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.
