This is the summary of thesis of a geomun'go(거문고) musician Ok-bogo's(玉寶高) history and work. Keomun'go, a Korean zither with six-string, is one of the oldest string instruments in Korea. It belongs to the family of long zither with movable bridges. The instrument has some characteristics in terms of structure : it has sixteen fixed frets and three movable bridges ; it has six strings, three of them are stretched over sixteen bridges, the other strings are over the bridges. These strings are plucked with a suldae(술대), a slim bamboo stick. Two of them play tune and the other strings play drone. While known as geomun'go, this instrument has been called as hyeun'gum(玄琴), meaning a Koguryeo(高句麗) string instrument, in Sino-Korean. Ok-bogo was a musician who researched new playing method of geomun'go in Silla(新羅) dynasty (about in the 9th century). He had studied new playing method of geomun'go in Unsangwon(雲上院) of Mt. Jiri(智異山) for fifty years. Based on literatures and reasoning, those make me have the confidences to come to the conclusions, as follows. Firstly, Unsangwon is Unbong(雲峰) of Namwon(南原) county in Jollabukdo(全 羅北道) province, and Keumsongjeong(琴松亭) was a pavilion, where he teached geomun'go to his scholar Sok-myongdeuk(續命得) in. Secondly, two new playing methods of geomun'go, Pyeong-jo(平 調) and U-jo(羽調), was originated by him. Finaly, some of his works were related to Buddhism and Mr. Jiri.
