Among native Korean choral composers, Hyowon Woo has emerged as one of the most significant representatives of choral genre, both in Korea and internationally. She has created a new style of choral music that combines traditional Korean musical elements with contemporary Western compositional techniques, in a synthesis that generates new sonorities and effects. Her choral music falls into three basic categories: music employing direct quotation of Korean folk tunes or other elements, which produce typical Korean sonorities; music using Western practices, which produce modern and Western flavors; and music combining Korean traditional methods with modern Western concepts. Hyowon Woo’s unique contribution to contemporary Korean choral music is ideally represented by her Gloria, which will form the basis for this study. Because traditional Korean music culture has such a strong presence and influence on her choral compositions, detailed knowledge of these elements are essential for the study and performance of her work. The combination of traditional Korean music and Western contemporary techniques lies at the core of her compositional style, and is the principal focus of this study. A detailed understanding of these stylistic elements, both Korean and Western, and how they work together to achieve the composer’s purpose and vision, is vital to achieving an informed performance of this work.  This study is intended to supply the conductor these needed tools and to add to the small but growing body of literature related to the performance practice not only of Woo’s significant body of choral compositions, but of Korean choral music in general.

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.
