I would imagine anyone with any kind of musical background might have some advantage over a person who's never taken a voice lesson, played an instrument, taken any type of dance class, or done any activity that required you to be able to keep time to a beat since all that helps a person be able to dance.
However, just because you can do some of that or have done some of that in the past, doesn't mean you're going to be a great ballroom dancer or even be able to do the steps.
One of the things the judges talk about when critiquing someone is the "hold." You don't have a hold when you're doing ballet, tap, jazz, or hip hop in fact, when you're doing hip hop, you're more bent over.
A ballet dancer should stand tall and same with a tap dancer, but a tap dancer needs to be loose and have relaxed arms and hands. That's not the case in ballroom dancing.
I think it's kind of hard to pick all people who are so uncoordinated that they'd never look good dancing because I don't think people would want to watch.
As it is, aren't most of us hoping the show gets rid of Steve, the computer guy since he's not very good?
If everyone stunk, how would we be able to vote, lol?
