It's surprisingly easy to learn how to play. Thanks to the symmetrical button layout, when you learn to play a C major chord, you can play all other major chords. Just move your hand around. Key names are displayed over the buttons to get you started.

Accordio implements the melody side of a 5-row chromatic button accordion and supports common layouts (B,C,G). You can play along to songs from your music library. Remember to turn off the silent switch.
