I–vi–IV–V (50s Doo-Wop) (I–vi–IV–V)

The I–vi–IV–V (50s Doo-Wop) progression: I–vi–IV–V — in the example key of C, that is C – Am – F – G.

The classic doo-wop turnaround that soundtracked the 1950s: a major chord, its relative minor, then IV and V walking back home. Play it slow for a ballad or double-time it for a sock-hop shuffle. In the example key of C the chords are C – Am – F – G. Songs built on it include Stand By Me; Earth Angel; Blue Moon. Its mood palette leans nostalgic.
