On listening, this raga gives a feel of another Rare, but popular raga, ‘Kathanakuthuhalam’; though there is no much similarity in notes, both are of same origin, Sankarabharanam mela; also both are of zig-zag arrangement of notes. It is likely that Ramanathapuram Srinivasa Iyengar was inspired by his guru, Patnam Subramanya iyer (created Kathanakuthuhalam) in creating this raga. Surprisingly, in one of the publications, the author of the krithi, ‘Raghunatha nannu’ is wrongly attributed to Patnam Subramanya Iyer and in another, as Mysore Doraisamy Iyengar !
