In this study, Kim Chong-gi, who stood out in various fields of traditional music during the Japanese colonial period, reviewed the situation of performing arts activities at the time. First, the contents related to Kim Chong-gi investigated by Lee Bo-hyeong were reviewed again, and Kim Chong-gi's stage activities, gramophone recordings, and activities appearing on JODK broadcasting stations were re-examined and supplemented. Looking at the contents of Lee Bo-hyeong's research, it was found that reinvestigation was necessary in Kim Chong-gi's year of birth, kŏmun’go sanjo teacher, activity base, and genealogy of transmission. It is possible that his year of birth was before 1904 or 5 years, and the teacher of kŏmun’go sanjo was thought to be more likely not Paek Nak-chun but Cho Sang-sŏn who worked with him. It was necessary to investigate the process of moving from Chinju to Seoul and check various other contents. In the case of performing arts stage activities, it was found that performances were mainly hosted by gramophone record companies and sponsored by newspapers during the Japanese colonial period. The first performance was “All Chosŏn Master Singer Contest” hosted by Nipponophone Co. for three days from November 21, 1928 and sponsored by Chosŏn Ilbo, and the next was a “Charity Entertainment Contest” hosted by Okeh Records Co. and sponsored by Chosŏn Ilbo over two days on December 23 and 24, 1933. The “Charity Entertainment Contest” continued with tours in Taegu, Pusan, P'yŏngyang, and Kaesŏng. And next, it seems that he appeared in “The Night of Music and Talk”, the first anniversary performance of the magazine Chungang, but data on the actual appearance could not be secured. Kim Chong-gi recorded 2 records 4 sides at Nipponophone Co. and Nippon Columbia Co. during the Japanese colonial period, and recorded 58 records 132 sides at Okeh Records Co. Considering the re-release, the number of gramophone records he recorded is 58 records, all of which correspond to 136 sides. He introduced music in various fields, including sanjo and pyŏngch'ang and vocal accompaniment for kayagŭm, sanjo and period drama accompaniment for kŏmun’go, new pansori and folk song accompaniment for haegŭm, and period drama accompaniment for tanso. The broadcast on JODK showed a new side of Kim Chong-gi. From 1928 to 1929, Kim Chong-gi appeared in ch’anggŭk, a play based on pansori, while appearing 11 times from 1928 to 1929, revealing himself as a master pansori singer. In 1930, he appeared as a master singer of Kim chŏng-mun only once, and from February to December 1934, he appeared steadily 27 times, singing or playing kayagŭm in namdo tan’ga, riyo, kayagŭm pyŏngch’ang, namdo chapka and Farmers Song, ch’anggŭk-cho, kayagŭm sanjo and pyŏngch'ang, and Poongnyeon Dance.
