The sound of the guqin is beautiful and beautiful, and it has the power to penetrate people's hearts. When I hear the sound of the guqin, I feel that the world is quiet, as if I have traveled back to ancient times.

A friend asked me before: "Why do I often hear the sound of rubbing wood in the performance of the guqin?" Actually, it is not. It may be related to the recording of the guqin playing. This situation is not obvious.

The so-called "rubbing sound" refers to the sound of sliding with the left hand, touching the strings (called "range" in guqin performance) when the sound is pressed, and the sound when the fingers touch the panel and the strings. This sound is not part of the music, but it is also inevitable.

So in the process of playing the guqin, how to reduce the fricative sound of the left hand on the surface and strings? There are five main points to note:

1. When we play the piano, we must make sure that the fingers touching the strings are dry and lubricated. After washing our hands, dry our hands and let them dry for a while to make them completely dry. Friends who have sweat on their hands can apply some drying powder on their fingers. . If there is an appeal problem, the left hand tends to make a "squeak" sound when playing the away hand.
2. When we play some songs, we need to press the strings with the left hand, especially when pressing the thumbs. The normal requirement is to press the strings with half the nails and half the meat, but the friction between the meat and the nails on the strings is different, and it can be slightly biased when playing. The side with less friction to reduce the noise produced by friction against the strings and the surface.
3. The left hand must press the strings cleanly and neatly. For example, many guqin players will touch the next string subconsciously when they play the hand tone of the next pressing, so that they can quickly find this string when playing. Precisely this adds to the noise of the rubbing strings. This is a bad bug that must be corrected in order to reduce unnecessary noise in future playing.
4. Another problem is that we don't need fingernails to press strings with our left hand. The nails of the left hand must be trimmed in time, because when the strings are pressed, especially in the middle and lower positions, it is easy to touch the front string, and there will be noises that scratch the strings. . One way is to trim the nails of the left hand from time to time, and the other way is to move back a little when the strings are pressed to prevent them from touching the strings in front of them and causing unnecessary noise.
5. Finally, it is important to say that the unnecessary noise when we play the guqin is caused by the lack of solid basic skills and techniques. For example, your wrists and arms are not relaxed enough, not dexterous enough, and if you play the hand and chant stiffly, there will definitely be noises, and there is no charm, because they are all suppressed by the noise of friction. Therefore, it is necessary to learn the basic knowledge and master the basic skills.
