Henglu Yao is a contemporary Chinese composer who has composed a large number of intermediate piano works using a blend of traditional Chinese musical elements and modern Western compositional techniques. This dissertation uses Yao's Mikrokosmos from Chinese Nationalities, composed in 2017, to conduct a comparative study with last three volumes of Bartók's Mikrokosmos, exploring the folk music characteristics of the two composers' respective nationalities. Furthermore, this dissertation observes the musical and technical similarities and differences in modern piano teaching repertoire, especially those that are influenced by their respective national musical traditions. The comparison and elaboration of the two composers' use of modern harmony, modern rhythms, imitation of folk instruments, and application of mathematical concepts are detailed in the text. In addition, I provide pedagogical suggestions on the challenges of practicing the contemporary music in Yao's Mikrokosmos, including aural training, asymmetrical rhythmic training, and phrasing practice. Lastly, I provide detailed suggestions for certain pedaling and fingering aspects with which students may struggle.
