Background

As is well known, stringed instruments in the national band are generally selected from gaohu, urheen, zhonghu, and the like, and in order to enrich the performance of bass instruments in the band, cello and bass violin are also selected, but the cello and the bass violin belong to one of the western musical instruments, and such combination results in the performance of both the national musical instruments and the western musical instruments in the whole national band, which cannot be called as pure national musical instruments.

In order to realize that the national musical instrument can be fully adopted in the national band to complete the performance, the performance of the western musical instrument is not doped, the performer of the band also selects the peucet as the bass musical instrument of the band, but the performance effect still cannot reach the effect of the pure national musical instrument, and mainly has the following reasons:

the design can not only use the characteristic skills of national colors such as string pressing, string kneading and the like of the string instrument of the urheen type, but also lack the tone color of the bass region of the violin, and the tone range of the novel string instrument is between the violin and the violin; meanwhile, the playing technique of the player uses the playing technique of the cello, so that the player of the huqin instrument cannot play, and therefore, the practical application meaning is lacking, and the band finally selects the cello instrument.

In the Huqin family of national musical instruments, the Huqin musical instrument is composed of two strings, and is different from the American musical instrument such as a violin in that the Huqin musical instrument has no fingerboard, the national playing characteristics are mainly represented by that a player plays between the two strings, the player plays in a suspended manner by the strings, and the bow is held by the right hand, such as holding chopsticks and holding pens, and different tone colors and characteristic skills can be played by adjusting the tightness of the bow by fingers when playing because the bow is a soft bow.

The violin instrument bows are pulled out of the strings, so that the bow rod can not pull one string at the same time, and the bow hair can pull the other string; for example, the horse hoof sound is imitated, the loose bow Mao Gazhu strings are required to rub up and down along strings, and the violin type bow hair is very tight, and the sound effect of the horse hoof sound cannot be played although the violin type bow hair can rub.

Many national music such as this requires the performance of a national musical instrument conforming to the performance of the national music, and the bass huqin can solve the performance requirements and skills that are difficult to be achieved by violin-type musical instruments, and maintain the timbre of bass and double bass. The bass Huqin keeps the shape and structure characteristics of the two strings combination and the pull between the two strings of the Huqin such as the two-stringed bowed instrument, and the characteristics of the national musical instrument are not changed.

Because the material of the musical instrument barrel is wood, the thickening of the conventional musical instrument barrel is avoided, the snake skin is still selected for covering the outer surface of the musical instrument barrel, the snake skin is loosened due to overcast and rainy weather, damp change and other reasons, the musical instrument code is easy to collapse, the tone color of the musical instrument is also dark and dumb or the tone cannot be produced, the surface stability of the musical instrument barrel is good, the tone color retention degree is good, and the material of the musical instrument barrel is changed from snake skin python skin into wood or other materials, so that the musical instrument is more environment-friendly.

The shape of the barrel is designed into the shape of the '8', so that the shape of the barrel can be made larger, the concave part in the middle of the '8' shape can be convenient for an operator to put between two legs, the operator can play easily, the layout of the support tuning plate in the '8' shape can achieve the reverberation effect of various bass, and meanwhile, the Huqin achieves the effect of the bass Huqin.
