A# Classic Rock Loop
I – ♭VII – IV progression in A# major
A# Classic Rock Loop — I – ♭VII – IV
The A# Classic Rock Loop (A# – G# – D#) 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 (A#Maj7 – G#7 – D#Maj7), it takes on a bluesier, more soulful character.
