Free Online Chord Transposer

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.

Each row is a key and each column is a chord in that key. Find your chords in the row of the key you play in, then read the same columns in the row of the key you want. Tap a key to transpose the chords above to it.

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

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.

1. Paste the chords

   Paste your chords into the box. A line like C G Am F works, and so does a whole song with chords above the lyrics or ChordPro chords in square brackets.

2. Check the key

   Check the original key. The tool detects it from the chords, and you can set it yourself in the From key menu.

3. Choose the move

   Pick the new key in the To key menu, or use the arrows and quick shift buttons to move by semitones.

4. Listen and copy

   Play the result to hear it, look at the shapes on the piano and fretboard, then copy it, export it as a .txt file or print it.

The Notes mode of the transposer moves a melody written as note names, either as letters (C, D, E) or as solfège (Do, Re, Mi). Type the melody, pick the shift and every note moves by the same number of semitones, the way a chord does. Chords are read and written in both systems too: Am is Lam and G7 is Sol7.

With accidentals, C♯ is Do♯ and B♭ is Si♭. In the result panel you can switch the names between C D E and Do Re Mi.

Three shortcuts under Common moves cover the requests that come up most often:

• Voice / E♭ moves the chords down three semitones. That's what an alto sax player reads from a concert chart, and a handy first try when a song sits too high.

• Ukulele moves the chords five semitones.

• B♭ moves the chords up two semitones, which is what a trumpet, clarinet or tenor sax player reads from a concert chart.

A♯ and B♭ are the same key on the piano, but a chart in F uses B♭ and a chart in B uses A♯. With Keep flats/sharps on (the default), chord names are spelled to fit the new key. Turn it off and the tool uses sharps when you move up and flats when you move down. Picking a target key in the To key menu gives the cleanest spelling.
