G             G7      C        G
Amazing grace, how sweet the sound
G                   D
That saved a wretch like me

I once was lost, but now am found

Was blind, but now I see

About the Chord Transposer

A song is too high or too low for your voice? This free chord transposer moves every chord of a song up or down. Paste the song with its chords, press + or −, or simply pick the new key — every chord changes, and the lyrics stay where they were.

It reads both common ways to write chords: chords on their own line above the lyrics, and [C] chords inside the lyrics. A capo helper shows the shapes to play with a capo and finds the capo that gives the easiest chords.

Everything runs in your browser. Your song is not uploaded.

Features

  • Transpose by semitones (−11 to +11) or pick the new key from a list
  • Lyrics stay intact — only lines made of chords are changed
  • Chords above the lyrics keep their place over the right word
  • [C] inline chords (ChordPro style) work too
  • Sharps or flats — Auto follows the new key, or choose ♯ or ♭ yourself
  • Capo helper — the shapes to play with a capo, and the easiest capo for open chords
  • Any chord: m, 7, maj7, m7b5, sus2, sus4, add9, dim, aug, 6/9 and slash chords like D/F#
  • Copy the result or download it as a .txt file

How it reads your song

A line is a chord line only when every word on it is a chord. Bar lines |, repeat marks like x2, and labels like Chorus: are allowed on a chord line too. Every other line is a lyric line and is never changed — so the word *A* in "A man" or *Am* in "Am I wrong" stays a word.

Inside a lyric line, chords in square brackets like [G] are changed; a label like [Chorus] is left alone.

When a chord gets longer (G becomes G#), it keeps its column. The next chord moves right only if the two would touch.

Semitones and keys

There are 12 notes in Western music. One step from one note to the next is a semitone. Moving a song up 2 semitones turns every C into D:

Original+1+2+3−1−2
CC# / DbDD# / EbBA# / Bb
AmA#m / BbmBmCmG#m / AbmGm
FF# / GbGG# / AbED# / Eb
GG# / AbAA# / BbF# / GbF

So C – Am – F – G up 2 is D – Bm – G – A, and down 2 is Bb – Gm – Eb – F.

The key is shown as a best guess: the key whose own chords fit the song best, with extra weight for the first and the last chord.

Sharps or flats?

C# and Db are the same note, but music in a given key uses one name. Auto picks what the new key uses: the keys of F, B♭, E♭, A♭ and D♭ (and their minor keys, like Dm and Gm) are written with flats; the other keys with sharps. Choose ♯ Sharps or ♭ Flats to set it yourself. If your song uses the ♯ and ♭ signs, the result does too.

Capo chart

A capo raises every string by one semitone per fret. Play the shapes on the left with the capo on the fret at the top, and the song sounds in the key in the table:

ShapesCapo 1Capo 2Capo 3Capo 4Capo 5Capo 7
CC# / DbDEbEFG
GAbABbBCD
DEbEFF#GA
ABbBCC# / DbDE
EFF#GAbAB

Choose a capo in the tool and the result shows the shapes to play. The line Easiest tells you which capo (0 to 7) gives the most open chords — C, A, G, E, D, Am, Em and Dm.

Frequently asked questions

How do I transpose chords to a lower key?

Press − once for each semitone. Two semitones lower is a common change for singers. Or pick the new key in Or pick the new key.

Will it change my lyrics?

No. Only lines where every word is a chord, and chords in [brackets], are changed. If a lyric line is only one word that is also a chord name, like "A", it may be read as a chord.

What does the capo option do?

It shows the chord shapes to play with a capo on that fret, so the song still sounds in the new key. With capo 2, a song in A is played with G shapes.

Why is the key only a guess?

A song does not write its key down. The tool compares the chords with the chords of each key. Songs that change key, or use many borrowed chords, can fool it — then just use + and −.

Can it read chord sheets with tabs?

Tab lines (e|---3---) are left as they are. Only the chord names are moved.
