- The progression features a sequential descent of minor ii-V cells (Dm7b5–G13b9, Cm7b5–F13b9, Bbm7b5–Eb13b9) that move downward in whole steps, creating a sense of constant modulation.
- A chromatic turnaround sequence (Am7–D9–Dbmaj7–C13b9) utilizes the Dbmaj7 as a tritone substitute for the ii (Gm7) or a chromatic approach to the primary dominant.
- The consistent application of 13b9 tensions on dominant chords implies the Half-Whole Diminished scale, providing the characteristic “biting” tension found in Horace Silver’s hard-bop style.
Improvisation Focus Fluid navigation of sequential minor ii-V-i patterns.
Difficulty Rating 4/5; the rapid shifting of non-resolving tonal centers requires high-level harmonic agility and precise voice-leading at fast tempos.
