Harmonic Highlights:
- Prominent use of the Bb7 chord as a bVII7, establishing a strong minor blues/Dorian harmonic character over the Fm7.
- The Bbm7-Eb7 (ivm7-bVII7) progression provides a classic minor-key color, functioning as a ii-V in Ab major, often resolving to Fm.
- Inclusion of the V7sus (C7sus) reinforces the dominant-tonic relationship in F minor, offering a stable resolution point.
- A distinctive descending chromatic movement from Cm to Bm before Bbm7 adds a unique non-diatonic flavor and unexpected harmonic tension.
Improvisation Focus: F Dorian scale.
Difficulty Rating: 3 (Intermediate) – While the core progression is simple, navigating the bVII7 and the unique chromatic non-diatonic movements requires thoughtful melodic choices.
