Chord transposer and capo calculator

The transposer understands the two common chord sheet formats and keeps your layout intact:

• Chords above the lyrics, each on its own line. Chords stay aligned over the right syllables, even when a chord name gets longer (C → C#m).
• Inline chords in brackets, as in ChordPro: [C]Ride with me, [G]ride.

Only real chord lines and bracketed chords are changed; lyric lines and section labels such as Intro: or Chorus are left alone. It recognizes a wide range of chord symbols: m, 7, maj7, m7, sus2, sus4, dim, aug, add9, 6, 9, 11, 13, m7b5, slash chords like D/F#, and more.

By half steps. Move every chord up or down by 1 to 11 half steps. One half step is one fret on the guitar or one key on the piano, including black keys.

Key to key. The tool estimates the song's key from its most frequent, first and last chords. Confirm or change it, choose the new key, and it works out the shift for you. Major keys move to major keys and minor keys to minor keys.

From G major	Shift	New chords for G D Em C
to A	+2	A E F#m D
to F	−2	F C Dm Bb
to E	−3	E B C#m A

With Sharps or flats? set to automatic, chords are spelled to fit the target key: B♭ in F major, A♯ in B major. You can also force all sharps or all flats. A list of every chord change (G → A, D → E…) appears under the result.

A capo raises every string by the same number of half steps, so you can keep playing easy open chord shapes while the song sounds higher. The calculator shows what you play and what sounds:

• Capo 2 + G shape = A. Play G, C and D shapes and the song sounds in A.
• Capo 3 + C shape = E♭. Play C, F and G shapes and the song sounds in E♭.

Choose the key the song should sound in and a capo fret; the tool lists every chord in the song as sounding chord → shape you play. It also suggests the capo positions where the most chords become easy open shapes (C, G, D, A, E, Am, Em, Dm), with the percentage of easy shapes, and includes a capo chart for the first seven frets.

• Fit your voice. If a song sits too high or low, shifting it two or three half steps often makes it comfortable.
• Easier chords. A song in B♭ or E♭ is full of barre chords on guitar; transposing to A or D, or using a capo, makes it much easier.
• Play with other instruments. Trumpet, clarinet and tenor sax players read in B♭, so their parts are written a whole step higher than concert pitch.

When you're done, copy the result or download it as a .txt file. The transposition happens in your browser; your text isn't uploaded. To look up a chord you don't know, use the chord finder.
