I know of most of the obvious changes that have been done with the new mass but I have never really fully studied the Mass and all its parts and details etc. so I don't know how it really differs from the Tridentine with full exactitute. I do know that in the Easter Mass before V2 the vidi aquam antiphon was sung before Mass began.

Did the Novus Ordo retain this? The last time I went to the novus Ordo was in 2008 and I never really paid attention to it, of course, since it was so boring and it never really interested me.
