It is a janya rāgam (derived scale), as it does not have all the seven swaras (musical notes).
This scale is known as Shuddha Sāveri in the Muthuswami Dikshitar school of music.
Karnataka Shuddha Saveri is a symmetric rāgam that does not contain gandharam or nishādam.
It is a symmetric pentatonic scale (audava-audava ragam[1][2] in Carnatic music classification - audava meaning 'of 5').
Karnataka Shuddha Saveri's notes when shifted using Graha bhedam, yields 1 popular pentatonic rāgam, Amritavarshini.
