Chord transposer

How to use it

1. Paste your song into the left box. Chords can sit on their own line above the lyrics, or inline in brackets like [Am].
2. Check the "From key". The tool guesses it from the first chord. Fix it if the song starts somewhere else.
3. Pick the new key, or press + and − to move by semitones.
4. Copy the result. Choose sharps or flats if your players prefer one spelling.

Slash chords (G/B), extensions (Cmaj7, G7sus4, Am7b5) and minor chords are all transposed, and the spacing is adjusted so each chord stays over its word.

Choosing a key for a singer

The quickest test: sing the highest note of the chorus. If it strains, go down two semitones and try again. If the verses are too low to project, go up. Most songs move comfortably by a tone or a minor third without changing their character.

For a whole set or a medley, check that each new key also works with the songs around it. The medley key planner tells you how to get from one key to the next.

Questions

Does it work with chords inline in the lyrics?

Yes. Anything in square brackets that looks like a chord, such as [F#m7], is transposed, and the rest of the line is left alone.

Why does it write B♭ instead of A♯?

In auto mode the spelling follows the new key: flat keys (F, B♭, E♭, A♭, D♭) use flats, the others use sharps. You can force either one.

How does the capo suggestion work?

For the new key it finds a capo position that lets a guitarist play easy open shapes (C, G, D, A, E or Am, Em, Dm).

Is it free?

Yes, and nothing you paste leaves your browser.
