Chord transposer

Paste a song with chords and move it to any key with the right sharps and flats. Your text never leaves your browser.

Found a song but it is too high or too low for your voice? Paste it here with its chords and move it to any key in one tap. The transposer reads chords sitting on their own lines above the words, chords written inside the words in [brackets], and plain lines of chords, and leaves the lyrics untouched.

Chords are spelled the way the new key spells them, which is how musicians write them: moving a song in G up three semitones gives Bb, Eb, F and Gm, not A#, D#, F and Gm. Slash chords keep their bass note (D/F# becomes F/A), every chord type is understood, from sus4 to m7b5, and each chord stays over the same word, with the spacing adjusted when a chord name gets longer.

Tap the key you want and the number of semitones is worked out for you, or step up and down one semitone at a time until it suits your voice. If the new key is awkward on guitar, the transposer suggests a capo position with easier shapes.

Common questions

How do I change the key of a song?

Move every chord by the same number of semitones. Paste the song here and tap the key you want; the transposer moves every chord for you.

Why does it write Bb and not A#?

Keys use either sharps or flats. In F, Bb and Eb major the chords are written with flats; in D, A and E with sharps. Choose Sharps or Flats if you prefer one.

Is my pasted text saved?

No. It is read in your browser only, never sent to our server, never saved and never published. It disappears when you leave the page.

Can I use a capo instead?

Often, yes. The transposer suggests a capo position with easier shapes, and the capo calculator shows every option.
