vi–IV–I–V · C major

Am – F – C – G

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

Am – F – C – G: the same four chords as I–V–vi–IV, started on the minor one. The Cranberries’ “Zombie” turns on this order. In C 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.

Am vi · root position

A1A1C♭3E5

1 · ♭3 · 5 over A in the bass

F IV · first inversion

F1A3C5F1

3 · 5 · 1 over F in the bass

C I · second inversion

C1G5C1E3

5 · 1 · 3 over C in the bass

G V · root position

G1G1B3D5

1 · 3 · 5 over G 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.

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.
