Tar makers transmit their skills to apprentices, often within the family. Craftsmanship begins with careful selection of materials for the instrument: mulberry wood for the body, nut wood for the neck, and pear wood for the tuning pegs. Using various tools, crafters create a hollow body in the form of a figure eight, which is then covered with the thin pericardium of an ox. The fretted neck is affixed, metal strings are added and the body is inlaid with mother-of-pearl.
