This play-along harmonica features guiding flashing lights: red means blow out, blue means suck in, helping kids learn the six included tunes. When they're more confident, they can switch to Tutti mode to speed up and hear accompanying instruments! The light panel is adjustable, and the harmonica can also be played without the light guide; a li-battery is included. Size: 18.5 x 8.5 x 18 cm. Ages 3+.
