Seodo-sori refers to folk songs and japga, which were handed down in Hwanghae-do and Pyeongan-do provinces (Seo-do areas), and the exact timing of when the song began to be sung is unknown.
Seodo-sori is composed of Pyeongan-do folk songs, Hwanghae-do folk songs, Seodo japga, a poem reciting Chinese poems, and Baebangi-gut, which has a dramatic composition.
In Pyeongan-do folk songs, there are water-seam-ga, woven water-seam-ga, gin-ari, jaja-ri, and Anju-ae-seong. The most famous water-seam-ga is the water-seom-ga, which recited the sorrow as a complaint when the people of Seodo-gun were blocked from public office since the early Joseon Dynasty.
Pyeongan-do's sound generally consists of five notes: re, mi, sol, la, and do, which form the framework of melody by going down a full five degrees from the shaking sound 'la'. In general, the editorial is long and the rhythm is not constant, so it is characterized by proper arrangement of the editorial.
In the folk songs of Hwanghae-do, there are Ginnanbongga, Jajeonnbongga, Byeongsinnanbongga, private Nanbongga, Sanyeombul, Jajinyeombul, and Monggeumpotaryeong, which are famous for their nangbongga and wildfires.
The sound of Hwanghae-do represents the general melody of Seodo, along with the sound of Pyeongan-do, but it is slightly different in terms of its melody progress. Pyeongan-do also has a certain rhythm compared to folk songs, and is bright and lyrical.
Seodo japga is a sit-down sound that opposes the introduction of Seodo, and there are Gongmyeongga, private Gongmyeongga, Chohanga, Jejeon, and Chupung Gambyeolgok, among which Gongmyeongga is famous. Seodojapga has a long editorial, and the rhythm is irregular according to the embroidery of the song. There is something in common that ends with a deep-seated attitude when closing the end.
The rhythms of Seodo sound, commonly called "Sushimgatori," are usually played from the top, the top notes are dropped, the middle notes are shaking violently, and the bottom notes are stretched straight, making it sad to sing these sounds in a relaxed.
The singing style of Seodo Sori is a bit unique, but since there are Sokcheong and Bongcheong, Sokcheong uses a sound that is pulled with the inner voice and the head and the back of the main office.
Baebangi Gut is a music that is often compared to pansori in Namdo, and a singer narrates Baebangi's story in a humorous way by mixing folk songs, radish songs, and jaedam based on Seodo's basic musical grammar in line with Janggu's accompaniment.
Seodo-sori is a sound that has been handed down by the people of Seodo, who have been living in a harsh climate adjacent to the continent, along with the northern immigrants, and their living emotions are also well reflected in the songs.
