Afro Blue (Ab major) - Jazz Analysis & Chords

Harmonic Highlights

• The progression functions primarily in F Minor (the relative minor of Ab major), utilizing a modal vamp structure that centers on the i-m7 chord.
• The movement from Db7#9 to C7#9 creates a bVI7–V7 cadence, employing dominant alterations to provide Phrygian-influenced tension before resolving to Fm7.
• The B-section introduces a diatonic stepwise descent (Fm7–Eb–Db), reinforcing the F Aeolian/Natural Minor tonality through a i–VII–VI progression.

Improvisation Focus F Minor Pentatonic and F Dorian scales are the most effective tools for navigating the modal vamps and the 6/8 polyrhythmic feel.

Difficulty Rating 2/5: The harmonic rhythm is slow and repetitive, making it accessible for intermediate players, though the specific 3/4 Afro-Cuban rhythmic pulse requires focused coordination.
