The origin of Gayageumsanjo was started by Kim Chang-jo (1865-1919), a native of Yeongam, South Jeolla Province, in the late Joseon Dynasty. Starting with the slow Jinyangjo rhythm, Jungmori, Jungjungmori, and Jajinmori rhythms became faster and faster. It is one of Korea's representative instrumental solo genres, using various groups such as Ujo, Pyeongjo, Gyemyunjo, Gyeongdreum, and Gangsanje. The beauty of the melody, which has a free melody in a certain frame and draws the emotions of the performer by repeating the tension and relaxation, is indeed enough to express the emotions of traditional Korean music.
The transfer of various factions, including Jeongnamhui, Choeoksamryu, Gangtae Hongryu, Kim Byeongho and Kim Jukpa, is taking place. In 1968, Gayageum Sanjo and Byeongchang were designated as important Intangible Cultural assets, and other factions were well-suited as the holder. However, Kim Byeong-ho's Gayageum Sanjo is considered to have the deepest taste in Nong-hyeon, but it has not been designated as an Intangible Cultural asset. Kim Byeong-ho was born in Yeongam, South Jeolla Province, in the same region as Kim Chang-jo, the founder of the Gaya Geumsanjo, and his Sanjo is rooted in Kim Chang-jo. Since then, Kim Byeong-ho created his own Yupa, which has a wide range of sounds and a deep taste, and his Yupa has a more unique beauty by using the Umori rhythm, which is not found in other yu. Fortunately, he was transferred by Kang Moon-deuk and Yang Yeon-seop, who were taught by Kim Byung-ho, and Kim Nam-soon and Sun Young-sook are passed down to Kang. Yang Yeon-seop, who also learned from Kim Byung-ho, is training junior students in the academic world, mainly in Seoul. Kim Nam-soon is active in the Yeongnam region, and the transfer is taking place in the Jeollanam-do region, with Sun Young-sook at the center.
Kim Chang-jo, the founder of the Gaya Geumsanjo, was born in Yeongam, South Jeolla Province, and Kim Byeong-ho, who learned from him, is also from Yeongam and needs to be designated as an Intangible Cultural asset of South Jeolla Province based on his regional background. Since entering Gayageumsanjo in the 1960s, Seon Yeong-suk has been fully transferred from Kang Mun-deuk to Kim Byeongho-ryu Gayageumsanjo, and won the Grand Prize (President's Award) in the string section of the National Traditional Music Festival in recognition of his skills. Therefore, Seon Yeong-suk, who designated Kim Byeong-ho-ryu Gayageum Sanjo as an Intangible Cultural asset of Jeollanam-do and faithfully carried on his production, needs to be recognized as the owner of Kim Byeong-ho Sanjo and preserved.
