Transposition Tool
Paste a list of chords or a whole chord sheet and shift it up or down by any number of semitones — useful for matching a singer's range or switching capo position.
About this tool
Each chord's root note is shifted by the chosen number of semitones (positive = up, negative = down); any suffix — m, 7, maj7, sus4, dim, add9 and so on — is kept exactly as typed.
Paste a whole chord sheet and only the chords change: lyrics, bar lines and the spacing that lines chords up over the words stay where they are. Slash chords move both notes, so C/G up two semitones becomes D/A. The spelling follows the new key automatically, using flats for keys such as F, B♭ and E♭ and sharps for keys such as D, A and E, which is how the chords would be written in printed music. Going up a few semitones? Guitarists can often keep the original shapes and use a capo instead, and the tool tells you which fret. Only lines that are mostly chords are changed, so a lyric starting with “A” is left alone.
