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.

"Why do I often hear the sound of rubbing wood in the performance of the guqin?" In fact, it is not. It may be related to the recording of the guqin playing. In fact, this situation is not obvious when watching the performance live.

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.

But why is the rubbing sound of the guqin so impressive that listeners keep referring to it again and again? This is because in many musical instruments, the original pronunciation of the guqin is low, and the sound of rubbing the strings with the left hand will cover its original pronunciation. If it is another musical instrument, it is easy to eliminate similar sounds during the recording process. noise.
A recording technician who recorded CDs used to complain about this, because the frequencies were so close together that it was difficult to eliminate the harsh noise mixed with the guqin vocals.

For recording equipment, there is no automatic noise reduction for the human ear. When a string grinding sound of the same size is recorded and played back, the audience will perceive the string grinding sound as much louder than when listening to the scene. Therefore, most Guqin CDs can only have no way to protect the friction of the strings.

However, even in the field, the rubbing sound of the guqin is louder than the noise of other instruments. The first reason is that the guqin has no frets or columns, the contact surface is too large, and the sliding grid is long. With such a long left-hand fretting distance, the left-hand fingers need to exert more force in the horizontal direction than other instruments, and this force is greater than other instruments. Therefore, the ancients have a saying that "pressing the strings is like a three-pointed wood", and there will naturally be a larger friction sound at this time.

Secondly, the left-hand vibrato technique of Guqin is very complicated. For example, in the left-hand technique "Yin", there are "Xi Ying", "Sing Ying", "Chang Ying", "Ji Ying", "Slow Ying" and so on, and naturally there are these complex fingerings in "Yu". Therefore, when the complex string vibrating is completed, it may be chanted three to five times around a range, which naturally increases the possibility of guqin friction.

Another important reason is that when the left big finger presses the string, it presses the string with the half-armor and half-meat part, which is very special. Strictly speaking, if only meat is used, the sound of rubbing the strings is less noticeable. However, after mixing the nail, the nail is a relatively hard material and inevitably makes more noise when it comes into contact with the strings and panels.

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. Before 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. Friends with sweat on their hands can apply some dry powder on their fingers in the morning. Category. 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 formal 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 played when playing. Slightly lean towards the side with less friction to reduce the amount of noise rubbing against the strings and face.

3. The left hand must press the strings cleanly and neatly. For example, many guqin players will touch the next string subconsciously when playing the hand sound of the next string, so that they can quickly find this string when playing. strings, which just 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 do not need fingernails to press the 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.

There are some experienced guqin players who also make some rubbing sounds, but this kind of rubbing sound actually indicates the traces of finger movement during the performance. This kind of sound is like the occasional stroke of Chinese calligraphers' writing. Although we usually focus on "leaving no traces", sometimes, as long as such traces are not deliberately left, there will be a kind of feeling between the audience and the author. feelings of communication. And this kind of sound seems to be absent. If you really look for this kind of sound, you may not hear it again, because this kind of friction sound is made unintentionally.
