The manual is devoted to the study of theoretical aspects of the avant-garde text. The author's focus is on the problem of "morphology" of the text and the latest research strategies for analyzing the heritage of the artistic avant-garde of the 1910-1925s. twentieth century. The subject of research is a formal experiment in painting, poetry and theater, in which the foundations of the latest performative practices are laid. In the context of the radical transformation of previous cultural values ​ ​ and the recoding of classical patterns, it seems natural to the author that the origins of a new anthropological and linguistic turn should be sought in the formalization of Russian avant-garde artists.
