Help finding documentary title

[WhoKnows]

Hi there!

I hope somebody can help me here. I'm looking for the title of a series
of documentary I saw long ago on TV. They were themed according to the
environment (water, air, ground) and there was this classical music as
background adjusted with images in order to create incredible effects
(fishes or birds moving according to music etc.)

Does anyone know the title of this series?

Thank you very much.
