The basic structure of the flute

After drying in the shade, the bamboo used in the flute basically needs to go through processes such as cutting, painting, drilling, tuning, winding, and engraving. One of the distinctive features of flutes is that they are often engraved with Tang poetry and the name of the maker. The bamboo flute is made of a bamboo tube. The inside is hollowed out to form an inner chamber, and the outside is cylindrical. There are 1 blowing hole, 1 membrane hole, 6 sound holes, 2 fundamental sound holes and 2 Auxiliary sound hole.

The body of the flute is made of a bamboo tube with sections removed and hollowed out to form an inner chamber.

Flute stopper: a stopper made of soft wood, installed at a certain depth in the tube at the upper end of the blow hole.

Flute film: It is usually made of reed film. After rubbing it, take a small square and use it. After the air flow vibrates the flute membrane, it can produce a crisp and bright sound.

Flute holes: divided into blowing holes, membrane holes and sound holes.

Sea bottom: Also known as the flute head, it is a section of the inner chamber of the flute body from the inner edge of the flute plug to the center of the blow hole. It prevents the air from flowing upward, allowing the mouth wind to flow downward and concentrate the pronunciation.

Silk strings: Use silk strings to wrap around the outside of the flute body. There are 21 to 24 strings in total, which protect the flute body from bursting.

Floating fringe: an ornament tied to the sound hole, usually made of ribbons.

Inlay: Usually the left end (or both ends) of the flute body is inlaid with ox bone or ivory, which is called the inlay.
