The common sense of guzheng string maintenance in Guzheng maintenance is sorted out here for your reference, whether you are using the big-name Guzheng Dunhuang, Dingyun, Hongsheng, Dongyun, Longfeng, etc., or other brands are applicable.

1. Poor sound quality caused by poor quality of strings

1. The tone of the two adjacent strings of the bad strings is good;

2. The surface of the strings is uneven, or there is obvious looseness on the nylon wire;

3. Both the bridge resting point and the Yamaguchi string resting point are "solid", and the matching panel at the bottom of the bridge is not loose.

4. The vibration of the strings is abnormal and the sound is abnormal;

5. The hand feel is obviously loose or tight;

6. The corresponding number of the string is wrong when installing the string.

2. What is the consumable area of the strings

Strings have a wear zone, which is related to the strength and method of playing. Generally speaking, the 1st to 8th strings are the consumable strings, the 9th to 16th strings are the general consumption strings, and the 17th to 21st strings are the wear-resistant strings. If you have a new piano and new strings, it is recommended (within one year) that 1-3 strings should be equipped with 5 strings each, 4-8 strings should be equipped with 3 strings each, 9-12 strings should be equipped with 2 strings each, 13-16 strings should be equipped with 1 string each, and 17 strings should be equipped with 2 strings each. ~21 strings are not worth buying for now.

3. Whether the strings are broken before replacing them with new ones

Beginners of guzheng often don't change the strings until the strings are broken, and some beginners think that even the strings in the high-pitched parts can last for several years because of their low playing strength. In fact, like other strings, guzheng strings have a period of optimal sound quality. After this period, due to the increasing fatigue of the metal, the sound quality will gradually deteriorate. In addition, because the player's hand sweat penetrates into the inner layer of nylon silk, the silk string layer in the strings will undergo qualitative changes, which will also affect the timbre of the guzheng. Therefore, in general, after the strings in the high-pitched area have been used for 100 hours in total, the actual conditions of the strings of the cultivator can be replaced with new strings.

4. Several reasons for broken strings

1. The pitch exceeds the design standard

2. Qinma is too far from Yueshan

3. There are burrs on the strings on the piano code

4. Too much pressure

5. The strings themselves are defective

5. How to replace the strings

1. First, pull out the broken strings from both ends.

2. According to the number of turns of the strings wound on the pegs, use a wrench to loosen the corresponding number of turns counterclockwise, and align the holes on the pegs perpendicular to the bottom surface of the tuning box.

3. Select the same type of strings, pass through the "S"-shaped sound hole, enter through the string hole on the right side of Yueshan through the panel, and pass through the hole of the string pin, more than about 1.5CM.

4. Press down the excess part and stick it tightly to the pegs, and draw all the excess strings into the tuning box, and wind the strings from the outside to the inside from the top of the pegs counterclockwise (1-5). String 3-2 turns. 6-16 strings, 2-1 turns 17-21 strings 1-0 turns).

5. Use your fingers to twist from the inside to the outside to form a loop on the innermost side of the string stud, hold the string with the other hand, and use a wrench to tighten the string stud clockwise to a suitable position.

Key Points:

1. One top should press the end of the string well and stick it close to the stud, otherwise the exposed end of the string will have noise when playing.

2. The strings must be perpendicular to the first contact point of the string eye and the stud, otherwise the guzheng will easily be out of tune.

3. The wound strings must be laid flat on the pegs from the outside to the inside. Do not wind the strings together to form a group, otherwise, when tuning the strings tightly, there will be no response and the strings will break.

6. What to pay attention to when installing strings (changing strings)

  1. First, remove the broken strings wrapped around the pegs, then cover the broken pegs with a tuning wrench, and turn back the same number of turns of the strings, so that there is enough room for the new strings to be tightened.

  2. After the string tail is pierced through the nail hole, it should be bent inward, so that the subsequent strings can buckle and press the string tail, so that they are interlocked.

  3. Do not rest the bridge on the bridge when calibrating the strings. When the tension is close to the tightness of the adjacent strings, the strings are lifted and placed on the bridge. This approach is not easy to damage the strings at the resting point. It also equalizes the string tension.

  4. The treble can be offset by 50-100 cents from the standard pitch, and then the strings are pressed and vibrated on both sides of the bridge to allow the strings to fully extend to the standard pitch.

7. How to properly maintain the strings and prolong their service life

1. The high-pitched strings of the zheng are easy to break, and 1-9 strings can be purchased as spares. The bass strings are generally not easy to break. If the strings are broken, they should be replaced immediately.

2. Always tune the pitch in order to maintain the tension of the strings and the purity of the timbre.

3. The strings are made of steel wire wrapped with nylon. If you get wet in the rain or sweat too much, the steel wire inside will rust, the strings will turn yellow, and they will be easy to age. Usually do not play the zither with wet hands, do not wipe the strings with a damp cloth, do not scrape the strings with a knife or other hard tools, use a soft brush for dust removal, and the dust should be disposed of in time.

4. Before playing the zither, wash your hands and dry them to prevent water, sweat, oil, etc. on your fingers from sticking to the strings, making the strings dirty or rusted and shortening the service life. In order to prevent dust, it is best to make a The zither or the zither cover, and the zither cover (cover) is closed at the end of the playing.

5. Usually fly the kite indoors, do not get exposed to rain, do not expose it to the sun for a long time, and do not place it in an extremely dry environment such as heating.

6. If you don't play the zither for a short time, don't loosen the strings or remove the piano code, as long as it is moisture-proof, sun-proof, and dust-proof, not directly on the ground or hanging on a damp wall. When the humidity is heavy, put the zither in the box and put the desiccant in the box.

7. When moving the bridge for tuning, use your hand to touch the strings up first to reduce the pressure of the strings on the bridge before moving, so as not to damage the strings and scratch the panel.

8. Frequent use can keep the strings and resonance body of the instrument in a good vibration state for a long time, which is beneficial to the instrument.
