Harmonic Highlights:
- The progression frequently tonicizes Fm7 (the relative minor) through the V7/vi chord (C7), establishing a strong F minor pull within the Ab major key.
- Features a prominent bVII7 chord (Db7) which functions as a non-diatonic dominant, infusing a distinct blues/gospel sound.
- The recurring sequence Db7-C7-Fm7 creates a unique cadential movement, blending a bluesy dominant with a strong secondary dominant resolution.
Improvisation Focus: F minor blues scale.
Difficulty Rating: 4 (Advanced Intermediate). The blend of diatonic, minor key, and non-functional blues harmony requires careful melodic navigation.
