What is the purpose of adjusting the tightness of the erhu

The amplitude determines the volume of the sound, and adjusting the tension is to change the vibration frequency of the string and change the tone.

Summary. Erhu pitch change only requires fingers to move the position, and the maintenance of the erhu leather 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 seen with damaged skin is caused by improper storage and infrequent use. The skin of the erhu that is often used to make it 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.

Tips: 1. Erhu is generally set by the relationship between fifths, such as (d1, a1, c1, g1, g, d1, a, e1) or (e1, b1). 2. When playing music or opera with certain local colors, in addition to the fifth-degree relationship of the fixed strings, there are also pure fourth-degree relations.

In some sessions, there are even octaves.

How to change the tone of the erhu.

Hello, the erhu pitch change is as follows:

Erhu pitch change only requires fingers to move the position, and the maintenance of the erhu leather 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 seen with damaged skin is caused by improper storage and infrequent use.

When playing music or opera with certain local colors, in addition to the fifth-degree relationship of the fixed strings, there are also pure fourth-degree relations. In some sessions, there are even octaves.

Dear, you have to understand the relationship between the erhu's timbling, toning, and stringing, the same open string pitch and different keys determine the difference in string style (i.e., fingering). For example, if you set the pitch of the empty string to the standard pitch (i.e., d--a), if you play a piece in the key of d, according to the concept of the first key of solfège, 1=d,..5=a, so the fingering is 1--5 strings.

In the same way, if you want to play the G key, you can calculate that it should be 5-2 strings. And so on for other keys.

Summary. Need.

After the erhu is finished, the strings need to be loosened. 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 use.

Do you want to loosen the string after the erhu is finished.

It needs to be loosened after the erhu is played. During the use of the bow, do not disturb the bow hair with your hands, so as not to stain the bow hair with oil and affect the performance after a long time. 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 use.

Take a look oh kiss.

Still have any questions.

Identification method of erhu skin tightness:

When the erhu is used at a certain stage, some pianos will appear too early or too late to loosen the skin, and this phenomenon will appear in two different states:

In the first state (the skin collapse state), the skin is looser than when the new piano is used, the sound is dull and low in the barrel, and the volume is also small and weak, this sound state is the phenomenon of the skin collapse.

The second state (the natural relaxation of the piano skin), the piano is loosened after a period of time, but the volume is not weakened, and it is more mature, mellow and heavy, which is a normal opening state from an unfamiliar sound to a mature sound.

The reasons for the collapse of the piano are different, and some new pianos will collapse in less than half a year, which is caused by the following reasons:

1. The humidity of the barrel wood is large, and the barrel gradually dries and shrinks after a period of time, resulting in the collapse of the skin;

2. The preparation before the skin is not in place, such as the leather needs to be tarned many times before the skin, and the skin is fully stretched, if the skin is stretched well, the tightness of the skin will be more stable and durable, so cutting corners before the skin is also an important reason for the collapse of the skin;

3. The loose skin of the piano skin causes the premature collapse of the piano skin.

Put the erhu skin next to one ear and play the erhu skin with your index finger, the elastic and neat will be very crisp, if it is loose, the tone will be very dull. However, the humidity of the surrounding environment also has a great impact on the timbre of the erhu, so it is best to pick the piano if the weather is better.

The skin of the erhu is the skin of a large snake (python), and it has a good sound resonance effect when it is covered on the erhu. When the leather is tight, the saddle is pressed against the leather, and the shape of the leather is still flat. If you loosen it, it will sink, and the pronunciation will not be loud, and it will be sullen.

In addition, the erhu should not be protected from moisture, which will also cause the erhu to loosen its skin, and it cannot be exposed to the sun, which will deform when exposed to the sun.

FYI.

1. Visual method. Observe the front of the skin, the skin with square scales, the size of the scales is uniform, the skin with vertical scales, the spacing between the scales is relatively large, observe the reverse side of the skin, the inside of the barrel, the color of the skin is whitish and opaque, indicating that the fiber layer has been opened.

2. Shiatsu method. With your ring finger or little thumb, press the python skin to feel like it is pressed on a 2 mm steel plate. Hard and resilient.

3. Listen to the pitch. Plug the two holes in the barrel with your finger and flick the leather surface with the other finger so that the sound reaches around B4 (493Hz).

First, you can gently tap your hand to listen to the sound.

In addition, you can see the thickness of the skin through the light.

Summary. Method: Read step by step.

Loosen the outer strings first, and loosen them until they are as high as the inner strings, that is, they are lowered to d.

Loosen the inner string again until the tone difference from the outer line is 5 degrees, that is, it will be lowered to g.

The next time you use the instrument, do it upside down: the inner string rises to the same height as the outer string; Then raise the outer chord to A.

After loosening the strings, as long as the pins are not loose, 6

After tightening the string, I give the erhu the operation process of loosening the string, the inner d and outer a remain unchanged (there is no absolute in the world).

The advantage is: in the process of loosening the strings and tightening the strings. It can improve the ability to distinguish the pronunciation characteristics and pitch characteristics of the inner (thick) and outer (thin) strings; and improving the ability to listen to pitch.

Can the strings of the erhu be adjusted tightly?

Method Step by step reading 1 6 first loosen the outer strings, loosen to the same height as the inner strings, that is, descend to the inner strings, and then return to loosen the inner strings, loosen to the difference of 5 degrees with the outer line, that is, to the next time you use the piano, and operate it upside down: the inner strings rise to the same height as the outer strings; After raising the outer chord to reach the loose string, as long as the string shaft is not loose, the operation process of the method I give the erhu to loosen the string after the string is tightened on 5 6, the inner d and outer a will remain unchanged (there is no absolute hunger in the world).

Hope mine is helpful to you.

Have a great day.

If the skin is too tight, you can use a cotton swab dipped in a small amount of vegetable oil to apply to the back of the skin, then lay the barrel flat, put a 3 cm square piece of wood on the skin, and then apply 10 to 15 kg of pressure on the block, and remove it after 12 hours; If you are still nervous, you can repeat it several times. and Annihilation.

It is also possible to call the key without unloading the piano horse after playing the piano, and set the string to be two degrees taller, and so on.

One or two months. You can also lay the piano flat on the table, dip the thumbs of both hands in a small amount of vegetable oil, and press the piano skin vigorously in the direction of the scales, every day.

Once or twice, until the skin is moderately tight. However, artificially accelerating the process of fluffing the piano skin is always better than natural softness in terms of sound effect, and it may also cause some damage to the piano skin. Therefore, if it is not a last resort, it is better to let the leather change naturally during use.
