- Sequential Modulations: The structure utilizes a minor-third downward transposition, shifting from C minor/Bb major tonality to Eb minor/Db major tonality.
- Lydian Dominant Function: The Db7#11 acts as a pivot chord (bVII7), introducing a shimmering modal color that bridges disparate tonal centers.
- Chromatic Parallelism: The progression shifts from Db7 directly to C#m7, demonstrating a “side-slipping” harmonic motion common in modern post-bop standards.
Improvisation Focus Melodic Minor scale applications over shifting minor ii-V-I cells.
Difficulty Rating 4/5: The non-standard 40-bar length and rapid modulations through distant keys require advanced harmonic navigation and voice-leading skills.
