Two piano prodigies, one bench, and a rivalry that runs for almost ten years. Four Hands, Two Sonatas wrapped up on October 4, and if the finale left you staring at the screen, you’re not alone. The good news is that a lot of what you saw on screen is real. A university campus in Daegu, concert halls just outside Seoul, a subway exit you’ve probably walked past, and the rain-soaked streets of Prague.
Here’s what’s confirmed, what fans have pinned down, and how to visit each one.

What Is Four Hands, Two Sonatas About?
The title comes from piano-duet slang: “four hands” means two pianists sharing one keyboard. Kang Bi-o (Song Kang) has always been first, a perfectionist raised under the weight of his grandfather, a world-famous conductor. Choi Jeong-yo (Lee Jun-young) is the boy who beat him once at a junior competition, then disappeared from music to support his family.
They meet again at an elite arts high school, get paired for a four-hands duet, and the story follows them from teenage rivals to professional musicians. Along the way there’s a competition in Prague that changes everything for both of them. (This guide stays spoiler-light, so the twists stay yours to discover.)
The show was a weekend hit. Episode 1 topped its time slot among cable channels, according to Edaily, and Lee Jun-young held the No. 1 spot for cast buzz six weeks in a row, per Topstar News.
A Quick Note on How These Locations Were Checked
Only two filming places have been publicly confirmed: Keimyung University, in a university release carried by Herald Economy, and Prague, through tvN’s official behind-the-scenes video.
Most of the Korean spots below come from a large fan-compiled list, which KDramaPins has mapped. Fan lists are usually accurate for buildings you can recognize on screen, but they aren’t official. Each section below says clearly which kind it is.
Keimyung University, Daegu (Confirmed)
If the red-brick buildings and ivy-covered walls looked a little too old-world for a Seoul arts school, that’s because they’re in Daegu. Keimyung University says its campus hosted the filming of Four Hands, alongside a long list of classics like Boys Over Flowers, Mr. Sunshine and The Last Princess, Herald Economy reports. The same article counts more than 120 films and dramas shot there.
Keimyung has two campuses worth knowing:
- Daemyeong Campus is the older one, with classical architecture that feels almost European.
- Seongseo Campus is the newer one, with red-brick and more modern buildings.
The release doesn’t say which campus or building Four Hands used, so if you want to see both, give yourself half a day.
Can you visit? Yes. Both campuses are open to walk around, as long as you respect classes and don’t go inside lecture buildings. The Seongseo Campus has its own subway stop, Keimyung University Station on Daegu Metro Line 2, about a minute’s walk from a campus entrance.
Turning it into a weekend? Here’s the full guide to things to do in Daegu.
The Concert Halls: Bucheon Arts Center and Art Center Incheon (Fan-Identified)
A piano drama lives or dies by its stage scenes. Fan location lists include several real concert halls, and two of the easiest to visit are west of Seoul, according to KDramaPins’ map. The lists don’t say which performance was filmed where, so check the venue against the episode if you want an exact match.
Bucheon Arts Center
One of the newest classical halls in the Seoul area, opened in 2023 on the grounds of Bucheon City Hall. It’s a dedicated classical concert venue, so it’s easy to see why a piano drama would film here.
Can you visit? Yes, by buying a concert ticket. Check the program on the Bucheon Arts Center Instagram. Take Seoul Subway Line 7 to Bucheon City Hall Station, which is also signed as Bucheon Arts Center Station.
Art Center Incheon
This concert hall is in Songdo International City, Incheon’s futuristic new district. Fans also list other Incheon venues used in the drama, such as Elim Art Center and Incheon Airport Terminal 2.
Can you visit? Yes. The outside is free to walk around, and you can see the inside by booking a concert.
Combining it with a day out in Songdo? Here are the best things to do in Songdo, Incheon.
Seoul Arts Center and the Sheet-Music Shop (Fan-Identified)
The Seoul Arts Center (예술의전당) in Seocho is Korea’s classical-music heartland, so it’s no surprise it shows up. Fan lists also include Daehan Eumaksa (대한음악사), a well-known sheet-music shop listed at the same address, per KDramaPins. The nearby bus stop and the crosswalk on Nambusunhwan-ro are on the fan list too.
Can you visit? Yes. The grounds are free, and the music shop is a regular store. Nambu Bus Terminal Station (Line 3) is the usual way in, followed by a short walk or shuttle.
Nakwon Arcade, Jongno (Fan-Identified)
Every musician in Seoul knows Nakwon Arcade (낙원상가), a 1960s building packed with floor after floor of instrument shops. It turns up in the episode 11 and 12 behind-the-scenes material, per Namuwiki, and fans list it as a filming spot.
Can you visit? Yes, and it’s free to wander. Go on a weekday afternoon when the shops are open, then walk to Ikseon-dong for dinner.
Dongnimmun Station, Exit 5 (Fan-Identified)
Not every location is a grand stage. Fan lists also include Exit 5 of Dongnimmun Station on Seoul Subway Line 3, one of the drama’s everyday street scenes, per KDramaPins.
Can you visit? Yes. While you’re there, Independence Gate and Seodaemun Prison History Hall are right next to the station.
Inwang Middle School, Hongje-dong (Fan-Identified, Not Open to Visitors)
Fans list Inwang Middle School in Hongje-dong, Seodaemun-gu, among the drama’s school locations. It’s a frequent filming spot that has also stood in for schools in Crash Course in Romance, per its Namuwiki entry. One location list circulating online says it was Choi Jeong-yo’s school, but no official or press source confirms which scenes were filmed here.
Can you visit? No. It’s a working school, so look from the street at most and don’t try to go in.

Prague, Czech Republic (Confirmed City, Specific Spots Unconfirmed)
Prague is where the story turns. In episodes 5 and 6, Bi-o goes to Prague for an international competition (named in recaps as the fictional Prague Harmonie International Competition), and the Czech Republic comes back again near the end of the series. The cast really did shoot there: tvN’s behind-the-scenes clip shows Song Kang and Lee Jun-young filming a fight scene in pouring rain on Prague’s streets, Wikitree reports.
What hasn’t been confirmed is which streets and buildings. tvN hasn’t released a list, and none of the press coverage names specific sites. So the places below are not confirmed filming spots. They’re the Prague landmarks that best match the drama’s world, a grand concert hall, the river views and the old bridges, and they’re the ones worth putting on your list if the drama made you want to go.
Rudolfinum (Dvořák Hall)
If you’re picturing a grand 19th-century concert hall for an international piano competition in Prague, this is the real-life version, although the drama’s competition venue hasn’t been officially identified. The Rudolfinum opened in 1885 on the bank of the Vltava, and its Dvořák Hall has been home to the Czech Philharmonic since 1946, per Wikipedia. It’s also one of the main venues of the Prague Spring festival every May and June.
Can you visit? Yes, the easiest way is to book a concert. The Galerie Rudolfinum at the back of the building also runs contemporary art exhibitions.
Vyšehrad
The old fortress on a cliff above the Vltava is the quieter, more local side of Prague, with the twin spires of the Basilica of St. Peter and St. Paul and big views over the river. It’s the place to go for the river-and-skyline views that Prague is famous for.
Can you visit? Yes, it’s free to walk the ramparts. Take Metro Line C to Vyšehrad Station and walk about 10 minutes.
Charles Bridge
The 14th-century stone bridge lined with Baroque statues is the classic Prague walking shot, and the first place most K-drama fans head to.
Can you visit? Yes, any time, for free. Go at sunrise if you want it nearly to yourself.

A Four Hands Fan Route
If you want to follow the drama in Korea, here’s an easy way to split it:
- Seoul day: Nakwon Arcade in the morning, Dongnimmun Station and Seodaemun in the afternoon, then the Seoul Arts Center for an evening concert.
- West of Seoul day: Bucheon Arts Center, then on to Songdo for Art Center Incheon at sunset. Both are reachable by subway.
- Daegu day trip: KTX to Dongdaegu (under two hours from Seoul), then Daegu Metro Line 1, changing to Line 2 at Banwoldang, to Keimyung University Station.
Booking a concert at any of the halls is the best way to see the inside, and the closest you’ll get to Bi-o’s view from the stage.
