The Tibetan polyphonic folk songs of Rewugou,situated in the upper reaches of the Minjiang River,are distinguishable into four distinct categories:ceremonial,lyrical,dance,and narrative.These classifications,alongside specific musical terminologies,reflect the structured heritage and profound root-seeking consciousness of the Tibetan community in this region.The singing techniques employed by the Tibetans of Rewugou predominantly consist of"nie(e)ie kwo nu"(a forceful,gradual ascent)and"tsə kwo nu"(a gentle,gradual ascent).A stable lineage of singing families,coupled with the generational association known as"Luta and luşa,"form the backbone of the folk songs'enduring legacy.The thematic content of these polyphonic songs,centered on warding off evil and invoking blessings,embodies the sacrosanct nature of Tibetan vocal traditions.Moreover,the transition from purely oral transmission to a blend of oral and notated practices signifies an evolving paradigm in the safeguarding of Tibetan polyphonic folk music.
