Some friends will have noises in the process of playing the guzheng, and there are many reasons for this. The following is to answer the different reasons for everyone.

1. After plucking the strings, the resonance of the strings on the left side of the bridge will also produce noise. At this time, the position of the bridge should be adjusted in time and the tension of the strings should be adjusted to eliminate the source of resonance and the noise.

2. After the string is plucked, the resonance of the string section on the left side of the bridge will also produce noise. At this time, the position of the bridge should be adjusted in time and the tension of the strings should be adjusted to eliminate the source of resonance and the noise.

3. It may be that there are irregular cracks or splits in the prosthetic armour worn by the performer, and a hoarse sound will be produced when touching the strings with such armour. Then, it can be smoothed with gauze, trimmed with scissors, or put on a new prosthesis in time.

4. There may be a problem with the angle of the bridge supporting the strings. At this time, gently adjust the piano code: move it up and down or twist it left and right, and try playing the strings in different positions to avoid hoarse noise.

5. The small groove of the small bone piece on the bridge is too tight, the strings are stuck in it, and it is easy to make noise. Correcting or widening the small groove with gauze in time can avoid the appearance of noise.

6. When the contact between Yueshan and the strings at the tail of the zheng is in the state of chronic string contact, noise will also appear. There are two ways: first, lower the parts where the strings are fastened by the pegs, relax the strings, and then restore the strings to their original positions, which can increase the pressure of the strings on Yueshan and avoid the appearance of noise; Put a small piece of soft cotton or something like cotton where the strings touch to reduce the vibration of the strings and also reduce noise.

7. If the four feet of the piano touching the zither stand or the piano table are not stable, there will be noise due to shaking. The feet should be flattened with cloth or fixed with screws, and try to keep the four feet on a flat surface to avoid noise.

8. If the four feet of the piano bench or table touching the ground are not on the same plane, there will be noise. In this case, the bottom of the zither stand or table should be leveled. In order to avoid it in time, you can first use the foot on the beam at the lower end of the kite frame to relieve excessive shaking.
