Wot (Bamboo Panpipe) — 5-8 Small Bamboo Tubes of Uneven Length, Each Closed at One Node with a Rounded Mouth, Set Round a Larger Core Tube in Lac; Blown, or Whirled on a String Until It Hoots

"Some trim the tube openings to leave them about half open, which gives a small, high, sweet sound." (Sirindhorn Anthropology Centre, author not named, CC BY 4.0)

Choose small bamboo and cut it into pieces of uneven length, mostly 5-8 pieces. Cut off the node at one end and keep the node at the other. Pare the blowing edge round with a knife.

Choose a bamboo tube larger than the others as the core, to hold, or to tie a string to for whirling it round to make it sound.

Melt lac over a fire; when it is soft and starting to cool, pack it round the tubes to bind them together, with the openings at the side, on the same side as the lac. Trim some openings to about half open for a small, high, sweet sound.

Hold the wot and blow across the tube openings together; the many tubes sound in harmony. Or, for a very loud sound, tie a string to the end and whirl it round. Boys usually play in groups, competing over whose wot sounds sweetest.

The wot developed from horns blown to call animals: elephant keepers hollowed a buffalo horn and blew it in rhythm, cupping it with a hand; the lead elephant knew the sound and brought the herd back to the keeper. Take care with the fire when melting lac.
