How to tell if the piano is caused by resonance and caused by metallic sounds

The piano is composed of more than 8,000 parts, 20% of which are made of steel, iron, aluminum alloy, synthetic materials, tweed, felt, 80% are made of wood, each string bearing is subjected to a tension of 75 kilograms, an upright piano is composed of 221 pins placed in wood, and the total tension of a string bearing of a grand piano can reach about 20 tons. The temperature and humidity change throughout the year, so take good care of your piano.

First and foremost, it is important to pay attention to the following:

1. Pest prevention: Because a large number of pure felt, woolen and other wool products are used inside the piano, which is easy to breed fungi and insects, insect repellent should be placed inside the piano regularly, especially in the humid season (the general living room is well ventilated, such as the bedroom can also be well ventilated).

2. Anti-drying: The northern region is very dry, and the relative humidity of the piano should be kept between 40%-60%. Especially in the heating period in winter, it is necessary to place a water cup in the piano to adjust the humidity inside the piano and prevent the keyboard from being twisted and deformed, causing the keys to not fall, the loose pins and nails leading to pitch change, and the soundboard from cracking.

The method is to open the lower door panel of the piano, place a large open water cup, and add water regularly in the bottom gap. The piano should be kept at least one meter away from the radiator.

3. Prevent direct sunlight: long-term direct sunlight can make the piano paint discolored, cracked, and lose its luster, so a curtain should be used to cover or cover the piano cover. (Depending on which of your bedroom or living room gets longer direct sunlight, be selective).

4. Noise: Because the piano has a very wide range, if the vibration frequency of the items placed near the piano is consistent with the vibration frequency of a certain tone of the piano, when this sound is played, it will produce noise due to the principle of resonance, please pay attention to eliminate it in time. (Look at the size of the bedroom, if it is too small, the piano is too close to the surrounding objects; The living room should be placed in a good place, preferably wide, with few objects around).

Floor: The floor is too soft to withstand such a heavy piano and deform, and when the piano is played, these objects are in tune with a certain rhythm of the piano, resulting in the aforementioned noise due to the action of resonance (distinguishing the bedroom from the living room floor).

5. Move lightly and move less: When transporting and placing the piano, it should be handled with care, and after the position is fixed, move as little as possible to reduce unnecessary vibration that affects the rhythm or damages the parts.

Secondly: the piano position can be based on personal preference, if it is an upright piano, there is not much difference between the bedroom and the living room, if it is a grand piano, it is best to put it in the living room, the general living room is larger, and the vocal range is better than the bedroom.

Thirdly, it is necessary to pay attention to the echo of the living room and bedroom, which will directly affect the sound quality of the piano.

Also, pay attention to the dry humidity of the living room and bedroom, keep the dry humidity inside the piano, 40%-60% is the best, if you are a southern city is more humid and good, if it is the north, this should be calculated according to the square meter of the humidifier, if enough for the living room, then the guest bedroom is fine.

In short, the piano placement is necessary, it is a very delicate thing, the room temperature is too high and too low, too dry or too humid are not good for the piano parts and body. Also remember that you need to adjust and mechanically finish 1-2 times a year to maintain optimal use.

No, it won't

This murmur is not a resonance between the sound of the piano and the objects in the room, but from the piano itself.

This murmur may come from the clear resonance inside and outside the piano. If there is a murmur in a specific pitch, it may be that the heavy objects placed on the piano affect the sound of the piano. Alternatively, it is possible that the inside of the piano has entered the debris.

Similarly, it may be that there is a problem with the parts of the piano, you can open the front cover and check the damper. Especially in places with a lot of noise, the damper may be displaced, and it may not fit the strings completely, so the damper will be delayed or unstable, so it will produce a sizzling noise.

It is also possible that the piano is not in tune. The keys of a piano usually correspond to 2-3 strings, so if the strings are inaccurate or the intonation is defective, it will make a sizzling sound. In this case, you can only find a lawyer to adjust, and there is no problem if you usually pay attention to inspection and maintenance.

Resonance is now open to the letter.

Sometimes it happens inside the piano, but most of the time it resonates because the sound of the piano resonates with the outside. Items that resonate easily include boxes, lighting fixtures, lampshades, and walls around the piano.

To place an electric piano.

placed close to the wall).

So, you can move around the piano while playing the resonant keys.

Items that resonate, or press and hold your hand to confirm.

In addition, the loosening of the screws inside the product can also cause resonance, so if necessary, contact the local repair station for treatment.

Right! It is that the piano is not tuned well, the strings are loose, or the small pillars connecting the strings are loose, it is recommended that you find a professional tuner, or will you ask if your piano is bad

Hehe, I didn't tune it by ear at the beginning, but I said that the metal sound he didn't admit it, said he couldn't hear it, and then he used the instrument to test me, saying that you see the sound is accurate, I have no problem tuning, I asked him why there is a metal sound, and the strings tremble very much, he replied that he couldn't explain it, you said I was depressed, I was most worried about whether he had tuned my piano badly, I wanted him to come and retune it for me, he said it could be tuned, but after tuning, the tone was not accurate, don't let me blame him, what do you say I should do to answer:

If the tone is accurate, then don't tune it, that is, there is a gap between the small pillar in your piano and the soundproof board, so when you play the piano, it will be a sound of flowers, which is the metal sound you said, it is recommended that you go to the one that sells the piano, let them repair it for you, after all, Yamaha is a very good brand in the piano, generally Yamaha and kawai's piano does not need to be tuned within five years, and the quality is absolutely ***, so it is recommended that you go to the one that sells the piano, ask well, let him return it if it is really not good, and the general piano store is a follow-up question:

**C's do and small word 2 groups of mi together will be more serious when pressed, listen to it alone, if it's a problem with the piano, then there was no tuning before, there was no problem, the sound is very good, since the tuning has been there a metal sound answer:

No, there is only the small word 2 groups of mi and **c do when the metal sound is very serious, and the strings are also very serious, and there is no such situation when they are respectively with others, answer:

Metallic sounds generally exist in northern areas, because the humidity is relatively small, the hammer will be harder, and there will be metallic sounds when knocked out. It is also possible that after a long time, some parts rust and produce associated sounds, which I think can only be improved but not removed.

Not necessarily, it depends.

Some brands of pianos have a slight metallic sound when playing very low notes, which sounds very textured, but some people don't like it. Either way, the metallic sound is much smaller than the music itself.

If you're hearing almost exclusively metallic sounds, there's definitely a problem. Or if you hear a very unpleasant metallic sound, there may be a problem. However, it is difficult to say whether it is tuned badly, and under normal circumstances, the tuner will not tune the piano into a metallic sound.

To sum up, your situation needs to be judged by listening, and asking here will not yield results.

The small pillar that connects the strings is called the pinshaft, the new piano will not be loose, the quality of the piano with ten years and ten years rarely appear that the string is loose to the sound of the situation, to say that the sound is basically the old piano, in addition to I don't know whether these answers are written or copied from elsewhere or written by themselves, but first: to say that the strings vibrate particularly strongly, how to make a sound if the strings do not vibrate? All stringed instruments are characterized by the thicker the string, the greater the vibration and the lower the frequency.

Second: the piano has a metallic sound, and some cheap pianos will have a metallic sound, and various reasons are generally caused by the resonance of the strings. All kinds of factors, the responsibility for the production of metal sound when tuning is a bit difficult to push to the tuning lawyer, no professional knowledge, don't shirk the responsibility to others, the tuning lawyer is only responsible for you to tune the pitch, during the piano problems The tuning lawyer does not have the obligation to give you responsibility, just like the problem checked out during the maintenance of your car seems to be the repairman who broke it for you, and the repairman wants to compensate you to the first reason, in addition, the sound checked by the instrument is accurate, which proves that the tuning lawyer's skills are very good, If you can't answer, it may be that you are not very good at communicating, and thirdly, there is the piano that said Yamaha and kawaii***.

I don't need to tune the piano for three or five years, this sentence can only prove that I don't know the piano, the piano is idle and not in a state at least once a year, and I don't want to tune it once every two years is also the most basic, and the piano in use is light for one or two hours a day twice a year. I use a lot of tunes three or four times a year, and the piano used during the concert performance is used at any time, let me give you another example: who doesn't maintain their car for three or five years?

It is the responsibility of the manufacturer to drive without maintenance for a lifetime? Something wrong with the brain! That sentence can only prove that he understands the concept that the piano can be played without tuning, when it can't be played is broken, it is time to need tuning, it's really funny, and Yamaha's piano sold in China is a specific model only sold in China, and the Japanese model is not sold in China, kawaii's piano is made in Yichang, the domestic piano OEM kawayi, the Japanese kawayi does not provide any material technology, just earn Chinese trademark royalties, so, wake up,

The greater the amplitude of the vibration of the <> string, the louder the sound. The piano is a keyboard instrument in Western classics, and is known as the king of musical instruments. It is composed of 88 keys (52 white keys, 36 black keys) and metal strings.

The Italian Barto Romeo Christopelli (1655-1731) invented the piano in 1709. The range of the 88-key piano ranges from A0 ( to C8 (, and 108 keys is up to B8 (. The piano is commonly used for solo, ensemble, accompaniment, and other performances.

Because the amplitude determines the loudness of the sound, the greater the amplitude of the vibration of the string, the louder the sound;

The frequency determines the pitch of the sound, so when you hit different keys, you will hear different tones of sound, because the strings vibrate at different frequencies

So the answer is: loudness; Frequency

a. The volume adjustment button will change the intensity of the sound, and the purpose is to change the loudness of the sound, so A is wrong;

b. The sound of the piano is produced by the vibration of the strings, so B is correct;

c. The "soprano" sings in a higher pitch than the "tenor", so C is wrong;

d. Sound is propagated in the form of sound waves in the air, so D is wrong so choose B
