
Eb Major Pentatonic with the Eb Blues scale to capture the traditional “cocktail jazz” aesthetic.
