Tang epoch trains (618–907) – an important source of judgments about expressive possibilities and sound archetypes of the Chinese flute, preserved in the music of the Celestial Empire composers of the XX – XXI centuries. The purpose of this investigation is to establish sound archetypes of the flute in the Chinese poetry of the Tang epoch. The methods of investigation are historical, semantic, genre and comparative approaches. The scientific novelty of the study is to introduce the concept of «flute poetry» of the Tang era into the musicology context, to establish its characteristic properties (spiritualization of the desolate time space with a magic melody, the reflection of the state of the soul of a lonely hero, the presence of the image of the listener-poet, connection with the elements of the wind, the nocturonal semantics of the natural landscape, signs of the palace style, the embodiment in the sounds of the flute - the mediator between the earthly and celestial worlds – philosophical ideas), the formation of the thesaurus of flute affects (moaning, sadness, sadness, state of waiting, experiencing loneliness). The samples of «flute poetry» by Li Bo, Du Fu, Wang Wei, Zhao Gu are considered. The image of the jade flute from Li Bo's poem symbolizes the priceless in human life. In Li Bo's poem about the Qiang Maiden, the flute music takes on the meaning of a leitmotif that accompanies the drama of love and separation. In Du Fu's work, the limits of earthly time and space contrast with the boundless celestial chronotope associated with the flute's sound image. In Wang Wei's poetry, the flute's crying accompanies the suffering of an abandoned woman and finds a response in the soul of a lonely traveler. Zhao Gu's poem includes the names of mythical flute artists Huan Tzu and Ma Rong, contributing to the sacralization of time and space in the work. Conclusions. In «flute poetry» of the Tang era, there are typical features of a common creative method inherent to the masters of the word «golden age»: the sound image of the flute is inscribed in a common artistic continuum based on the reflection of the poet's surrounding nature in a lyrical-philosophical landscape.
