The Sound of the Prairie Land (Caoyuan Zhige) for viola and piano by the Chinese composer Qingwu Guan (b. 1938) has become one of the most popular works in the growing Chinese repertoire for viola. It also exists in another version for viola and viola ensemble, arranged by the Chinese violist Wing Ho, who also expanded the viola part with the composer's approval. The pentatonic work was highly influenced by the landscape and music of Inner Mongolia, a province of China next to the Mongolian border, and incorporates the music of an ode by the Inner Mongolian composer Alatengaole (1942–2011) called Sincere Wishes for a Long Life to Chairman Mao. Guan remains a strong supporter of Mao, the first chairman of the Chinese Communist Party. The work makes use of some performance techniques of the Inner Mongolian two-stringed fiddle called morin khuur, which has a similar tone to the viola: three kinds of slides, grace notes, imitations of a horse's neigh, and the representation of horses galloping across the prairie. The background of the work, understanding of the musical structure, and information about morin khuur techniques presented in this dissertation should aid performers in interpreting the work more authentically.
