Play this pattern

Komuro Progression is a chord pattern you can play in any key. The degrees are vi–IV–V–I.

Leaves from the dark chord and arrives bright at the end. Fast dance pop uses it to push a chorus upward.

Patterns are common chord moves. They are not the chart of a recorded hit.

Patterns are named by theory. Play them in any key that fits your voice.

Each song page has a chord chart, fingerings, and the same song in every key.

How to sing it

The design is to start low on the dark first chord and sing loudest on arrival at the last. Every two bars it crosses from dark to bright once, so use it to lift a chorus.

Heard in

Get Wild · TM NETWORK. The Japanese name of this pattern comes from this song. The real chorus slips in one more chord, and in Korea the song is known as the City Hunter ending theme.
白日 (Hakujitsu) · King Gnu. Only the front of the chorus is these four chords. What follows mixes secondary dominants and passing diminished chords and is far more complex; the key is D♭ major.
千本桜 (Senbonzakura) · 黒うさP feat. 初音ミク. The song is in D minor, so the same four chords are heard as starting from the minor side. The tempo is very fast.

These songs use this pattern. This is not their chord chart: real recordings differ in key, rhythm and the chords they add.
