Harmonic Highlights
- The opening establishes a clear I-vi-ii-V progression, firmly anchoring the tune in Eb major.
- A distinctive Abmaj7 to Abm7 (IV-iv) modal interchange provides a melancholic color, momentarily borrowing from the parallel minor.
- The unexpected Am7b5 chord, non-diatonic to Eb major, signals a potential secondary dominant preparation (e.g., iiø7 to D7-Gm7) or a pivot modulation.
Improvisation Focus: Navigating major key harmony with effective use of modal interchange.
Difficulty Rating: 3 (Intermediate) – While largely diatonic, the modal interchange (IV-iv) and non-diatonic Am7b5 require thoughtful melodic and harmonic navigation.
