The article analyses the compositional structure in the Yhekh algys blessings in the prerevolutionary, Soviet, and modern periods. The traditional ancient festival Yhekh (Yak. ыhыах), dedicated to communication with the Upper deities, has survived in its archaic form to our times and remains the main factor of uniting the Sakha people and expressing them as an ethnos. The festival traditionally represents a complex of rites and rituals, the centrepiece of which is the algys (blessing) ceremony, which, as a separate folklore genre, has its own peculiarities. At the present stage of development of Siberian folkloristics, despite the efforts of researchers from the national republics, the genres of ritual and shamanic poetry, which arouse the interest of specialists of different directions, remain insufficiently studied. The choice of the research topic and statement of the problem was conditioned by this circumstance. The necessity of comparative and comparative consideration of Yhekh's algys on the basis of data predetermines the relevance of the work. Depending on the nature of the study, descriptive, structural-typological, lexico-semantic and linguistic methods of research were used. The study notes that the process of cultural transmission expressed in the intergenerational transmission of practices of ritual ceremonies of algys blessing is successful, which is reflected in the preservation of the main genre features and elements characteristic of traditional Yakut algys.
