F Classic Rock Loop
I – ♭VII – IV progression in F major
F Classic Rock Loop — I – ♭VII – IV
The F Classic Rock Loop (F – Eb – Bb) 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 (FMaj7 – Eb7 – BbMaj7), it takes on a bluesier, more soulful character.
