Circular Laser Harp

－Laser Loop－

Abstract

In this paper, we propose “Laser Loop,” which is a circular musical instrument like a harp without physical strings. In this system, We employ lasers instead of physical strings. Lasers are radially irradiated from center exposure to light sensors which are arranged in a circle. A performer will play with their entire body with continuous circular motion without turning. This system also provides playing Shepard tone by natural motion.
