Yi people
Most of the above are traditional compositions dating to the Qing Dynasty or early 20th century, new pieces however are constantly being composed, and most of them follow a more Western structure. Examples of popular modern works composed after the 1950s are "Dance of the Yi People" and "Heroic Little Sisters of the Grassland" (草原英雄小姐妹). Non-traditional themes may be used in these new compositions and some may reflect the political landscape and demands at the time of composition, for example "Dance of the Yi People" which is based on traditional melodies of the Yi people, may be seen as part of the drive for national unity, while "Heroic Little Sisters of the Grassland" extols the virtue of those who served as model of exemplary behaviour in the People's commune.
