I'd always found an uncanny similarity between Shuddha Dhanyasi and Nattai. The sadharana gandharam in the former, when rendered in certain ways sounded to me like the shatshruthi rishabham of Nattai. Totally unrelatedly (or so I thought), some 10 years ago I discovered this lovely raga called Shrothaswini, thanks to a film song. I learnt that it was Shuddha Dhanyasi, but with kakali nishadham instead of the kaishiki. And then sometime last year I found this absolute gem: www.youtube.com/watch?v=KpUJtEgBS6k Prof SR Janakiraman explains so wonderfully the connection between Shuddha Dhanyasi, Shrotaswini, and Nattai. (And the way he holds the kakali nishadham - "nishcahlam" - is something to die for.) Shrothaswini is even more similar to Nattai than is Shuddha Dhanyasi coz of the former's kakali nishadham! And I also learnt from this video that Shrotaswini is probably just a fancy, new name for an old raga - Dikshitar's own - Udayaravichandrika. (Prof SRJ does not use the name Shrotaswini at all.) Up until this I'd thought that Udayaravichandrika was the same as Shuddha Dhanyasi. I think this is in fact the popular opinion, which Prof SRJ challenges.
Anyway, I was obsessing about this Udayaravichandrika/ Shrothaswini - Nattai connection over the last few days and couldn't help but record this small piece. Hope you like it.
