So, just taking the first line, and not worrying about the length of each note, I would notate that in Indian notation as
('Ni Sa Re Ga, Re Ga Da Pa Ga Re Sa 'Dha),
which is the equivalent of: ('Ti Do Re Mi, Re Mi La So Mi Re Do 'La)
So, you can see, if a song did not (for some reason) have the Sa or the Do in it, I still know based on the positions of Re, Mi, etc., where the Do is.
