Mesa Musical Shadows
IDEA: Control music with your shadow in public space.
WHAT: The 'singing pavement' is installed in the north plaza at the Mesa Arts Center in Arizona. True to it’s name, shadows cast within the sensor- and speaker-laden plaza trigger melodic and percussive sounds, allowing individuals and groups to engage in spontaneous exploration, play, and composition across the geometrically tiled surface. Morning, midday, evening and night scores were composed to reflect varying atmospheres and — pragmatically — shadow lengths throughout the day. The sensors constantly recalibrate themselves in order to define new threshold values to determine what is a shadow and what is not. And since one can’t count on there being shadows 24 hours a day (and sometimes it is overcast) sounds are also triggered when the sensors are stepped on.
