Song Beneath the Song

Written by series creator Shonda Rhimes and directed by Tony Phelan, it premiered on ABC in the United States on March 31, 2011.

The episode revolves around Callie Torres (Sara Ramirez) and Arizona Robbins (Jessica Capshaw), just after they are involved in a vehicular collision.

The episode opens with a voice-over narration from Callie Torres (Sara Ramirez) about the brain’s mystery, its ability to adapt, and how little we truly understand about its complexities, especially when it faces trauma.

She is moved into intensive care, while neonatal surgeon Addison Montgomery (Kate Walsh) is flown in by helicopter in case the baby has to be delivered prematurely.

Dr. Cristina Yang (Sandra Oh) suggests treating Torres with a high-risk but potentially effective cardiothoracic procedure she learned from her old mentor, Preston Burke (Isaiah Washington).

Her current mentor, Teddy Altman (Kim Raver), refuses to perform it, but when Torres's condition deteriorates and she is rushed back into surgery, Hunt agrees that Yang should attempt the procedure.

Once the surgery is complete, the doctors deal with their own affairs; Sloan's former partner Lexie Grey (Chyler Leigh) commits to her new relationship with resident Jackson Avery (Jesse Williams); Lexie's sister, Meredith Grey (Ellen Pompeo) confesses that she was jealous of Torres's pregnancy, which prompts her husband Derek Shepherd (Patrick Dempsey) to promise that they will have a child together; Altman tells Yang that she can no longer teach her; Sloan and Robbins bond over their shared parenthood.

[1] Rhimes felt that seasons 6 and 7 were the right time for the crew to "try anything and everything [they had] always wanted to do," and explained that she "finally [had] the right idea and the right talent to make [a musical episode] happen.

There are a lot of reasons – I was busy telling other awesome stories at Seattle Grace, [...] I was raising my tiny human, my musical talent involves oboe-playing and nothing else, the network thought it was the dumbest idea they’d ever heard of and refused to do it.

[2] Sara Ramirez used the opportunity to launch their career as a singer-songwriter; an alternate version of "The Story" is included on their debut EP, released four days prior to the episode's premiere.

"[6] Rhimes, executive producer Betsy Beers and director Tony Phelan selected songs that had become well-known by their use in Grey's Anatomy, and chose "the most iconic ones, the ones that best suited [their] singers, and the ones that made the most sense.

[8] The soundtrack also includes "How to Save a Life" by The Fray and "Running on Sunshine" by Jesus Jackson, performed as ensemble pieces by Ramirez, McKidd, Leigh, Daniel Sunjata, Scott Foley, Ellen Pompeo, Justin Chambers, Raver, Dane, and Capshaw.

"[4] Ramirez is the lead vocalist on "The Story" by Brandi Carlile,[7] and "Grace" by Kate Havnevik, which also features the other female cast members, including Leigh and Sarah Drew on the chorus.

[7][12] Horvath praised the cast's response to the episode, noting that only four performers had "serious vocal talent," while some had "barely sung in the shower" before.

[7] Those with professional singing experience include Ramirez, who won a Tony Award for their role in the musical Spamalot, and Wilson, who appeared in the Broadway production of Caroline, or Change.

[4] Recurring cast member Sunjata stated that singing was "a bit out of [his] comfort zone," but found it an "interesting challenge,"[13] and McKidd deemed it "very exciting to do something that's completely out on a limb for the show.

"[4] Entertainment Weekly's Dan Snierson predicted heavy use of Auto Tune,[15] though fellow EW writer Jennifer Armstrong was optimistic that the episode would be a success, commenting: "I have faith.

The rating was the second-highest of the seventh season until that point, and a 30% increase from the previous episode, "This is How We Do It," which was watched by 2.4 million fewer viewers.

"[21] Even though Boston Herald's critic Mark Perigard was not a fan of the concept, saying "the Grey's Anatomy event proved how tricky it is for an established show, especially a drama, to pull off a musical episode," he did like several actors' performances.

"[22] Lyneka Little of The Wall Street Journal wrote, "If Glee and ER had a baby it would be tonight’s episode of the medical drama Grey’s Anatomy titled 'Song Beneath the Song'.

"[20] In his review of the episode Alan Sepinwall of HitFix wrote "Like Grey's Anatomy as a whole, some parts were unintentionally silly, others were surprisingly powerful, and it was rarely dull, at least.

[25] It was included in TV Guide's list "The Worst Of 2011" saying, "Sara Ramirez has powerhouse pipes, but what this episode desperately needed was a better playlist.
