Abhinaya is a term used in Indian classical dance and theater that refers to the art of expression. It encompasses various techniques that dancers and actors use to convey emotions, stories, and characters through facial expressions, gestures, and body movements. Abhinaya is essential for bringing life to performances, allowing the audience to connect with the narrative. There are four main types of Abhinaya: Angika (body movements), Vachika (verbal expression), Aharya (costume and makeup), and Sattvika (internal emotions). Each type plays a crucial role in enhancing the overall performance, making it a vital aspect of traditional Indian performing arts.
