Erhu string changing skills are very important, and more research is needed!

Erhu string changing means that the bow hair rubs one string and turns to rub the other string. There are no more than two situations to change the strings: one is to change the strings when the erhu is used to change the bow, and the other is to change the strings while the bow is running. These two kinds of string changes require the timing of the notes to be deducted, and the transition is natural.

For beginners, because the action of changing strings is one-sidedly dependent on finger strength and insufficient wrist strength, the finger force is passive in changing strings. When changing the strings, the erhu often snaps to a sudden stop, or slams the strings, and the problem of changing strings in a fast melody is still prominent. Therefore, the mutual coordination of wrist strength and finger strength is very necessary for changing strings. When changing strings, attention should be paid to the mutual coordination of wrist strength and finger strength. Quick bow is usually used to deal with fast-melody music, and it is one of the basic means to improve the expressive power of erhu.
