How to take care of the erhu when you don't play it for a long time?

1. On the question of whether or not to loosen the strings after each play

We know that when we tune the baby's inner and outer strings to the standard tone, the gauge will produce a relatively large pressure on the skin, and if we don't loosen the strings to reduce the pressure for a long time, the place where we place the gauge will appear to be concave after a long time, which affects the normal articulation of the erhu, and some of our friends like to use a similar pencil to spread the tension of the strings to both sides of the barrel to solve the problem of every time we calibrate the erhu. Some friends like to use a pencil-like object to spread the tension of the strings to the two sides of the barrel to solve the trouble of each time you calibrate the strings, but this is not a good method, because the pressure of the code on the skin of the instrument is reduced, but the tension of the strings on the axle will increase, and at the same time the tension on the instrument pole will increase, and in the long run, the instrument pole will be deformed. This problem, I have repeatedly consulted some Erhu masters, after playing the instrument to loosen the strings is the unanimous answer, in fact, regular proofreading of the strings can also cultivate our hearing and patience, but have to be equipped with a good point of the proofreader, now the market is too much colonial sound, choose your favorite on the line, if there is no proofreader temporarily do not be in a hurry, there is a landline phone can also be a fixed telephone, the proofreading of sound before the landline phone by pressing the hands-free. Before tuning, press the speakerphone of the landline, and the sound it sends out will be the pitch of the outer string A we want to tune. (Note: If it is a new instrument, you can not release the strings, because the new instrument skin tension is very large, do not release the strings for a period of time to accelerate the opening of the sound, it is recommended that no more than one month)

2. On the erhu moisture-proof, anti-insects and shockproof

Talking about the moisture-proof first, the erhu's skin is an animal protein, the skin of the piano skin is more susceptible to the temperature, the impact of moisture, especially humidity, which is what many friends This is the reason why many friends often talk about their babies, sometimes the tone is good, sometimes the tone is not good, the general piano skin is relatively loose baby, encountered clear and dry weather tone will become much better than the original, and some of the piano skin is relatively tight baby encountered cloudy and humid weather will become mellow, sweet. This is because the skin is affected by temperature and humidity. We need to use the natural temperature and humidity to our advantage and use different instruments for different weather to get the desired results. However, it should be noted that the baby must not be placed in the air-conditioned room to save, because air-conditioned room air humidity is too small and too dry, as well as especially in the south, every year there will be a rainy season, be very careful to moisture, if the skin of the piano is seriously damp, it would not be good to do. The erhu should not be kept in an air-conditioned room. Regarding moisture prevention, we can place desiccant (usually sold in supermarkets) in the baby's box near the barrel to absorb moisture.

Anti-bugs: This is especially important to note, we sometimes eat, hands are not washed, on the violin, which will be some food residues and oil substances stained to our baby, but also these substances are the bugs like food, when the baby put in the box, some small bugs may be from the outside of the box to climb to the baby on top of the worst is to your piano skin to bite through, then our baby will be scrapped. The baby will be scrapped. So every time we play the piano, we suggest that we should wash our hands clean, don't have food around when you play the piano or temporarily put the piano, it's better to remove the rosin on the top of the piano skin and barrel with a clean soft cloth after each play, if not removed in time, it may not be able to go out in a long time, especially the top of the piano skin if it is contaminated with too much rosin, it will also affect the pronunciation. If you don't use the instrument for a long time, it's better to put a piece of mothballs in the box, if it's not packaged, you can wrap it with a cloth and put it in the box, which is a line of defense against insects. (If you play every day, generally do not have to put camphor)

Shockproof: This is the easiest to do, often heard that so-and-so's Erhu head and fell off, which is due to the usual reasons for carelessness, if not accidentally fall a little bit, generally all right, if often do not pay attention to, that baby is finished, remember that even the best of the baby can not afford to fall, and usually to develop a careful habit of shockproof. Do you know how much the ordinary ceramic bowl of the Song Dynasty is worth? Let's just say that this ceramic things a fall on the bad, it can be intact and preserved until now, more than a thousand years, it is too difficult!

3. String Maintenance

If you loosen the strings every time you finish playing the instrument, the service life of the strings will undoubtedly be prolonged, but sometimes the air humidity is relatively high, and the strings will rust once they are exposed to moisture, especially the strings on the upper part of the qianjin and on the upper part of the zither code, which are usually not touched by the fingers and are very susceptible to rust, and the strings can't be used if they are rusted. In order to prevent the strings from rusting, we can use a clean soft cloth to wipe these positions clean every time we finish using the baby, and the effective strings need to be wiped as well. Once the baby pronunciation abnormal or inside and outside the same point of the string position is not pure no degree of relationship, even if the string is not rust, but also should change the string, generally in order to ensure the uniformity of pronunciation, it is recommended that the best at the same time to replace the inside and outside of the string.

4. Bow Maintenance

The bow of the erhu is the most easily consumed, and the hairs of the bow will break if you are not careful, so you need to be careful. It's a good idea to relax the bow after playing, but don't relax it all the way, as this will cause the bow hairs to get messy and break easily. Also, don't get oil or food on your bow, as this may affect your playing and make it difficult to store. You should also pay attention to rosin the bow, if the bow hair is seriously lack of rosin, it will become very brittle and easy to break. This is very important, rosin on the degree should also be grasped, too much on the bad, too little on the ineffective. This depends on our usual experience to guide.

5. Anti-bow hair breakage and rosin contamination of strings and rods

We usually don't remove the bow from the instrument after playing, because it's too much trouble to hang it directly on the axle, which will lead to rosin contamination of the strings and rods, and the strings are often pinched to break the bow hair. Every time you play the instrument, you have to clean it carefully. If you don't clean it, once your fingers or tiger's mouth are stained with rosin, it will be very difficult to wash it, which will seriously affect your playing. In order to effectively avoid the occurrence of these situations, I tried to use artificial leather to do a protection, after the use of the piano to the strings, rods, along with the gold wrapped up into the case, the use of the piano when the bow is removed, and then remove the string cover, after the school sound can be played directly, so that the rosin on the top of the bow will not be contaminated with strings and rods, and strings are rarely pinched off the bow hair, I called it the "string cover". I call it a "string cover", which is both beautiful and durable, and a string cover solves a lot of problems.
