When we want to learn a musical instrument, we all buy one for ourselves, so what's the problem with buying it back? Here are some common problems with the new guzheng you bought.

If it is found that the code of a certain string has the sound of the bottom of the column hitting the surface after playing hard, it is commonly known as "jumping code", which means that the tension of the string is not enough or the effective string length is too short, or the height of the code is not enough. First check whether the numbers are arranged according to the number. If there is no problem with the arrangement, you can move the code a little to the left and then tighten the strings.

If you find that a certain string has a sandy sound, commonly known as "wolf sound", it may be that the gap of the toothbone at the upper end of the piano column clamps the string and affects the vibration. It can be avoided as long as the two sides of the gap are enlarged with a triangular file.

If you find that a certain string does not sound or emits a sandy sound, twist the nylon on the outside of the string with your hand. If the twist moves, it means that the nylon is not tightly wound and hinders the vibration of the string. The string is defective and must be replaced.

If it is found that the zither body is uneven, check whether the ground on which the zither stand is placed is flat, and try to level the guzheng stand. The guzheng can be laid flat by nailing a piece of rubber of the same thickness where there is a gap between the guzheng body and the combination frame.

If there is a buzzing sound at the head of the guzheng when the strings are plucked, please check whether the lid of the guzheng head is closed tightly. Whether the items in the piano box are uneven or touching the piano nails in the box, and do not put too many things in the zither box, if there are too many or uneven things, it will cause the items in the box when playing the piano. resonance, resulting in noise.
