D Classic Rock Loop
I – ♭VII – IV progression in D major
D Classic Rock Loop — I – ♭VII – IV
The D Classic Rock Loop (D – C – G) borrows the ♭VII chord from the parallel Mixolydian mode, giving it a rebellious, anthemic edge. This three-chord riff has powered rock music since the 1960s. With seventh chords (DMaj7 – C7 – GMaj7), it takes on a bluesier, more soulful character.
