The drum is a percussion instrument based on resonance, which was made to make a sound by filling leather in the stable of a barrel, and has been used in various ways, including folk games, spears, dances, and martial arts in shamanism, with signals of various rituals and wars. The drum consists of two main processes: leather work and drum control work. Buktong, which mainly uses Odong, Yuksong, Miseong, Pine Tree, and Bakdal Tree, has a bucket that is the same size as a barrel made by digging logs. The wood is cut into pieces to fit the length of the tree, and then dug from the core to cut through the inside to create a barrel, but it is difficult to find thick logs, so it is usually made of chunks. The sound of leather depends on the quality, thickness, and area of the animal <span class='xml2' onmouseover='up2 (3985)' onmouseout='dn2()'dn2(()> Wonpi<//span> to remove the hair or to make it into leather, with chicken dung or soybean paste.

Kim Kwan-sik has moved to Daejeon with his grandfather, who had produced the drum for more than 30 years in Chaeun-myeon, Nonsan, South Chungcheong Province, to fill the drum for the third generation after his father, who produced the drum for more than 50 years. He possesses processing techniques by conventional methods, such as screening of leather that governs drum sounds and leather processing and control works, and is a craftsman who has the ability to produce works and goods separately. The main theme of the book is "Julbuk (Wednesday Book)," "Kojangbuk" (Sijo, Pansori) and "Milyangbuk" (for shamanistic people), but it can also produce various kinds of books.

Gagok is also known as the Eternal Ring Jigok, which is a vocal piece that is included in the regular price along with sijo and lyric that were popular in the upper class society of the Joseon Dynasty. The lyric of Sijo is sung in the form of Chapter 5 to the orchestral accompaniment of Piri, Jeotdae, Gayageum, Geomungo, and Haegeum. Its artistic value is excellent compared to that of Sijo and its lyrics. Traditional songs are played by 16-night or 10-night Janggu Jangdan accompaniment, and are based on 24 songs and are divided into male, female, and male and female songs according to the classification of people.

The song originated in the early Joseon Dynasty, and the current song was formed at the end of the Joseon Dynasty. As the mandaeyeop and Jungdaeyeop gradually declined during the late Joseon Dynasty, the sagdaeyeop became more prevalent, and from the end of the 17th century, the sagdaeyeop became a variant of 1, 2, and 3. By the 18th century, Jungger, Pyeonggeo, and Duger were derived from the Great Lakes of Isu, and by the 20th century, they grew into huge vocal music like today's songs.
