Sigrid remembers her parents being called to school to collect her because her crying during a group performance was disturbing other children.
But the piano gave her a safe space.
"Piano is more of an introvert instrument," she says.
"It's the type of instrument where you're facing away from the crowd, you're looking into the piano.
"I just disappeared into that world and I was singing into the piano.
"I wasn't singing out into the room and it felt safe. It felt like I was creating my own world there."
