Correct bow holding is the foundation of erhu bowing, and wrong bow holding will inevitably affect the quality of erhu bowing and the pronunciation of the erhu. Next, I will show you the correct way to hold a bow.

Bow pressure:

The specific method of holding the bow is to hold the bow rod with the thumb and index finger of the right hand, and insert the middle finger and ring finger between the bow rod and the bow hair from the lower part of the bow rod. The bow rod is placed between the first and second joints of the index finger, the inside of the belly of the big finger is in light contact with the bow rod, the second joint of the big finger slightly protrudes outwards into a natural and relaxed state, and the tip of the thumb is facing the forefinger The second joint is in the direction of the fingertips, and the middle and ring fingers are close to the arch hair.

When the bow is moved, the joints of each finger of the right hand are flexibly adjusted and flexed and extended at any time with the change of the position of the bow. It is particularly important here that the thumb should not put excessive pressure on the shaft when the bow is being carried, and the thumb and index finger should not be holding the shaft tightly. The inner side of the thumb is the fulcrum to turn back and forth naturally.

Vibration of the strings:

If the thumb exerts force, the first one will cause the tension of the hand muscles and the whole hand, and the second thumb will put pressure on the bow shaft, which will inevitably cause the bow shaft to be pressed against the side plate of the piano barrel, and part of the bow hair will be pressed on the bow shaft. On the strings, another part of the bow hair is pressed against the top of the piano. We know that the vibration of the erhu strings is caused by the friction between the bow hair and the strings. If the above wrong bowing method is used, the bow rod will be pressed against the side plate of the violin barrel and the noise will be generated during the performance. It will cause a waste of energy; in turn, part of the bow hair will be pressed on the panel of the piano barrel when the bow is carried, and this part of the bow hair will not only not be able to rub against the strings to generate vibration, but will also cause a waste of energy. This kind of sound produced by the bow rod pressing on the side plate of the qin barrel and only part of the bow hair pressing on the strings to vibrate the strings when the bow is carried is a partial, woody and inelastic sound. We know that any physical tension in erhu performance hinders the development of erhu pronunciation and erhu playing techniques. Therefore, the tension of the right hand and the fingers of the right hand, the pressure of the bow rod on the side panel of the qin barrel, and the dead pressure of the bow hair on the strings will affect the vibration of the erhu strings and make the erhu pronunciation worse. The physical tension in these performances is superfluous and unnecessary for erhu performance.

When holding the bow, each finger of the right hand and even the entire hand should be natural and relaxed. In order to achieve the relaxation of the bow, it is very important to avoid the practice of holding the bow with the right thumb and index finger. When holding the bow, do not use your fingers and hands to grab or hold the bow too actively, which can easily cause unnecessary tension in the fingers and hands of the right hand. When holding the bow, you only need to consciously put the bow on the natural and relaxed right fingers and hands, so it is easy to remove the tension caused by the right fingers and hands actively holding the bow. This is correct. Bow holding is very important.
