ChordScore

Are your chords really landing together?

ChordScore listens to your piano over MIDI and measures, down to the millisecond, how evenly you strike the notes of a chord. Record a session, review your accuracy chord by chord, and see how hard you hit every single key.

Frequently asked questions

• Which pianos work? Anything that sends MIDI: over USB (using a Lightning or USB-C camera adapter) or over Bluetooth MIDI.

• Do I need a piano to try the app? No, there is an on-screen keyboard to practise with.
