- The initial Fm7, Db7, C7b9 progression introduces a bVI7 chord, functioning as a tritone substitute for V/V or an altered predominant leading to the V7b9.
- Standard iiø7-V7b9-i cadences (Gm7b5, C7b9, Fm7) firmly establish the F minor tonality.
- A complex descending chromatic sequence (Fm7, E7, Ebm7, D7) creates rapid, distant modulations, utilizing sequential dominant 7th chords or implied ii-Vs.
- Modulation to the relative major (Abmaj7) is achieved via conventional Bbm7, Eb7 ii-V-I progressions, offering harmonic contrast.
Improvisation Focus: Navigating rapid chromatic modulations and altered dominant chord tones.
Difficulty Rating: 4 (Advanced). The frequent, non-diatonic chromaticism and rapid modulations demand a sophisticated understanding of harmony and scales.
