The popular musical instruments are described:
Flute or Sumui: Flute is the least mechanical of all the instruments. It is constituted of bamboo. Sumui are of two types: one has seven holes and the other has eight holes. Most of the flute has dual characteristic features: Those held along the mouth and those held across the mouth
Sumui is made of the hollow stem of a bamboo. The bamboo is cut into a suitable length and thereafter put to his lips in a playing position that determines the distances of the flute. The distance becomes the standard length and on determining the position the marked areas are burned with a hot iron nail. Finally a separate mark is scratched in alliance with the stop-hole near the upper rim. It is marked at a distance of one finger-width for a rectangular cut that is gradually sloped according to thickness of the stem. With a knife that marked area is cut.
