How the Capo Transposition Calculator works
Each capo fret raises every open string by one semitone. To sound in a target key, play the shape that sits that many semitones lower. For example, a capo on fret 2 with G shapes sounds in A. Sharps are used for black-key names, so read C# as D♭ if you prefer flats. Example: with Key you want to sound D, and Capo fret 2, the result is Chord shape to play (key) = C; Semitones raised by the capo = 2; Sounding key if the capo moves up one fret = D#.
