Each season, contestants are chosen from thousands of talented singers across the country and around the world, and the finalists are trained for their performances on the show. "Saptha" means seven, and "swarangal" means notes in Tamil, which refers to the basic notes of classical Indian music training: Sa Re Ga Ma Pa Da Ni Sa. Every week, a guest celebrity judge is featured, as they bring their star power, critiques, and talent to the show. Sapthaswarangal has served as a platform for introducing hot new playback singers for Indian films of several languages.
