The drama tells the story of talented students at an arts high school who share a deep passion for music. Their journey takes them from their teenage years into adulthood as professional pianists. The title refers to a piano technique where two people play together on one piano.
Song Kang’s return has been one of the most talked-about topics in the K-drama world. Fans have been waiting to see him back on screen after his military enlistment. With “Four Hands, Two Sonatas,” he is ready to show a new side of himself as an actor.
Why Song Kang Chose “Four Hands, Two Sonatas”
The script for “Four Hands, Two Sonatas” left a strong impression on Song Kang from the very beginning. He admitted that even after reading other projects, this particular story stayed with him.
“After I first read the script, the script for ‘Four Hands, Two Sonatas’ kept lingering in my mind even while I was reading other projects.”
His love for music also played a big role in his decision. Song Kang has always enjoyed listening to piano music in his daily life. This personal connection made the project even more appealing to him.
“I’ve always liked the piano as an instrument, to the point that I listen to piano pieces and jazz piano in my everyday life. So I think I was even more drawn to this project because it centers on music.”
The actor saw this as a chance to combine his personal interests with his work as an actor. The musical theme of the drama gave him a reason to explore something he already loved on a deeper level.
Meet Kang Bi Oh: The Perfectionist Piano Genius
Song Kang plays Kang Bi Oh, a piano prodigy who is known for his flawless skills. He is a student at Korea Arts High School and is recognized as a next-generation pianist. Bi Oh maintains his top position through intense dedication, practicing for 10 hours every day.
On the outside, Bi Oh appears confident and self-assured. But beneath that perfect image lies a world of pressure and anxiety. His family, especially his grandfather who is a world-renowned conductor, puts enormous expectations on him. He feels that he can only make his mother happy by being the best in the world.
Song Kang described his character in a very personal way. He explained that for Bi Oh, the piano is both a way to express himself and a heavy burden.
“For Kang Bi Oh, the piano is both a language through which he communicates with the world and a heavy presence through which he must prove himself. At the same time, I think it is everything that drives Kang Bi Oh and causes the greatest upheaval in his life.”
This description shows that Bi Oh’s relationship with music is complicated. It gives him purpose but also creates conflict in his life. The character struggles with the weight of expectations while trying to find his own voice through music.
The Story of Friendship, Rivalry, and Growth
“Four Hands, Two Sonatas” is more than just a story about music. It is about the relationships that form between young people who share a common dream. The drama follows Kang Bi Oh (Song Kang) , Choi Jung Yo (Lee Jun Young) , and Hong Jae In (Jang Gyuri) as they meet at an arts high school and form a special bond.
Bi Oh and Jung Yo are both piano majors. They start as friends who play together beautifully. But their relationship changes when comparisons from the outside world begin to tear them apart. Bi Oh faces harsh criticism from his mother, who demands nothing less than first place. Meanwhile, Jung Yo gains attention for his natural musical talent.
The tension between them grows. Jung Yo eventually asks Bi Oh, “Are you deliberately distancing yourself from me?” Bi Oh can only stare back in silence. The once-perfect partnership begins to crack under the pressure.
The story also follows the characters over a 10-year period, from age 17 to 27. Viewers will see how their friendships and relationships change as they grow into adults. The drama explores whether the bonds formed during their teenage years remain strong.
Taking On the Role of a Pianist
Playing a pianist required Song Kang to learn new skills. He took piano lessons to prepare for the role. His character is a prodigy who has been playing since childhood, so the actor had to make his performance look convincing.
The drama features scenes where the characters perform together. In one teaser, Bi Oh and Jung Yo are shown playing a four-hands piece together. They coordinate seamlessly, dividing tasks by saying, “You take the pedals, I’ll handle the sheet music”. Their chemistry on the keys shows the deep trust they share as musical partners.
Song Kang’s preparation went beyond just learning to play the piano. He also had to understand the mindset of a perfectionist musician. His character is someone who has dedicated his life to his craft. The pressure to stay at the top takes a toll on him emotionally.
