The exercise here is a movement exercise of the index finger, which uses a "finger shift" action without changing the handle. Under normal circumstances, during the movement of one finger, the arm, wrist, tiger's mouth, and thumb of the left hand remain in place (do not move), and the movement of the wrist should be minimized.

Note: The finger-shifting exercise here is to practice the "shift" of the fingers. The purpose of the exercise is to try to avoid the production of portamento on the real piano, especially the major second degree of portamento is very unpleasant. Through such exercises, the independence and sensitivity of the index finger will be enhanced.

The figure below shows the finger movement of the index finger in the second position of the outer string

After practicing on the sound bar to get a sense of distance, practice in-depth on the real piano. If there is portamento on the real piano, you should carefully understand whether the "finger-moving" movement is balanced, whether the fingers are lifting the fingers, etc. You can go back and practice repeatedly until you can't hear the portamento on the real piano.

Note: In order to improve the effect of the exercise, the practice method of retaining the fingers should be used as much as possible. For those with small hands, only the middle finger can be retained for practice. If you can complete the practice method of retaining the fingers, you will be able to move the index finger on the real piano with confidence.

The picture below is the finger movement of the index finger in the second position of the inner string

The picture above shows the action of "moving the finger" (moving a minor second) with the index finger of the inner string in the key of F major (6.3 string), which is a typical application example.

In the exercise, keep the middle finger (or keep 23 fingers) to practice, the method is the same as the above example.

Erhu Middle Finger Shifting Exercise

The following is a static "finger shift" exercise with the middle finger in the way of retaining the finger. When practicing, keep the index finger and the tiger's mouth steady and minimize wrist movements. Through such exercises, the independence and sensitivity of the middle finger will be enhanced.

The picture below is the movement of the middle finger in the first position of the outer string

When practicing, keep fingers 1-3-4 on the corresponding holes on the phoneme stick. When the middle finger is moved up, the fingertips should be able to correctly and elastically press the intonation.

Note: After practicing on the sound bar, you can practice on the real piano. At this time, you can lift 3-4 fingers to judge whether the pitch of the middle finger is correct in different positions.

The picture below shows the "moving finger" action of the middle finger while keeping the index finger

During the exercise, when the middle finger moves down, try to maintain the stability of the tiger's mouth, relax the wrist and finger joints, and balance the force. When the middle finger is moved down to the highest position, try to maintain the arc of the middle finger joint as much as possible.

Erhu three finger movement practice

The following is a static "finger shifting" exercise that retains the ring finger under 1-2 fingers. When practicing, try to keep the tiger's mouth as stable as possible.

The picture below shows the finger movement of the ring finger of the first position of the outer string.

The exercise in the picture is to use the method of retaining the fingers, that is, to keep all fingers 1-2-4 on the phoneme stick, and move the ring finger. After practicing on the sound bar, you can practice on the real piano. At this time, it is not necessary to keep the pinky on the string. If portamento appears during practice, go back and practice repeatedly until you can't hear portamento on the real piano.

Note: If the little finger is short, you can lift the little finger first for practice.

The picture below shows the movement of the third ring finger in the key of D (1 5 string).

The fingering of expanding the minor third under the third ring finger is used a lot. When practicing, keep the index finger and move the ring finger. In practical applications, sometimes only the tiger's mouth is fixed, and the index finger moves slightly downward.

Erhu pinky finger shifting practice

The following are "finger shifting" exercises that retain the little finger under the finger, and they are two of the most commonly used examples. When practicing, try not to pull the reserved fingers (such as the index finger and ring finger) to maintain and stabilize the hand shape. The purpose of static training of little finger "finger shifting" is to enhance the strength and independence of the little finger and improve the balance between the little finger and other fingers.

Movement of the little finger in the first position

Due to the wide finger spacing of the erhu in the second position, especially the major third pressing between the ring finger and the little finger, it is often easy to make the little finger lower. The exercise on the left is to train the expansion ability between the little finger and the ring finger.

Note: The practice can start at a slow speed, and then speed up the speed and frequency of finger movement after familiarity. When the little finger and the ring finger are in a major third, the little finger should be pressed in place correctly to avoid the low tone on the real piano. When practicing, try to keep the relative stability of the tiger's mouth and the left hand.

Movement of the little finger in the third position

The above picture is an example of the external string of D major, to practice the extension ability of the little finger. When practicing, you should also pay attention to maintaining the relative stability of the tiger's mouth and the left hand shape.
