- Chromatic Descending Tonicization: The progression features a clear pattern of major tonicizations (C, Bb, Ab) descending, each established through ii-V-I or similar movement.
- Non-Functional Dominants: Chords like B7 (to Bbmaj7) and A7 (to Abmaj7) serve as upper chromatic approaches, creating unexpected, non-diatonic voice leading.
- Dominant #11 Voicings: The frequent F9#11, Eb9#11, Db9#11 alterations on V9 chords add a characteristic Lydian dominant color and tension.
- Initial Tonic Deception: Despite the stated C minor key, the sample opens with Cmaj7/C6, immediately establishing a bright, major quality before complex modulations.
Improvisation Focus: Navigating chord-scale specific approaches, especially for the rapidly modulating ii-V progressions and altered dominants.
Difficulty Rating: 5 (Advanced). The rapid chromatic modulations, non-functional dominants, and consistent use of altered extensions demand a sophisticated harmonic understanding.
