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

F – C – Dm – B♭

IF · F A C
VC · C E G

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

F I · root position

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.

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.
