Rock chord progressions

I, IV, V and back to IV: the three chords of rock and roll, turned into a riff that goes round and round.

Power chords, roots and fifths with no third, on I, ♭VII and IV: the riff shape of hard rock.

I–♭VII–IV, each chord a fourth below the last: the anthem sound of classic rock.

Rocking between the minor tonic and the major chords below it: dark and driving, from hard rock to metal.

A minor key with a major IV, the Dorian colour: moody, but with a lift.

Up from ♭VI through ♭VII to the tonic: the big stadium ending.

A major key with the ♭III chord borrowed from the blues scale: the swagger of blues rock.

The four chords of pop as power chords, fast and loud: the pop-punk progression.

Two chords a fourth apart, back and forth: the simplest rock riff of all.

Power chords on i, ♭III and IV: a riff shape behind a great deal of hard rock.

Power chords stepping up from ♭VI through ♭VII to the minor tonic: the climb of heavy metal.

Four chords stepping down to a major V, the Andalusian cadence played as a rock riff.

The chords of rock and roll in a different order, ending on IV: open and anthemic.

The minor tonic and the chord a half step above it, as power chords: the dark sound of metal.
