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

B – G♯m – E – F♯

IB · B D♯ F♯
viG♯m · G♯ B D♯
IVE · E G♯ B
VF♯ · F♯ A♯ C♯

B – G♯m – E – F♯: the doo-wop changes, under “Stand by Me” and a whole decade of ballads. In B 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.
