When the interface for music becomes collaborative “the interaction between the players becomes equally if not more important than the interaction between player and the interface. The technology recedes as the primary focus and becomes more a catalyst for social interaction.” (Robson, D, PLAY! : Sound Toys For The Non Musical, NIME). The idea of instruments encouraging play is not a new one, I have decided to alter the design of an iconic sonic toy (The stylophone) and create a collaborative version of it. My design has two separate interfaces built into the sides of one enclosure which forces the users to face each other when playing, encouraging social interaction when the device is in use. The speakers will be in close proximity to each other on the top of the device, having the sound sources close together will encourage the users to work together to attempt to create a unified sound.
