What are the Korean traditional music?

Traditional music, as the name suggests, is music that retains the old Korean beats. Sometimes it also refers to Korean traditional music. During the Three Kingdoms Period (57B.C.-A.D.676), Korea had already produced classical musical instruments such as Goguryeo's Xuanqin (similar to the guzheng) and Gayagea's Gayageum. Cultural exchanges with China and Western countries also introduced foreign music. Introduced to Korea. Entering the Goryeo Dynasty, elegant music and folk music became active. Gagaku, or elegant music, evolved from Dasheng music from China. It is the palace music played during ancestral temple ceremonies; hyangak is the music inherited from the Goguryeo, Baekje, and Silla eras to the Goryeo era. Refers to Korean traditional ritual music that is different from Gagak and Tanggak. In the Joseon Dynasty (1392-1910), the early and middle stages of music were represented by palace music, and later by folk music. Yayue, which belongs to palace music, is related to the etiquette and customs in the palace. It is more often played at banquets for entertaining state guests and is mainly about praising the royal family. By the 15th century, the music theory work "Music Studies Standards", which concentrated on music theory, history, and playing musical instruments, was compiled and published. In the late Joseon Dynasty, with the improvement of agricultural productivity and the development of industry and commerce, citizen culture developed greatly. In the field of music, the class that enjoys music has expanded, and music forms have diversified, especially the emergence of a cappella (pansori) and folk songs created by citizens. Folk music truly expressed the feelings of the people at that time and satirically criticized social injustice. This kind of folk music developed later and appeared in new forms such as four-object performances, which was deeply loved by people. Siwu performance refers to percussion played with four instruments: gong, zheng (similar to a gong, but with a lower sound), janggu (drum that can be struck on both sides) and drum. There are more than 100 kinds of musical instruments used in traditional music. According to different playing methods, they are divided into three types: string instruments played by plucking strings, wind instruments played by mouth, and percussion instruments played by blowing. Stringed instruments: gayageum, hyongeum, dulcimer (a quadrangular board hyongeum, called dulcimer because it was introduced from the West), erhu, Yazheng (a seven-string zither, the bass instrument with the narrowest range among string instruments) and other wind instruments: Big flute, small flute, flute, short flute, peace flute, sheng reed, trumpet, screw horn, hole flute and other percussion instruments: beat (also called clapper, similar to allegro, but the number of wooden boards is 6), chimes, chimes, waist drums , gongs, drums, etc.
