Harmonic Analysis

This progression moves through D (Tonic) → C (Subtonic) → B♭ (Submediant) → A♭ (Dominant).

A dramatic chromatic descent through borrowed flat-side chords that creates a dark, unstable harmonic landscape. This progression is a favorite in modern jazz and fusion for creating tension over a descending bass line.
