Designed for iPhone Duo. A little fold, a little folk.
Turn your Duo into a pocket concertina: gently open and close the fold to give the music its air. On other iPhones and iPads, drag the red touch bellows. Closed Duo also plays with touch on its outer screen.
START PLAYING FREE
Ode to Joy is included in both Demo and Learn modes. In Demo, we press the notes while your movement sets the pace. Tap Learn it to follow the glowing keys yourself.
