The correct method of pressing erhu strings is still liked by many people in life. Mastering fingering is an important secret to playing erhu well. For beginners, the first thing is to come first, and then how to press the strings. Let's take a look at the correct way to press the erhu strings.
Correct pressing method of erhu strings 1 hand shape;
To learn erhu, the first thing to emphasize is the hand shape. The hand shape of the left finger is the posture of the wrist and finger joint when the finger presses the string. Whether the hand shape is correct or not is the premise of the change of standard string pressing action and finger action. The general standard hand type is:
<1> When practicing, first open the jaws of the left hand, and naturally straighten the thumb joint. The piano rod is put into the tiger's mouth, and the fingers, wrists and knuckles are raised in a semi-clenched fist shape. Fingertips are arranged on the strings in turn, and the point of pressing the index finger and the point of holding the piano in the tiger's mouth are on a horizontal line.
〈2〉 In general, the arrangement of fingers is to adapt to the angle of the straight line up and down the strings. The joints of the index finger are the most curved, followed by the fingers below. The key to keeping the right hand shape is that the palm is suspended, just like holding table tennis.
< 3 > The most common problems are the contraction of thumb and knuckles, the grip of the piano rod by the jaws of the tiger, or the collapse of the palm joints and the fingers pressing against the strings, which all affect the force of the left hand, making the left hand too nervous and the fingers lose elasticity.
Generally speaking, hand types vary from person to person. The radians of the palms of people with big hands or small hands are not uniform. For people with small hands, the tiger's mouth should be pressed down appropriately to distance the fingers.
Press the strings:
Strike is the most important fingering method of erhu. The method of pressing the strings is based on the finger joint, and the fingers are lifted and pressed, which is even and elastic. The specific method is as follows:
<1> First of all, it is necessary to make clear the position of the finger pressing the string: the position of the left finger pressing the string is generally the most plump position between the fingertip and the finger surface, so that the finger pressing the string can move up and down flexibly, which is convenient for the finger to slide and knead the string, and is suitable for various playing techniques.
< 2 > Pay attention to the string movements, which are the movements of lifting and closing the fingers. The wrong string pressing is generally understood as the simple downward movement of fingers, and it is easy to understand that fingers pull down strings directly, which will easily lead to stiff fingers and nervous string pressing, and it is more difficult to learn to knead strings and change handles.
< 3 > The actual and correct pressing of strings refers to the inertial action of lifting the root joint to the fingertip. Mastering this inertial action, fingers pluck the strings lightly and flexibly. Therefore, people call pressing the string touching, which means that it explodes at the touch and loosens at the touch, reflecting the concentration of elastic force at the moment when the finger touches the string.
〈4〉 To make it clear how the finger exerts its force, the force of pressing the string by the finger is also called finger force, which is closely combined with the action of pressing the string. The key of finger force lies in the tightness, that is, the force exerted on strings by fingers when lifting them. This force comes from the big arm and the small arm, and the arm force acts on the strings through the support of the chin grip, the fulcrum of the metacarpal joint and the finger contact. So it's not the local movement of the fingers that puts pressure on the strings.
Correct pressing method of erhu strings II. A handle is adjacent to two fingers at intervals, which is nothing more than two degrees, two degrees, two degrees and three degrees. It is the basic fingering that one finger and four fingers form a pure four-degree relationship, and the basic fingering forms four hand types:
1, one, two, three or four fingers are connected to form a two-degree relationship, and other fingers are separated into a two-degree relationship.
2. One, two, one, two and three fingers are connected together to form a two-dimensional relationship, and the other fingers are separated into a two-dimensional relationship.
3. Two-one-one-two fingers are connected to form a two-degree relationship, and the other fingers are separated into a two-degree relationship.
4. 11111 style, 1234 fingers are separated into two degrees, and the empty string and one finger form a two-degree relationship.

Matters needing attention
1, arrange fingering to minimize frequent finger exchange, and it is better to exchange adjacent fingers. The fourth degree is the original natural hand shape. Try not to change the finger that can be changed, and don't avoid the function of the little finger. Be sure to use it in the right place and try to keep the hand shape stable and orderly.
2. Choose a good combination of fingers, give full play to the independent performance of each finger, and combine the traditional one-tone switch to make the note link natural, smooth and clear.
3. The aim of emphasizing fingering is to ensure intonation. Only when the intonation is good can there be different changes in the speed, strength, height, area and position of fingering, and you can make a difference and know something about fingering or touching strings.
The correct method of pressing the strings of erhu III. Basic fingering of pressing erhu strings with left hand.
Among the four fingers of the left hand, only the little finger is different from the other three fingers in the shape of the stringed hand. When the little finger presses the string, first of all, the palm should be completely opened, just like the hand shape when we usually draw the "five" by hand. Then, the index finger, middle finger and ring finger are bent, the little finger is kept straight, the thumb is tilted up, and the string is touched with the outside of the little finger.
When the little finger presses the string, the left hand will be in a tense state, which is normal. If the little finger is not used frequently in a phrase, the left hand should be restored to a natural and relaxed state as soon as possible after the little finger completes the string pressing task.
If the little finger is frequently used in a phrase, the left hand should keep the hand shape of the little finger when pressing the string in this phrase. The little finger is short and weak, so when it presses the string, the other finger must always be placed on the string to assist. Its principle is:
1. Keep your finger pressed on the string in front of your little finger.
2. If the note before the pinkie is empty string, then the ring finger and pinkie should be pressed at the same time. However, we should pay attention to the coordination of "keeping fingers" to avoid unnecessary noise.

First, the health care function of finger movement
Our hands are covered with meridians and acupoints closely connected with the human body and organs. When a certain part of the body is abnormal, the corresponding part of the palm will also change. There are six meridians in the hand, which communicate with all organs, tissues and organs of the whole body, and there are about 99 acupoints (areas), which can reflect the health status of each organ. Massage or pressing these acupoints can almost relieve systemic diseases.
1, thumb: corresponding to lung meridian and cardiopulmonary organ;
2, index finger: corresponding to the large intestine meridian, stomach, intestine, digestive organs;
3. Middle finger: corresponding to pericardium meridian, five senses and liver meridian;
4. Ring finger: corresponding to triple energizer meridians, lungs and respiratory organs;
5, little finger: corresponding to the heart, small intestine meridians, kidneys, circulatory system organs.
Second, erhu finger practice
Whether you are working in the office or at home, or even walking, you can adjust your mood to a relaxed and pleasant level and stretch your fingers easily, which can effectively relieve fatigue and stress, greatly improve your physical condition and promote your physical and mental health in an all-round way. For an erhu lover, it is also very beneficial to improve the skills of finger movement in the left hand.
1, rotate left and right to stretch fingers, palm up, and bend one finger in turn from the index finger. When one finger bends, the other three fingers remain straight. When the ring finger and the little finger do this, they will initially drive the other fingers to flex and stretch independently.
At this time, don't pull the finger that has been driven by the right hand, but let it go, gradually increase the degree of independent bending from tiny bending, and finally achieve independent and flexible bending, thus releasing the linkage action of these two fingers.
Some people think it is unnecessary to play the erhu fingers with the left hand, but as we all know, the interaction between the left hand and the right hand can balance the internal nervous system of the body, and both of them will have an inducing effect whether they move with the left hand or the right hand.
It will also affect the blood circulation and nerve movement of the other hand to varying degrees. If both fingers are stretched with the same finger or different fingers at the same time, the effect will be more obvious. When you stretch your fingers, your mind should be concentrated, and your fingers should have rhythm and strength. Finger stretching can only be done for 5- 10 minutes every day.
2. The greater the hand grip, the more liver qi, and the longer people live. There is a conclusion in the west that the longer the grip strength of the elderly over 70 years old, the more often they should exercise their grip strength. After the age of 40, people's physiological functions begin to age slowly, so we should develop the good habit of keeping fit and benefiting the heart as soon as possible to prevent getting old.
The index finger, middle finger, ring finger, little finger and thumb of the left hand are tightly pinched together. After staying for 10-20 seconds, the fingers are relaxed in turn. After all the fingers are relaxed, relax for 65,438+00-20 seconds, then clench and then relax in turn. In the future, every finger can relax at will, and the mind should be concentrated, powerful and rhythmic. Do it about 10 times a day. After training for a period of time, whether it is physical fitness or the fingers of the left hand when playing the piano, it will inevitably produce miraculous effects.
