This paper examines , known as the Hamgyeong-do folk song and new folk song(新民謠), analyzing and reviewing its spatial and genre identity. As it is well known, is music set in modern cities on the east coast, which developed rapidly with the opening of ports and railway construction in the 20th century. As the song was spread more widely among the general public, it appears that people started to perceive as having the identity of a Hamgyeong-do folk song and new folk song. However, based on the synthesized materials on folk songs currently available, it was found that the distribution of in Hamgyeong-do was relatively small and limited to the southern area adjacent to Gangwon-do, while having larger and more significant distribution in Hwanghae-do and Gangwon-do, where was enjoyed more actively. This raises doubts about the previously established spatial identity of linked with Hamgyeong-do. In addition, was found to bear marks of having been accumulated over an expanded period, unlike how other new folk songs that were accepted as part of folk songs. Therefore, it suggests the need to reconsider the classification of as a new folk song so far. Based on these examinations, this paper seeks to suggest the new spatial and genre identity of based on its lyrics and musical analysis available from various sources. First, it was discovered that has a distinct feature of borrowing lyrics from class and class of songs, both belonging to Hwanghae-do Seon-sori(立唱). Additionally, this paper examines temporary changes in the rhythmic type and the emergence of Nae-deu-reum (a special introductory melody) in , which are characteristic of Seon-sori music. Changes in the range and motion of melody are investigated as well, related to the aforementioned characteristics of , distinguishing itself from existing forms of Menaritori. Finally, this paper establishes that the Sadangpae-sori(wandering artist group's music in traditional society) is an old form or a transformation of through analysis and comparison. Based on the analysis to be elucidated, it is concluded that is a Seon-sori type of music with its musical origin found in Sadangpae-sori in Hwanghae-do. This paper seeks to address the aforementioned doubtful points through this modification of into a Seon-sori type of music. The main distribution area of coincides with the major activity areas of the Hwanghae-do Sadangpae. It also becomes possible to explain the marks left in this song due to temporal accumulation as it was accepted earlier as part of folk songs, with the way it was spread to Sadangpae-sori in pre-modern times. In the 20th century, artists created songs reflecting the changing times and sentiments of city dwellers. In this context, was chosen by them as a song set in a modern city adjacent to the east coast. Hwanghae-do Seon-sori-pae sang lyrics with modern and urban themes based on their previous repertoire, Sadangpae-sori . It is guessed that the recognition of as a Hamgyeong-do folk song and a new folk song has formed in this context, with its another name, . However, based on this paper’s investigation, it seems more appropriate to understand as belonging to Hwanghae-do's Sadangpae-sori.
