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

E – C♯m – A – B

IE · E G♯ B
viC♯m · C♯ E G♯
IVA · A C♯ E
VB · B D♯ F♯

E – C♯m – 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.

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.
