This study examines the significance of Korean performing arts history by focusing on the Little Angels’ organizations and management, the composition of the repertoires, and the meaning of international performing arts history. As a semi-professional organization, the Little Angels developed and operated the member selection musician system, and toured through overseas professional management in the early days. The repertoires of the Little Angels, including Korean traditional dance, music, and choral music were staged, established and systematized as the standard repertoires during the early activities of the cultural mission. Little Angels' dance was developed to be suitable for the children's group dances and the overseas staging of the new dance, and the choral repertoire, which included Korean folk songs and world folk songs played a major role in public diplomacy. As the only 'folk art troupe' among children's art troupes active in the international performing arts world, the Little Angels helped introduce Korean performing arts to the international audiences. Through the study of the Little Angels, a children's art troupe as well as a private art troupe with a 60-year history of international activities, this paper encompassed the history of Korean contemporary performing arts in a rich and stereoscopic way.
