Harmonic Highlights
- The opening Em7 to Ebm7 creates a sudden chromatic half-step descent, introducing immediate modal ambiguity before settling towards the Eb minor key center.
- Bmaj7#11 followed by Bbm11 provides a strong modal contrast, temporarily evoking a bright Lydian sound before moving to a parallel minor.
- Frequent use of V7sus-V7#9 or V7b9b13 (e.g., D7sus-D7#9, Bb7b9b13) highlights altered dominant sounds and sophisticated, modern resolutions.
- The recurring Abm11-Bb7b9b13-Ebm7 firmly establishes a ii-V-i progression, consistently anchoring the piece in Eb minor amidst more complex movements.
Improvisation Focus Melodic minor scale and its derived modes (especially Altered Dominant and Lydian Dominant).
Difficulty Rating 5 (Advanced). The frequent altered dominants, chromatic shifts, and non-diatonic chords demand sophisticated harmonic understanding and rapid adaptation.
