Ototo is an experimental synthesizer that enables any object to become a musical instrument through capacitive sensing. Capacitance (measured in farads, after the nineteenth-century English physicist Michael Faraday) is the potential for a body or object to store an electrical charge. The Ototo measures the latent capacitance of objects it is connected to, and when these objects are touched the energy in the player’s body is joined with that in the object to produce a note. Designer Yuri Suzuki is also responsible for the Colour Chaser, a miniature robotic vehicle that follows a circuit drawn with a black marker and translates color data drawn on top of it into sound. Suzuki has described how his own dyslexia spurred him to reinterpret the processes of composing, reading, and playing music.
