Harmonic Highlights:
- The progression establishes a dominant F minor tonality (i-iiø7-V7b9) despite the stated F major key center, creating a minor-key feel.
- Features a secondary iiø7-V7b9 progression (Cm7b5-F7b9) resolving to the subdominant minor (Bbm7), characteristic of bebop harmony.
- Utilizes an Abm7-Db7 (ii-V to bII major) sequence, where the Db7 functions as a tritone substitution for G7, leading to the C7b9 (V7) of F minor.
Improvisation Focus: F melodic minor scale and its modes (especially altered and Lydian dominant).
Difficulty Rating: 4 (Advanced). The rapid harmonic rhythm, frequent ii-V progressions, and sophisticated substitutions demand advanced harmonic awareness.
