I–V–vi–IV (the “four chords”) · B major

B – F♯ – G♯m – E

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

B – F♯ – G♯m – E: the four chords under a great many pop songs — the verse of “Let It Be” is this progression in C. In B major they are I, V, vi and IV.

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

Two major chords, a minor, a major: the minor chord in third place is the shadow that makes the return to IV and I feel bright. Played with the smooth voicings above, the right hand moves by a step or two between every chord.
