Red housing and white keys make this board easy to pick out on a shelf of muted toys, and at 1 pound it goes where a child goes. Thirty-seven standard-width keys sit above a panel of 8 tones, 8 rhythms and 22 demos, with one-key one-note mode and volume control for children still working out what each button does. The wired microphone included turns practice into a sing-along, usually the fastest route to a second session. Power comes from 3 AA batteries or the supplied USB cable plugged into an adapter rated 4.5 to 6 volts at 0.3 amps. The ABS body measures 16 by 6 by 1.5 inches, thin enough to store upright between a bookcase and a wall.
