Harmonic Highlights:
- Establishes a foundational I-vi-ii-V progression (
Eb6-Cm7-Fm7-Bb7), a core jazz harmonic staple. - Employs the classic ii-V-I cadence prominently (
Fm7-Bb7-Ebmaj7), reinforcing the Eb major key center. - Features a sophisticated
E07(E diminished 7th) as a passing #IVdim7, functioning asviiø7/iiand smoothly resolving toFm7.
Improvisation Focus: Eb Major scale and its diatonic modes (e.g., Dorian for Cm7/Fm7, Mixolydian for Bb7).
Difficulty Rating: 3 (Intermediate) – While mostly diatonic, the passing diminished chord requires understanding of common jazz substitutions and resolutions beyond basic major scale harmony.
