There was a song that threaded through Arun’s childhood: a low, peculiar melody hummed by the men who mended nets and the women who rubbed turmeric into each other’s palms. They called it an isai—music that was not just sound but a way of remembering. When he was small, he imagined the notes had the power to call water from the earth and lull the snakes to sleep. As he grew, he found that music kept other things quiet as well—anger, shame, the questions people were too afraid to ask.
