The fingers themselves are prone to noise. The so-called noise is the sound other than the sound produced by the normal vibration of the string. Under normal circumstances, there are two basic ways to generate noise, one is friction and the other is impact. Therefore, we can consider reducing the generation of noise according to these two points.

The requirements for the finger speed of the wheel fingers are relatively high. Slow down, and the fingernails will collide with the vibrating strings, making some noise. But if you get the hang of it, plucking the strings when they vibrate to a certain position will minimize this sound.

In addition, the surface of the nail should be kept as smooth as possible, and the string should not be inserted too deep, otherwise the friction between the nail surface and the string will produce noise. Another very important detail is to adjust the angle of the fingers in time. After having certain basic skills, each finger should have the function of independently adjusting the angle within a certain range. This adjustment ensures that the strings are always touched with the flat surface of the fingernail, rather than the side of the fingernail, which will also avoid noise.

Noise is unavoidable, what we need to do is to minimize the volume of the noise so that it does not affect the music. According to this idea, it is also possible to increase the intensity appropriately when playing, so that the music will cover up the noise, which is also helpful for the improvement of the overall sound quality. However, this method has some limitations, and it is powerless in some occasions where weak playing is required.
