In this article, synthetics is considered as an essential characteristic of ballet, which combines dance, literature, music and paining. Based on the achievements of renowned choreography theorists like J.J. Noverre, P.M. Karp, V.V. Vanslov, the authors structure the article chronologically and by heading in order to study in more detail the results of the interaction of dance with each of the listed types of arts. The main postulate of the synthetic union of various types of art with dance is their submission to choreography, its features and laws of formation. Therefore, literature, music and visual art appear in the ballet performance in changed forms: on the one hand, adapting to the needs of a choreographic art, on the other, introducing new things from their own environment.
