Almost every song you love is built on a chord progression — a repeating sequence of chords that gives music its emotional pull. The magic? A handful of progressions power thousands of hit songs. Learn these and you can play (and write) songs in any key.
This guide gives you a quick-reference chord progression chart, explains the simple number system pros use, and links each progression to real songs you can play right now.
What is a chord progression?
A chord progression is simply the order chords are played in a song. Musicians write them using the Nashville Number System — Roman numerals based on the scale, so the same progression works in any key:
- Uppercase = major chord (I, IV, V)
- Lowercase = minor chord (ii, iii, vi)
In the key of C, the numbers map like this:
| Number | I | ii | iii | IV | V | vi | vii° |
|---|---|---|---|---|---|---|---|
| Chord in C | C | Dm | Em | F | G | Am | B° |
| Chord in G | G | Am | Bm | C | D | Em | F#° |
