Each I Can Play Piano comes with 1 AC adaptor and 1 song-and-game cartridge. Additional song-and-game cartridges are sold for $14.99 each. The three-octave piano keyboard plugs into the television to create a plug-and-play piano system. Color-coded keys are the perfect size for small hands. The keyboard can also be used for   take-along play. The “learning magic” lies within the proprietary Piano Wizard technology in the song-and-game cartridges, turning standard sheet music into a colorful game with fun, moving images that tell kids what note to play and when to play it. I Can Play Piano is easy because kids set the tempo and learn at their own pace. Another great bonus is that kids of different ages (even Mom!) can collaborate and play together, and the simple game becomes a fun family experience.  Each time kids play, they’ll get a score and visual feedback on how well they played, just like playing a video game.  The better they play, the higher their score, with positive feedback and unconditional applause to encourage them every step of the way.
