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

C – G – Am – F

IC · C E G
VG · G B D
viAm · A C E
IVF · F A C

C – G – Am – F: the four chords under a great many pop songs — the verse of “Let It Be” is this progression in C. In C 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.

C I · root position

C1C1E3G5

G V · first inversion

G1B3D5G1

3 · 5 · 1 over G in the bass

Am vi · first inversion

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.
