Finger movement refers to the various pressing movements of the left finger on the strings. It is an important part of the basic training of the erhu.

The most important thing in playing a musical instrument is the cooperation of both hands, and the erhu is no exception. Only when the fingers of the left hand and the bow of the right hand cooperate with each other can a good tune be drawn.

Finger movement refers to the various pressing movements of the left finger on the strings. It is an important part of the basic training of the erhu. Since the erhu does not have keys or grade marks like the accordion and pipa, it relies on the left finger to touch different parts of the strings. Since the length of the strings determines the width of the pitch, the shorter the strings, the narrower the pitch. The distance between the fingers of each erhu is different, which brings more difficulties to the finger movement.

The correct way of finger movement depends on the correct posture of holding the piano. The first thing to note is that the three parts of the left hand form about 45 degrees": that is, the big arm and the left chest form about 45 degrees, the forearm and the piano rod form about 45 degrees and The second and third sections of the fingers (counting from the root of the finger) and the strings (in the direction of the daughter) form about 45 degrees. Specifically, the upper arm should hang down properly, the elbow should sink down, the forearm should not be raised horizontally, and the tiger's mouth should be held. The violin maintains the necessary looseness, and the fingers are slightly bent downward, and the whole hand is a loose half fist. The shape of the hand creates favorable conditions for the left hand to touch the string accurately and sharply; when the finger touches the string, the part between the finger pad and the fingertip should be pressed, and it should be lightly placed on the string. , it should return to its original position naturally and swiftly. This kind of elastic falling together, on the surface, means that the finger is moving, but in fact it is dominated by "inner energy", which in turn originates from the whole harmonious and natural holding of the qin. left hand.

The mistakes that beginners tend to make when learning to press the strings are: the arms are raised too high, the tiger's mouth is pinching the piano rod too much, and the four pressing fingers are stretched straight and not curved. Some people use their knuckles to touch the strings when pressing the strings, instead of the balls of their fingers. Some people lift their fingers high when they leave the strings after pressing the strings. This kind of incorrect finger movement makes the whole string pressing action very stiff and slow and lacks elasticity. Even though the right hand is more proficient in bowing, the sound is still muddy and confusing. If the above incorrect movements are not overcome and allowed to develop, these problems will be consolidated. Even if one is determined to correct them, it is actually a little more difficult than learning and mastering a new technique.

Therefore, in order to train the flexibility and accuracy of finger movement, we must first check whether the finger movement method is correct. To train the accuracy of finger movement, on the one hand, the posture should be correct. The strength of the ear is the basic guarantee for obtaining the intonation of the strings. Even if there is a slight deviation in the finger spacing when pressing the string, the ear force can adjust the finger spacing to the accurate pressing position at this moment. Although the finger distances held by each sound area on the erhu are different, as long as you practice for a certain period of time, the corresponding finger distances will form an instinctive "conditioned reflex" under the control of the ear force.
