As a young child growing up in South Africa, Gillian Power sang in school and church choirs.
"It was one of the things I remember from that time as so deeply joyful," Power says.
Now, Power is in her early forties. She came out publicly as transgender in early 2014. Her transition has included voice lessons.
"Many transgender people really struggle with their voice on many levels – their speaking voice, their telephone voice, their radio voice — and especially their singing voice," she says.
