Everyone who learns the qin has a heart to love the qin, and often regards the qin as a life and loves it. Therefore, winter is the most hated season for piano players. The weather is cold and the air is dry at this time. If the air conditioner and heating are turned on for heating, the piano may crack and deform; if it is not turned on, the fingers will be cold and stiff, and the lower fingers will not be smooth. It was unbearable for a while, I turned on the air conditioner or heating, and after practicing the piano for a while, I suddenly found that there were cracks on the piano, the mountain was cracked, the surface of the piano was bulging, and there was a sand sound... Then I began to feel very distressed, sleep and sleep. It's uneasy, I can't sleep well if I don't practice the piano, all of this is understandable.

Generally, there are three main reasons for the cracking of the guqin panel:

The first is because of the dry climate. When the ambient humidity is less than 40%, the panel will begin to shrink and crack at its stress weak point. Therefore, the indoor humidity must be kept above 40%. If you don't know the indoor humidity, go ahead and buy a hygrometer.

Secondly, it may be that the guqin panel itself has internal damage. When you first purchased it, you could not see it, but when the ambient humidity changes greatly, it will appear.

In the end, when the guqin is made, the panel processing is not in place, so when the panel is topped, the prestress is too large and the problem of cracking occurs.

Now that the reasons for the cracking of the guqin have been known, in response to these problems, piano friends must pay attention. If the buyer does not have the ability to discriminate in this regard, it is recommended that you choose a famous piano with better after-sales service.

Having said so much, I just want to tell you all: For Guqin, cracks and slight cracks on the surface of the piano are normal phenomena, and it is necessary to treat this problem with a correct attitude.
