The bow holding point formed by the index finger and the thumb should be fixed no matter when the bow is drawn, pushed, changed or changed. When the bow is moved, the whole right hand takes the bow holding point as the axis, and the thumb and the index finger are related around the axis. sector rotation. In the practice of playing, you should develop the habit of consciously abiding by the symbols, and remember some common bowing symbols, otherwise the whole bowing sequence will appear chaotic and detrimental to the performance of the musical image.

Except for the slurred symbols clearly marked in the score of Erhu practice, other symbols (including finger movement symbols) are only marked where necessary. For unmarked notes, inferences are made from the preceding and following playing symbols. To play the fast bow, you must start with the slow bow first. Only by pulling the slow bow stably, flatly, straightly, and implicitly, can the muscles of the relevant parts of the right hand deepen the memory of the subtle movements of bowing priorities. To learn to play fast bows, these muscles can gradually adapt to the needs of fast bow movements, and then gradually increase the speed after pulling to a certain extent.

For music with dense tone patterns, compact rhythms and fast melody, the bowing method of one note and one bow is usually used. The fast bow is widely used in modern instrumental music and is a basic means to improve the expressive power of the erhu.
