Harmonic Highlights:
- Employs a rapid descending major third modulation cycle (C -> Bb -> Ab) via successive ii-V-I progressions.
- Frequently tonicizes C major (V of F) through ii-V movements (Dm7-G7) and secondary dominants (A7 to Dm7).
- Utilizes chromatic ii-V progressions like C#m7-F#7, creating momentary departures and heightened harmonic color.
Improvisation Focus: Navigating rapid key changes and ii-V resolutions across various tonal centers.
Difficulty Rating: 4 (Advanced) - The quick, distant modulations and frequent reharmonizations demand a high level of harmonic fluency and adaptability.
