The Springboard is an electroacoustic coil spring instrument built in 1994 to explore the sonic potential of coil springs, wood, rubber bands, and practically any kind of found objects and readily available material. The vibrations of these objects and materials are amplified by a single, very affordable piezo disc contact microphone to create extraordinary sounds that belie their humble origin. ericleonardson.org/instruments/index.html.
