Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to a new type of musical instrument, and is applicable to special performing arts such as "instrument dance", "instrument gymnastics", "instrument acrobatics", "instrument fistfight", and performances. , related to musical instruments used for various contests and health management purposes.

[Prior art and its problems] Conventional butoh, in a broad sense, includes free gymnastics, acrobatic gymnastics, acrobatics,
Each of them, including the Military Kyoren, shows off their physical beauty on the podium and entertains the onlookers by performing the dance steps written by the choreographer.On the other hand, in traditional musical performances, the performers play ordinary instruments and the composer They play according to the musical score written by them, creating a musical effect among the audience. However, accompaniment for dance usually requires special skills. Therefore, these two performing arts cannot be performed on the same stage,
1 on the podium! ? It is impossible to bring out all of the talents of a performer.

[Objective and Summary 1 of the Invention The object of the present invention is to provide a device for use in entertainment and entertainment, and this device is equipped with a keyboard for a podium to play music by itself, and a stage. On this stage, a podium is used to display their dance performances. The podium combines instrumental music and dance art through performances based on ``dance choreography and musical scores'' or (!l) musical performances.This is up to #1 of special performing arts.

Another object of the present invention is to provide a device for performing entertainment performances, in which various artistic performances can be created depending on any combination of podiums through a kind of "light and color device". Can achieve light and color effects. The light and color change in sync with the musical instruments, completing a complex art of shape, sound, light and color, bringing out all the artistic talent on the podium.

The dance instrument according to the invention has a keyboard on which the podium can perform dances and which can be touched with feet, hands or other body parts or hand-held hammers to generate switch signals, and according to the invention The dance instrument also has a wall-mounted keyboard and a multifunctional electronic organ circuit. Certain switch signals are generated in response to a podium playing on a floor-standing keyboard, or in response to touching a floor or wall keyboard with a foot, hand, or other body part, or handheld hammer, which causes electronic circuits to It is transmitted to the keyboard circuit as a keyboard signal. The output signal of the electronic organ circuit is sent to an amplifier and a loudspeaker, and the corresponding scale is played.

The dance instrument according to the invention also includes a sound/optical signal separation circuit, an optical signal processing circuit, and an optical drive circuit. The sound/light signal separation circuit separates the switch signal into a scale signal and an optical signal, and the optical signal is processed by the optical signal processing circuit and then sent to the light drive circuit to separate the three primary colors of light, red and green. and a dyna of light that is fused with dance and tone by blinking a blue light source [Example] Examples of the present invention will be described below with reference to the accompanying drawings.
