- Development
The earliest Xiao appeared during the Han Dynasty (206B.C. -220A .D.), and it was then called Qiangdi, which was popular among the Qiang people in Sichuan and Gansu Provinces. In the 1st century BC, it became popular in the Yellow River region. Later, it was developed into an instrument with six holes, which was extremely similar to today's Xiao.
- Structure
Its structure is quite simple, very much like the flute, but only longer. It is usually made of bamboo. The top is sealed by bamboo. There is a mouth on the top and five sound holes on the frontal side and one hole at the back. Beside, there are other holes that are designed to adjust the tunes, smooth the tones, and raise the volume. Xiao sounds soft and graceful.
