Visitors can freely play and combine these sounds to discover and enjoy their own unique "good sounds." Furthermore, all sounds can be layered on the spot to "compose" music, with over 9.99 quadrillion possible combinations. Visitors can even take home their completed original sound creations.

The exhibition is planned and produced by CHOCOLATE Inc., the team behind numerous interactive experiences such as "Ano Shokuinshitsu" (That Staff Room).
