I've been thinking for quite a while about what is unique about the song. Honestly, except for pointing out the 'Dvitiyakshara Prasam' I mentioned in earlier songs too, I couldn't come up with much. This is a typical Valaji. Of course, that doesn't mean this isn't a good composition. In fact, this is a great composition that completely relaxes a listener even before the pallavi is over. For all the GNB critics who think his music is nothing but speed, this composition is a fine example of his idea of melody. (And this point is reinforced by his other composition Mamakuleswaram in Thodi, a very slow piece)
There are two striking features in GNB's kriti rendition. One is Briga and the Other is Bigu. The two features are often juxtaposed one after another, creating a stunning effect. In the Pallavi of this Kriti, the 'Briga' at 'NinnE' and the cascasding 'Bigus' 'nIvEyani' is an example of this effect. I'm not sure if Sindhu's swarakshara usage at 'Ga dhA' in Anu Pallavi was conceived by GNB. It sounds fantastic and that is what matters. And I think 'Vanditha muni jana' is a wonderful place for neraval. If it is Valaji, I would any day swap the kalpana swarams for 'first speed' neraval.
