Harmonic Analysis
This progression moves through Am (Tonic) → G (Subtonic) → F (Submediant) → E♭ (Dominant).
The i–♭VII–♭VI–♭V progression descends chromatically through four semitone-related chords, creating a relentless downward pull. The tritone-related ♭V adds extreme dissonance and darkness. This progression is a hallmark of doom metal and dark progressive rock.
