Paste any chord progression. Shift it to a new key in one tap, or find the capo position that turns barre-chord nightmares into easy open shapes. Runs instantly in your browser — nothing to install, no sign-up.
Some songs are written in keys full of barre chords. Put a capo on, play simpler open shapes, and it still sounds in the original key. Pick a capo fret and we'll show the shapes to play.
Where common open-chord shapes sound once you clamp a capo on:
| Capo | C shape sounds in | G shape sounds in | D shape sounds in | A shape sounds in | E shape sounds in |
|---|---|---|---|---|---|
| 1 | C# | G# | D# | A# | F |
| 2 | D | A | E | B | F# |
| 3 | D# | A# | F | C | G |
| 4 | E | B | F# | C# | G# |
| 5 | F | C | G | D | A |
| 7 | G | D | A | E | B |

Transposing means moving every chord by the same number of half steps (semitones) so the song lands in a new key — handy for matching your voice or another instrument. A capo does the same thing physically: clamp it on the Nth fret and your open shapes ring out N semitones higher, so you can play a song in a hard key using easy chords. This tool does the math both ways. The chord names are facts; trust your ear on the final voicing.
