The crowd was just family and a few elderly parishioners—but to Beyoncé, it was the Superdome. She closed her eyes, remembering the way her grandmother, Miss Hattie, had taught her to breathe. "From the belly, baby," she would whisper. "Let God push it out."

The piano player struck a C chord. Then another.

She didn't smile. She just walked off the stage, sat down next to her little sister, Solange, and asked, "Can we get ice cream now?"

Years later, in a sweaty rehearsal studio, that same girl would be a teenager. The group was called Girls Tyme, then something else, then finally Destiny's Child . The record deals fell through. Managers lied. Other groups got signed instead.

That was the secret. Even at seven, Beyoncé knew the difference between performing and living. On stage, she was a hurricane. Off stage, she was quiet. A watcher. A student.
