Se Enkhbayar (b. 1956) is one of the most important contemporary Mongolian composers in China. His choral tone poem, Önchin Botog, integrates the traditional Mongolian musical elements Urtiin Duu (long song) and Khöömii (throat singing) with modern choral music and is one of the most representative works in the genre of modern Mongolian choral music. The purpose of this study is to provide a performance guidance for non-Mongolian musicians on Se Enkhbayar's work, Önchin Botog, by presenting his biographical and cultural backgrounds, discussing the use of traditional Mongolian singing styles, special rhythmic patterns (horse-step rhythm) and Chinese pentatonic scales. For conductors, this guide can shorten preparation time by providing musical analysis for artistic interpretation and practical points for sound effect creation. For solo singers, this guide will enable a Bel Canto singer to sing Urtiin Duu in Mongolian singing style. For Khöömii singers, this guide provides supplementary practical suggestions.
