How to play erhu smoothly?

1. The posture of holding the piano is incorrect, resulting in the arch hair not moving correctly along the direction perpendicular to the strings. Please correct your posture strictly according to the textbook or video;

2. The posture is right, and the bow is not right. The bow should be perpendicular to the strings and close to the body, and the bow hair should always be in a straight line, and the trace rubbed on rosin is a straight line, not a diagonal.

There is a noise, which is generally related to the strength of the bow. At the beginning of learning, the teacher will tell you that the bow should be lifted horizontally and the force should be even, so that the bow should be close to the string, and attention should be paid when changing the bow to avoid sudden force. Don't touch the snakeskin with your nails when you press the strings.

3. Both of the above are achieved, but the strength is too strong to match the bow speed. Slow bowing is the most prone to noise. The correct bow movement is to change the volume at bow speed without adding the upper chord force, that is, without adding the force perpendicular to the bow rod.

Extended data:

The specific method of holding the bow is to hold the bow rod with the thumb and forefinger of the right hand, and the middle finger and ring finger are inserted between the bow rod and the bow hair from below.

Place the arch bar between the first joint and the second joint of the index finger, the inner side of the big toe is lightly contacted with the arch bar, and the second joint of the big toe slightly protrudes outwards into a natural relaxed state, the fingertip of the thumb faces the second joint of the index finger in the fingertip direction, and the middle finger and the ring finger are attached to the arch hair.

In order to relax the grip of the bow, it is very important to avoid holding the bow rod with the thumb and forefinger of the right hand. When holding the bow, don't take the initiative to grasp or hold the bow with your fingers and hands, which will easily cause unnecessary tension between your fingers and hands in your right hand.

When holding a bow, it is easy to relieve the tension caused by the active holding of the bow by the fingers and hands of the right hand, which is very important for holding the bow correctly.
