There are four main technical forms of serial kneading: rolling kneading, pressure kneading, digging kneading and sliding kneading. They have different forms and functions, which are necessary and important technical reserves for the basic movements of the left hand to enter artistic expression. So how do you knead the erhu? What are the methods of kneading erhu strings? Below, I sorted out the methods of kneading erhu strings for your reference.

The first way to knead the erhu strings is to complete this part of the action.

The main function of shoulder to wrist in rolling action is stable static support. The first joints of the index finger, middle finger and ring finger are lifted up and down with the flexion and extension function. Exercise, when the palm is raised, drives the first joint of the kneading finger to straighten, thus making a sound slightly lower than the pitch baseline. At the same time, the first joint of the kneading finger is driven to bend, thus making a sound slightly higher than the pitch baseline. In the process of rolling and kneading, the first joint of the string can't bend backwards to ensure that the natural arm weight can be released reasonably during the exercise.

The second action frame of erhu string kneading method

Compared with the basic pressing action, the stable supporting function of the shoulder arm frame is more prominent.

1, under normal circumstances, the arm can't go up and down? Can't you move your wrist up and down? Move, the wrist is just the "axis" of the string rubbing action, but relax.

2. Compared with the basic bending action, string rubbing means not to touch the strings too heavily.

3. Compared with the basic string press, the wrist can be slightly raised when the string is twisted, so as to increase the action space of the fingers when the string is twisted.

4. Raise your palm, and when the first joint is straight, touch the strings with your fingertips under your palm. When the first joint bends, you touch the strings with your fingertips.

5. It is impossible for the little finger to roll completely, because when the little finger presses the string, the finger is straight and the first joint is not bent, so the little finger is combined by rolling.

6. From the action mode, rolling is a way to change the chord length and emit sound waves.

Erhu String Kneading Method: Three Action Ranges

The amplitude of action is directly related to the shape of sound waves, the tendency of emotions and the change of music, and * * * is also subject to the needs of works.

The method of kneading the erhu strings-four kinds of action speeds

The speed of finger flexion and extension determines the density of sound waves. In music performance, the density and amplitude of sound wave changes also have a mode function, but there is no inevitable mutual restriction between them.

Single up and down? The speed change does not change the functional parts of finger flexion and extension. Sound waves have both amplitude and density changes, so it is necessary to adjust the technical conditions related to amplitude changes at any time. ?
