Harmonic Highlights:
- Features a dramatic Abm7-Db7-Gbmaj7 progression (bII-V-I in Gb), functioning as a chromatic mediant (bVI) to the home key of Eb.
- Frequent incorporation of minor ii-V-i progressions (e.g., Fm7b5-Bb7b13-Ebm7) adds a melancholic depth and parallel key shifts.
- Extended sequences of II-V movements (e.g., Am7-D7, Bm7-E7b9) rapidly shift temporary key centers, creating intricate harmonic motion.
Improvisation Focus: Chord-scale theory and arpeggio superimposition for fluidly navigating the numerous II-V progressions and modulations.
Difficulty Rating: 4 (Advanced Intermediate). The tune’s frequent chromaticism, distant modulations, and multi-key II-V sequences require advanced harmonic understanding and improvisational agility.
