You might have to ask a vocal teacher but I think it is mainly some one just vocalizing and not really singing. I'm not in school.
xd And I agree that it doesn't really seem like words, but a hymn like others said.
I think someone mentioned in another community that they thought it was like share-ware for musicians, I just wish I could find out what it was called.
I know it was in the Da Vinci Code trailer...
I know that the woman who worked on Episode II and III's music used her own language, Kajurian, because sometimes vocals could be an instrument, but, I figured that since this was all over the place it might have some form of significance ^^;
