Radius Music is a never heard or seen before attempt at composing music using cartography and graphic scores. Devised by Dave Young the instrument is an autonomous rotating machine that uses synthesis technique comprising frequency modulation and additive synthesis to generate audio. The machine slowly rotates and scans the room to read the distance between it and people or objects and convert the same into a relative sonic frequency and visual score. Which means that each time you step in or walk out of the room, the machine would read the distance and accordingly sound too.
