Chordado

About

Find your next chord — and learn why it works while you write. Built by a songwriter, not a theory expert: see every chord in any key, including the borrowed chords that make songs surprising, with guitar diagrams, piano keys, and real sampled sound. Pay once. No subscription. Pick a key, see every chord that belongs to it, and understand why. Chordado shows each chord with Roman-numeral analysis and puts borrowed (modal-interchange) chords right in context, so the theory is obvious instead of intimidating. Tap any chord to hear it played back with real sampled guitar and piano — then drag chords into a progression and play the whole thing. Save the progressions you love; they sync privately between your iPhone and Mac through your own iCloud.
