In fact, except for the kind of very talented people, the frequency band of the sound that the average human ear can recognize is limited. In terms of recognizing the sound of the erhu, most people can distinguish the more obvious noises, while the slightly subtler noises may not be able to be heard. But professional erhu players can always hear erhu noises that ordinary people cannot. Why is this? You may say: That's natural, professional erhu players who have been listening to it for decades and have experience can definitely hear it. However, many old Hu friends who have been playing erhu for decades do not actually have the ability to recognize subtle noises. professional Erhu teacher. This is a very interesting phenomenon, and it fully shows that the ability to discern must be strong without listening too much.

First of all, let me tell you an interesting story: there is a man who is a taxi driver with nearly 20 years of driving experience. He has been in various car forums and ticket circles for a long time, and has personally driven hundreds of cars. The performance and the driving experience are well known, and just a couple of laps can pick out the slightest flaws in a car's performance. However, some time ago, when he experienced a multi-million-level sports car, in his own words: it was like heaven! From then on, he felt that those hundreds of thousands or even tens of thousands of cars were full of problems... So, how can those old Hu friends who have been driving for decades but stay in low-end erhu sound quality experience true purity The sound quality, so as to contrast the subtle noise?

Just like there are several footprints on the snowy ground, those footprints will be particularly conspicuous. Erhu is actually the same. Professional erhu players are immersed in the clean and beautiful sound for a long time. The world in their ears is like the vast white snow. What kind of erhu only has a slight noise, it is as obvious as leaving footprints. As for those Hu friends who have been playing erhu for decades but do not have the ability to recognize subtle noises, the snow in their ears is already full of footprints, and even more footprints are still the same.
