Harmonic Highlights:
- Extensive use of slash chords (triad over bass) generates rich, often dissonant maj7#11, min11, and altered dominant textures, e.g., Ab/G as Abmaj7#11 or Eb/D as Dmaj7#11.
- Frequent stepwise or half-step motion in the bass (G-F#, Eb-D, B-C#) creates characteristic suspended pedal point effects under non-diatonic upper structures.
- Non-functional harmony prevails with tritone/semitone relationships between upper structure roots (Ab to E, E to C), emphasizing coloristic rather than tension-release movements.
- The progression frequently features dominant 7ths with altered extensions (e.g., G/F# implies F#7#9#11b13) and a strong presence of Lydian colors (D/Ab implies Ab Lydian).
Improvisation Focus: Melodic Minor modes are essential for navigating the complex blend of #11, altered dominant, and minor 11th sonorities.
Difficulty Rating: 5 (Advanced) The highly chromatic, non-functional, and densely voiced harmony demands a sophisticated understanding of modern jazz theory and strong aural skills.
