The most knowledgeable experts in CM have written pages and pages on it : http://www.carnatica.net/newsletter/ara ... letter.htm
There are plenty of compositions in it....
And yet, dEvagAndhAri doesn't have its own thread till now?

Ok, getting to the point, dEvagAndhAri as a rAgA exists only because of the kind of phrasing and gamakas possible in it. The handling of the R2, the G2, the D2, the N2 and the presence of the N1 and phrases like PMD,D, -- DNS (or DSNS - gamakas allow both), SN3 DN2,DP, SRGR,GRSS, SND-RSR, and MGR-P. -- DP M,MGR, and many others, along with the brigha sets possible are the very core of the rAgA.
Despite said brighas though, the rAgA is truly at home in the slower tempo, a leisurely boat sailing in calm waters, where the gamakas can work their magic.
This time, I am going to start from a rather different place to cover the repertoire in this rAgA, mAnikkavAsagar - https://www.youtube.com/watch?v=Xy-zb5c-9Es
https://www.youtube.com/watch?v=_Yq6dvH14Jo - the tiruppAvai and tiruvempAvai set is very good for learning the essence of the rAgAs they cover
I'd like to make a confession here - dEvagAndhAri might have been the very first rAgA I ever recognized as a child, because of this kriti - https://www.youtube.com/watch?v=hpxLTKAdGkw (Only it was by Yesudas and I wore out that cassette by listening to it so many times!)
The PDND-MPDP-PDND-PMDP-PMPM-GRGR-SRSND,-R,S, is a recurring phrase throughout the song, and it stamped itself into the very identity of the rAgA with it.
Of course, Thyagaraja hasn't stopped there. Here's a full fledged rendition of seetAvara sangeeta gnyAnamu - https://www.youtube.com/watch?v=h8Np6LKwgPc - by the one and only MMI.
And then there's karuNA samudra - https://www.youtube.com/watch?v=BO3wGVYYKf8 - by LGJ (Kosmik Music's YT channel)
And before you think this rAgA was Thyagaraja's alone, Dikshitar has composed a masterpiece (kshitIjA ramaNam) in it - https://www.youtube.com/watch?v=WZPOXMdI3Iw
And there's more from where that came from - https://www.youtube.com/watch?v=1ZVTizoRvu0
Gopalakrishna Bharati has made history with this one : https://www.youtube.com/watch?v=-MRsggIONhI
And now, over to all of you.
