Gayageum sanjo refers to a sanjo designed to be played with gayageum. Sanjo refers to the form of playing a musical instrument alone, starting with a slow rhythm and gradually turning into a fast one, which slowly makes the listener nervous and excited.

Gayageum Sanjo is composed of four to six rhythms. Looking at the feelings of each rhythm, Jinyangjo is very slow and lyrical, Jungmori is stable, and Jungjungmori is very entertaining. Self-momori is bright and cheerful, and Hwimori has excitement and urgency. It was made before Sanjo played with other instruments, and due to its outstanding technique, it attracted a lot of people's attention and formed several factions.

The characteristics of the new type Gayageum Sanjo are that Jangdan Guseong is located between Gutgeori and Jajinmori, and unlike other mountains, Jinyangjo begins as a surfactant, and carp hangers are frequently produced and attached in Jangdan. In addition, Jungmori rhythm has a long surfactant melody and is characterized by an offmori following the Danmori at the very end.

Kang Soon-young, the artistic owner of Gayageum Sanjo, has a 30-minute-long body and is well-represented. Kang Soon-young is 75 years old and has not lost her strength, so her voice is deep and delicious.

The Gaya Geumsanjo of the Neogwanyongryu Hermitage is well worth preserving and has been active in the Jinju area for 36 years.
