Harmonic Analysis
This progression moves through E♭ (Tonic) → G (Mediant) → A♭ (Subdominant) → Abm (Subdominant).
The I–III–IV–iv progression features a chromatic ascent from I to IV via a secondary dominant III, then darkens with a borrowed minor iv. The III chord (V/vi) adds unexpected brightness while the iv creates a ♭ittersweet descent. This pattern appears in classic rock and singer-songwriter music.
