- The structure is anchored by repeated minor ii-V-i progressions (Em7b5–A7b9–Dm), emphasizing a traditional Afro-Cuban minor tonality with altered dominant resolutions.
- A secondary dominant (D7#9) provides a high-tension transition to Gm, functioning as a V/iv typical of minor blues variations.
- Chromatic side-slipping (Dm–Dbm–Cm7) serves as a sophisticated bridge to the F7 and Bb7 chords, introducing temporary tonal ambiguity through parallel motion.
Improvisation Focus D Harmonic Minor (specifically the A Phrygian Dominant mode over the A7b9 chords).
Difficulty Rating 3/5; the progression follows clear functional logic, but navigating the altered dominant extensions and chromatic transitions requires intermediate-level harmonic fluency.
