Description

A kind of piano key

Technical field

The utility model relates to piano, particularly relates to a kind of piano key.

Background technology

Piano (Italian: pianoforte) be a kind of musical instrument being derived from western classicality music.Traditional piano is made up of 88 keys (52 white keys, 36 black keys) and metallic cord soundboard, and black key is arranged on the first half of fingerboard, and for projecting, when playing, player needs the complexity change carrying out 12 kinds of modified tones.

And traditional piano performance method is complicated, cannot by playing all songs with a kind of playing method.

Utility model content

A kind of piano key, comprise 44 black keys and 44 white keys, black key and white key are alternately arranged according to single order semitone.

The center section of black key raises up, in " convex " font; The center section of Bai Jian, to lower recess, is " recessed " font.

One of them embodiment, the center section that black key raises up is consistent with the height at Bai Jian two ends; The center section of Bai Jianxiang lower recess is consistent with the height at black key two ends.

One of them embodiment, black key length is consistent with white key length.

One of them embodiment, the width of black key is consistent with the width of white key.

Above-mentioned piano key, there are 44 white keys and 44 black keys, the white key of black key is alternately arranged, it is the same method that such design makes to play black key with playing Bai Jiandou in performance, there is the function of " tune is logical ", achieve 12 and adjust same playing method, be equipped with straightaway number spectrum, reduce the difficulty of performance.

Embodiment

For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.First-selected embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, the object of these embodiments is provided to be make to disclosure of the present utility model more thoroughly comprehensively.

It should be noted that, unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in instructions of the present utility model herein just in order to describe specific embodiment, is not intended to be restriction the utility model.

A kind of piano key, comprises 44 black keys 1 and 44 white keys 2, and black key 1 and white key 2 are alternately arranged according to single order semitone.

Wherein, the center section of black key 1 raises up, in " convex " font; The center section of white key 2, to lower recess, is " recessed " font.

Preferably, the center section that raises up of black key 1 is consistent with the height at white key 2 two ends; White key 1 is consistent with the height at black key 2 two ends to the center section of lower recess.

Preferably, the length of black key 1 is consistent with the length of white key 2.

Preferably, the width of black key 1 is consistent with the width of white key 2.

Performance Region dividing of the present utility model:

There is provided one below preferred embodiment:

The floor plan of piano key:

Singly organize key:

Because black key 1 and white key 2 are in same plane, and black key 1 and white key 2 arrange according to single order semitone, and play so convenient realization " chromatic scale " is scraped fast, this is a kind of acoustics never occurred.

Exemplify three kinds below and scrape the mode of playing:

" chromatic scale " is scraped and is played (straight line):

" diatonic scale " is scraped and is played (near-sinusoidal):

" minor third scale " is jumped and is scraped (serrate broken line):

Be equipped with preferred " number spectrum ", " number spectrum " method for expressing is as follows:

1, the formation of number spectrum " roll call stopwatch "

2, the tone mark of number spectrum: become owner of by the actual musical alphabet of each sound group, from large word one group to small character four groups, any musical alphabet all can make tone mark.

3, the note method for expressing of number spectrum: by arabic numeral boldface type 1,2,3,4,5,6,7,8,9 and English alphabet boldface type X, Y, Z, the note jointly forming 12 musical notes is 1,2,3,4,5,6,7,8,9, X, Y, Z.This note permission various countries and local voice are sung, Chinese be mandarin " one, two, three, four, five, six, seven, eight, nine, think, dimension, person " pronunciation.This pronunciation series only does oral chanting, and mustn't be used for the work of software note spectrum.

4, number spectrum beat and speed method for expressing: specified by heading beat and speed, because the every lattice of Ben Biaoge are exactly a chronomere, sound Qu Yidan starts, and the time constantly advances, and just as track and field manual time-keeping, therefore says " roll call stopwatch ".

5, number spectrum special token:

Mark during contracting: , no matter how many sounds, lower stroke of this thick line person, is considered as a bat or front sound partly.

Mark during expansion: , everyly add every line person, often to increase when lattice expand one times, lattice number is only pressed in timing.

Fall apart mark: , single line adds numeral, laxity rhythm.

Left alone without help sound mark: save left alone without help, clap left alone without help, dot is left alone without help.

Repeat sign: joint repeats ; Clap and repeat ; Duan Chongfu ; Repeat from sentence ; Non-ending repeats .

Mark is follow-up: , mark follow-up left alone without help on , mark reduces , need the filling of every sound.

Liaison mark: , , .

Appoggiatura mark:

Concept audio amplifier, harmony need divide the person of playing, available, and in case, multitone is by bending down upper high principle mark with phonetic symbols.

In character narrate, all notes can add up and down indicate height.

Useless lattice mark , differ from lattice at end of line, lattice can be increased.

All the other are consistent with traditional mark.

The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
