The fast bow is a difficult movement in the erhu skills, and it is a difficulty in the basic skills of the erhu. So how does the erhu pull the fast bow? The following has organized the method of the erhu to draw the fast bow for your reference.

The method of erhu pulling the fast bow: the four-step method of pulling the fast bow

The first step. Practice the bow first and play the sustain note with a larger degree of string attachment, which can be practiced on the empty strings.

The method is: put the stringing point of the bow on the middle bow, and rotate the right arm slightly to the right to increase the pressure on the string. The bow is suddenly started, the pitch is played, and the bow is pulled out about ten centimeters and suddenly stops, but the pressure on the strings should always be maintained. If you push the bow suddenly again, you still have to play the pitch, push the bow back to its original position and then stop suddenly, and the pressure of sticking the strings still needs to be maintained at all times. Repeat this practice until you are proficient. When doing this exercise, special attention should be paid to: ① the bow hair should be attached to the string; ② the speed of moving the bow should be fast; ③ the pressure of the bow hair on the string should be maintained from beginning to end and cannot be loosened, even when the bow suddenly stops; ④ When using the bow, maintain a large friction force, and the bow hair should not slide the strings lightly;

Step 2. Without holding the bow in the right hand, practice the fan movement with bare hands.

When practicing, you should consciously place the "axis" of the movement in the middle of the forearm, so that the elbow and the hand become balanced, and the two ends swing evenly from side to side. Repeat until the movement is correct and natural.

Step 3. Hold the bow with the right hand to do the empty string fast bow practice.

The movements are required to be as correct, natural and proficient as the movements of the empty-handed fan, and the pronunciation must be full and clear, and the sixteenth note time is accurate; until you are proficient.

Step 4. Do the exercises with both hands (Note: The selected tone should be relatively simple, which is convenient for practice).

Although the fast bow is a right-hand skill, it is inseparable from the close cooperation of the left hand in order to play it clearly and granularly. Therefore, the cooperation of both hands is an important part of fast bow training. In fast bow performance, the right hand is the active factor. The speed of the rhythm, the beginning of the sentence, and the change of strength and weakness are all mastered and controlled by the right hand. When playing, it must be done: ① the time value of the sixteenth note is accurate and uniform; ② the pitch of each note must be clear and decisive; The left hand is a passive factor, and the requirement for it is to "point" the finger and align with the beginning of each sound of the right hand. No matter how complicated the sound pattern is, or how difficult it is to change or jump the handle, it is not allowed to lag the action and stagger from the pitch of the bow.

The method of erhu pulling fast bow: precautions for erhu pulling fast bow

1. Blindly pursuing speed, and finally pulling the fast bow is nondescript. It should be practiced slowly, in order to achieve good results.

2. The bow cannot be kept "flat-straight". It is manifested in that the adjusting screw of the bow head moves obliquely or in a circle when playing a fast bow.

3. The string degree is low. Every sound of Kuaigong is played into a "jujube-shaped", which makes Kuaigong's pronunciation ambiguous and lacking in granularity.

4. Pull and push bow pronunciation is not balanced. Play the fast bow for a "lame" effect.

5. The two hands do not cooperate well. Often, the left hand lags behind, especially when using the difficult skills of the left hand such as quick handle change or alternate fingers, it is more likely that the "point" with the right hand does not match. This is also an important reason why the fast bow is not clear. In order to ensure that the "point" of the pressing finger is aligned with the "point" of the bow pronunciation, the movement of the left hand needs to have a certain amount of advance. That is to say, after the previous sound is issued, the left hand should prepare for the finger-pressing action of the next sound. Especially when changing the handle quickly, the wrist and tiger's mouth have already started to move before the sound of changing the handle. Another point is that in the fast bow performance, the left hand cannot have a portamento, and the sound should be in a point shape, not in a line shape. In this way, the flexibility and clarity of the fast bow can be improved.
