Sriram Ramabhadran comments :
I really enjoyed the article. Could you please comment on the difference between Natakurinji and Ravichandrika ?
Thanks and looking forward to your next article,

The authors respond:
Both Natakurinji and Ravichandrika share a similar scale. However the treatment of the swaras, especially g and n (we adopt the same swara notation as in our article) are different.
Consider the treatment of n in these two ragas. Natakurinji uses n as a nyasa swara in prayogas such as m d n, (d)n. The nishada also occurs prominently in prayogas such as d n s", d n s" d n". This is to be contrasted with Ravichandrika where a weaker n occurs (only) in the avarohana as s" n d m.
As we pointed out in our article, g plays an important role in the development of Natakurinji but when used as a nyasa swara, it is usually in conjunction with m or with s; e.g., g - m g s, or s r g (g) m etc. Ravichandrika employs phrases such as m g - m g, s r g, d m g etc. Clearly, g plays a stronger role in this raga. Ravichandrika allows the prayoga m g r s as well.
Finally, we recall S. R. Janakiraman's remark about the special role played by the panchama in Natakurinji. It is "not within raga dharma" to eschew panchama in Natakurinji, whereas Ravichandrika skips the panchama altogether.
