- Employs “Bird Blues” architecture, featuring a minor ii-V (Gm7b5–C7b9) to the vi chord (Fm7) and a secondary ii-V (Ebm7–Ab7) to reach the IV chord (Dbmaj7).
- Utilizes sequential, descending ii-V patterns (Cm7–F7 to Bm7–E7 to Bbm7–Eb7) that move chromatically and through the cycle of fifths to return to the tonic.
- Features a “backdoor” ii-V (Dbm7–Gb7) acting as a sub-dominant minor substitution to bridge the IV chord back to the iii–VI–ii–V turnaround.
Improvisation Focus Voice-led navigation of descending ii-V sequences using chromatic guide tones.
Difficulty Rating 4 - The rapid harmonic rhythm and non-diatonic shifts through unrelated keys require high-level proficiency in connecting melodic cells across changing tonal centers.
