A good piano has four criteria:
1) Durability: This indicator is the most difficult to judge, even for senior piano technicians. Because there are some invisible quality problems in the materials used for piano. I can't react at the moment. Our suggestion is to buy famous brands. Because the history of famous brands proves its reliable quality. There are also different grades of famous brands. High, middle and low-grade pianos have famous brands, which can be chosen according to their own needs and economic ability.
2) Sound quality: Sound quality is the most important and difficult indicator of musical instruments. Some violins cost several hundred yuan, while others cost several million yuan, mainly because of the different sound quality. It is difficult to judge the sound quality because it is so abstract that most people have no confidence in it and are easily misled by others. In fact, everyone has different feelings about the beauty of sound quality. Some people like soft sounds, others like bright sounds, which seems difficult to grasp. In fact, as long as you have confidence, your own comparison is the most reliable. If you can't play the violin, you won't listen at all. As long as you play one key at a time with the same strength, it is easy to hear the difference. You can find the piano that you think sounds good in the appraisal. But one principle remains unchanged: a loud piano is not necessarily a good piano, but a good piano must be loud. It must not be a good piano with a low volume. Some people will say that the noise is loud, which is completely misleading.
3) Whether it is good to play: Good playing refers to the reaction ability of the keys and the weight of the keys, which is unanimously recognized by everyone. Different people have different requirements for the weight of keys. Piano teachers in China tend to prefer heavier keys. The United States generally requires fewer keys. The key is that it is too light to control, and it is easy to get tired if it is too heavy, so it is better to be moderate. If you are worried that the person who helped you choose the piano will be misled, you might as well find a child who can play the piano to help.
4) Style modeling: The appearance modeling of the piano is very important, which can reflect the decorative style of the piano. However, after all, it is only a decorative function and cannot be neglected. Because the piano is not furniture after all, even furniture has its main functions.
