HexJam is a high-quality, easy-to-play, Hayden-Wicki style hexagonal layout "Jammer-style" concertina for the iPhone/iPod Touch.
The scale patterns are very intuitive, and the built-in note guide makes it easy to learn to play!
Concertinas, sometimes called "squeezeboxes", sound like a small accordion or reed organ.
The 52-button keyboard can be configured to play with either the left or right hand. The keyboard has a 3 1/2 octave range.
There is a very good background article about Jammer keyboards on Wikipedia:
To play, simply touch the buttons.
Multiple buttons may be touched at the same time to play chords.
