The sanjo gayageum is believed to have evolved in the 19th century with the emergence of sanjo music, which literally means "scattered melodies", a musical form that involves fast tempos and some improvisation.
It is a musical instrument that is plucked with fingers by tying 12 strings made of silk thread to a paulownia barrel. Among the expression instruments used in Korean traditional music, it is the most recognized along with the geomungo, and it is relatively easy to learn and has a variety of playing methods, so it is popular.
The sound of the geomungo is firm and gentle, but the sound of the gayageum is soft, emotional, and beautiful. It is one of the most loved musical instruments in Korea.

The basic structure of gayageum
Twelve ropes twisted with silk thread are tied to the narrow and long gongmyeongdong of paulownia tree, and the thickness of the rope gradually becomes thinner.
Nonghyeon: Corresponds to the vibrato of Western music. The symbol is a wave pattern. Depending on whether nonghyeon is thick or thin, fast or slow, the thickness and frequency of the waves change. The symbols are very intuitive. Shake the strings with your left hand to modulate the sound.
