“a light interference” is a participatory interactive sound installation for audience gestures, shadows, light sensors and speech synthesis. Shadow is usually silent but in this installation the audience’s shadow is made audible through the changes in the sound synthesis, triggered and personalized by the changes of their shadows.
The border between being conscious and unconscious, being controllable and uncontrollable, being the performer and the spectator, between immateriality and physicality, between music and visual arts is what we want to explore in this installation. The position of these borders depends on each person’s background and disposition. The shadow and the sound are the immaterial projections of the participants’ physicality.
The main result of this participatory work could be either the spectacular shadow, or the choreography of the individual audience, or the interesting changes in the course of sound enabled by the shadow movement, or any combination of these three. It depends on the inclination and background of each individual audience/performer. For example: Some might choose to focus mainly on the sound and the shadow intentionally, thus their physical body moves unintentionally. Some might be more aware of their physical body movement, thus their shadow and the sonic outcome is (partially) unintentional. Some are capable of paying attention to all the three elements simultaneously.
