Best capo positions for the (transposed) chords above — play these shapes and they will sound in the right key:
How to use the transposer
- Paste or type chords into the box. Chord names like Am7, F#m, Bb, Dsus4 and slash chords like D/F# are recognised.
- Move the slider to transpose up or down by semitones (1 semitone = 1 fret).
- Tick "use flats" for keys like F, Bb and Eb, which are written with flats.
- Check the capo finder for the easiest way to play the result.
Why change key?
- To suit your voice: if a song is too high to sing, transpose down a few semitones.
- To avoid barre chords: a capo lets you play in any key with open shapes.
- To play with others: match a singer, pianist or recording.

Frequently asked questions
How do I transpose chords down?
Move every chord down the same number of semitones. For example, down 2 semitones: G becomes F, C becomes Bb, D becomes C. The tool does this automatically.
Does a capo change the key?
Yes. Each fret raises the pitch by one semitone. With a capo on fret 2, a G shape sounds as A.
