Creation of new connections inside sound-generating electronic devices to provide sounds unintended by their original designers. A wide range of effects can be achieved, and extra tactile controls such as potentiometers, switches, photocells, and body contacts can be added to control the new effects, the most frequent modification being for pitch control. Often various ‘bends’ are found accidentally by arbitrarily connecting two different points on the circuit board. Circuit bending has attracted considerable attention among persons interested in experimental electronic music and synthesizers, and it can be achieved with limited electronics knowledge and construction skills. Because circuit bending calls for unauthorised, sometimes radical changes to the circuitry’s original pathways, it risks damaging or destroying the device being modified. Toys are often exploited for circuit bending because of their ubiquity and low cost and the small risk of electrical shock from their low voltage. Battery-operated toys such as the Texas Instruments Speak n’ Spell and the Casio SK-1 have latent sonic potential and are prime targets for tinkerers seeking such sounds inexpensively or at no cost and because they tend to ‘glitch’ easily, spewing out fragmented bits of digital speech and strange sounds. Examples of circuit-bent creations include electronic keyboards, sound modules, drum machines, effects pedals, and karaoke machines. Video bending uses these same methods to modify video-game consoles to make abstract visual patterns in addition to novel sounds....
