Rhythm 'n Notes hands-on at IGN.
"With all the musical games out on the Nintendo DS, what are the musically impaired supposed to do? How can you enjoy Elite Beat Agents when you have no rhythm? Enter Agetec and the new Rhythm 'n Notes game, an educational music game designed to teach you about, like, chords and stuff. We got to try it out for a bit and found out just how much we suck at listening.
There are two elements to Rhythm 'n Notes. There's the (get this) Rhythm section and also the (wait for it) Notes section. Both sections have a variety of lessons to teach you, the tone deaf player, how to recognize notes and chords, and learn how to keep time."
