The ajaeng is a Korean string instrument. It is a wide zither with strings of twisted silk. It is played with a slender stick of forsythia wood that is drawn across the strings in the manner of a bow. The ajaeng mainly plays the bass part in ensemble music. And the ajaeng is divided into two types. The ajaeng used in court music is called jeongak ajaeng, and the ajaeng used in folk music is called sanjo ajaeng. The original version of the instrument, and that used in court music, has seven strings; while the ajaeng used for sanjo and sinawi has eight. Some instruments have as many as nine to twelve strings.similar to the koto but bowed
