What are the materials of the erhu bow

The main components of an erhu bow are: the bow shaft, the horse tail, the fish, and the screws. Bow rod common materials are arrow bamboo (dyed and original color, a section and two sections), a little more upscale Xiangfei bamboo, and even draw on the violin bow made of high-grade wood, but not very practical in the erhu; horse tail in general, mainly white horse tail, erhu rarely use black and brown horse tail, which is used for the Jinghu and other stringed instruments. In recent years, some of the horse tail is not long enough, there are low-grade bows, with the pulling method to lengthen it root by root, saving the cost, harming the user; fish material is diverse, plastic, mahogany, and even with bone, teeth and other materials to achieve the purpose of the high price, as long as the grade of sturdy materials, does not affect the use of the high and low; screws, needless to say, in general, are mostly brass, practical and wear-resistant, and rarely useful for other Precious metals. A good erhu bow to fine craftsmanship, not crooked, not warped, eat up the strength, to put it bluntly is, and good-looking, and practical.
