Turntablism is the art of manipulating recorded sound using direct drive turntables. Simple harmonic motion is a type of periodic motion used in physics where the restoring force is directly proportional to the displacement. Inspired by the concept of a harmongraph (a drawing machine using pendulums to create geometric Lissajous curves), this installation utilizes two turntables working in unison to produce an evolving image. Although an analog process the resulting drawings have a digital and mathematical quality to them and are also reminiscent of sound waves, in this case sine waves, viewed on an oscilloscope. The image output will vary depending on the speed, direction, time, relative starting position of the turntables platters and the length of their adjustable arms. The drawings can be further manipulated by manually adjusting the pitch controls of each turntable as they rotate. Turntablism for the Hard of Hearing is presented in the context of the Biennale internationale d'art numérique (BIAN), produced by ACREQ/Elektra.
