- The progression centers on the I-VI-ii-V turnaround (Ebmaj7-Cm7-Fm7-Bb7), a foundational cycle that reinforces the Eb major tonic.
- The inclusion of the secondary dominant V7/V (F7) instead of the diatonic ii (Fm7) introduces chromatic tension, pulling more aggressively toward the dominant Bb7.
- A stable subdominant (Abmaj7) provides a brief harmonic plateau, momentarily suspending the cyclic motion of the tonic-dominant turnarounds.
- Stepwise root movement and circle-of-fifths logic ensure smooth voice leading, typical of Vernon Dukeโs sophisticated yet accessible compositional style.
Improvisation Focus Eb Major Bebop scale and guide-tone navigation of the I-VI-ii-V cycle.
Difficulty Rating 2/5 - The predictable diatonic structure and standard ii-V-I patterns make it an ideal vehicle for practicing foundational jazz vocabulary.
