Doo-Wop / 50s (I–vi–IV–V)

The classic doo-wop progression from the 1950s. C–Am–F–G in C major gives that nostalgic, circular feel found in countless oldies, doo-wop songs, and early rock and roll. The smooth step from I to vi (relative minor) creates an emotional pull that made this progression irresistible to songwriters for decades.
