Harmonic Analysis

This progression moves through Bbm (Tonic) → A♭ (Subtonic) → E♭ (Subdominant).

The i–♭VII–IV progression descends stepwise from the minor tonic through the subtonic to the subdominant, creating a classic Dorian-flavored sound. The major IV chord (borrowed from Dorian mode) gives it a brighter quality than typical minor progressions. It appears frequently in rock and folk music.

Song Examples

Oye Como Va, Santana
Smoke on the Water, Deep Purple
