G10D 3/143 (20130101)
The present invention is a novel variable tension string instrument that relies on a kinetic shape to actively alter the tension of a fixed length taut string. A mathematical model was derived that relates the two-dimensional kinetic shape equation to the string's physical and dynamic parameters. With this model, an automated instrument was designed and constructed to play frequencies within predicted and recognizable frequencies along with programmed melodies.
