Harmonic Highlights:
- Prominent use of minor mode borrowed chords (Fm7, Abmaj7, Gm7b5, C7b9) creates a bittersweet, modal flavor within the F major context.
- A sophisticated dominant sequence (Dm7b5, G7b13, C7b9) employs a iiø7-V7 targeting C minor, immediately followed by the V7 of F, adding tension and harmonic richness.
- Clear secondary dominant resolutions and temporary modulations, exemplified by the ii-V-I-IV progression in Bb (Cm7-F7-Bb6-Eb7), which then pivots to a V7 of Ab.
Improvisation Focus: Navigating modal interchange.
Difficulty Rating: 4 (Advanced Intermediate). The frequent modal interchange, intricate dominant substitutions, and temporary modulations require a deep understanding of harmonic function.
