Beginners learning erhu often have irregular bow movements, unsteady bow speed, unstraight bow direction, fast and slow, up and down, left and right, or fast draw, slow push, and strong draw. , The common faults of weak bow, heavy bow root and light bow tip.

These common faults are to be reminded in time:

Explain the root cause of these problems, let the children stabilize the bow first, and distribute the bow sections reasonably according to the rhythm. At the same time, inspire the students to straighten the bow and stretch it forward to the right, so that the bow is at right angles to the strings. The root of the bow should be believed in the bow. The farther the root of the bow is away from the qin barrel, the greater the force. On the contrary, the closer to the qin barrel, the force will gradually weaken, so that the strength of the bow can be uniform and round.
