Be the first to rate this tooli–♭VII–♭VI–♭VII chord progression — how it works
The i–♭VII–♭VI–♭VII progression steps down from the minor tonic through the two major chords below it and back up, never touching a dominant, so it circles with a restless, natural-minor drive — the engine of many folk-rock and hard-rock verses.
It moves from the tonic (i) to the flat seventh (subtonic) (♭VII) to the flat sixth (♭VI) to the flat seventh (subtonic) (♭VII) and then repeats. Each chord lasts 4 beats, so one pass of the 4 chords is 4 bars of 4/4.
In A minor the chords are Am – G – F – G; in E minor they are Em – D – C – D. Press play above to hear the progression, then pick the key that fits your voice or your song and set the tempo you want to practise at.
