There are more and more Flash Demos for the DS appearing on the net... in Japanese unfortunately :(
But it also means that some of them you can play on your wii :)

Players tap a series of floating notes in time with the music, filling up a "life" gauge with each successful hit. Missing a beat depletes the gauge, ending the level when the gauge is emptied.
