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.

In the following chapter, the unfair treatment of popular jazz styles is examined. Many early and influential jazz critics sought to elevate jazz to the status of art music by discrediting popular jazz styles. These critics used specific criteria and emphasized notions …
