Harmonic Highlights:
- Extensive use of ii-V progressions modulating through multiple key centers (e.g., Cm7-F7 to Bb, Fm7-Bb7 to Eb, Bbm7-Eb7 to Ab).
- The Em7b5-A7b9 opener, often leading to D minor, repeatedly functions as a V/Gm dominant, creating a recurring point of tension and resolution.
- Incorporation of non-functional dominant 7ths and altered chords (e.g., Ab7, Ebmaj7#11) introduces significant chromaticism and reharmonization possibilities.
Improvisation Focus: Chord tone outlining and navigating frequent modulations.
Difficulty Rating: 4 (Advanced Intermediate). Its rapid succession of ii-V progressions to various key centers and numerous altered dominant chords require constant harmonic awareness.
