The chords
Every chord links to its full reference page — notes, keyboard diagram, audio, fingering, and inversions.
Which key is it in?
A progression's key is the one whose scale contains all of its chords, and the Roman numerals below are each chord's job in that key. When several keys qualify, the ear usually decides by where the music comes to rest.
| Key | Roman numerals | Named pattern |
|---|---|---|
| F major | I – vi – IV – V | The Doo-Wop changes |
| D minor | ♭III – i – ♭VI – ♭VII | Not a named pattern |
Why The Doo-Wop changes works
The 1950s doo-wop loop: a gentle fall from home through the relative minor, then a lift back up through IV and V. Warm, nostalgic, and instantly familiar.
The full The Doo-Wop changes reference → covers variations, songs built on it, and the pattern in every key.
