Keys have come to signify more than just their function as an object that locks and unlocks. Through representation and association we have constructed metaphors around keys. In superstition they can be the both the bearers of good luck and bad luck; keys have come to represent knowledge, mystery, initiation, curiosity, power, status, ownership and authority. However, the illusion of metaphor does not bring a semblance of truth to the object, we ignore the objects basic function as a key and come to view it on a metaphysical level. We perceive phenomena differently on the left and right side of the brain. The left being analytical, logical and objective, in contrast to the right; thoughtful, intuitive and subjective. In this installation the left speaker plays sounds of locks being closed, while the right speaker plays sounds of locks being opened which symbolises the left and right side of the brain respectively.
