Harmonic Highlights
- Extended Modal Tonicization: The structure is dominated by a prolonged Eb minor 7th vamp (the relative minor of F# major), necessitating sophisticated melodic development over static harmony.
- Chromatic Step-wise Descent: The transition from Gb7 to Fm7 to Emaj7#11 creates a non-functional, sliding tension that bridges the modal sections.
- Lydian bII Color: The Emaj7#11 functions as a Neapolitan-style substitute, providing a bright, Lydian-inflected lift exactly one half-step above the Eb tonic center.
Improvisation Focus Eb Dorian scale fluency and rhythmic displacement over long modal stretches.
Difficulty Rating 4/5. The challenge lies in maintaining melodic inventiveness during the lengthy vamps while precisely navigating the high-speed chromatic turnarounds.
