My erhu voice is a throat break, and the erhu voice is noisy

Hehe. The same is true of my family's old cheap piano.

Although the quality of the piano has a lot to do with the sound quality.

However, it is not possible to change the piano.

Some improvements can be made to the exterior of the instrument.

The sound quality can be effectively improved.

I'll tell you about my recent experience.

The first is the strings.

You have to buy something better.

But if it's not an erhu major.

It doesn't need to be too good either.

Like the Beijing silver erhu strings I use now.

You can use Dunhuang or Baihua erhu strings from Shanghai.

The second is the position of the saddle.

Part of the one mentioned in your question is the wolf sound of the erhu.

Unlike noise, note the difference here.

That's what happened to me.

I thought about solving it.

As the vibration of the strings under the saddle resonates with the above.

So there will be dissonant sounds on some notes.

The position of the saddle can be at the ** of the barrel, or it can be 4 cm from the top of the position, and you can look at it yourself.

The third is the wolf sound pad.

That is, the cushion under the saddle.

I've tried a lot of materials.

It feels best to use it now.

It is a sound clip of the rubber which I made by oneself.

It can effectively prevent the vibration from below from resonating with the above.

And the clip did not touch the snakeskin.

In this way, the sound of the erhu will be brighter, crisp and cleaner.

The specific production method is as follows:

Take a piece of rubber, cut it into about 6 x 6 x 6 cubic millimeters, cut two grooves on it, cut it to a depth of about 3 mm (that is, half of it), and snap it into the string under the saddle.

Start by allowing the strings to fully enter the slot.

Move the rubber to the lowest first.

Slowly swipe upwards.

Pull for every millimeter or two.

Let's see if there's anything that doesn't sound good.

Until the dissonant tone is completely gone.

That's it, so that the sound you pull out will be much better than the original, and finally, the problem of carrying the bow.

Beginners always like to pull the strings with a lot of force.

Although I don't know what level you are at right now.

But it's good to learn from it.

The principle of the bow hair string is to overcome the friction between the two sides.

When you exert exactly enough force on the bow to overcome the frictional force.

The tone will be at its best.

And erhu beginners always think of making the volume a little louder.

I pull the strings with a lot of force.

The usual result of this is:

The note that comes out in the first half of the bow is accompanied by a murmur, which is very unpleasant, that is, getting used to your piano.

Be good at exploring.

Just master the optimal strength.

Other than that. The angle of each erhu is different.

I'm going to have to figure this out for myself.

That's it

Hope it helps.

If there's anything you don't understand.

Welcome to the common erhu issue.

It is mainly caused by the rough production of the material, and then when you carry the bow, the bow should be perpendicular to the skin, and keep this angle, which is what we often say about the bow to go in a straight line. Go to your local professional teacher and ask him to tell you, and everything will be clear.

The python skin is not good, the bow is not good, the horse is not right, the fine-tuning or the quality of the daughter is not good.

Is your bow suitable? Rosin can't be less, and can't be more. If you are using a jack, it is recommended that you use a rope to retie it (preferably the kind used for palm shoes).

Choose a better saddle and padding tweed cloth underneath. Whether the jack is metal or rope, it is not a problem, the important thing is that the 2 heel strings are really close in the jack position. If it doesn't work, it's a problem with erhu production.

I've convinced you, are you a beginner? , you'd better buy one for 700 to 900 yuan.

Is it the wrong height of the line on the string?

Or is it the little piece of wood in the barrel that is crooked?

Look at your piano, and the bow, and the way you play it, it's all very important, and when you play the violin, keep the bow hair completely attached to the strings.

I bought the piano for 3500, and it will be difficult to listen to if it is not good to play.

The key is to work hard.

1. If the strings are not corroded, they do not have to be replaced, that is, they must be replaced with a set, and if they are replaced, the timbre will be affected.

2. If the bow tail has not been eaten by insects and is still straight and neat, it does not need to be replaced, clean up the dust, the rosin quality should be good, and the dosage should be moderate. It's okay to change the old bow if it's not pleasing to the eye, but it's not directly related to the timbre.

3. Wipe the python skin with a soft cloth, if it feels too dry, you can wipe the chicken fat appropriately, not excessively.

4. The saddle is slightly ground on the fine sandpaper with a glass plate to make it smooth.

5. To rearrange the jacks, it is best to use 200-300 wool yarn, evenly wound 6-10 times, and the width of 8-10 mm is appropriate.

6. If it is not a machine shaft, please wind one string in reverse to separate the two strings.

7. Put a small piece of sponge (foam) between the strings at the lower end of the piano saddle and the python skin, and the position can be adjusted up and down.

If there is still noise, then you have to pull hard, and it will be fine after a while. By the way, see if the python skin is glued? Uneven growth also has an impact.

It might be better to change the string and change the bow.

The erhu is carefully disturbed by the bow to cause the bow hairs to rub against the strings, causing the strings to vibrate and make sounds.

The principle of erhu pronunciation is that the steel strings vibrate, which is transmitted to the top of the piano saddle, and then vibrates the snakeskin sound, the snakeskin is tight, and the snakeskin is the source of the sound. The quality of the sound is also determined by the thickness of the snakeskin and the frequency of the vibrations.

The basic structure of the erhu:

Barrel. The barrel is an important part of the erhu, which vibrates the resonant body of the leather pronunciation after rubbing the strings through the push and pull movement of the bow. The texture and shape of the barrel have a direct impact on volume and sound quality.

It is generally made of rosewood or mahogany. The shapes are hexagonal, octagonal, circular, front octagonal and rear round, etc., and the commonly used is hexagonal.

There is a sound window inlaid behind the barrel (usually a carved wood window), which not only plays a decorative role in the barrel, but also has certain benefits for pronunciation, transmission and sound filtration. The barrel is the resonating cylinder of the erhu, generally made of ebony, mahogany (there is very little rosewood), and the cherry tree is also made of rosewood or bamboo, and in the seventies began to make the low foam (ABS) material horizontally formed.

Its shape is mainly hexagonal, 13 cm long, with a diameter of 88 cm on the opposite side of the eye, and in some areas it is made into a round or eight-ridged square. The waist of the cylinder is slightly thin, and the rear mouth of the cylinder is open or the device has a sound window with various styles of flower holes. The barrel plays the role of amplifying and rendering the vibrations of the strings.
