- The progression prominently features the foundational ii-V-I (Cm7-F7-Bb6) in the tonic key of Bb major.
- A recurring V7/ii chord (G7) often follows the tonic Bb6, creating tension that resolves effectively to the Cm7 (ii) chord.
- The sequence Dm7-G7 functions as a ii-V progression leading to C minor (V/ii), reinforcing the movement back to the Cm7 (ii) chord.
Improvisation Focus: Focus on the Bb Major scale and its diatonic modes, specifically Dorian for Cm7 and Mixolydian for F7 and G7.
Difficulty Rating: 2 (Intermediate-Beginner). The clear ii-V-I framework and common secondary dominant movements make it manageable, but the frequent V/ii requires attention.
