Harmonic Highlights:
- Establishes a strong Eb major tonic through frequent I-V7 progressions (Eb6-Bb7).
- Utilizes a chromatic dominant (B7, bVII7) after Cm7 (vi), creating unexpected voice leading leading to Ebmaj7/Bb.
- Employs a classic #ivo7 (C#07) passing chord resolving to V7 (Bb7/D) before the tonic.
- Introduces a iiø7-V7b9 progression (Gm7b5-C7b9) indicating potential tonicization or a sophisticated turnaround.
Improvisation Focus: Eb Major scale and its diatonic modes.
Difficulty Rating: 3 (Intermediate) - While the primary key is clear, improvisers must effectively navigate several chromatic dominant and diminished chord movements.
