How do you knead the violin and erhu?

It's just that the fingers are pressed on the strings and fluttering on the fretboard. When the orchestra performs on TV, you pay attention to how the violinist kneades the strings. It is not difficult to knead the strings, and you can basically try it when you practice to level 3. The key is to practice more so that it can be kneaded well.

Problem description: How to knead slowly. Analysis:

The most fundamental purpose of kneading the strings is to change the tension of the strings. To put it bluntly, it is to change the tightness of the strings.

Regardless of whether it is "pressing" or "rolling", the ultimate goal is what I said above - to change the tension. Some players, and even performers, will achieve an effect similar to kneading the strings by varying the distance at which the strings vibrate. These are used in special circumstances, such as Shandong-style slippery kneading, Henan-style falling kneading and so on.

For learners who need to do kneading exercises, I personally advocate "just press and not knead". Because every change in the position of the erhu (shaking of the headstock, tightness of the barrel and thighs) can change the wave frequency of the sound vibration. The string pressing is more stable than other methods, and it is more suitable for the practitioner to knead the string.

Let me give you my personal opinion on the slow kneading you raised.

No matter what the skill is, it is impossible to learn it by eating a steamed bun, and it needs to be achieved with correct and long-lasting practice. In the case of ensuring the stability of the sound quality of kneading, it is necessary to practice in stages from slow to fast.

First of all, you have to prepare a rhythmic machine to practice at a speed of 80 beats, kneading 2 beats and 2 beats of the bow.

After becoming proficient, increase the speed of the rhythmic apparatus and practice with the frequency of kneading 4 beats or kneading 8 beats after mastery.

Don't be proud at the beginning of the practice, try to record your own kneading with a tape recorder, and listen to see if the pronunciation is even and the kneading force is soft.

The above are all family words, if there is any injustice, please advise.

Finally, I wish the friends of "Niu is thinking of pouring" a speedy success!

There are four main technical forms of kneading: tumbling, pressing, kneading, and slippery. They have different forms and functions, and they are an important technical reserve necessary for the basic movements of the left hand to enter the artistic expression. So how do you knead the strings of the erhu?

The method of erhu kneading the strings is to complete the part function of the action

The main function of the shoulder to wrist in the tumbling motion is stable static support. The first joint of the index finger, middle finger and ring finger is completed with flexion and extension function with the trembling palm to make an upward and downward movement, when the palm is raised, the first joint of the kneading finger is driven to straighten, so as to produce a slightly lower sound than the baseline of the sound ling, and when the palm is down, the first joint of the kneading finger is driven to bend, so as to produce a slightly higher sound than the baseline of the pitch. During the tumbling action, the first joint of the kneading finger can not be reversed, so as to ensure that the natural arm weight can be reasonably released during the action.

Erhu kneading method 2 action framework

Compared with the basic tone movement, the stable support function of the shoulder and arm frame is more prominent.

1. Under normal circumstances, the arm can not move up and down, and the wrist can not move up and down, and the wrist is only the "axis" of kneading the strings, but it must be relaxed.

2. Compared with the basic tone pressing action, kneading the string fingers should not be too heavy.

3. Compared with the basic string frame, the wrist can be slightly raised when kneading the strings to increase the movement space of the kneading fingers when kneading the strings.

4. When the palm is raised, when the first joint of the kneading finger is straightened, touch the string with the fingertip at this time, and when the palm is down, when the first joint of the kneading finger is bent, touch the string with the fingertip at this time.

5. It is impossible for the little finger to be completely rolled and kneaded, because the finger is straight when the little finger is pressed on the string, and the first joint is not bent, so the little finger is a combination of rolling and pressing to knead the string.

6. From the perspective of the mode of action, it is a way to change the length of the string and emit sound waves.

The method of erhu kneading the strings is the range of movements

The amplitude of action is directly related to the shape of the sound waves, the tendency of emotions and the changes of **, which are jointly subject to the needs of the work.

Erhu kneading method 4. Action speed

The speed of the finger stretching determines the density of the sound wave. In the performance of **, the density and amplitude of sound wave changes also have modal functions, but there is no inevitable mutual constraint between the two.

A single up-and-down velocity change does not change the functional part of finger flexion and extension. Sound waves carry changes in amplitude and density at the same time, and the technical conditions related to amplitude changes need to be adjusted at any time.

How to knead the strings of the erhu

1. The left hand must be relaxed, keep in a natural state, the fingers are naturally bent, the hand should be in the shape of a half-clenched fist when kneading the strings, the palm is downward, and the back of the wrist joint is slightly convex, so that the left forearm and the piano crutche, the forearm and the upper arm, the upper arm and the armpit line, the piano column and the vertical line reach four 45-degree natural angles, so on the basis of ensuring the correct sitting posture and pulling posture of natural relaxation, and the standard string pressing action, you will practice kneading the strings.

2. When I start practicing, my left hand feels very raw, that's for sure, after all, the left hand is not as flexible as the right hand. To practice slowly, make full use of the natural inertia to use the index finger, middle finger, and ring finger of the left finger to do activities on the strings, and touch the strings at the rich flesh behind the fingertips, the specific operation is as follows:

3. Take the index finger as an example, the hand is in the shape of a half-clenched fist, the palm is downward, the first joint of the index finger is extended directly after the nail, and the finger is pressed on the standard phoneme.

4. Then the palm of the hand is like a fan, rotating downward from the palm, the wrist joint fan down about 60 degrees until the palm is vertical, then the first joint of the finger pressing the string changes with the angle of the palm downward fan changes the joint axis and bends, the joint bends at the same time the finger surface and the fingertip roll to a slightly lower place, so that the string changes the length and at the same time gets the pressure force when the hand hems, which completes half of the action of kneading the string.

5. Next, the palm of the hand is raised again, and the straightening of the first joint of the fingers makes the finger surface roll back to the slightly lower pitch above the pitch limit. With the wrist joints swinging flexibly and the finger joints flexing freely, the exercises move from slow to gradually accelerated.

You'll gradually become proficient in going from one slow wave to a dozen fast waves per bow. Mid-frequency kneading is mostly used for songs that are a little more relaxed.

6. Pay attention to the fact that when practicing, the palms are swinging up and down instead of left and right, so as to develop good habits. Practice the right way, otherwise the wrong way will be difficult to change.

When kneading the strings, the left hand must be relaxed, keep it in a natural state, the fingers are naturally bent, the hand should be in the shape of a half-clenched fist when kneading the strings, the palm of the hand should be downward, and the back of the wrist joint should be slightly convex, so that the left forearm and the cane, the forearm and the upper arm, the upper arm and the armpit line, the column and the vertical line reach four 45-degree natural angles, so on the basis of ensuring the correct sitting posture and pulling posture of natural relaxation, and the standard string pressing action, you will practice kneading the strings.

3.For beginners, the kneading force is very small, and the hand is stiff when the strength is emphasized. The first practice of kneading the strings is mainly based on flexibility, and the posture should meet the requirements, and the wrists and fingers are quite proficient, and the fingers gradually increase the strength.

When you are usually fine, you can also move your left wrist joint more.

Fingers on a certain phoneme on the string fan-shaped rolling is called "kneading the strings", kneading the strings will produce a wavy-like sound, the proper use of kneading strings can make the melody more singable, enrich the erhu playing skills, if the change is the first door to improve the expressiveness of the erhu, then the kneading of the strings is the second gate.
