What is "dangjeok"

The dangjeok is a small transverse bamboo flute used in traditional Korean music. Slightly smaller than its close instrument relative, the junggeum, the dangjoek is of Chinese origin. Its name, derived from the Chinese Tang Dynasty, dangjeok translates to " Tang transverse bamboo flute." The dangjeok is an aerophone which gives off a clear and bright sound, and has a limited one and a half octave range according to the ancient Korean music treatise, the akhakgwebeom. It is often played accompanied by the Korean lute and xylophone. Remodeled to enhance range, it is made of yellow bamboo or sick bamboo, and possesses a single blowing hole, and seven holes to control pitch, though the seventh hole is not used. Of traditional and current instruments of Korean origin, the dangjeok has the highest pitch.
