Harmonic Highlights:
- Extensive use of highly altered dominant chords (e.g., Eb9#5, C7#5#9, G7#5#9, Bb7#5) generating significant tension.
- Employs sequential minor ii-V-i progressions (Gm7b5-C7#5#9-Fm7 then Dm7b5-G7#5#9-Cm7), often resolving to altered tonics or subdominants.
- Features a descending major 7th voicing movement (Abmaj7 to Dbmaj7) and resolutions to non-tonic major chords like Ebmaj7.
Improvisation Focus: Navigating altered dominant scales and chromaticism.
Difficulty Rating: 5 (Advanced) - Requires proficient command of altered dominant scales, complex harmonic substitutions, and non-diatonic resolutions.
