Harmonic Highlights
- Initial sequence of minor 7th chords (Em7, Bm7, F#m7, Bbm7) establishes intervallic movement over functional harmony, creating an ambiguous opening.
- Features complex ii-V-I progressions to related (Cm7/F-F7-Bbmaj7) and distant keys (Gm7b5-C7b9 towards F minor), indicating rapid modulations.
- Incorporates non-diatonic major 7#11 chords (Dbmaj7, Gbmaj7#11, Ebmaj7#11) and altered dominants, characteristic of advanced post-bop harmonic vocabulary.
Improvisation Focus
- Precise arpeggio outlining and the application of appropriate altered scales for rapid harmonic shifts.
Difficulty Rating
- 5 (Advanced) - The tune’s frequent, non-diatonic modulations and sophisticated extensions require deep harmonic knowledge and technical mastery.
