With her role in La La Land, Damien Chazelle’s modern take on the classic musical, Emma Stone emerged as a true Hollywood triple-threat: not only can she act, she can also sing and dance.

Did Emma Stone and Ryan Gosling sing?

Months of piano prep, shutting down an L.A. freeway and even Gosling’s own audition experience went into film. The magic behind the musical La La Land, starring a singing and dancing Emma Stone and Ryan Gosling, might appear effortless, but didn’t come easily.

What type of voice does Emma Stone have?

“I smoked when I was four,” she joked in an interview about her husky voice in an interview with Now Toronto in 2011. “I was like that baby in those YouTube videos [laughs]. No, I had colic from zero to six months.”

Its all him according to an interview: “In fact, there’s not a single close-up shot of [the character] Sebastian’s hands in the entire movie that’s a piano double,” director Damien Chazelle said at a press event for the movie.
