Abstract
A musical apparatus which controls a variety of parameters of musical tones by detecting motion of an object in a space adjacent to the musical apparatus. More specifically, the musical apparatus may comprise a musical tone signal generator which generates a musical tone signal, at least one light source which radiates light beams into a space adjacent to the musical apparatus, at least one light detector which detects at least two light beams reflected from an object in the space and generates a detection value for each of said at least two light beams, a computing element which receives the detection values and generates a synthesized value; and a controller which controls parameters of musical tones based on the synthesized value. For example, the synthesized value may be the sum of the detection values, the difference between the detection values, the ratio between the detection values, or some other relationship between the detection values.
