Motion-controlled musical tone control apparatus |
(57) An apparatus for the generation of musical sounds based on monitoring motions of
the body, especially the natural motion of swinging the arms and legs. The monitoring
of body motion depends on the use of an acceleration sensor in a hand-held element,
or on the use of an acceleration sensor contained in a detachable housing which is
held by a "Velcro" (Trademark) type means to a part of the body. The signal from the
acceleration sensor is transmitted via a cable or a wireless means to a musical tone
signal generating circuit which is contained, along with batteries, in a belt-shaped
casing which may be worn by the user. The musical tone generating circuit receives
signals from the acceleration sensor, and, using the musical tone colour information
stored in its memory, produces the appropriate output signal. Therefore, musical tones
can be generated simply by moving a monitored part of the body, without the actions
usually required to play an electronic musical instrument.
