Such a combination As a result, there are both national musical instruments and Western musical instruments in the overall national band, which cannot be called a pure national musical performance.

In order to realize that the national band can use all national musical instruments to complete the performance without mixing western musical instruments, the performers of the band also chose Gehu as the bass instrument of the band, but the performance effect is still not up to the effect of pure national musical instruments. Mainly for the following reasons:

Gehu is improved on the basis of Erhu. It is a new type of stringed instrument played like a cello. The upper part of Gehu is like a cello, and the tube of Gehu is like an Erhu tube. This design cannot be used in playing. Huqin-like stringed instruments have national characteristics such as pressing and kneading strings, and lack the timbre of the cello's bass range, and its range is between the middle hu and the cello; In this way, players of huqin instruments cannot play. Therefore, lack of practical application significance, the band finally chooses cello instruments.

In the huqin family of national musical instruments, huqin instruments are composed of two strings. The difference from Western instruments such as the cello is that huqin instruments have no fingerboard. Playing, the player presses the strings with his left hand and hangs in the air, and holds the bow with his right hand like chopsticks or a pen. Since the bow is a soft bow, he can play different timbres and sounds by adjusting the tightness of the bow with his fingers when playing. Feature skills. As a musical instrument of a national band, it is necessary to maintain the performance characteristics and skills of these national musical instruments first, in order to achieve the requirements of consistent expression techniques and unified voices, and to give full play to the national performance characteristics of the national band.

Playing technique can be brought into full play, which solves the problem that in the past, due to the thickened piano tube, it is not convenient to play on the legs or in front of the legs or between the legs, the bow cannot be played, and the national performance technology is hindered. question.

Therefore, this bass huqin can maintain and bring into play the performance techniques of playing huqin instruments, such as the left-handed large sliding vibrato, pressing rubbing, cuddling rubbing and other national characteristic technical techniques used in the erhu type suspended stringed instruments without fingerboards, etc., can be used in The bass huqin, but the leather hu, cello and other stringed instruments with fingerboards cannot be played.

At the same time, due to the difference between the soft bow of the erhu and the chopstick-like holding bow of the erhu and the hard bow of the violin and the thing-like holding bow, there is also a big difference in the bowing skills of the violin. It is difficult to show the special color of national music in bowing.

The bow-moving skills of the bass huqin cannot be played by violin instruments. For example, to imitate the sound of ambushes, the sound of the wind, or local characteristic techniques such as Henan. Only when the bow hair pulls the inner strings and produces a hoarse and musical tone can it be expressed. However, the bow of violin instruments is played outside the strings, and it is impossible to play one string with the bow stick and the other string with the bow hair at the same time; another example is to imitate the sound of horseshoes, you need loose bow hairs to hold the strings and rub them up and down. , The violin bow hair is very tight, although it can be rubbed, it can't play the sound effect of horseshoes.

A lot of national music like this needs the performance of national musical instruments that meet the performance of national music, and this bass huqin can solve the performance requirements and skills that are difficult for violin instruments to complete, and keep the timbre of bass and double bass. The bass huqin maintains the shape and structure characteristics of the combination of two strings and the playing between the two strings of erhu and other huqins, and the characteristics of national musical instruments have not changed.

And because the material of the piano tube is made of wood, there will be no enlargement and thickening of the piano tube in the past. The outer surface of the piano tube is still made of snake skin. The snake skin will become loose due to rainy weather, humidity changes, etc. If it collapses, the timbre of the piano will be dull or there will be no technical problems. The surface of the qin tube is stable and the timbre is well maintained. The material of the qin tube is changed from snake skin python skin to wood or other materials, which is more environmentally friendly .

And because the shape of the piano tube is designed in the shape of "8", the shape of the piano tube can be made larger. The concave part in the middle of the "8" shape can be easily placed between the operator's legs and play easily. The "8" shape The layout of the supporting tuning board inside the design can achieve various sub-bass reverberation effects, and at the same time make the huqin achieve the effect of a sub-bass huqin.
