The piano is built by nature, and the piano is raised the day after tomorrow. The same piano in the hands of different people will develop different timbres. This is the so-called "qin with people".

In the daily care of the Yueqin, it is necessary to take care of the instrument so that it will not be injured or exposed to dust. The top of the Yueqin is made of paulownia wood, which is soft and easy to absorb moisture and inhale dust. When damp, the volume will be weakened, and the vibration of the panel will also affect the sound. Therefore, it is usually necessary to develop a good habit of wiping the instrument frequently and putting it in the back cover or the piano case. In addition, learning to deal with some common problems will also help the maintenance of the piano. Listed below are some common sense for fans to refer to.

1. Easy broken strings: If the strings are often broken at the mountain pass or bridge, it is very likely that there are burrs in the string grooves. You can lightly grind the area with fine sandpaper.
2. String out of the groove: During the performance, especially when the strings are strummed, the strings will be out of the groove. You can use a knife or a fine file to make the string groove deeper. But pay attention to too deep and it will sand strings.
3. Sand strings: There are fret sand strings, please check whether the frets are loose. If the piano is inlaid with steel bars or copper bars, check whether the joints have fallen off one by one. If there is falling off, just apply some 502 glue there. Also, you can check if the fine-tuning screws are loose.
4. Inaccurate strings: If the overall tone is high or low, you can adjust the piano code slightly. The higher the tone, the higher the tone, and vice versa.
5. The sound of the newly replaced strings is easy to disperse and explode, especially the second, third and fourth strings. Therefore, if you need to change the strings, it is best to get used to it three days before the performance, so that the strings can achieve the best effect. If you have to temporarily change the sound, you need to pull the strings more, strum the strings hard, and if possible, wipe the strings with a little oil to reduce noise.
6. The pegs are easy to run, and a small amount of rosin powder or a little water can be applied to the pegs.
7. If the pick is used for a long time, the edges and corners will become red and prone to noise. Smooth it carefully with fine-grit sandpaper and polish with toothpaste. It is necessary to correct the pick frequently, and the performance will be smooth.
