Many pop and country singers these days are using their belt voices. Unfortunately, many of them are using their belt voices incorrectly without considering the damage that they could be causing to their vocal chords. They may sound great now, but they might not have much of a voice later on. In my opinion, one such person who is wearing her voice out prematurely is Christina Aguilera. Aside from wrong words, notice in this clip how on several of the high notes, she is attempting to belt them and her voice has a very scratchy and oft times flat sound. In several instances, she makes it sound intentional by quickly moving from the note she’s holding (belting) by doing vocal flourishes. It may sound impressive, but it’s her voice’s way of telling her that it can’t keep this up.  If I was working so hard to make my notes sound good, I might forget the words too.

A good example of a pop singer who seems to be very talented with her belt voice is Kelly Clarkson. She seems to be in good control of it, and honestly, I hope that it lasts her.

Here’s a helpful article from Wikipedia for more information on belt voice.
