Does anyone know what the beautiful piano piece at the opening of FFX-2 is called? Actually, I'm more interested in downloading it and/or finding sheet music for it.

Any help is appreciated. Thanks.

It's called "Eternity - Memory of Lightwaves".

Don't know about any sheet music though...

You might also find it listed as KUON Memories of Waves and Light

I have sheet music for Yuna's Ballad and 1000 Words, but not for that song. Sorry =\
