Watch Taylor Swift Stop Her London Eras Tour Show to Fix Her Piano: ‘This Is in the Wrong Key’

Taylor Swift‘s Eras Tour is almost always a well-oiled machine, so when something is amiss, she’s extremely quick to notice. 

Such was the case at the pop star’s Wembley concert Monday (Aug. 19), when she momentarily stopped her show to fix her piano after realizing it was tuned in the wrong key. In a video captured by a fan, she vamps on the keyboard while monologuing ahead of “Champagne Problems” before stopping short, saying, “I need to … this is in the wrong key.” 

“I just need to get to the keyboard,” she continues, attempting to lift the lid of the instrument as a crew member dressed in black rushes onto the stage to help her. “How do I get into here? I just know this is in the wrong key.” 

The 14-time Grammy winner and the stagehand eventually correct the problem, and Swift immediately gets back on track. “All right, awesome!” she cheers before remarking on the few minutes of rain London experienced during the show. “It’s raining, isn’t that nice? I think when it rains for more than six minutes, we can officially declare it a rain show. Rain shows are very, very special. Rain shows only chose a crowd that is fun enough to party and dance in the rain.” 

The following day, Swift performed her final show at Wembley, effectively closing out the Eras Tour’s European leg. She now has about a month of downtime before she resumes the trek in North America for one last run of dates in the United States and Canada in the final three months of the year.

Throughout her latest slew of London shows, Swift treated fans to multiple surprises, with Ed Sheeran joining her on stage at one point to perform a mashup of their collaborations “Everything Has Changed” and “End Game” along with his own smash “Thinking Out Loud.” On Tuesday (Aug. 20), the “Anti-Hero” singer brought out both Florence Welch for a surprise duet of their The Tortured Poets Department duet “Florida!!!” and Jack Antonoff for an acoustic guitar performance of “Death By a Thousand Cuts” and “Getaway Car.”
