I–V–vi–IV Chord Progression | Vibepedia

The I–V–vi–IV chord progression, often dubbed the 'Axis progression' or 'Axis of Awesome' progression, is a foundational harmonic sequence in Western popular music. It comprises the tonic (I), dominant (V), submediant (vi), and subdominant (IV) chords of a diatonic scale. This cyclical pattern, with its inherent sense of resolution and melancholic uplift, has been a cornerstone of countless hit songs across genres from rock and pop to country and even some classical pieces. Its enduring appeal lies in its versatility and emotional resonance, allowing for endless melodic variations while maintaining a familiar, satisfying harmonic foundation.
