What are the effects of the erhu bottom to the erhu sound quality?

The sound quality of the erhu may not be simply measured by "good" or "bad", and there are various degrees of good or bad sound quality. For example, some pianos have a very pure pronunciation without the slightest noise, some pianos have a lot of noise and are very large, and some pianos have noises, but they are relatively less and smaller.

Many Hu friends have this experience: carefully adjusting the jack can make the noise of their erhu smaller, smaller, or even completely eliminated! That is to say:

The sound quality of the erhu can also be changed.

The influence of erhu base support on the sound quality of erhu is mainly reflected in the following aspects:

1.Resonance effect: The bottom bracket of the erhu can effectively enhance the resonance effect of the erhu. When the bottom of the erhu is in contact with the bottom bracket, the bottom bracket can act as a reflector for the sound waves, reflecting the sound waves back to the barrel, making the erhu more volatile and louder in tone.

2.Timbre: The material and structure of the base bracket also have a certain influence on the timbre of the erhu.

3.Stability: The design of the base bracket can also affect the stability of the erhu. A reasonable bottom bracket design can make the erhu more stable during use, reduce noise and vibration during playing, and improve the performance effect.

Therefore, when choosing an erhu, you can choose different brackets according to your individual playing needs to get the best sound effect.

Summary. Hello, it is a pleasure to serve you. In the absence of a base bracket, the erhu needs to be fixed by other means, and some special racks can be used to support the erhu in order to hold the strings in the correct position.

The shelves that are usually used are erhu brackets, and some are also called erhu clips. When installing the strings, you need to place the erhu on a smooth surface first, then pass each string through the corresponding string hole in turn, tighten and adjust the string length and pitch, and then clamp the string in the correct position with a clip. The clamp needs to be tight enough to prevent the string from slipping, but not so tight that it doesn't damage the string or erhu.

The bottom of the barrel is hung to **, and the stem is not hung thickly.

The clamp needs to be tight enough to prevent the string from slipping, but not so tight that it doesn't damage the string or erhu. Without a base bracket, it will be more difficult to install the second side slider, which may require more skill and patience.

But as long as it is done properly, the erhu can still be used normally.

1.Adjust the stem size: Slim the stem to fit the barrel size.

This requires some manual skills and specialized tools. 2.Replace the thinner stem:

If the stem is too thick to hang under the barrel, consider replacing it with a smaller diameter stem. 3.Replace the hook:

Some erhu string hooks can be slightly adjusted to fit different sizes of stems, and you can try changing to one that fits.

The improvement method of pulling erhu with noise is as follows:

2. The posture is correct, but the bow movement is incorrect. The direction of the bow should be perpendicular to the strings and close to the stem, regardless of the direction of the bow hair should always remain in the same straight line, and the traces on the rosin are a straight line, not a pair of top angles, that is, as the jargon says [a line that will be pulled, a large piece that will not be pulled];

If there is a murmur, it is usually related to the strength of the bow. When you first start learning, the teacher will tell you to move the bow flat, use even force, make the bow stick tightly to the strings, pay attention when changing the bow, avoid sudden force, and don't touch the snakeskin with your fingernails when pressing the strings. When kneading the strings, don't increase the pressure on the strings with your fingers, and don't forget the hand that pulls the bow at this time (not the right hand in case of left-handedness), so that the bow touches the strings inside and outside at the same time.

3. The above two have been done, but the force is too large, and it does not cooperate with the bow speed, and the slow bow is most likely to cause noise. The correct bow movement is not to add the force of the top chord to the bow, that is, not to add force perpendicular to the bow shaft, but to change the volume by the bow speed.

Three o'clock to do a good job of pulling the erhu will not be noisy:

1.Carry the bow. When it comes to bow movement, what seems like a simple action is indeed the most important part of erhu practice that cannot be ignored, and it is the foundation of right-handed technique.

The quality of the bow movement technique will directly determine the quality of the erhu timbre, and it is also a measure of a player's pursuit and control of the process. As the saying goes, "A line will be pulled, not a large piece." "Many practitioners face boring movements and monotonous sounds, and a few hastily pulls are regarded as training, and over time, the problem of erhu bow movement cannot be fundamentally changed.

In addition to enhancing their own artistic accomplishment, professional performers need to be affectionate before sounding, strong but not dry, weak but not weak, repressive and frustrated, and free to retract and release.

The bow of the erhu is different from that of the cello, and the bow hair is sandwiched between the two strings, which greatly reduces flexibility. Erhu has its own unique method of moving the bow, so it takes a lot of hard work to get it. When playing weakly, the force must be reduced and the bow speed must be slowed down; When playing strongly, the strength of the bow should be appropriately increased and the speed of the bow should be accelerated.

No matter which bow technique is used, it is necessary to make the bow straight and straight in operation, and master the running angle, otherwise it will directly affect the quality of pronunciation.

2.Press the fingers of the left hand correctly.

When we master the perfectly balanced playing posture, the natural and relaxed way of holding the piano, and the correct erhu and bow movement, we can easily play a pure and beautiful sound with regular vibrations on the open strings. But once our fingers are pressed to the strings, the sound on the erhu will be a different matter. A wrong tension will cause the string to vibrate incorrectly.

The condition of fingertip touching the strings when playing the erhu strings is crucial to the pronunciation of the erhu, and the accurate, sensitive and elastic fingertip touching action is an indispensable condition to ensure the quality of the erhu pronunciation.

3.The rhythm of the left and right hands is the most basic requirement. This requires us to control the movements of the left and right hands at a predetermined rhythmic point.

However, when we first come into contact with the coordination of the two hands, the first thing that often comes to mind is the rhythm problem. This requires us to first develop a sensitivity to rhythm and be our own doctor in order to detect problems in time at the first time.

If you are not sensitive to your own problems, you can ask your teacher for help. Of course, there are still many ways to help you discover without a teacher. For example, if you record your exercises on a tape recorder and listen to them, you will find problems that you don't usually find.

You can even use some specialized software to assist you in analyzing your own exercises.

The technique is convenient, practice the longbow more, train the strength of the left hand to press the string, and the evenness and stability of the strength of the right hand to carry the bow. Objectively, the erhu should be good, and the erhu made of just two pieces of wood and bamboo must be noisy. The rosin should be sufficient, the saddle and cushion must be put in place, and the erhu body should not be too dry.

If the ambient humidity is kept at about 60 degrees, there is no problem with the erhu.

String threading: Thread the inner string first. Steps:

Take the thicker string. There is a loop at one end and a wire wrap at the other. Put the end with the buckle into the hanging post under the barrel, pull it through the groove near you, and then pull the end with the winding wire to the top of the pin, and thread the string head into the small hole of the shaft.

It is advisable to show a millimeter or two on the other side. Then turn the chord in a clockwise direction with your left hand. The right hand is pulling the string as tight as possible at the same time.

Wrap around the outside of the hole as much as possible. Tighten slightly.

Then the outer string is installed, which is the thinner one. Hang the strings from under the barrel first. Then pass through the bow, pay attention, when wearing the bow.

The bow head, which is the end with the screw, is on the right, and the bow hair rests against the stem. When threading the pin, be careful that the winding direction is opposite to the inner chord. It should be turned counterclockwise.

Just tighten the strings slightly.

Wrap around the jack: Find the location of the jack first. Generally positioned like this:

Hold the body upright. Place the elbow of your left arm flat on the barrel. With your forearm straight up, close to the stem, draw a mark on the position of the stem in the middle of your little thumb.

This is where the jack is. Then you can go around the jack. First, wrap the jack rope on the stem two or three times, and press the rope head tightly inside.

Then make a circle around the string and then around the rod, and then set the distance between the strings. Generally between the rulers. Then it winds from the outside of the string, then from the rod, and then from the outside of the string, at least more than four times around the string.

Make another two or three turns around the rod. And just press the end of the rope inside.

Pad filter: Raise the string a little higher with your left hand, press the felt sheet or sponge pad between the string and the skin, and the leather ** is lower and higher.

Ann yard: Raise the string a little higher with your left hand, and pinch both sides of the yard with your right index finger and thumb from behind the string. Slide the bottom of the round head close to the leather and the edges and corners against the strings, and slide down to the middle of the leather or slightly up to 1-3 mm.

Timpani. Use the special timpani for erhu to set the tone.

Adjust the tightness of the bow hairs appropriately.

OK, you can try pulling.

Rub it several times the first time, and be careful not to touch your hands with the bow hair every time you rub the rosin. Don't stick rosin on the strings, if your hand touches the bow hair, it is easy to get the fat on your hand on the bow hair. In this way, you can't rub the rosin, and you can't make a sound.

If the string is stained with rosin, wipe it off with a cloth in time.

Also, be careful to wipe the barrel, strings, and lower part of the stem with a soft cloth after each play. And use a small square cloth 40 cm square. The middle of the strings of the strings. Then fasten the bow to the pins and put it in the box.

Applying rosin is a delicate job. There is also a little trick, first tighten the screws on the bow head a little, so that it is easy to wipe, wipe one side first, and wait for the surface of the horsetail to be white, and it looks like there is a layer of white powder from beginning to end when the lump is destroyed, even if it is wiped well, wipe one side and then wipe the other side.

When wiping, don't wipe long at a time, first wipe in one place, wipe out the white powder, and then extend forward to move, move 3-5 cm, loosen a little, if the force is too strong, the action is too violent, pull too long, but can not be wiped, be patient, the first time you may wish to wipe a little more, you can wipe a little less later.

1.Thick strings are inner strings. 2.Ready-to-wear inner strings. 3.The one on top. 4.In the middle of the inner and outer chords.

Summary. Hello <>

Pulling the handle down for a long time and rarely pulling it up will have a certain impact on the erhu. Long-term lowering of the handlebar position may lead to stiffness and fatigue of the finger muscles, as well as a decrease in finger dexterity and agility. At the same time, using the same finger too often to press the bass area can easily cause finger fatigue, weakness and even injury.

Moreover, playing in a low position for a long time will also increase the friction between the fingers and the strings, increase the wear of the strings, and then affect the sound quality of the erhu.

The erhu has been pulled down for a long time, and it is rarely pulled high, which has no impact on the erhu.

Pulling down the position for a long time and rarely pulling the argument and destroying the high handle will have a certain impact on the erhu. Long-term lowering of the handlebar can lead to stiffness and fatigue of the finger muscles, and will also reduce the flexibility and agility of the fingers. At the same time, using the same finger too often to press the bass area can easily cause finger fatigue, weakness and even injury.

Moreover, playing in a low position for a long time will also increase the friction between the fingers and the strings, increase the wear of the strings, and then affect the sound quality of the erhu.

In order to avoid the above problems, it is recommended to pay attention to the skills of practicing high positions and gradually increase the frequency of using high positions. In addition, hand massage, relaxation and other activities can be performed to relieve hand fatigue. At the same time, pay attention to the correct sitting and holding posture to reduce unnecessary finger movements and improve playing efficiency and accuracy.

Finally, it is necessary to pay attention to the maintenance of the erhu, replace the strings through the fingers, and maintain good string tension, so as to ensure the stability of the sound quality and prolong the life of the erhu Shouwei faction.

The erhu has been pulling the first and second positions for a long time, and the third, fourth, and fifth positions are rarely pulled, does it have an impact on the sound of the erhu?

Erhu pulled for 2,3 years.

Hello <>

Long-term only pulling. The first and second positions will have an impact on the sound of the erhu. First of all, the methods and techniques of playing the strings in different positions are different, and the skill level of the player can be improved by practicing in different positions. If for a long time only in.

When you practice in the first and second positions, the skills and feel of the other positions will be reduced, resulting in a lack of rich timbre when playing, and it is difficult to exert the expressive power that the erhu should have. Secondly, the long term is only in.

Practicing in the first and second positions will also cause the contact point between the string and the body to become single, which will limit the resonance space of the erhu, and the sound of the production bureau Chunsheng will be relatively monotonous and lack a sense of hierarchy. On the contrary, if you can practice regularly in each position, you can make full use of the entire resonance space of the erhu to make the sound fuller and fuller. Therefore, it is recommended to practice more in different positions when practicing, so as to make the best effect of the erhu.
