Many Hu friends may have discovered that the environment in which the erhu is played has changed a lot, and the timbre of the erhu will change accordingly. Why? Today, I will share with you the reasoning behind it.

A friend of Hu reported that his erhu has a problem. He used to practice well at home every day, but he went to another city to take it to pull it in the past few days, but it didn't feel right. It must have been accidentally damaged on the road. , would like to send it back to the manufacturer for inspection and repair. After the manufacturer received it, they found that there was no problem with the piano, there was no damage, and there was no problem with the sound. After careful inquiry, I found out that when the novice Hu You was playing erhu at home, he was afraid of disturbing the people. He closed the doors and windows and pulled it in the room every day. This time, he changed the place and was in a warehouse in the factory area. Practice during the day without disturbing others. In fact, there is no problem with the erhu, so the round-trip shipping is wasted.

This change in sound due to changes in the environment is due to changes in "reverberation". To put it simply, we all know that when sound propagates in the air and encounters obstacles, it will be reflected, resulting in echoes, and several reflections will cause "reverberation". The dust density and humidity in the air are different, and the space size is different, which will directly affect the frequency and speed of this reflection, and the "reverberation" time will be different. Quantitative change brings qualitative change, and sound will change.

So back to the question we said at the beginning, Hu You took his erhu from a clean, small, closed room to a huge, open warehouse in the factory area. It is easy to understand why the sound changes. So dear Hu friends, when the same erhu is changed to a completely different environment and the sound changes, don't be impatient to think that your erhu is broken, first consider whether the environment has changed too much.
