The gayageum means a stringed instrument (geum) of Gaya, an ancient country located in the southern part of the Korean peninsula. According to the History of Three Kingdoms, King Gasil of the Gaya dynasty created the gayageum based on a Chinese instrument. The body of the gayageum is made of a long paulownia. The instrument has twelve strings placed on movable bridges. The right hand makes the sound and the left hand makes the tunes. There are two kinds of gayageum; one used for classical music and the other used for folk music.
