This section covers the theoretical and scientific aspect of this rāgam. Jhalavarali's notes when shifted using Graha bhedam, yields no other melakarta rāgam, like all 6 rāgams in the Rishi chakra (Salagam, Jalarnavam, Navaneetam, Pavani and Raghupriya being the other 5). Only these rāgams have a gap of 3 notes anywhere in their scale, between G1|to M2. Such a gap does not occur in any other melakarta by definition. Notes
