Description

Double-row thumb piano easy to play

Technical Field

The invention relates to the technical field of music equipment, in particular to a double-row thumb piano easy to play.

Background

The thumb piano is a national musical instrument with national characteristics in Africa. In different african countries, the Thumb instrument has different names, for example kalibba is the kenia name for this instrument, whereas zimbabwe is called Mbira and congo is called likmbe, with Sanza and Thumb pinano. It is mainly named because the thin sheet (mainly made of wood or bamboo, and also made of metal in modern development) on the body is poked by the thumb.

When the thumb piano is played, the keys are pressed down by the thumbs of the two hands and then released, and sound is produced through vibration. The musical scales of the existing thumbstick are generally arranged orderly, or are arranged from high pitch to low pitch in sequence, or the low pitch is in the middle and is distributed on the left side and the right side in sequence when the existing thumbstick walks to the high pitch; when the thumb piano is played, the problems that the distance between keys is too small, the keys are easy to touch by mistake, or the sound finding speed of symmetrically distributed musical scales is slow, and the harmony and melody are difficult to carry out synchronously exist. Therefore, a double-row thumb piano easy to play is provided.

Disclosure of Invention

The invention mainly aims to provide a double-row easy-to-play thumb piano, which forms a structure with staggered high and low tones through the distribution of two rows of scales, is convenient for finding sound during finger operation, does not generate sound mixing, is arranged in a back direction, does not generate interference with each other, can be operated and used by two persons at the same time, increases the use pleasure, has good harmony effect and can effectively solve the problems in the background technology.

In order to achieve the purpose, the invention adopts the technical scheme that: a double-row thumb piano easy to play comprises a piano key group A and a piano key group B which are arranged back to back, wherein the piano key group A and the piano key group B are respectively provided with 9 keys, the 9 keys are distributed in a staggered mode and are different in length, the piano key group A1 is arranged in the key musical scale sequence from left to right, namely D4, A4, B3, F4, G3, E4, A3, G4 and C4 in the international acoustic pitch notation, namely, the mediant 2, the mediant 6, the bass 7, the mediant 4, the bass 5, the mediant 3, the bass 6, the mediant 5 and the mediant 1 in the C-tone numbered musical notation; the key group B has the key scales arranged in the order of D5, a5, B4, F5, G4, E5, a4, G5 and C5 in international acoustic pitch notation, i.e., high pitch 5, high pitch 6, middle pitch 7, high pitch 4, middle pitch 5, high pitch 3, middle pitch 6, high pitch 5 and high pitch 1 in C-note numbered musical notation from left to right.

Further, the even-numbered keys of the key group A and the even-numbered keys of the key group B are shorter than the odd-numbered keys of the key group A and the key group B, the end parts of the even-numbered keys of the key group A and the key group B are tilted upwards and then slightly tilted downwards, and the end parts of the odd-numbered keys of the key group A and the key group B are bent downwards.

Further, the specific length of the key group A is represented by Q, and Q5 > Q7 > Q3 > Q9 > Q1 > Q6 > Q4 > Q8 > Q2; the key specific length of the key group B2 is represented by q, and q5 > q7 > q9 > q3 > q1 > q6 > q4 > q8 > q 2.

Further, the key group A and the key group B are fixed on the resonance box through connecting pieces.

Further, the connecting piece comprises a pillow A and a pillow B which are arranged below the key group A and the key group B in parallel, and a cross beam which is arranged above the key group A and the key group B and is fixedly connected with the resonance box through screws.

Further, the piano pillow A and the piano pillow B are both round copper bars, and the cross beam is made of stainless steel.

Further, the diameter of the nut A is larger than that of the nut B.

Furthermore, the resonance box is made of solid wood boards, and waist lines are arranged in the middle of two sides of the resonance box.

Further, the keyboard comprises a pitch mark arranged at the end parts of the key group A and the key group B, and the pitch mark is marked at one end, close to the poking end of the finger, of the key in a writing mode.

Compared with the prior art, the invention has the following beneficial effects:

the acoustic pitch range of the key group A1 from left to right is D4, A4, B3, F4, G3, E4, A3, G4 and C4 in the international acoustic pitch notation; the key set B has the key scales arranged in the sequence of D5, A5, B4, F5, G4, E5, A4, G5 and C5 in the international acoustic pitch notation from left to right, and a structure with staggered high and low pitches is formed by the distribution of two rows of scales, so that sound can be conveniently found when fingers operate, sound mixing cannot occur, the keys are arranged in a back direction, and interference cannot be generated among the keys.

The two rows of structural designs can also meet the function of simultaneous cooperation of two persons, the use function of the thumb piano is expanded, and the music interest experience is good;

the end parts of even-numbered keys of the three and two rows of key groups tilt upwards and then slightly downwards, and the end parts of odd-numbered keys of the key groups are bent downwards, so that the manual operation is facilitated, and more music effects can be generated by harmony easily;

the scale of four, two rows of 9 keys all does not have the law, but high bass all takes into account, under the condition that does not influence the musical effect, the user finds the sound and need not stride long distance, and the operation is used and is experienced the sense better.
