In the world of theater and literature, characters and dialogues play a crucial role in conveying the message and themes of a play. Mikhail Bakhtin's theories of monophony and polyphony provide powerful tools for analyzing and gaining a deeper understanding of these elements. Monophony refers to the dominant, unilateral voice of the author, where the voices and perspectives of other characters are marginalized. In contrast, polyphony emphasizes the diversity and plurality of viewpoints and voices within the text. While these theories have been predominantly applied in the analysis of novels and fictional works, their application in the context of plays, particularly contemporary Iranian plays, has received less attention. The play "Whispered Tales, " written by Amir Reza Koohestani, is an ideal example for examining the theory of polyphony, given its dialogue-driven nature. This work, due to its creative use of dialogues and interactions among characters, provides a suitable ground for polyphonic analysis. Therefore, the main question of this research is how Bakhtin's theory of polyphony can contribute to a better understanding of the narrative and semantic structure of this play. This study aims to clarify this issue by analyzing the play and demonstrating how this theory can serve as a tool for analyzing and critiquing contemporary plays in Iran and beyond, as well as how it can enhance the performance and understanding of the work.
