- The progression utilizes chromatic side-slipping, opening with a non-diatonic Em11 that resolves down a half-step to the tonic Ebm11.
- It incorporates a modulation to the distant bVI key area (B Major) via a standard ii-V-I (C#m7-F#7-Bmaj7), typical of Silver’s sophisticated hard-bop structures.
- The structure relies on functional minor ii-V-i patterns (Fm7b5 to Bb7b9) and secondary dominants (Eb7b9 leading to Abm7) to define the subdominant minor regions.
- Chromatic dominant extensions and tritone relationships, such as the Fm7b5/B (functioning as a B7) moving toward Bb7, create dark, bluesy tension.
Improvisation Focus Eb Melodic Minor, which provides the necessary color for the tonic minor chords and the altered dominant tensions (Bb7alt).
Difficulty Rating 4/5 — The frequent shifts between distant tonal centers and the side-slipping chromaticism require advanced harmonic navigation and precise voice leading.
