Heejo Kim (1920-2001) is one of the most prominent Korean composers of the twentieth century. He is primarily known for his works that incorporate aspects of traditional Korean music. However, at the same time, his efforts in choral arrangements, especially of Korean folk tunes are highly acclaimed by professional choirs and conductors. The purpose of this study is to provide performance guidance on Heejo Kim's choral work, Bat-no-rae, by presenting his biographical background, discussing the use of traditional Korean rhythmic patterns (Jangdan) and modes, and the appropriate application of traditional ornamentations.

This thesis examines Yoon-Seong Cho's critically acclaimed recording Jazz Korea, in which Cho unites Korean folk music and American jazz into a single form of expression. By reinterpreting Korean folk music through jazz, Cho stimulated interest in the Korean jazz scene and a renewed interest in Korean traditional folk songs. The goal of the thesis, the first musicological essay about Yoon-Seong Cho, is to understand how Cho's diasporic experiences affected his music by leading to a process of self-discovery that allowed Cho to interpret his own identity. Through musical analysis, the study proposes a cultural interpretation of two of Cho's pieces that have achieved popularity not only among Koreans but also internationally: "Arirang" and Han-O-Baek-Nyun.
