Capitalizing on the success of such titles as Brain Age and Big Brain Academy, Rhythm n' Notes is a series of lessons and drills designed to teach you about music basics. From recognizing notes and chords to keeping time, each exercise gets progressively difficult as players become more proficient. As the title suggests, lessons are divided into two areas: rhythm, where you tap the screen to simulate percussion instruments, and notes, where you identify the correct notes or chords after listening to them played on a piano. Guiding players throughout each exercise is a whimsical creature named Tsumami.
