Claudia Winkleman and Mika are back for another search for Britain's hidden musical talent, but this year's series of The Piano is introducing its biggest format change yet. Returning to Channel 4 this Sunday (12 July), the BAFTA-nominated series once again follows amateur pianists as they perform at some of the UK's busiest railway stations, hoping to catch the attention of the show's experts.
From emotional original compositions to classical masterpieces and contemporary favourites, performers of all ages and backgrounds take to public pianos in pursuit of a life-changing opportunity.
This time around, however, viewers can expect a major shake-up. After replacing Lang Lang as resident mentor last series, Grammy and Oscar-winning musician Jon Batiste is returning for another stint.

But rather than relying solely on Batiste and Mika to assess the performers, season four introduces a rotating line-up of internationally renowned guest mentors, with a different musical star joining the search at each stop.
Speaking about the change, Claudia teased: "We have some absolutely amazing mentors, and what will be fascinating is that Mika is going to be joined each time by different people."
What to Read Next
Mika agreed, explaining: "It brings a completely new energy to the show and a lot of different perspectives – each stop feels distinct, shaped by the musical instincts of whoever’s there."
The award-winning singer also shared his joy at the thought of working with Claudia again. "She is so brilliant at putting people at ease and has this wonderful way of connecting with everyone," he said. "She is very kind but also incredibly articulate and quick-witted!"
Leading the new additions is acclaimed concert pianist Tiffany Poon, who joins the team at Birmingham New Street. Known for her expressive performances and hugely popular online following, she'll help assess a group of hopefuls.
Elsewhere in the series, jazz-pop star Jamie Cullum heads to Glasgow Central Station, while legendary broadcaster, pianist and bandleader Jools Holland lends his expertise at London Bridge Station.
Japanese jazz virtuoso Hiromi joins Claudia and Mika in York, with internationally acclaimed classical pianist Alice Sara Ott completing the guest line-up at Manchester Piccadilly.
Despite the new faces, the heart of The Piano remains unchanged. Contestants won't be judged on technical perfection alone, with the series continuing to celebrate personal stories, resilience and the emotional connection people have with music.
Since launching in 2023, the show has become one of Channel 4's biggest factual entertainment successes, winning praise for its uplifting format and moving performances. Last year's series was won by 87-year-old Diane Newell, whose original composition 'Dreams' captured the hearts of both mentors and viewers at home.
As ever, Claudia will meet the pianists on the station concourse, while Mika and the guest mentor watch on before deciding who should progress. The series will culminate with a special concert at Birmingham's Symphony Hall, where the standout performers will take to one of the country's most prestigious stages.
With a refreshed line-up of musical experts, a new perspective at every station and another collection of inspiring stories just waiting to be told, The Piano is set to strike a fresh chord while staying true to the format that made it such a hit.
The Piano premieres on Sunday (12 July) from 9pm on Channel 4.
