Does the been not affect Nayantara?

In the intro of Nayantara she herself is shown playing the been like a snake charmer. How is she able to play the been?

I guess because 25 years were not complete. So according to the curse she was nothing more than a  human lass. Even Vrushali said 2 days were left, probably that’s why she didn’t enter the temple either.

But she was shown turning into a snake.
