Harmonic Analysis
This progression moves through D♭ (Tonic) → D (Supertonic) → B (Subtonic) → D♭ (Tonic).
The I–♭II–♭VII–I progression borrows the exotic ♭II from Phrygian mode, creating a stark chromatic contrast against the major tonic. The ♭VII then provides a familiar stepping stone back to I. This pattern evokes Middle Eastern and Spanish flavors in a rock context.
