Folk music is developing with each passing day, and the erhu instrument has also developed very greatly. No matter from the repertoire, teaching, performance and production, the erhu is more and more loved by more and more people. For learners, enthusiasts, who want to buy a good Erhu in all aspects, how happy it will be.

Now there are more ways to buy erhu. You can buy it at a piano store, online, or even directly from the manufacturer. Let me talk about a little experience and experience of buying a piano in a piano store.

After watching the process of buying a piano, basically you have to audition for a while. Some piano shops may have larger areas, while others may have smaller storefronts, and the instruments and other items on display are not the same. But buying a piano basically requires an audition. The audition environment has a very important influence on the choice of piano.

I remember that many years ago, when I was a student, I went to a piano shop to buy a mid-range erhu. On the premise that everything was good, I started to audition in the piano shop. I felt that the sound was still louder, although the new piano was still There is no open tone, but the sound quality of the first and second positions feels okay. There is still a bit of brightness on the sound. But after I got home, I played this piano again, and the sound felt much smaller, and it didn't feel as thick as when I played it in the piano shop. In fact, the problem lies in the environment during the audition. We all know that when sound is heard by the human ear, it is not directly heard. It is a physical process in which sound is heard in the air, and sound waves are heard through reflection and delay. (More or less decoration will cause different changes in the standing wave of the sound, which has a great impact on listening.) The situation I mentioned above was an audition in a slightly larger piano shop, and the placement of the items was also different. Not much. In this way, during the audition, the reflection will be less obstructed, and the time delay will also change. The sound seems to be louder and louder, as if there is a bit of reverberation. This is the Erhu flavor with ambient MSG added. When playing at home, most of the decorations are still in the bedroom, and the time for the sound of the piano to reflect to the ear is short. In fact, the erhu has not changed, but in this situation at home, the environmental MSG has weakened in the piano shop. In terms of hearing, there must be a lot of changes in sound. However, in such an environment, it can make people more conducive to hearing the state of the new erhu's own voice. For a piano with a low sound and a dull sound, it is possible to artificially make it sound louder or smaller due to the different influences of the environment during the audition.

Now, there will be a video audition on the page that sells erhu online. Although they will explain to the viewers that they will not use methods such as microphone reverberation to deliberately beautify the violin to be sold, but we are watching the environment of the audition. , it can be seen that many of the videos were recorded in a more open environment. Well, for such a video, I personally think that there will still be some discrepancies between it and the original sound of the piano. This needs to be carefully distinguished by the experience of the buyer.

In the following years, it was a common thing to choose erhu for others. After paying attention to the necessary aspects such as wood, leather, weight, etc., I paid great attention to the environment during the audition. After pulling the chair for a while, I often move the chair to a place slightly closer to a wall, and switch several piano wheels of the same price to compare the environment and sound. At this time, let the piano tube face the side of the wall, or pull it in a corner. This has a better effect on the sound reaching the ear quickly. Thereby reducing the process of sound waves in space and a longer response delay. It can better distinguish the sound quality and loudness of an erhu in the new state of the piano.

Now the price of erhu is getting higher and higher. If you want to buy a good piano, you can't talk about the money, and there are also various kinds of wood skins and pianos with different prices for us to choose. A piano costing tens of thousands of yuan will naturally be more guaranteed than the quality of popular pianos. But the erhu is a musical instrument, it is to make sound. The high price can only be an important reference for a good piano, but it is not absolute. There are many unpredictable things in the production of the erhu musical instrument. The tightness of the skin, and even the amount of glue used for a piece of wood, etc., make this hand-made musical instrument have too many unknowns. What the sound is like after the sound is turned on, it cannot be quantified in advance. And it is impossible to have two erhus with the same sound. In the case of about the same, or if you want to buy a piano of the same price, when choosing a piano, in addition to those important knowledge points, you should try your best to have a better concentrated performance on a piano. I think the more important thing is to test it on the spot. Play and audition environments. In the audition of one or several new pianos, through the ear-to-sound sound quality, and the sound changes in different positions, to feel its overall sense, and to be able to look forward to the external sense of the piano, and The sound of the audition has a comprehensive judgment on the future of a piano.

People say that the sound of a good piano is played slowly, so when we choose a piano, the environment is a very important factor in the first audition. That's where we first made friends with it. It is very important to be able to become good friends in the future. We can't have too many auditory errors in the sound identification of a new piano due to the influence of the audition environment, especially for those who have not experienced enough piano selection experience. Environmental factors should also be considered when auditioning. . To find out, in the audition, the impact of ambient MSG on the sound to what extent. Listen carefully to the true state of this violin.
