- The progression utilizes a descending sequence of ii-V patterns (Ebm7-Ab7 to Dbm7-Gb7) that modulates down by a whole step to resolve on Bmaj7.
- It features a sophisticated chromatic dominant turnaround (B7-F7-Bb7), using the F7 as a secondary dominant to lead into the primary V chord.
- The structure employs modal interchange by shifting from a dark Eb minor foundation to a bright Eb major resolution at the end of the A section.
Improvisation Focus Navigating rapid ii-V sequences through descending whole-step modulations.
Difficulty Rating 4/5: The high-speed tempo combined with frequent modulations into distantly related keys requires advanced melodic fluency and harmonic precision.
