The relevance of the research consists in the identification of the fundamental laws of text creating. The belle-lettres text is considered to be a structurally organized form of information with the aim of rendering esthetic impact on the recipient. The general structural principles of the text (integrity and regularity) are characterized by such properties as proportion, harmony, symmetry and rhythm. Rhythm as regular alternation of signs of different language levels organizes, both the structure of the text, and a process of conveying information by the sender and its perception by the recipient. Rhythm is one of the mechanisms to realize the functional and semantic category of expressivity. The hierarchy of meanings reached as a result of rhythmic orderliness of the text creates esthetic effect and provides sense increment. The author discriminates two kinds of syntactic rhythm: assimilative rhythm for transmission of factual information and dissimilative rhythm as means of rendering esthetic information and realizing the author's intentions. Subjected to analysis is dissimilative rhythm with the aim of identifying the reasons for functional failure of assimilative rhythm.
The research is carried out in accord with the main principles of communicative and paradigmatic linguistics. It is devoted to the study of lingual ways of expressing harmony as an ethetic category. Rhythm as a regular repetition of similar and commensurable units of language is considered to be the main mechanism of the harmonious organization of belle-lettres style texts. The high efficiency of rhythm as a stylistic device creates the expressiveness of the text at all the levels of language, beginning with the phonemic level and finishing with the dictemic level. The principle of repeatability of elements and their relations within the system of semantic and syntactic ties manifests internal symmetry; and the symmetry of text elements is the main indicator of its harmony.
