Zagor is a ritual musical theater form of Goa. It is celebrated by the Gavdas of Tiswadi and Ponda. It is a night long performance to commemorate and worship village deities. Zagor performances begin with the Nomon, which means to bow. This invocation is sung for Shankar Bhagwan—God of regeneration. The final section of the nomon is to Goddess Sateri, who is an aspect of Shakti.
