Some jinghu lovers will encounter noise problems when they play the piano. This situation should be explained from two aspects: one is the problems that may occur in the player's own performance, such as: incorrect playing posture, poor bowing angle, string wiping strength Uneven size, inaccurate pitch, there will be noise. solutions to the above problems. With the enhancement of bowing ability, the noise will be gradually overcome.

Now, I mainly talk about the noise caused by the Jinghu musical instrument itself, which is like a weapon in the hand. Its quality and quality are directly related to the performance of Jinghu. In order to become a high-level Jinghu player, it is especially necessary to pay more attention to the sound quality of the Jinghu instrument itself. That is to say: from an artificial point of view, actively do some debugging work of Jinghu, which is of great benefit to the performance of Jinghu. of.

Below, we cite several reasons and measures that should be taken to make noise in Jinghu.

When noise occurs, we first observe from the back of the bobbin to the front to observe whether the instrument maker will have excess glue overflowing the outlet when skinning, whether it adheres to the surrounding of the snake skin, when the glue is too much or too thick, this kind of The glue suspended around the leather surface will "tighten" the snake skin and vibrate the surface to generate noise. Therefore, when choosing Jinghu, it is better to choose a moderate "shrinking".

To reduce noise, it should also be noted that when skinning, the instrument maker should skin according to the actual gate. Especially in the selection of materials, it is necessary to choose the skin according to the piano. The skin is chosen for the tune. The skin is chosen because of the player's "skill" in bowing. In the Mongolian snake skin, it is very important whether the horizontal and vertical pulling force is carried out strictly according to the tune required by Jinghu. Secondly, when kneading the "skin board", don't be in a hurry, "crisp board" skin, Thick skins require double the time to knead. These processes are handled well, and the noise will be greatly reduced.

Then there is the requirement of Jinghu practitioners themselves for the Jinghu tune they use, that is, when they are skinned, they ask the musical instrument maker. After that, you can "release" it yourself. A bridge with a slightly larger chassis can be installed, and the tuning method can be adjusted to a fifth and a half-tone higher than the original tune to compress the snake skin. The purpose of this is to create a greater pressure on the Jinghu skin surface. This pressure process is actually a static running-in process for the main system of the piano and the barrel and snakeskin. Due to the different lengths of the burdens, the size of the bobbins varies. Therefore, this static running-in state is carried out according to the "string length" of Jinghu's own body. After about a week of "tight string treatment" for natural running-in, the elasticity of the snake skin will adapt to the tension and tension of its own "string length" condition. After such "releasing" treatment, the snake skin will be reduced to half or 1/4 of the tune that you need, reaching the height of the real Jinghu tune. At this time, remove the large size, replace it with a small size, and continue to test the piano. Tuning, when the door and tone, the volume reaches a satisfactory state, you can no longer press the leather every day. Whenever the Jinghu is pulled and folded, the strings must be loosened and the yard sticks to the edge of the front barrel to reduce the pressure of the yard on the snakeskin. This can prolong the service life of the snake skin in the optimal state of door adjustment. If conditions permit, epoxy resin glue and ethylenediamine can be used for curing, and the ratio of 1/5 or 1/6 can be used for curing. On the fibrous side of the snake skin, a protective film is formed. Epoxy resin is a chemical agent and is insoluble in water. That is to say, when the climate changes, when the fibrous side of the skin is not covered with resin glue, this kind of Biomass absorbs and emits water at any time as the climate changes. When the external climate is dry, the fiber-containing side will overflow with water, and the snakeskin will dry out and make noise. When the weather is humid, the snakeskin will absorb water again, so Jinghu feels stuffy. This is the influence of the external climate that has caused the instability of Jinghu's voice. Therefore, a thin epoxy resin protective film is coated on the fiber side of the snake skin, which not only prevents the release and absorption of water, but also relatively maintains the stability of the snake skin's moisture. I have used this method for many years and it works very well. It does not affect the original sound of Jinghu, and at the same time prolongs the service life of the snake skin.

It belongs to the strings; the material should be presented: to identify a good pair of strings, it depends on whether it is easy to vibrate and how sensitive it is, and the ratio of the thickness of the inner and outer strings of Jinghu. When the inner string is thin, the sound is trembling, and it is easy to make a "thief" sound, and it is easy to sound noise and overtones when it is too rough. Generally speaking, the thickness of the outer strings, such as from the perspective of hearing, is not easy to hear the quality of the sound. Only when you play it yourself, the feeling that the inner and outer strings are not "harmonious" will be clearly experienced.

The choice of the yard: the tightness of the qin qin bamboo, the quality of the bamboo, the size of the chassis, the depth and width of the groove, the slope of the qin yards, etc. all have a certain impact on the pronunciation of Jinghu. In general, a Jinghu should be equipped with at least four to five piano bridges, so that one can find a bridge that adapts to its own conditions according to the Jinghu’s own conditions. After a good string, the side with the larger slope will have an upward force when the string is tightened upward. The higher the tuning gate, the more stable the code is with the leather surface. The stability of this force point is conducive to the resonance of the body, so it is also the key to making Jinghu sound solid. Therefore, when equipping the Jinghu with the piano code, it is necessary to fully consider the height of the code, the angle and size of the bevel, and to achieve the standard that the Jinghu can emit a good sound effect. Generally, the code made from the bamboo of old mahjong tiles is very easy to use. The main reason is that the bamboo is old and grease is immersed, and the gap of the bamboo silk can be filled, which is powerful for conduction and vibration pronunciation. This old bamboo piano code is very popular among players. welcome.

Qianjin hook: Generally, brass wire or stainless steel wire is bent into a shape like the English letter S. The beautiful and elegant Qianjin hook is generally bent into a circular ring shape with symmetrical arcs on both sides. If the Qianjin hook is not rounded or the left and right arcs are asymmetrical, it will affect the parallel arrangement of the strings in the Qianjin hook and affect the performance. It is best to choose a small piece of thin sheepskin pad of about 0.6×0.5 cm in the hook-shaped arc, so as to avoid the direct contact between the steel string and the metal hook, which will produce a “steel-steel smell”. The direct contact between the string and the hook will cause damage to the "string skin", resulting in premature string breakage.

The above problems are generally encountered by Jinghu practitioners. Some problems may exist on one Jinghu, or several problems may exist at the same time. Therefore, after adjusting the noise of Jinghu, it can be placed on the Jinghu at any time. objective reality before them. In my opinion, the process of adjusting Jinghu instruments is also a process of learning. I hope that practitioners should use their brains and hands when doing this work. In order to make your piano sound pleasing to the ear, you may also try the fun of tuning the piano.
