Playing guitar? Use a capo for easier chords
A capo is a clamp on the neck that raises every string. Clamp it on the fret shown and play the chords on the card: it still sounds in A major.
Transpose chords chart
Transposing by hand: find your chord in your key's row, then read the same column in the new key's row. Am in C major is column vi; in G major, column vi is Em. The keys are in circle-of-fifths order, so each row has one more sharp (or one fewer flat) than the row above.
| Key | I | ii | iii | IV | V | vi | vii° | Signature |
|---|---|---|---|---|---|---|---|---|
| C | C | Dm | Em | F | G | Am | B° | no sharps or flats |
| G | G | Am | Bm | C | D | Em | F♯° | 1 sharp |
| D | D | Em | F♯m | G | A | Bm | C♯° | 2 sharps |
| A | A | Bm | C♯m | D | E | F♯m | G♯° | 3 sharps |
| E | E | F♯m | G♯m | A | B | C♯m | D♯° | 4 sharps |
| B | B | C♯m | D♯m | E | F♯ | G♯m | A♯° | 5 sharps |
| F♯ | F♯ | G♯m | A♯m | B | C♯ | D♯m | E♯° | 6 sharps |
| D♭ | D♭ | E♭m | Fm | G♭ | A♭ | B♭m | C° | 5 flats |
| A♭ | A♭ | B♭m | Cm | D♭ | E♭ | Fm | G° | 4 flats |

Capo chart
A capo raises every string by one semitone per fret, so you can play a song in a hard key with easy shapes. Tap a cell to hear what a shape becomes, slide the capo along the neck, and pick a chord to see how it is played on guitar or ukulele. To sound in B♭, play G shapes with the capo on fret 3.
| You play ↓ · Capo → | None | Fret 1 | Fret 2 | Fret 3 | Fret 4 | Fret 5 | Fret 6 | Fret 7 |

Capo on fret 2, play G → you hear A.

Frequently asked questions
How do I transpose chords?
Move every chord by the same distance. From C to D every chord goes up two semitones: C G Am F becomes D A Bm G. Paste your chords above, pick the new key, and copy the result: lyrics stay where they are.
How many semitones between two keys?
Count the piano keys, black ones included: C to D is 2, C to E is 4, C to F is 5, C to G is 7, C to A is 9. Going up 7 is the same key as going down 5, so pick whichever keeps the song in a range you can sing.
How do I transpose with a capo?
Keep playing easy open shapes and let the capo raise them. Each fret is one semitone: G shapes with a capo on fret 2 sound in A. The tool above lists the best shapes for the key you pick.
Can I transpose a minor-key song?
Yes. A minor song moves to another minor key: Am F C G a step up becomes Bm G D A. The tool keeps the song minor and lets you set the original key yourself if it guessed wrong.
Why does the song sound the same in a new key?
Because every chord keeps its job. In any key the first chord is home, the fifth wants to resolve, and so on. On the circle of fifths the key's frame of chords simply turns; the pattern inside it does not change.
