Why should the piano be tuned? I think whether you are a professional or a non-professional, you will quickly answer this question, "It's because the melody is inaccurate and out of standard pitch." But if anyone wants to ask, how should your piano be tuned and how often?
I think this answer will be "brilliant", and even experts will have different opinions. Some experts will say that once a year is enough; Some experts will say at least twice a year; Some experts will say that it should be adjusted at least every three months, and so on. Which statement is correct? In fact, these answers are all right. Some friends want to ask, if they are right, who should I tune my piano according to? Here I'll tell you how to do it.
Whether or not a piano needs tuning and how often it is tuned are actually influenced by many factors.
1. The first is the intrinsic quality of the piano itself. When it comes to the quality of Qin, we can't help but talk about the brand of Qin. Generally speaking, if a piano with a better brand is advanced in technology and exquisite in craftsmanship, especially if the materials are strictly in line with international standards, the stability of the piano it produces will be relatively better. If it is a piano with a miscellaneous brand, the stability will definitely be worse, and it will be tuned frequently.
2. The internal stress of all kinds of materials used in the newly produced piano is relatively large (here mainly refers to the piano body, strings and steel plates, which are artificially aged and naturally aged in the production process). With the passage of time, the internal stress of piano parts will be released slowly, which makes the stability of the piano more and more stable, which is why the piano with a long history is always more stable than the new one.
3. Percussion music in the process of playing the piano, the strings should be struck repeatedly, and the impact of external force on the strings and the internal stress of the material itself will naturally increase the trend of pitch change. If the player is a piano player or a student in a conservatory of music, he will play much better than a beginner, then the same piano in their hands will strengthen the trend of pitch change and will soon fail to reach the standard pitch.
4. If the piano is transported for a long time or moved frequently, it will also cause the change of pitch. After the above analysis, you will know how often the piano should be tuned. Here are some personal experiences for your reference. Generally speaking, the new piano for family use should be tuned twice a year, and the more stable piano can be tuned once a year. If the piano player is a high-level student, considering the high requirements and the changes of the piano itself, the number of adjustments can be appropriately increased (subject to the player's feelings). The piano in the Conservatory of Music is tuned once every one to two weeks.
In addition, we should pay attention to a misunderstanding here. Some pianos are not tuned on time because of their low performance utilization rate for various reasons. What's more, they will greatly shorten the service life of the piano without maintenance and necessary adjustments in various aspects after being placed for several years. When the piano is left idle for a long time, the tension of its strings will be gradually released during storage, the pitch will become lower and the strings will be in a relaxed state for a long time. Once you want to play it one day, the standard pitch will be adjusted and the strings will break without adapting to this sudden increase in tension. Therefore, experienced tuning lawyers usually take the overall treatment of lowering the semitone in this case, which will have a great negative effect on the player's hearing, so the piano that has not been used for a long time should also be tuned on time.
