I–vi–IV–V (the ’50s progression) · E♭ major

viCm · C E♭ G

IVA♭ · A♭ C E♭

VB♭ · B♭ D F

E♭ – Cm – A♭ – B♭: the doo-wop changes, under “Stand by Me” and a whole decade of ballads. In E♭ major they are I, vi, IV and V.

Smooth voicings — root in the left hand

The right hand takes whichever inversion is nearest, so it moves by a step or two instead of jumping.

E♭ I · root position

1 · 3 · 5 over E♭ in the bass

Cm vi · first inversion

♭3 · 5 · 1 over C in the bass

A♭ IV · second inversion

5 · 1 · 3 over A♭ in the bass

B♭ V · first inversion

3 · 5 · 1 over B♭ in the bass

Why it works

I and vi share two notes, so does vi with IV, and V leads straight back to I: the bass walks down a third, down a third, up a step and home.
