In this essay, the author is presenting and explaining elements of music art found in Kostić's literary work, such as poems, ballads and dramas. It argues that he depicted singing and dancing as part of the desired atmosphere symbolic of the crossover of music art into the natural phenomena and used technical music expressions in his poetic narrative. The basic goal of the paper is to determine and classify music elements in Laza Kostić's literary discourse, i.e. the manners in which the poet has used them. The author describes the function of using musical elements as dramatizations of the poetic text and its tragedies. Using musical elements in an original way, Kostić has emphasized patriotic themes in his epic narratives, as well as romantic theme in the lyrics of songs, poems and dramas. It can be concluded that Kostić has had a great knowledge of the art of drama, and that he has used the knowledge of drama techniques throughout his literary oeuvre.
