This paper focuses on the epic music of the eastern and western regions of the Mongolian ethnic group, selecting the Mangasin Ulger from the eastern Horqin region and the Khan Harangui from the western Oirat region as case studies. It analyzes the use, artistic characteristics, and cultural connotations of the Tsoor Khuur and the Tovshur in epic performances. By comparing the two instruments in terms of their accompaniment functions, performance techniques, and symbolic meanings, the paper reveals how regional and cultural differences influence the musical style of Mongolian epics.
