What is the name of the classical song covered in Ciara's "like a boy?"?

Question

I cant think of the name or artist

Answer 1

That is simply the song's basic chord progression played by strings -- it is not a classical piece at all.

To the responder below:

It perhaps is meant to imitate the style and gestures of Vivaldi's "Winter", but it is not at all the same piece.

Answer 2

Vivaldi's The Four Seasons (Winter)
