How to tell the difference between a good and bad piano? How do you measure the quality of a piano?

1. A good piano should be: elegant, stable and harmonious, the sound can sensitively express different strong and weak sounds, the timbre is uniform and uniform in the whole range, and the piano can be played without noise and dumbness.

2. A good piano should pay attention to when playing, soft and beautiful, strong and bright without "thief", after playing the keys, its depth is within the range of millimeters, and the touch sensitivity when playing is appropriate.

3. A good piano, the keys are flat, the gap is even, the pedal is sensitive, the feet and hinges are noted.

There is no problem with the lock, and the soundboard behind the piano is not cracked.

If you want to distinguish the quality of the piano, you can judge it from your intuitive feelings. To put it simply, it is to feel the texture experience of playing, and this experience is divided into two aspects, that is, timbre and feel. This is because all the mechanical structure of the piano is optimized for these two ultimate goals.

Therefore, a good piano tone is not only mellow and not stuffy, because the tone is mellow to a certain extent, it will be dull, and loud to a certain extent, it will be fried; It is difficult for a bad piano to take into account this seemingly contradictory attribute, either it is dull and not loud, or it is not mellow at all, and it is a combination of very deep and complex technology and art to reconcile these two contradictions.

The second is the contradictory attribute of a good piano feeling that is soft but not sticky, sensitive but not brittle, because the soft feel will be sticky to a certain extent, and sensitive to a certain extent, it will feel crispy and lose that heaviness; It is difficult for a bad piano to take into account this seemingly contradictory attribute, either it feels soft and sticky and not sensitive enough, or it is quick to respond but loses its soft and heavy texture.

In addition to this, you can also judge by the evenness and smoothness of the experience. Because the piano contains 88 keys, the overall performance of a good piano is uniform and smooth, while the poor piano may have a good timbre performance of the keys, and some have acceptable hand performance, and various differences are obvious.

Judging the advantages and disadvantages of the piano can start from these aspects:

1) Sturdy and durable: The quality of the piano is not reflected in a short time, so my personal recommendation is to buy a famous brand. Moreover, there are different grades of famous brand pianos, high, medium and low grade pianos have famous brands, which can be selected according to their own needs and economic ability.

2) The sound quality is good or bad. For the sound quality of this is also a more professional judgment, in fact, the beauty of sound quality also varies from person to person, in the identification of a principle is unchanged: a big volume is not necessarily a good piano, but a good piano must have a large volume.

3) Whether it is easy to play. The responsiveness and sensitivity of the keyboard is a criterion for judging the quality of the piano, and different people have different requirements for the severity of the keys. The key is too light to control, and the key is too heavy to fatigue, so it should be moderate.

4) Style modeling. After all, the appearance of the piano is just decoration, but a good piano has its own style in terms of appearance and style, which you can find through comparison.

Sound quality: Sound quality refers to the color of the piano sound, including: the purity of the sound, the texture of the sound, the sensitivity of the sound, etc.; Reed.

Haptics: Tactile refers to the player's perception of the mechanical movement performance of the piano, including the reaction speed of the machinery, the weight of the dropped keys, the depth of the dropped keys, etc.;

Workmanship: refers to the overall manufacturing level of the piano, including the appearance of the piano, the quality of the lead orange paint, the accuracy of the machinery, etc.;

Stability and durability: each piano needs to be adjusted regularly, and one of the reasons for the piano to go out of tune is the huge tension (about 20 tons) that the strings are with, so the post-installation structure of the piano should be carefully designed to improve the efficiency of anti-strain and extend the adjustment interval; It is recommended that you go to Baitong Piano Store to experience it for yourself, and Baitong Piano Co., Ltd. has a variety of domestic or imported pianos, so that you can feel more of the difference between each piano before.

1.To listen, the articulation of the strings in the upper register must be crisp and bright, and the brighter the better, without mechanical noise or the sound of hitting wood. In this way, the high register is penetrating when played with the low register.

When playing in the 3 registers at the same time, the pronunciation of the low range is not stiff, and it is better to have a soft and thick feeling. As for the midrange, it feels clear, rigid and soft. In addition to inspecting the 3 pitches of the high, medium and low tones, when buying the piano, you should also open the top of the action to the sky wood cover and the door, to see the junction of the copper winding string and the bare steel string, when the upper and lower adjacent to five or six keys play continuously, there are no obvious traces of timbre, some are poor, no is good.

Check the 3 pedals of the auspicious pin, whether there is noise in the movement, how sensitive it is, and whether the performance is good, that is, when the right pedal is pressed, the sound of the performance will be extended; Let go of the foot, and all the sounds quickly stop the wheel limbs. The right pedal is used the most and should be double-checked. The pedal on the left is a weak tone, if the volume is significantly reduced when you press it, it is good, and if you press it, you need to adjust it.

The middle pedal is a soft-tone soft pedal.

Check the strings and open the upper and lower doors. The first thing to see is whether there is an obvious difference in the color of the bare steel string, and the steel string is better with the same color of the same manufacturer. The second is to observe whether the color of the copper wire of nearly 30 winding strings is unified, and whether the size of the bare steel strings from the upper string pillow is uniform.

Then go down the door to observe whether the first "horse nail" at the top of all the strings is uniform in size. There is a length or unevenness, indicating that there is a problem in the process during the winding operation.

4.Kan soundboard: that is, the soundboard, which is the main part that determines the timbre and resonance.

The wood grain (growth rings) of the soundboard is uniform, in the range, no more than 3mm, and it is thin and straight, without knots and no cracks, in addition, the gaps of the composition should be thin and straight, and the glue is not exposed on the plane of the soundboard. Generally, only one layer of alcohol and shellac is used on the soundboard to dissolve the "wine paint", and the thick paint will affect the resonance.

5.Check the action, open the door, and carefully observe whether the mechanical parts of each key button are evenly arranged. That is, to see whether the climbing wire is symmetrical before and after; what is the space between the felt mallets; If there is a part of the tweed, it means that the instrument has been used for a period of time.

Then observe whether the color of the felt mallet is uniform.

6.Piano shell: The paint should be as bright and flat as possible. In fact, the most important thing for a person who actually plays the piano is to listen to the timbre. However, users of strange colors and strange designs should be careful, as unconventional colors can easily cover up the defects of wood materials.

You just smiled silently at me, and I found that you were the most beautiful at this time.

Because your smiling eyes are full of praise and affirmation for me, and engraved with friendship and support for me.

You smile but remain silent, which proves that you truly appreciate me, identify with me, and love me.

You laughed and shouted at me your admiration and praise, and I felt a little frightened.

Because I can feel that there is too much exaggeration and hypocrisy in your laughter, in your loud voice.

At this time, I have to spend some time thinking about it, laughing and loud at you, and seriously speculating about ......

Judging the quality of a piano Start with these 8 details 1. There are two types of pianos from the outside: platform type (triangle) and vertical type, and the model of the piano is mostly named after the length of the string. The longer the strings, the richer the resonance and the longer the duration of the sound. The strings of the desktop type are longer than the vertical type, and the ** will be played often using the platform type (three...).
