Three flats. Horn players feel right at home. Guitarists either capo 1 and play D shapes or tune down a half step and play in E.
| Chord | Number | Roman |
|---|---|---|
| E♭ | 1 | I |
| Fm | 2m | ii |
| Gm | 3m | iii |
| A♭ | 4 | IV |
| B♭ | 5 | V |
| Cm | 6m | vi |
| Ddim | 7° | vii° |
The 1, 4 and 5 (E♭, A♭, B♭) are the backbone. Add the 6m (Cm) and you can play most of what's on the radio. The 7° (Ddim) mostly shows up as a passing chord, so don't lose sleep over it.
Those numbers are the Nashville number system. Learn the progression as numbers once and it works in every key.
Capo 1, play D shapes; capo 3, play C shapes; capo 6, play A shapes.
The capo chart has every key, and the transpose chart moves a song somewhere else entirely.
Songs that leave E♭ usually go to its 4 or 5: key of A♭ or key of B♭. Or see every key.
Chartless listens to whatever is playing and shows the key, the chords and the numbers live, so you can check a recording against this page while it plays. How to find the key by ear if you'd rather do it yourself.
