6 months & up. Finally - a toy that makes beautiful music! Perfect for all ages, the award-winning, newly redesigned Mozart Magic Cube® inspires creativity and interactive play while teaching how sounds combine to create eight classical music masterpieces by the master composer.

Each selected instrument summary flashes to the tempo of the music. An orchestra summary even plays all the instruments at once. The Mozart Magic Cube® provides a fun musical foundation for your little one. And that's music to your ears - in more ways than one. Requires 3 AAA batteries (included).
