Abstract

The invention discloses a bamboo erhu (a two-stringed bowed musical instrument), which includes a neck, tuning pegs, a resonator body and a base. The neck, the tuning pegs, the resonator body and the base are all made of bamboo. The neck is made of thin bamboo such as black bamboo with the root, greenstripe common bamboo, mottled bamboo, Bambusa surrecta, or bitter bamboo. The resonator body and the base are made of large bamboo such as moso bamboo, phyllostachys pubescens or thick-wall bamboo. The resonator body can be designed into a four-piece type, a five-piece type or a six-piece type according to the tone tuning. The four-piece type resonator body is made of four pieces of bamboo and has a resonant and wild tone. The 5-piece type resonator body is made of five pieces of bamboo, and has a muted tone. The six-piece type resonator body is made of six pieces of bamboo, and has a muddled tone. The base is designed into a tile roof type. The bamboo erhu provided by the invention has a good overall vibration effect, with the pitch varying with the size of the resonator body, can meet different tone requirements, has a small contact area and large friction by designing the base into a tile roof type, and is stable and resistant to slide while being played.
