Beyoncé says she crafted her stage persona to help her overcome challenges and give the best performances she can. "It's kind of like doing a movie. When you put on the wig and put on the clothes, you walk different," she says. "It's no different from anyone else. I feel like we all kind of have that thing that takes over."
Sasha Fierce usually appears right before Beyoncé is about to take the stage. "Usually when I hear the chords, when I put on my stilettos. Like the moment right before when you're nervous," she says. "Then Sasha Fierce appears, and my posture and the way I speak and everything is different."
Even though her new album is named for her other self, Beyoncé says she still wanted to share a piece of her true self on the record. "People, I think, are a little more familiar with my stage persona," she says. "I wanted to reveal more of who I am. And songs like 'Boy' and 'Halo' [are] more personal and more intimate and vulnerable."
