Janggu is a traditional percussion instrument created and developed through the working life of the Korean people.

Janggu, considered to have originated in Koguryo (B.C. 277-A.D. 668), was called "Yogo" in the meaning of a drum to be put on at the waist.

It was in the periods of Koryo (918-1392) and the Feudal Joson Dynasty (1392-1910) that Janggu was remodeled similar to the present shape and called by the present name.

Janggu is an hourglass-shaped drum with two sound boxes, two batter heads and tension ropes. Its manufacturing is completed through such processes as making sound boxes, putting batter heads on the sound boxes and assembling.

Janggu is widely known to the world for its peculiar, deep and full sound.
