Harmonic Highlights:
- Utilizes a B07 (B diminished 7) as a chromatic passing chord or substitution, creating tension and leading to non-diatonic resolutions.
- Features a distinct modulation to C major (bIII of Ab) via a clear Dm7-G7-Cmaj7 ii-V-I progression.
- Employs a modulation to Eb major (V of Ab) using a conventional Fm7-Bb7-Ebmaj7 ii-V-I, demonstrating clear sectional shifts.
- Integrates non-diatonic ii-V patterns, such as Bm7-Eb7, demanding advanced harmonic awareness and flexibility.
Improvisation Focus: Navigating rapid modulations and temporary tonicizations.
Difficulty Rating: 4 (Advanced Intermediate). The frequent and often non-diatonic modulations require strong chord-scale knowledge and quick harmonic adaptation.
