- Initial prolonged Am (iii chord in F) followed by a stark shift to Cm (bVII minor), creating early harmonic ambiguity and modal interchange.
- Features a series of rapid ii-V-I modulations descending by major thirds (Bb, Ab, Gb), demanding agile key center navigation.
- A classic ii-V-I (Gm7-C7-Fmaj7) firmly re-establishes the F major tonic after complex modulations.
- The E7#9 provides a strong blues-inflected, altered dominant, hinting at a potential V/iii or tritone substitution before further development.
Improvisation Focus: Navigating rapid, non-diatonic ii-V-I cycles across descending major third key centers.
Difficulty Rating: 4 (Advanced) The frequent, non-diatonic modulations and the use of altered dominants require a high level of harmonic sophistication and fluidity.
