Capo

On guitar, a capo on fret N is the same as transposing down N semitones and reading the higher-key chords. Tap a fret to apply it.

Need a capo?

A capo does in one clamp what you just did with the transposer - and keeps the open-string shapes you already know.

How to transpose chords

Transposing means shifting every chord in a song up or down by the same number of semitones, keeping the harmonic relationships intact. Use it to adapt songs to your vocal range or to play with a capo.

  • Drop the key by 2–4 semitones if the song sits too high for your voice.
  • Use a capo to keep open shapes when transposing up.
  • If you know the original key, use the to-key dropdown for clean enharmonic spelling.

Frequently asked questions

What is chord transposition?
Transposition shifts every chord in a song by the same musical interval. The melody and harmony stay the same, only the pitch changes.
Why would I transpose a song?
To match a singer's range, to use easier shapes on guitar, or to play with another instrument like brass or strings.
How does a capo relate to transposing?
A capo on fret N raises every open chord by N semitones. Use the transposer to find the chord names you should read above the capo.
How accurate is the transposition?
We use the Tonal music theory engine, which preserves chord qualities (m7, sus4, add9, /bass) and respects enharmonic spelling whenever possible.
Can I transpose a whole song with lyrics?
Yes. Switch the editor to Song mode (or just paste your song - it switches automatically) and the transposer will change only the chord lines or [bracketed] ChordPro chords, keeping every chord aligned over the same word.
What are Nashville numbers and Roman numerals?
Both describe chords by their scale degree instead of a fixed name - C-F-G in C major becomes 1-4-5 (Nashville) or I-IV-V (Roman). Set the original key and use the notation toggle above the result to convert any progression or song sheet.
