What is this type of music called? Examples provided?

The music I'm thinking of is commonly used as background music in advertisements, especially those for action-packed movies.



For example, this is the trailer of Harry Potter %26amp; The Deathly Hallows Part 2: http://www.youtube.com/watch?v=_EC2tmFVN鈥?/a>



From 1:00 onwards, in the background, you can almost hear like a choir or something. I wanted to know what this music is called cause it is honestly really amazing.



Thanks for all the help guys! (:What is this type of music called? Examples provided?
