Slightly smaller than its close instrument relative, the junggeum, the dangjoek is of Chinese origin.

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.

[1] Remodeled to enhance range, it is made of yellow bamboo or sick bamboo, and possesses a single end-blowing notch, 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.
