The beautiful sound of the erhu must be music, why is it wrong?

First of all, this problem is common in non-fixed pitch stringed instruments, and beginners have a particularly poor voice, which is mainly due to the way these instruments are played.

Violin, erhu and other string-pulling instruments are mainly caused by the friction between the bow and the strings, and this vibration is then resonated by the top and back plate through the saddle and the sound column, so that the sound can be good. So it comes down to the shock problem. And there are too many factors that affect the vibration.

Subjective factors: force, angle, point of contact.

These two reasons can be the two main directions that affect the sound, holding the bow in the right hand at the same time to grasp the strength and angle, the force is large, the sound will explode, and the small will be empty. If the angle is off, it will scatter, and the contact point is not right and cannot bring vibration.

Objective reasons: body, strings, saddle, temperature and humidity.

There are too many points that can be said about this, such as the body is injured, the back plate of the panel is too thick, etc., or the piano saddle is wrong, the temperature is too low, the humidity is too high, etc.

Therefore, the timbre of stringed instruments can be said to be difficult to control, even if it is an expensive instrument, it will definitely not sound good when you get started with zero foundation. Strings are like that, imagine we rubbing on the ground with sandpaper, rubbing randomly, no rhythm, no dynamics is noise. If you are a percussion friend, you can play with the sandpaper and play a rhythmic rhythm.

The leather is one of the most important parts of the erhu. The thickness of the excellent skin is moderate and uniform, and the scales are neatly arranged. Horizontal and vertical rows, the black block is in the middle, the yellow block is evenly divided on both sides, the boundary is clear, the leather surface is smooth, and the scales are not warped. (International Chinese Music Cup).

1.If the leather is facing the light, if it appears dark and barely penetrates the light from the barrel, the skin will be thicker. Skin that is too thick will affect the good vibration of the resonator, making the tone dark and woody, and the volume will be low.

At this time, the barrel can be removed, with a flat-headed wooden stick, wrapped in a layer of fine water sandpaper, dipped in a small amount of water, stretched into the barrel, from top to bottom along the python fiber to gently polish the back of the skin. Pay attention to check the light while grinding, and make sure that the thickness of the leather is uniform and moderate. After grinding, wipe off the powder with a cloth, and then apply a thin layer of vegetable oil with a cotton swab.

2.If you find that the skin is too thin, you can remove the barrel and apply it to the back of the leather while it is hot with a cotton swab dipped in the dissolved wax solution, and control the thickness of the wax layer when applying. After coating, bake the leather facing the heat and let it sit flat for a while to evenly distribute the wax layer.

When baking, keep moving the barrel to avoid burning out due to excessive heat.

3.If the skin becomes too loose after long-term use, resulting in dull pronunciation, you can wrap the hygroscopic agent (such as: silica gel, fried salt, quicklime, etc.) in the barrel, which can restore the elasticity of the skin to a certain extent.

Usually after playing the piano, you should immediately put on a long stick (you can use a pencil) or remove the piano horse to reduce the time that the skin is pressed.

Barrel, stem.

The barrel and stem are generally made of hard woods such as rosewood, ebony, and mahogany, which are susceptible to the influence of the climate Therefore, it is necessary to properly adjust the humidity in the case according to the climate to ensure that the piano slip and stem will not crack due to dryness or degum due to moisture, and at the same time, it can also maintain the stability of the erhu sound quality.

1.When the climate is humid, one or two packets of moisture absorbent should be placed in the piano case; When the climate is too dry, wrap a sponge with just the right amount of moisture in plastic film, and then prick some small holes with a needle and place it in the case to increase the humidity. In dry areas, a thin layer of vegetable oil can often be applied to the barrel and stem to prevent cracking.

2.After each use of the erhu, wipe the rosin powder off the barrel and stem with a soft cloth and put it in the barrel or sleeve instead of hanging it on the wall.

3.In the cold winter, after taking the piano from the outside into the room, do not open the case immediately, but wait for twenty or thirty minutes before opening it, so as not to condense a layer of small water droplets on the piano body, so that the instrument will be damp and affect the sound quality.

Saddle. The saddle is an important conduction component that has a great impact on the sound quality of the erhu. It should be said that each erhu should choose a suitable yard for it, which needs to be determined after many trials.

The question raised by the landlord is about physics.,The other answerers are a little off topic.。。。

The sound produced by the erhu is not necessarily a musical sound, because 'the sound of the erhu making a beautiful sound may be a musical sound', and the sound produced by pulling the erhu indiscriminately is a noise.

The erhu often has a voice, which can lead to a decrease in timbre. On the one hand, the performance skills are not proficient enough, and on the other hand, it has a lot to do with the improper production and assembly of the erhu.

Here's how to remove erhu noise:

1. Find out the cracks (lines) on the wood and the gaps caused by mistakes in production, and use gluing and other methods to eliminate the source of "penny breaking effect".

2. Eliminate the stress of the piano skin. For new pianos with excessively tight skin and uneven skin tension, you can use a soft cloth from top to bottom from edge to middle, and rub it with proper strength for a few minutes, once a day, for a period of time, which has obvious effects.

3. Choose the right sound pad. Adjust the height and size of the sound pad material and choose the best. It is usually better to use pure wool tweed, velvet and felt thick fabrics.

4. Choose the right piano saddles. The material, chassis size, height, and width of the string groove should be appropriate, and the noise reduction effect of the turbate code with moderate vibration conduction is usually better.

The reason for the erhu noise, in addition to the improper production and accessories of the erhu, is that the speed of the bow movement and the strength of the bow pressure do not match. For beginners, this is the key to remember: in addition to the speed of the bow must be uniform, the strength of the bow must also match the strength of the bow, otherwise it is very easy to make noise.

This is the reason why beginners who are learning erhu often produce "rattle, rattle" noise even if they are good erhu. At this time, it should be noted that the slower the bow movement, the less force the bow should press; If the force of the string is high, the bow must be pushed and pulled quickly.

In addition, the strength of the bow and the bow should be small when playing, and the change of strength and speed in the whole bow movement process is an olive shape with two small ends and a large middle: the bow movement speed at both ends is slow, the force of pressing the string is small, the middle force is large, and the bow movement speed is fast; The stronger the play, the greater the amplitude ratio between the two ends and the middle, but the process of going from weak to strong is very short, but it cannot cancel this change process.

In addition, a sponge, flannel, etc. is placed under the strings on the lower side of the saddle to suppress the vibration of this part of the strings, which can effectively suppress the noise of the erhu.

If the erhu wants to play a good timbre, it mainly relies on moving the bow and pulling more empty strings.

It is mainly a matter of right-handed bow movement It is necessary to pay attention to the horizontal movement of the bow and the bow hairs close to the strings If there is noise, it should be corrected at any time!

Summary. Hello, happy to answer for you.

1.New piano. Any new piano needs to be run-in, and if the run-in is good, it will slowly sound better, and if the run-in is not good, the sound may be better if the time is extended, but it may also be a problem with the piano itself, so it can only be used first.

2.The parts of the piano need to be adjusted appropriately. For example, whether the elasticity of the jack tie is appropriate; The jack is a little farther away from the saddle; The strings are changed frequently; Saddles, the size and position of the pads and many other aspects will affect the timbre, so you need to adjust it according to your own situation.

3.Improper use of the piano, or not enough care of one's own piano. For example, after practicing, the strings are never loosened; The piano is not placed in the piano box, but in the display case, whether it is dry or wet, do not pay attention to the erhu,; Never wipe the erhu, rosin-stained bow rods, piano rods everywhere.

These bad habits can also lead to an unpleasant erhu sound.

Why does my erhu sound bad?

Hello, happy to answer for you. 1.New piano.

Any new piano needs to be run-in, and if the run-in is good, it will slowly sound better, and if the run-in is not good, the sound may be better if the time is extended, but it may also be a problem with the piano itself, so that it can only be used first.2Each part of the piano needs to be properly adjusted. For example, whether the elasticity of the jack tie is appropriate; The jack is a little farther away from the saddle; The strings are changed frequently; Saddles, the size and position of the pads and many other aspects will affect the timbre, so you need to adjust it according to your own situation.

3.Improper use of the piano, or not enough care of one's own piano. For example, after practicing, the strings are never loosened; The piano is not placed in the box of the piano cavity, but in the display case, and the erhu is ignored whether it is dry or wet; Never wipe the erhu, rosin-stained bow rods, piano rods everywhere.

These bad habits can also lead to an unpleasant erhu sound.

The most important reason for the bad sound of the erhu may not be the problem of the qin, but the performance level of the owner of the erhu. The performance level is high, and the energy of the erhu can be transmitted to the Hu Wang, so that every part of the piano is in the best condition, and when combined together, it produces a wonderful timbre. And the level of performance is not good, you can't control the piano, even if the piano is good, it will be very mediocre in your hands, and the same piano, the sound in the hands of the master may be different, this is the problem of people, not convinced.

The status of the erhu in folk music is basically the same as that of the violin in Western music. Both have a timbre close to the human voice, and both are stringed instruments. However, due to the different sizes of the case and the different design of the sound column, the timbre of the two is different.

As for the sad sound of the erhu, the resonance of the barrel is a reason, the timpane of the inner and outer strings is a reason, and the beggars of the street are also a reason. Since the Tang Dynasty was introduced to the Central Plains, the huqin has continued to find today, which also makes the erhu have a sense of history. The beggars on the streets and alleys also give people a bleak perception of the erhu as a musical instrument.

In addition, the traditional repertoire of erhu, including Erquan Yingyue, rivers and rivers, etc., either depicts a bleak life or is based on historical tragic stories, which makes the interpretation even more vicissitudes. What's more, there will be some techniques to deliberately aggravate these feelings, such as river water, there will be a technique of pressing and rubbing the strings, so that the sound of the piano is similar to the effect of choking.

In fact, erhu can have a lot of new understandings. You can learn about the understanding and creation of some foreign people's understanding and creation of not only erhu, but also Chinese folk music, which is not limited by traditional thinking in China. For example, a series of works by Jia Pengfang, an erhu player in Japan.

There is also a piano and erhu ensemble by Yukiko Isomura and Masao Sakashita - "The Street Where the Wind Lives". This song is good to listen to and good to pull and have good ideas, in the next favorite, I recommend it to you.
