G Classic Rock Loop
I – ♭VII – IV progression in G major
G Classic Rock Loop — I – ♭VII – IV
The G Classic Rock Loop (G – F – C) 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 (GMaj7 – F7 – CMaj7), it takes on a bluesier, more soulful character.
