The musical kinetic shape: A variable tension string instrument

Abstract - In this article we present a novel variable tension string instrument which relies on a kinetic shape to actively alter the tension of a fixed length taut string. We derived a mathematical model that relates the two-dimensional kinetic shape equation to the string’s physical and dynamic parameters. With this model we designed and constructed an automated instrument that is able to play frequencies within pre- dicted and recognizable frequencies. This prototype instrument is also able to play programmed melodies.
