Online chord transposer for key changes

The transposer handles a wide range of chord symbols: major (C, D, G), minor (Am, Em, Bm), dominant seventh (G7, A7), major seventh (Cmaj7), minor seventh (Am7), suspended (Csus2, Csus4), added ninth (Cadd9), diminished, augmented, and slash chords (G/B, C/E). The root note shifts by the chosen number of semitones while the chord quality and suffix stay the same.

Transposing is useful in many common situations: changing a song to a key that suits your vocal range, matching the key of another instrument in an ensemble, capo use on guitar (a capo on fret 2 means chords sound two semitones higher, so you transpose down 2 to read the original shapes), and learning a song that was recorded in a tuning different from standard.

Yes. When you input flat-root chords like Bb, Eb, or Ab, the transposer normalizes them internally and outputs the closest enharmonic equivalent. The output uses sharps by default (e.g. Bb becomes A#). If you prefer flats in the output, keep that in mind when reading the result — A# and Bb are the same pitch.

Yes. Paste the full lyrics with chords written above or inline (e.g. in the Nashville number style or standard lead-sheet format). The transposer recognizes chord symbols and shifts them while leaving all other text — words, punctuation, line breaks — completely unchanged.

One octave equals 12 semitones. Transposing by +12 or -12 brings you back to the same key but one octave higher or lower. Transposing by +7 moves up a perfect fifth (e.g. C to G), and transposing by +5 moves up a perfect fourth (e.g. C to F). These intervals are useful to know when changing keys on guitar.

A capo on fret 2 raises the pitch of all open strings by two semitones. If you play chords in open E-shape (E, A, B), with a capo on fret 2 those shapes sound as F#, B, and C# — two semitones higher. To find out what key a capo produces: take the original key and count up by the fret number. Capo 1 = +1 semitone; capo 2 = +2; capo 5 = +5. The chord transposer automates this — input your chords, set the offset to +2, and you see the sounding key.

G major and C major are widely considered the easiest keys for guitar because they use open chord shapes with no barres: G, C, D, Em, Am all have comfortable fingerings. E major and A major are also beginner-friendly. The 'hardest' common key on guitar is Bb major, because the two main chords (Bb and Eb) both require barre chords. If you want to play a song in Bb, consider transposing to A and using a capo on fret 1.

Set the semitone offset to -1. For example, if a song is in A (chords: A, D, E) and you transpose by -1, the output is Ab (G#), Db (C#), Eb (D#). If you want to keep easy open chord shapes, transpose -1 and add a capo on fret 1 instead — your hands play the original A-shape chords but the guitar sounds in Ab. This is the most practical approach for singers who need a slightly lower key.

Yes. Chord symbols are the same whether written for guitar or ukulele — Cmaj7 is Cmaj7 on both instruments. The transposer shifts root notes and preserves the chord quality, which is universal across fretted instruments. Paste your ukulele chord progression, choose the semitone offset, and the output is ready to use. The only difference is that the shape you play on the ukulele neck will differ from the guitar shape, but that is your instrument's concern, not the transposer's.

It changes the key while keeping the harmonic relationship between chords intact.

It supports common major, minor, sharp, flat and seventh chord names.
