Harmonic Highlights:
- Establishes an initial C minor tonality (Cm, Cmb6, Cm6, Cm7), creating a poignant parallel minor contrast with the stated C major overall key center.
- Navigates through rapid modulations via interwoven ii-V-I progressions, shifting quickly to temporary keys like Bb major (Fmaj7, Bbmaj7), G minor (Am7b5, D7b9, Gm7), and D minor (Em7b5, A7#9, Dm6).
- Employs expressive minor-major seventh chords (implied Cm(maj7) and Bbm(maj7)) and striking chromaticism (Am7-Abm7-Gm7 sequence) for dramatic effect.
- Utilizes altered dominant chords (D7b9, C7#9, A7#9) to heighten tension and facilitate smooth transitions between diverse tonal centers.
Improvisation Focus: Chord-Scale Theory.
Difficulty Rating: 5 (Advanced). The frequent, complex modulations, use of altered dominants, and interplay between parallel major/minor demand sophisticated harmonic and improvisational understanding.
