Progression

The I–V–vi–IV chord progression or Axis progression (named after the Australian comedy rock band The Axis of Awesome, who popularized the chord progression's ubiquity), is a common chord progression popular across several music genres. It uses the I, V, vi, and IV chords of the diatonic scale. For example, in the key of C major, this progression would be C–G–Am–F. Rotations include: I–V–vi–IV: C–G–Am–F V–vi–IV–I: G–Am–F–C vi–IV–I–V: Am–F–C–G IV–I–V–vi: F–C–G–Am The '50s progression uses the same chords but in a different order (I–vi–IV–V), no matter the starting point.
