The left thumb slides easily when the violin is kneading

I don't see your posture holding the piano, so I can only say according to my experience: 1. You mainly rely on your left hand to hold the piano, and the left thumb is horizontal up and down, which will lead to the stability of the piano when kneading the strings; 2。The amplitude of the hand is so large that the headstock slides downward.

The main way to hold the piano is to clamp the piano firmly by the chin, and the left hand should gently support the neck of the piano so that the fingers can accurately press the strings and move. You don't need to use much force, just clamp the piano steadily, and the left thumb is up, not held, so that the piano does not slide down when you knead the strings, and the sound of the piano is very soft when you knead the strings.

The main problem is that you are kneading the strings in the wrong position. The main points to note are as follows:

When kneading the strings, the support point and the focus point of holding the piano are mainly focused on the collarbone, and the support of the left hand is secondary. The headstock direction should be slightly above the horizontal plane.

The essence of kneading the string is to put the fingers on the fulcrum of the fretboard, within a certain range of pitch (generally no more than semitones), so that the contact points of the strings have regular, repeated forward and backward movements, so as to change the pitch to obtain the effect of pitch fluctuations. When kneading the strings, the fingers should be kneading the strings in an acute angle so that the second joint of the fingers of the left hand is bent and extended, like the hinges on a door.

When starting kneading, the first step should be in the direction of the headstock. When kneading the strings with the left hand in positions 1 to 3, the thumb should not leave the neck, and the base joints of the index finger should be slightly away from the neck.

Summary. Dear, glad to answer for you. When the violin is kneading, the left hand cannot hold the piano for several reasons:

Left hand grip is not enough: When kneading strings, the left hand needs to hold the neck together and use your thumb and fingers to control the neck and support the body to keep it stable. If the grip is not enough or incorrect, it will cause the left hand to not be able to hold the instrument.

At this time, you need to adjust the posture of your left hand so that the thumb and fingers are held more tightly together, and pay attention to maintaining stability. Lack of strength in the left hand: When kneading the strings, you need to apply a certain amount of force to the neck with your left hand to maintain stability.

If the strength is not enough, it will cause the left hand to hold the piano. At this time, finger strength exercises can be carried out to enhance the strength and flexibility of fingers. Incorrect posture:

When kneading the strings, you need to maintain the correct body posture and left hand posture, if the posture is not correct, the left hand will not be able to hold the piano. At this time, you can find a professional violin teacher to guide you and help correct your posture problems. It should be noted that not being able to hold the piano with the left hand may cause difficulty and discomfort in playing, and will also affect the performance effect.

Therefore, it is advisable to pay attention to adjusting the posture and finger strength when practicing kneading the strings to maintain stability and smoothness. At the same time, you can also gradually master the correct method and technique of holding the piano through many exercises and professional guidance.

How to practice violin kneading strings is as follows:First of all, play the rosin and tune the violin.

Before practicing on the violin, practice the knocking movement for 30s-50s each time, which mainly improves the strength and flexibility of the wrist.

To be precise, you can lean your hand on the case to help you quickly find the feeling of kneading.

Set the bow aside for a moment and make the gesture with your left hand when pulling the empty string.

Put your fingers lightly on the strings and don't press them down.

Using the palm root as the fulcrum, turn your wrist back and forth and let your fingers slide on the strings for 30 seconds <> at a time

This movement should be practiced for a week to get a feel.

After a certain amount of practice, you can press the strings, and at this point you have mastered kneading the strings in the high position.

Once you've reached the low position, simply turn the fulcrum point into the base of your thumb.

The violin, is a stringed instrument. There are four strings in total. The vibrations are generated by the friction of the strings and bows, which are then transmitted to the back plate through the sound column in the resonance box, and the resonances generated by these parts produce a harmonious and bright sound.

The violin body (co-hood box) is about a centimeter long and is made of curved tops, backs, and sides glued together. The panel is often made of spruce and has a soft texture; The back and side panels are made of maple, mahogany, and the texture is harder. Whole maple for headstock and neck, and ebony for fretboard.

Violin kneading technique.

In terms of sound quality, kneading strings can be divided into two types: one is a strong and deep "kneading" string, and the other is a "soft" string that plays a decorative or finishing role on the surface. The former mostly uses the back of the arm as the traction point of the force, and moves regularly and proportionately.

The amplitude and frequency of kneading will vary accordingly with the strength of the tone and the available length of the bow, "because there are four properties of pitch, intensity, length and timbre, where the intensity depends on the amplitude and the pitch depends on the frequency." ”

The latter is used for short notes, finales or in dreamy sketches, and is used to express a romantic kneading technique, which is particularly well connected between the notes produced and is also a beautiful way to express long sentences, and is also commonly used at the end of a weak note, when the wrist kneading reflects its advantages. There are three types of kneading techniques, namely wrist technique, fingering and arm technique.

1.Wrist Method: The wrist method mainly relies on wrist flutter, which sounds euphemistic and beautiful. Generally, kneading the string is to learn the wrist method first, this method The forearm does not move, the wrist is the axis, the hand swings back and forth, and the first joint of the finger moves slightly.

2.Fingering: Fingering relies on the shaking of the finger joints, which sounds soft and soft. This technique is mainly used on the high handle of the violin, and the fingers are pressed on the note to obtain the kneading effect obtained by alternating tight-loose-tight-loose.

3.Arm method: Finally, the arm method is kneading, which mainly relies on the vibrating of the forearm, which sounds enthusiastic and full. This technique is based on the back and forth swing of the forearm, the wrist does not move, and the first joint of the finger moves slightly.
