Description

12 average series of sound formula keyboards

Technical field

The utility model belongs to a kind of keyboard of keyboard instrument.

Background technology

Before 14th century, the keyboard instrument of being invented by the European only has the c major scale, by continuous evolution, in filling 5 black keys 14th century.The Bach finishes the immortal twelve-tone equal temperament prelude of two covers and composes lattice in the creation of 18th century, and this keyboard instrument is generally acknowledged by people.Thus, with the sound of 12 average five equilibriums with satisfactory to both parties half, three full semitones, i.e. 7-5 system, the keyboard of arrangement formalizes substantially, has continued to use sexcentenary, has become the king of the musical instrument of human natural formation so far; No matter its organ of developing, accordion, mellotron have all followed corresponding pattern.But after 19th-century key button formula accordion comes out, initiated challenge to keyboard musical instrument, that is arranged flexibly, broad range, and fingering easy, the advantage of performance has all exceeded piano-accordion.Because of arranging rationally, make learner and player reduce a large amount of practice periodses, thus, the drawback of 7-5 system just is completely exposed.The technical elements rule incessant at mode, tone mark, fingering, the mark of changing voice etc. is various, and numerous philharmonic persons is hung back, and has seriously hindered popularizing of keyboard instrument.In modern today, this musical instrument that consumes a large amount of practice periodses for no reason ancient, the old tradition formula is needed badly and is reformed to adapt to the demand of popular learning music, make that learning music no longer mystifies, complicated, hereditaryization, pedantryization, allow new-type, the keyboard of simple and scientific replaces more.

The white key of 7-5 system keyboard is not only long but also wide, and black key is not only short but also narrow, but is controlling with ten fingers equally, and this process is quite complicated difficult, is easy to tiresome and can't bear, and especially its structure of the people of adversary's finger spare deficiency makes many songs can't bear performance.

7-5 system keyboard Designing on organ, accordion, mellotron is narrower slightly and volume ratio is more reasonable.But piano is because white key has 52, and black key has 36, and the huge musical instrument of this bodily form is for the European who grows up designs use, people's nature exclusion that this just plays the song requirement with numerous music talentes because of height, arm, finger do not reach; Especially just more improper to juvenile, child, long people's the body inclination center of gravity that causes of body could be played reluctantly, add that numerous and diverse various fortune refer to that technology makes the people lose enjoyment easily in exercise, make the learning keyboard musical instrument become dry finger gymnastic training, this also is that most juveniles, child are the major reason of not going down to numerous philharmonic persons.

Summary of the invention

The utility model provides a kind of 12 average series of sound formula keyboards, with solve present 7-5 system key take inventory complicated operation, study and play all inconvenient problem.The technical scheme that the utility model is taked is: constitute by three row's buttons, the quantity of every row's button between 7～44, each button big or small identical, every horizontal row press the whole tone scale arrangement to button, oblique button is pressed the chromatic scale arrangement.This every row's button increases progressively the height stepped appearance from top to bottom successively to be arranged, and this highly is 0.3～0.5 centimetre.Button adopts circular.

Advantage of the present utility model is: the keyboard array structure novelty has used hand shape and has not carried the baby, the little advantage that is not subjected to obstacle of hand.Play the 6 or 7 degree intervals that octave only is equivalent to conventional keyboard, make the most of philharmonic person of finger condition deficiency obtain liberation, can select any song that in the past can't make inquiries to play.And this keyboard is short and small, and elastic force is good flexibly, particularly is fit to low age child and children study.Because of keyboard is plane, similar keyboard for typewriting will be better than the traditional type keyboard so play fireballing melody, can reach the speed of stringed musical instrument.
