I'm confused about what I should be listening for here. How is it a lipsync (and the same recording in both performances) if the adlibs she does after the big note are completely different in each performance? Unless you're just referring to that note, in which case considering how effected it is I don't get what the issue is.
The point of the comparison is to show that everything else
but that run is different - she'd never actually be able to execute that run in exactly the same fashion. And I don't know what you mean by it's affected. It's not -- it's the same album-cut run for the SYTYCD.
Same goes for that Today Show performance. If you notice how front-and-center her voice is on NMT, then when that "tonight" belt comes, it suddenly disappears and sounds like it's muted compared to when she actually is singing live. Now, this is not an indication that muted necessarily means it's lipped, but it is curious that the vocal quality is so different for the belt when the mic is an inch from her mouth and she doesn't sound as loud as she does during the rest of the song. It's even more curious when that "belt" is an exact match of the album vocal, which is the de facto indicator. Compare it to her
Oprah performance of NMT -- that one is live.
There are differences in what she does when she does lip. The SYTYCD is a direct album rip. Ain't No Other Man on tour is an album rip. Hurt is lipped but a redone vocal she reuses.
Show me a performance where you think she sounds exactly like the record and I can guarantee you that if it's live, it will sound different when compared to the album vocal or any other live version. If not, then it's probably lipped. Of course,
Hurt on tour being the caveat because that's not an album cut, but if you layer every single performance she did on tour, her breathing, timing, ad libs and runs all sound exactly the same up to the bridge (where it
is live). Also note how
far her mouth is from the mic when she
is belting live.
Not entirely true. If you're going for a sustained run like the kind Mariah tends to do it is easier to work up to a note. However, if you're belting out quickly like Xtina does at the end of that Burlesque performance it's easier to start out at the top because you have more air to work with to, well, basically blast out the note. Notice that she only holds that top note for the briefest moment before quickly running down.
So why does she lip it, then?
I know it's hard when you discover your fav lips, I really do. Celine (who has to be the
best lipper in the
business) and Mariah are notorious for lipping. I've only seen one performance where Whitney
tried to.
