Harmonic Highlights
- Employs rapid chromatic planing of Major 7th chords (Ebmaj7–Dmaj7, Gbmaj7–Fmaj7), bypassing traditional functional diatonicism in favor of parallel modal movement.
- Features disjointed minor 7th sequences (Dm7, Bm7, Abm7) that move by asymmetrical intervals, forcing the soloist to navigate unrelated tonal centers without standard ii-V-I pivots.
- Utilizes altered dominants (A7alt, Bb7#5) as deceptive pivots that create tension but often resolve into distant, non-diatonic major or minor targets.
Improvisation Focus The Lydian mode over Major 7th chords and the ability to transpose melodic cells rapidly across shifting tonal centers.
Difficulty Rating 5 (Advanced). The tune’s non-functional, fast-moving harmonic structure demands mastery of rapid-fire transposition and high-level modal fluency.
