For the first time the given problem is considered from the point of the view of the creative orientations which have defined the development of the Ukrainian songs in the end of the ХІХth - the beginning of the ХХth centuries. It is a combination of literary and folk song's principles of creativity, that has found its reflection in the genre updating and the variety, in the transformed forms of the Ukrainian song's poetics, in the changes of the art means. The reasons and the factors of formation of the important role of the Ukrainian songs in the making of national self-consciousness are explained, that always induced to its active research the most outstanding scientists, figures of art and culture.

At the same time is emphasized, that modern song arises in complex dialectic unity of traditional and new, of the display of collective experience in individual creativity to be able again to return in the people, in the preservation of authorship and anonymous functioning.
