The Xiao Tradition

Blown vertically and without a membrane, the xiao is quiet, at home in literati qin duets and in the nanyin halls of Fujian

Xiao

Time and place

Single-tube vertical flutes existed in the Han dynasty; the Tang and Song knew them as chiba and xiaoguan, and the Ming and Qing fixed the form called dongxiao. It settled in two places: the silk-and-bamboo and qin-and-xiao gatherings of Jiangnan, and the nanyin halls of Quanzhou and Xiamen in Fujian.

What happened

The xiao is quiet, suited to halls and courtyards rather than open-air drumming. From the Ming onward it paired with the qin, and qin-xiao duets became a hallmark of literati music. In Jiangnan sizhu the dizi takes the fast sections and the xiao the slow ones, the two bamboo tubes trading places. Nanyin fixed the xiao, pipa, sanxian, erxian and clappers into a standard ensemble, its dongxiao keeping the old ten-node, nine-joint construction.

Musical features

The dongxiao is a bamboo tube blown vertically through a U- or V-shaped notch, with five holes in front and one behind, and no membrane. Its range is about two octaves, mostly used in the middle and low register, and it depends on breath rather than volume. Techniques include abdominal vibrato, stacked notes, strikes, gift notes, trills, slides and finger vibrato; phrase ends are often left to fade. Compared with the dizi it has no buzzing membrane, a darker and rounder tone, and one instrument can serve several keys.

What to listen for

Hear the breath first, then the closing and emptying at phrase ends. A xiao long note is not flat: abdominal vibrato makes pitch and volume rise and fall slowly. Nanyin phrases are more archaic, with few ornaments and a tight fit with the clappers. The library's Zizhu Diao from Suzhou, Suo Luo Lian from Quanzhou and Zizhu Xiao from Shanghai are a Jiangnan tune, a folk dance and a song about the instrument, not xiao recordings.

Common misunderstandings

The xiao is often confused with the panpipe, or described as a vertical dizi. A paixiao is a set of pipes with one note each; a dongxiao is a single tube with six holes. The difference from the dizi is not just horizontal versus vertical: the dizi has a membrane, more volume and showy technique, while the xiao has none of these and prizes restraint. Nor is the xiao only for sadness; it takes light sections in sizhu and nanyin.
