Afro Blue — Chord Progression & Harmonic Analysis

One minor chord for most of the form, and a bridge that walks the flat seventh and flat sixth back to it. Almost no harmony, and a three-against-two rhythm that makes every bar feel like it could be counted two ways.

Why this example matters

Against a tonic of F minor the passage numbers as i – bVII – bVI. Inside those 7 chords there is a chord borrowed from the parallel mode. There is no dominant to lean on, so the phrase is carried by whichever note refuses to settle. Sustain each chord long enough to hear which one that is before moving on. Once you can hear it here, it is hard to miss in Blues for Alice, All Blues and So What.

How the rest of Afro Blue goes

A short modal form in F minor, sixteen bars in the usual charts: the tonic minor for most of the A section, and a bridge built from E♭ and D♭ major triads returning to F minor. The interest is rhythmic rather than harmonic — the melody and the accompaniment can be felt in three or in two at the same time, and good versions keep both alive.

Afro Blue on record

Mongo Santamaría, the Cuban percussionist, wrote and recorded it in 1959. John Coltrane’s quartet made it a jazz standard with the 1963 recording on Live at Birdland, where McCoy Tyner’s piano and Elvin Jones’s drums turn the polyrhythm into the subject of the performance.
