The choral music of Hyo-won Woo, the composer of Oh! KOREA, is being widely performed by universities and professional choruses in Korea, as well as throughout the world. The work exhibits Woo's remarkable compositional style, which displays traditional Korean musical influences. Hyo-Won Woo's Oh! KOREA consisting of four movements, is for chorus, two pianos, and both Eastern and Western percussion instruments. Woo's Oh! KOREA employs an excellent introduction to the Korean choral repertoire for Western audiences, rooted in traditional Korean folk tunes. As today's choral conductors, singers, and audience cannot fully appreciate the value of this traditional Korean work and will likely not understand its intended context, it is therefore necessary to provide an in-depth investigation of this work for any conductor considering a performance of this piece. This study includes influences of traditional Korean elements within Oh! KOREA and rehearsal and performance consideration for Western choir directors.

Young Ja Lee (b. 1931) is regarded as one of the most important living female composers in Korea. She leads and contributes to the Korean classical music society as a gifted composer and a dedicated educator. This study focuses on how she has combined Western compositional techniques with elements of Eastern traditional music in some of her compositions, in particular, her Variations pour piano "Umma ya, Nuna ya." An interpretation of her Variations pour piano "Umma ya, Nuna ya" reveals that the composition features many of the particular and sublime aspects of Western compositional techniques in conjunction with traditional Korean music style. This study is an investigation of the interaction and assimilation of these disparate elements. The results of this study may inspire further research into traditional Korean music and bring recognition to important Korean composers, as well as encourage music educators to teach Korean composers' compositions.
