Harmonic Analysis

This progression moves through A♭ (Tonic) → Fm (Submediant) → D♭ (Subdominant) → E♭ (Dominant).

The I–vi–IV–V progression defined the sound of 1950s doo-wop and early rock and roll. Its gentle descent from the tonic through the relative minor creates a warm, nostalgic feeling that has kept it popular well beyond its era. It remains a staple for ballads and sentimental songs.
