A Geography of Sound

Bamboo instruments outnumber all others in Yunnan for a plain reason: the material is at hand. But bamboo is more than a material. Knowing which season to cut, which segment to take and how many nodes to leave is a body of local knowledge in its own right.

Bone and hide carry the memory of hunting and herding. The Yi make a double-piped bawu from goose bone; the Wa cut a reed into an ox horn. A bone flute is, in part, an imitation of animal calls.

Metal points to smelting and trade. Brass reeds, gongs and cymbals mean that technology and goods once travelled these mountain roads from far away.

An instrument’s name often records how it was first heard.

The Yi awu is named after the sound it makes — something close to “a-wu, a-wu”. Folk stories tie its origin to a dragon pool, a cowherd and a plea for rain, and so it is played at rice-planting time.

The Dai hulusi is usually rendered in Dai as bilangdao. The syllable bi names the whole family of reed pipes: the name tells you how it sounds before it tells you what it looks like.

Whether a name echoes wind, birdsong or a particular mood usually says more about an instrument’s place in daily life than its shape does.

Treating an instrument as equipment for stage performance is an assumption inherited from theatre.

In Yunnan’s villages an instrument works more like social infrastructure. The lusheng organises steps and processions at festivals. The elephant-foot drum wakes the village at dawn during Water-Splashing Festival. The Nu bamboo horn sounds only at a man’s funeral, to announce the death and open the road. The Yi yueqin carries courtship through the night of the Torch Festival.

These instruments take part in household decisions, in claims of identity, in the handing down of memory. Who may play, on which occasion, and for whom — that is already a description of social relations.

The elephant-foot drum is not exclusively Dai; it is played, with variations, by the Jingpo, De’ang, Achang and Wa. Bronze cymbals and gongs run through the wind-and-percussion music, dance and ritual of the Han and many minority peoples alike, which is why assigning them a single ethnic origin is misleading.

The same holds for the frog and sun motifs cast into their bodies: one symbol grows different meanings as it is explained by different communities.

A culture is not an island but a continuous act of translation. An instrument travels the mountain roads, changing its name and altering its shape at every stop, and remains recognisable all the same.
