How to maintain the erhu and how to maintain the erhu

The best way to maintain it is to take it out every day and pull it for a while, to tell the truth, I used to practice erhu every day, but then I didn't practice, the strings will rust, the bow hair will break, the main thing is to play rosin and moisture is the most important.

You just need to remember this sentence downstairs, put some mothproof tablets when the erhu is not in use, put some desiccant in areas with high humidity, and often take out the erhu to breathe.

In fact, you don't need to take too much care, rub the rosin when you don't have rosin, just wipe the rosin powder left on the barrel in time, and wipe it with a slightly moistened cotton cloth. I'm also a student of erhu!!

The skin is prone to collapse when it is wet, so it is important to prevent moisture. Erhu should not be hung on damp earthen walls, and be more careful in rainy days and during the rainy season. When not playing, you can use pencils and chopsticks to cut off a long yard and place it horizontally on top of the saddle to reduce the pressure on the skin.

The length of the long yard is as long as the diameter of the barrel and the height can be slightly shorter than the saddle. The long yard can also be used when practicing in a low voice. If the leather has collapsed, it should be remedied in time.

You can remove the saddles, dip your fingers in cold water and wipe them on the skin, let it dry overnight, and wait for the skin to dry and return to flatness the next day. It should never be dried over fire or exposed to the sun. If the leather is too dry, you can rub a little cooking oil and lubricating oil on the inside and outside of the skin.

After the bow is used, the screws on the bow shaft should be relaxed in time to maintain the elasticity of the bow shaft. When hanging the bow and taking the bow, it is necessary to prevent tearing off the bow hair, rub the rosin frequently (seven or eight times back and forth is sufficient), and do not touch the bow hair with your fingers. When the bow hair is dirty, it should be washed with soap and hot water, and you can also use alcohol cotton to scrub the rosin scale stuck to the bow hair and string.

When using the bow hairs for the first time after washing, you should take a small piece of rosin and grind it into powder, and rub the bow hairs in the broken rosin to make the bow hairs stick to the rosin inside and outside. The horsetail will become smooth after a long time, and the rosin will be taken off soon after rubbing it, making it difficult to carry the bow, so it is time to replace the ponytail with a new one.

In fact, you don't need special maintenance, just pay attention to moisture and don't let the sun shine.

Hello! My erhu was accidentally exposed to the sun, and now there is a rustling sound when I pull the empty strings, and there is no sound of the strings, how can I recover?

Take a dry cloth and wipe the rosin every day! (I also learned erhu).

The correct way to take care of erhu skin is:The maintenance of the erhu leather is actually very simple. I usually put a handkerchief in the piano case, and every time I finish pulling it, I use the handkerchief to wipe off the rosin that has splashed on the python skin

After a long time, if the erhu leather is indeed stained with some rosin, don't worry, you first gently take off the saddle and cushion, and then spray the python skin with floor wax or dashboard wax, gently wipe it with a soft cloth, and after ten minutes, the erhu skin will be as bright as new. In order to better protect the python skin, you can rub some petroleum jelly on the python skin in the dry season of winter and spring.

In order to do a good job of maintaining the piano leather, it is necessary to have an understanding of the processing technology of the piano leather. Generally speaking, the first process of leather processing is to shovel the skin, and the purpose of shoveling the skin is to remove the meat and debris that stick to the skin. The second process of leather processing is the skin, the purpose of which is to stretch the python skin and remove the oiliness from the python skin.

There is a scalding process in the leather sleeve process, which is used to stabilize the shape of the leather and increase the gloss of the skin. The third process of leather processing is skinning, and the requirements of skin are to achieve uniform hexagonal and proper tightness of the skin.

If the erhu leather is properly maintained, it will have a long life, provided that it is used regularly, and most of the erhu we see are improperly stored and damaged due to infrequent use. Regular use will keep the leather elastic, which is also its vitality, and we exercise regularly, the body is good, the timbre of the instrument is constantly used, is pulled out, do not pull it will not be good, in the case of usual use, itself is also a kind of maintenance and maintenance of the instrument. The right use is also the right care.

There are many theoretical books or knowledge on the Internet that suggest some methods for maintaining and handling the piano skin, but there is a gap between theory and practice after all, and sometimes the gap is not small.

I will talk about some knowledge of erhu leather maintenance from the aspect of erhu production. Taking Wanchun Erhu as an example, the first process of the piano skin is to shovel the skin, the purpose is to remove the meat and debris stuck to the skin, and the shovel skin should be even, just right, which is a very critical and tiring process. The second is the skin, the purpose is to stretch the python skin, to remove its oiliness, the molding is stable, at this time there is a key process is to hot the skin, the purpose of the hot skin 1

It is to stabilize the skin and prevent the stereotyped skin from shrinking again. 2.It is beautiful, and the leather is shiny.

3.Protects the leather from humidity. Once the cover is complete, you can decide how to use the leather.

The third is the tartan leather, the first two processes are done to pave the way for the tartar, so that the hexagonal uniformity, the tightness is appropriate, the difficulty is the matching of the leather and the piano barrel, according to the situation of the piano leather to deal with the piano barrel, according to the wood selection of the piano skin. From these processes, you can know that there are two points:1

Oil-free, oily skins can seriously affect pronunciation, and looking at the light feels like a drop of oil on the paper. 2.The surface of the leather has been treated.

My grandfather, Zhou Rongting, pioneered the process of setting the skin and reforming the python skin. The processing of these processes will play a key role in the timbre and use of the erhu.

In daily use, there is no need to oil the skin, apply petroleum jelly, etc., and there is no need to seal wax on the back of the skin, and it is normal for the scales to be warped, and the rolled scales vibrate with the skin. And it can not be glued, the leather should maintain its breathability, naturalness, it will naturally adapt to the use of the environment, so the erhu does have its aura. If the inside and outside of the skin are sealed, it will affect the vibration of the skin.

Do not reprocess the back of the leather after it has been tampered, because scraping or grinding the back of the skin from the back of the barrel will cause the skin to be unevenly thick, which will cause the skin to crack, so I recommend that you do not try it. The change of timbre should start from the strings, saddles, daughters and pads, and you can repeatedly adjust and adjust the ideal timbre to your satisfaction if you know their functions and principles.

Put some mothproof tablets when the erhu is not in use, put some desiccant in the humid area, and often take out the erhu to breathe.

1. Piano skin. The maintenance of the erhu skin is very important to maintain the tone of the erhu, and it is also the most important concern of every erhu player. If the erhu leather is well maintained, it will have a long lifespan.

Most of the erhu we see with damaged skin is caused by improper storage and infrequent use. If the erhu is often used, its skin will maintain a certain elasticity, and the pronunciation quality of the erhu will be relatively stable. The timbre of the erhu is slowly pulled out in continuous use, and the regular use of the erhu is a good maintenance and maintenance of the erhu.

2. Barrel and stem.

The barrel and stem are mostly made of hard woods such as rosewood, ebony, and mahogany. Hardwood, on the other hand, is susceptible to the influence of climate, so the timbre of the erhu has a certain relationship with different climatic conditions and air humidity.

Hard wood has a compact density and delicate texture, which will cause an imbalance of internal and external stress in the environment of one dry and one wet or one cold and one hot, and in serious cases, it will cause cracking of the barrel and stem.

If the erhu is in an excessively humid environment for a long time, it will also cause the degumming of the barrel and skin. In order to avoid the occurrence of the above situation, the piano should be put into the piano case when not practicing, and some desiccant should be put in the piano case.

3. Bow. During the use of the bow, do not touch the bow hair with your hands, so as not to stain the bow hair with oil after a long time and affect the performance. Once you find that there is a lot of oil stains on the bow hairs and affect the performance, you can remove the bow hairs, wash the bow hairs in clean water with soap, dry them and rub them back with rosin before using Minbi.

After each playing, the bow hair should be relaxed to restore the bow rod to the normal shape of the bridge posture, otherwise the bow rod will be deformed after a long time, affecting the performance of the bow. If the bow does not need to be placed in the case for a long time, some mothproofing agents should be placed in the case to prevent the bow hair from being bitten off by moths.
