Taylor Swift's Eras Tour book revelations: Inside the 'roomba' and the iconic stage dive

Taylor Swift has a "big reputation" and now, she has a big "Eras Tour" book, too, with special behind-the-scenes details and her thoughts about some of the songs.

On Black Friday, Swift released a book celebrating her groundbreaking world tour, which became the world's highest-grossing concert tour ever. The tour, which kicked off in Glendale, Arizona in March 2023, was Swift's first tour in six years and inspired a theatrical concert film, which is now the highest-grossing concert film ever.

The Eras Tour, which ends Dec. 8 in Vancouver, featured shows that last nearly four hours and also made history as the first to ever earn $1 billion.

The book, available exclusively at Target, $39.99, features revelations from each of her "eras," coined by fans to describe Swift's world during each of her studio albums. Swift also teased the next chapter of her career, writing "see you next era..." in a letter to fans. The book goes for sale online on Nov. 30.

"Taylor Swift | The Eras Tour Book" is 256 pages and features over 500 images, featuring exclusive performance photos from each era of music, along with rehearsal shots and behind-the-scenes glimpses of instruments, costumes, set creations and designer sketches.

Here are the biggest spoilers — and surprises — from Swift's "Eras Tour" book.

Taylor Swift reveals why ‘Enchanted’ is only song from ‘Speak Now’

Swift said she chose the “epic” song “to represent this album because it was always my favorite song on the album,” adding that “even though it was never chosen as a single, the fans made sure it became one of the most recognizable songs” from that era.

She called that phenomenon “one of my favorite things” over her two-decade-long career.

Taylor Swift says why each Eras Tour show starts with ‘Lover’ era

The “Lover” writer said the tour began with the era of the same name because of the lyric “it’s been a long time coming” from her song “Miss Americana & The Heartbreak Prince.”

“We had to open with ‘Cruel Summer’ to blast us into the energy of this show,” Swift told fans in the book.

Taylor Swift addresses viral ‘Red’ hat trend (and surprise!)

Swift enlisted the help of British designer Ashish Gupta to recreate looks from the “22” video, including the iconic outfit of the pop star in a black hat, oversized t-shirt, shorts and loafers.

The “All Too Well” hitmaker gave away a black hat to a fan at every show, which went viral on TikTok. In the book, she says each hat “was signed on the inside.”

Taylor Swift's tour is ending. For girls, its impact is far from over.

The ‘TTPD’ ‘rover’ platform is driven by a crew member

Swift’s crew members weren’t “Down Bad” on The Eras Tour but one was down on the floor, operating a Roomba-like platform that swept across the stage as the pop star stood on it.

“The ‘rover’ platform I travel on is actually operated by a crew member, who lays inside the platform and drives it from inside,” Swift wrote, calling the added “TTPD” portion of the tour “ambitious as hell.”

The "TTPD" section was added to the tour after Swift released the album in April.

Taylor Swift's brother, parents bedazzled her 'Fearless' guitar for Eras Tour

In the book, the Pennsylvania native revealed that her brother Austin Swift, a filmmaker, and parents Andrea and Scott Swift bedazzled her "Fearless" guitar by hand.

Swift said she wanted to "harken back" to the high school-aged season of her life where she made "Fearless" during the tour by "frolicking across stages with my crystal covered guitar (which was bedazzled by my parents and brother)."

Taylor Swift’s viral jump into the stage is accomplished with the help of a shocking safety device

Swift is known for making waves with her music, but one Olympic swimming-like entrance into the stage during the acoustic section wowed social media again and again.

In the book, she reveals how they accomplished the dive.

“At the end of the second song, the stage becomes an ocean and I ‘dive’ into it, which involves a lot of blind faith and a big airbag under the stage,” calling the airbag jump “the coolest illusion of the night” because it caused “shock, horror, and elation.”

“Mission accomplished,” she wrote.

‘Mastermind’ chess dance creates checkmate sequence on Eras Tour

Swift and her dancers checked one specific thing off their list during The Eras Tour. The pop star says in the "Eras Tour" book that her team recreated a chessboard during “Mastermind” and “when I signal the dancers to move to different sports on the board, they actually create the exact sequence for checkmate.”

Taylor Swift band, dancers have pre-show Eras Tour ritual that made her cry

The “Cruel Summer” singer said that she joins her band and dancers before every show, and someone delivers a speech to get them hyped ahead of their performance as seen in the "I Can Do It With A Broken Heart" video.

“Whoever went last picks the person to go that night,” she wrote, adding that “we put our hands in the middle and all chant the same thing together.” Then, it’s go time.

Swift also said many of the speeches — which range from motivational in tone to a simple share — have made her cry.
