That is, everyone should not be too subjective or too stubborn. Often if you don't like something, it's because you lack cultivation in it. Just like Beijing Opera, young people generally don't like it, but if you delve into it, you may become an enthusiast. The same is true for the sound of a violin. As long as the sound is the sound of a violin, then the sound of every violin is reasonable, has its own reason, and has its value. People and the violin influence each other, and they have to have a relationship with the violin. As time goes by, you will feel that this is the sound you like, rather than the illusion of the sound of the violin when you can't play the violin. You have to believe that by playing one note after another, the sound of the violin will get closer to the voice in your heart, and the wooden sound of the violin itself will also change the voice of your heart. The human piano interacts with each other, and finally your piano will produce your own unique sound. Of course, this should be based on the fact that the sound is basically fine, otherwise your ears will be damaged. Finally, let’s talk about violin debugging. You should have your piano tuned by a tuner every year. Tell the tuner what you don't like about your instrument. As the saying goes: "Good pianos are all made by tuning." I feel that every time I play the piano for a year and tune it again, the quality of the piano seems to have improved. If there are no conditions, you should gradually learn to change the sound columns and trim the bridge.
