In this video, Beyoncé is on her way to the Oprah Winfrey Show. Se will sing there but she is suffering from hoarseness.
Off course she wants to sing with a clear voice. Because her technique is so good, she manages to sing the song pretty well. With a little cheating now and then she manages to sound pretty clear. For example, she uses more air pressure then she should and she uses a wobbling jaw to produce vibrato
The downside of cheating is that the voice doesn't sound as open and free as it normally does.
