- Chromatic minor chord progression (Cm, Cmb6, Cm6) creating an ascending inner voice movement from Ab to A.
- Frequent use of secondary dominants (G7 to Cm, D7 to Gm) and a #I diminished (B07 to Cm) for temporary tonicization.
- A sophisticated ii-V to the subdominant (Fm7 - Bb7#5 leading to Eb) featuring an altered dominant, adding tension.
Improvisation Focus: Navigating local tonicizations by applying appropriate modes (e.g., Mixolydian, Dorian) and targeting chord extensions.
Difficulty Rating: 4 (Advanced Intermediate). The combination of chromatic voice leading, multiple secondary dominants, and an altered ii-V requires solid theoretical and improvisational skill beyond basic changes.
