vi–IV–I–V · E♭ major

Cm – A♭ – E♭ – B♭

viCm · C E♭ G
IVA♭ · A♭ C E♭
IE♭ · E♭ G B♭
VB♭ · B♭ D F

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

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.

Play it. See every name.

The free chord finder names whatever you play — on a MIDI keyboard, with the mouse or on your computer keys — with the same engine as Cadenza.

Or let the app follow you.

Cadenza names every chord you play, live, with the degree over each key — and writes what you played as sheet music. The core is free forever, on Mac and Windows.
