Abstract

The invention discloses a self-accompanying music stage and belongs to the field of cultural and recreational facilities. The self-accompanying music stage is characterized by comprising pedal keys and an electronic piano sounding system, wherein the pedal keys are arranged on a stage platform. Sound lines of an electronic piano are respectively connected to the lower side of a leaf spring on the bottom surfaces of the pedal keys. When a performer steps on a certain pedal key, the leaf spring on the bottom surfaces of the pedal keys is downward, the sound lines of the electronic piano are connected, and the electronic piano can make sound corresponding to notes. The self-accompanying music stage has the advantages that the performer can dance while singing and make accompanying music by himself, performance is full of variety, and the optimum matching of graceful dancing and melody can be realized. The self-accompanying music stage can bring revolutionary change and progress for human's cultural and recreational life.

Summary of the invention:

This project has been expanded existing intention thinking, and key is changed into circular foot key, is arranged on wide stage, and sing on dance limit, song and dance performer limit, and can oneself accompany, and can realize the best fit of graceful poise and melody.

Feature from accompaniment music stage is to consist of the foot key and the pianotron articulatory system that are arranged on stage table top; The acoustic circuit of pianotron is connected to the spring leaf below of each foot key bottom surface, and when going on the stage is set foot on certain foot key, the spring leaf of foot key bottom surface moves downward, and connects the acoustic circuit of pianotron, and pianotron sends corresponding note.

Described from accompaniment music stage, it is characterized in that, table top is double-decker, basal plane and end face, consists of, end face is closely connected with basal plane by stilt; On end face, have many holes of mating with foot key, foot key is arranged in described hole; Each foot key and and basal plane between have three equally distributed springs at least, spring supporting foot key make it with end face in one plane.

Described from accompaniment music stage, it is characterized in that, foot key is circular, can be also oval, square or rectangular.

Described from accompaniment music stage, it is characterized in that, three regions before, during and after table top is divided into by two row grey bands, three regions are respectively bass area, middle register and treble; Three regions all adopt staff form.

Described from accompaniment music stage, it is characterized in that, table top also can be divided into San Kuai region, left, center, right, is respectively bass area, middle register and treble.Every a line note is all to arrange from low to high, and each row is all an identical note.

Described from accompaniment music stage, it is characterized in that, table top also can be divided into center, outer ring and San Kuai region, edge, and fringe region is symmetrical bass area, and outer ring is middle register, and center is treble, the two rows note symmetric offset spread of middle register.

Described from accompaniment music stage, it is characterized in that, table top also can be divided into San Kuai region, left, center, right, wherein in district be divided into again before and after two parts.Two regions, left and right are that symmetrical rear portion, ，Zhong district, bass area is that front portion, middle register ，Zhong district is treble.

Described from accompaniment music stage, it is characterized in that, table top also can design like this: central point is a two high pitch note, and central point is around around high pitch note, and the outside of high pitch note is around middle pitch note, and the outside of middle pitch note is around bass note.

Beneficial effect from accompaniment music stage is, foot key is arranged on wide stage, and sing on dance limit, song and dance performer limit, and oneself accompaniment, and its expressive force is more rich and varied, can realize the best fit of graceful poise and melody.This project brings revolutionary variation and progress will to the mankind's entertainment life.
