Chord Transposer helps transpose chords from one key to another. Add your song's original chord progression and the app will automatically transpose it in every key. This is useful if you're writing music or simply playing and need to change keys to support your vocal range.


On the main screen, create a new song to get started. Long-press a song to rename, delete, or share it. Click a song to begin adding your chords.

On the transposer screen, add all of your original chords and the table below it will automatically refresh with the same progression in each key. Click on a chord to modify/delete it, or insert another chord before/after it.
