Abstract
Movement of a musical instrument in space is employed to modulate its sound output. An electro-optical controller is used to detect the elevation of the instrument relative to the floor and, in turn, a control signal for modulating the sound output is generated.
Claims20
An arrangement for generating modulated sound, comprising:
- a) a support;
- b) means supported by the support, for transmitting radiation therefrom into an emission space;
- c) means for generating sound, including an inanimate sound-generating instrument movable relative to, and at a distance from, the support within the emission space, to direct radiation toward the support with a variable intensity proportional to the distance of the instrument relative to the support;
- d) means supported by the support, for sensing the radiation directed by the instrument, and for generating a control signal indicative of said radiation intensity;
- and
- e) control means operatively connected to the sensing means and the sound generating means, for modulating the sound with the control signal to generate a modulated sound.

A method of generating modulated sound, comprising the steps of:
- a) transmitting radiation from a support into an emission space;
- b) generating sound, including moving an inanimate sound-generating instrument relative to, and at a distance from, the support within the emission space, to direct radiation toward the support with a variable intensity proportional to the distance of the instrument relative to the support;
- c) sensing the radiation directed by the instrument, and generating a control signal indicative of said radiation intensity;
- and
- d) modulating the sound with the control signal to generate a modulated sound.
