Gm – E♭ – B♭ – F: the same four chords as I–V–vi–IV, started on the minor one. The Cranberries’ “Zombie” turns on this order. In B♭ major they are vi, IV, I 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.

Gm vi · root position

1 · ♭3 · 5 over G in the bass

E♭ IV · first inversion

3 · 5 · 1 over E♭ in the bass

B♭ I · second inversion

5 · 1 · 3 over B♭ in the bass

F V · root position

1 · 3 · 5 over F in the bass

Why it works

Starting on the minor chord makes the whole loop sound minor and searching, though not one chord has changed — the order of the same four chords is the whole difference.
