Jana Ranjani is a raga in Carnatic music, classical music of South India. It is a janya raga of Shankarabharanam, 29th in the 72 Melakarta ragas. The Raga is named thus because it induces a feeling of enjoyment (Jana - People and Ranjani - can be enjoyed by people) among the rasikas(audience).
It is a Vakra sampoorna - Audava ragam i.e. the ascending scale has all the notes in a zig-zag manner and the descending scale has five notes. It's Arohana-Avarohana structure is as follows:
Arohana: S R2 G3 M1 P D2 P N3 S
Avarohana: S D2 P M1 R2 S
This section covers the theoretical and scientific aspect of this rāga.
Janaranjani is very similar to Poornachandrika and these Ragas are known as twin Ragas. Unless sung with perfect sangathis and pidis, it is highly difficult to differentiate between the two.
