Menzel, who performed the hit "Frozen" song in Times Square, had trouble with the tune's final note; viewers took to the Internet to comment on her performance, and videos of the end of the song began to surface on YouTube.
On New Year's Day, Menzel tweeted a picture with the caption, "This is something I said in an interview a few months ago."
The quote read, "There are about 3 million notes in a two-and-a-half-hour musical; being a perfectionist, it took me a long time to realize that if I'm hitting 75 percent of them, I'm succeeding. Performing isn't only about the acrobatics and the high notes: It's staying in the moment, connecting with the audience in an authentic way, and making yourself real to them through the music. I am more than the notes I hit, and that's how I try to approach my life. You can't get it all right all the time, but you can try your best. If you've done that, all that's left is to accept your shortcomings and have the courage to try to overcome them."

In a recent interview with Playbill.com, Menzel said, "I wish I was better at putting up a façade, but I can't. And, I have learned to embrace my mistakes, whether it be in performance or just in life. I've learned that they usually, if I can breathe for a second and not freak out, [offer] some kind of learning moment. There's an opportunity to make something funny, to introduce myself in a different way to an audience or to just have a personal understanding about something. It can be a scary place to be, but it's really the only way that I know how to do it. "If I really want to be honest, there's the f*cked up part of you that likes to just spill out all my shortcomings before you can discover them! If I can admit them early on, then everybody else won't find them. I have more control over it. I guess if I'm really honest, there's that side to it, too. Rather I do it than you do it."
As for "Let It Go," she told Playbill.com, "I'm very happy for it to be my little friend that follows me everywhere. I thought I had a song like that in 'Defying Gravity,' and to this day I will always be grateful for that song as well and a couple of the songs from Rent, but to have such a huge crossover song not just for theatre audiences, it's something I've really wanted for a long time. I will always embrace it and love it and enjoy singing it, even if it's too f*cking high if I put it in the wrong key! As long as I can be healthy and sing it, I like to sing it."
