PROGRESSION · I–vi–IV–V
The 50s Progression
The doo-wop loop. Unlike the axis progression it ends on V, so every pass genuinely wants to return to I. Also called the doo-wop changes, or the ice cream changes.
In C major
C – Am – F – G — nostalgic, sentimental, resolved, around 92 BPM.
Why it works
The bass descends a third from I to vi, steps down again to IV, then leaps up to V — a shape that keeps the harmony moving while the top voices barely change. Ending on the dominant means each cycle closes with real tension, so the loop propels rather than floats. That is the structural difference from the axis progression, which resolves early and coasts.
Where you'll hear it
Anything that wants to sound like 1958, and a surprising amount that does not. Slow it down and add sevenths and it stops sounding nostalgic and starts sounding like a ballad.
I–vi–IV–V in every key
The same progression transposed. The roman numerals never change — that is the whole point of writing progressions this way.
