Regarding "ULiyin Oasai" , I read few of you mentioning "Kaalathai vendra " song to be based on Kiravani . I beg to differ. I feel it is loosely based on "VakuLabharanam" scale. Iam reminded of hysterisis whenever I listen to Bhavathaarini with that annoying lag.
Coming back to the song, IR has once again creatively interjected the shenoy or nadhaswaram sound in one of the charanams , befitting the lyrics . I remember in "vayasu puLLa" song from the jinxed movie "en aNNan" , preceding the line "nadhaswaram munnala thaan naanum neeyum pinnodu thaan" , there comes a very spectacular nadhaswaram piece in the middle , playing the "mohanam" .
