A traditional percussion instrument of the Korean people, janggu is an hourglass-shaped drum with two sound boxes linking to a slender box at the centre.
Koreans play it by shouldering its band and holding a mallet on the right hand and a stick on the left hand to beat its two sound boxes while alternating each hand with dancing movements.
With the passage of time its beating has remarkably been diversified, thus taking the podium of small orchestra or being performed independently.
Tracing its history back to the period of Koguryo, it was first called yogo in the meaning that it was put on the waist.
In the periods of Koryo and feudal Joson dynasty, it was remodelled similar to the present shape to be called thus.
Its making is based on a traditional method the Koreans have created and developed by dint of rich experience and knowledge gained through their diligent working life.
It consists of sound boxes and drumheads.
The 15 to 20-year-old paulownia is the most suitable material for sound boxes. Drumheads are made with roe deerskin.
It is made through such processes as making sound boxes, putting drumheads on the sound boxes and assembling.
Janggu-making technique has been inscribed on the list of national intangible cultural heritage.
