Due out early next year, Easy Piano lets you play piano with a 13-note, full-octave external keyboard that plugs into the Gameboy Advance slot of your DS. DSi owners need not apply.
The peripheral comes with software that can teach you how to play the piano or play music by following along on-screen prompts.
The game includes two difficulty modes and can also record up to four 3-minute songs.
I'm not sure if I'm quite ready to start adding plastic peripherals for my DS to my growing pile of plastic console controllers. What about you?
