Harmonic Highlights:
- Utilizes Eø7 and Aø7 as chromatic leading-tone chords, building tension before resolving to Fm7 (ii) and Bbm7 (ii of IV) respectively.
- Features a clear modulation to the subdominant, with a strong Bbm7-Eb7-Abmaj7 (ii-V-I in Ab) progression.
- Employs a sophisticated descending bass line in the Abmaj7 - Abmaj7/G - Fm7 passage, demonstrating refined voice leading.
Improvisation Focus: Navigating ii-V-I progressions in both Eb and Ab major, emphasizing strong voice leading over chord changes.
Difficulty Rating: 4 (Advanced Intermediate) – Requires comfortable navigation of modulations, chromatic approach chords, and non-diatonic relationships beyond basic diatonic vocabulary.
