Witches and saviors. Royalty and villainy. Curses and reverses.
Over the past six seasons, Once Upon a Time has taken viewers on a roller coaster of fairy-tale proportions. The only place it hasn’t gone? To the piano. This Sunday, May 7, the ABC hit fantasy show sings—literally and figuratively. In the episode that finally sees Emma and Hook walk down the aisle, something magical causes our favorites to break into song. Rather than go with traditional Disney tunes (see why below!), creators and executive producers Eddy Kitsis and Adam Horowitz selected Alan Zachary and Michael Weiner to compose seven original songs for the show. That, in and of itself, is reason for Disney fans to celebrate: Zachary and Weiner are the talented two who wrote the music for the outstanding show Twice Charmed which plays on the Disney Magic.
We sat down with Kitsis and Horowitz to get the scoop on all the high notes the episode will hit. (Plus we have two, exclusive Hook-tastic shots to share!)

Exclusive: Captain Killian “Hook” Jones (Colin O’Donoghue) in this Sunday’s musical episode.
What made you decide to do a musical episode?
Kitsis: Our show naturally lends itself to a musical. So the first year, we were like, no, we’re not going to do it. Truthfully, we were terrified ’cause we had never done one, and when we met Michael and Alan, it started to make it less scary. And then less scary turned into all of us being really excited and inspired.
Why did you decide not to use Disney songs?
Kitsis: We opened the whole show on the end of what people thought the Snow White story was, so we felt like it would be a cheat to just have somebody sing a song like “When You Wish Upon a Star” because the show always pushed us to be original in our telling of these fairy tales. We felt the music had to comply with that.
Horowitz: Look at Beauty and the Beast, for example, and a song like “Be Our Guest.” That song is perfect for that story in that movie and those characters, but to try to shoehorn that into our show, that’s not the story we’re telling.
Will the wedding be full of song?
Kitsis: The wedding will be full of song and cheer because you can’t have a musical episode and have a wedding without a song. The wedding encompasses everybody, the town, and how much Emma means to everybody, and at the same time, it’s still personal and intimate between the two of them.
Any hints as to what causes people to break out in song, besides magic?
Kitsis: I would say, in true Disney fashion, when you wish upon a star.

Exclusive: Captain Killian “Hook” Jones (Colin O’Donoghue) and pirates in this Sunday’s musical episode.
What did the cast say when you told them they were going to be doing a musical?
Kitsis: Can I sing? Can I be in it?
Horowitz: Our cast is up for any challenge, and they always manage to not only meet but exceed our expectations. They were super-collaborative with Alan and Michael, sitting down with them and working with them. The guys really tailored stuff to everybody, and each different character has a different style of song that we think is suitable to their character.
Did the cast have musical experience?
Kitsis: Josh Dallas was in London on the West End for years. Jennifer Morrison and Ginnifer Goodwin both had musical theatre background. Lana could sing. Rebecca Mader has such an incredible voice. So maybe their careers don’t show that credit but their talent does.
Can you talk about how Emma’s walls come down through the music?
Kitsis: In musicals we sing what we can’t express or what’s in our head. So for Emma, we’ve spent six seasons watching her slowly bring her walls down, and this wedding is the ultimate symbol of that. She’s embraced her family, she’s embraced her future, and she’s ready to open her heart up again. We felt like the musical was perfect for that because that intimate internal thing in her head would be best expressed through singing.
Will there be any special guests?
Kitsis: We believe there will be some surprise guests and some of our favorite storybook residents singing.
What have been highlights of this past season for you?
Kitsis: It was fun to do Aladdin and Jasmine and a magic carpet ride. It’s great for us to see the six seasons and the history of the show really start to pay off. I loved watching the evil queen face herself and move on. I loved watching Rumpelstiltskin put his child first.
Horowitz: In addition to the musical, I’d say the season finale has come together in a way where it really sums up so many different things for so many different characters.
What do you feel has been the overarching theme this year for the show?
Kitsis: I think the main one has been about belief. The belief that things can get better. The belief that you can get better. Believing in magic and believing in help, and I think the finale really is going to illustrate that.
Horowitz: Yeah, I’d agree with that. I’d say that there’s a surprising amount of strength and fortitude you need to have belief in anything. And it really comes to a head at the end of the season.
