I showed the song to my daughter who asked me to repeat atleast 7 times. first time it was for baby shalini whom she calls by 'her' name.
Then it was nedumudi venu's antics which she recognizes clearly as the ones I do when I play with her.
And then the music - by the end of 6th time she starts humming and then I know how simple the song is to really hum - this nature is very common among all classic lullabies, Right from Brahm's lullaby to namma oor thaalaatus. There is no unnecessary 'flurry' of notes in the composition...
