Erhu produces noise, often because the vibration of the strings is unstable and the barrel is not harmonious during the resonance process. The uneven structure of erhu wood, rusted strings, and disordered bow movement may cause the erhu strings to vibrate unstable. Many people have been playing the erhu for a long time and they cannot completely eliminate the noise, which is very distressing. Today, I will analyze with you how to reduce or even eliminate noise.

Generally speaking, it is normal for rough and inferior erhu to produce noise, such as the wood structure is too sparse, the piano skin is too thin, etc. When pulling, the string is not pressed firmly, the strength is not enough, or the bow is not stable, the strength is too large or too small, and the speed is uneven or too slow, all of which will produce noise.

So, if you want the erhu to have no noise, objectively speaking, you must first buy a decent erhu through erhu direct sales, not to mention high-end erhu. The body is complete, free of nicks and cracks. With the hardware factor, the next is the subjective factor. For beginners, the first is the basic skills of the empty string, to ensure the smoothness of the bow, the strength and speed of the bow, and on this basis, add the left hand, and adjust the strength according to the sound when pressing the string. If it is too small, there will be noise. If your hand hurts, you can gradually adjust the intensity from small to large, adjust to the limit of full sound, and remember this intensity through repeated practice.

In addition, if the air is too dry, noise may also be generated. At this time, it is necessary to use appropriate methods to increase the ambient humidity to the erhu. Solve these problems, and your erhu can eliminate noise.
