Sympathetic Resonance is an interactive musical instrument sculpture that utilizes the keys of a marimba (a mallet-percussion instrument of african origin) to create four and a half playable octaves. The sculpture consists of 56 "units," each containing a different note, as well as a yarn-wound mallet affixed to a rotary solenoid which allows the note to be triggered by a touch-sensitive aluminum keyboard played by the viewer. The sculpture's modular design allows it to completely change configuration from installation to installation. Each unit can be either mounted or placed on the floor or mounted to a wall, and can be connected to the keyboard with a wire of any length. joshuakirsch.com/symres.html
