Translation result\"\uc544\ud30c\uc2dc\uc624\ub098\" [Herald Business=Reporter Seung-hee Ko] Small hands tap the broad shoulder of a cello. Fingertips shape sound before the bow finds its line. A violin glides over a low piano pulse. The music swells and crashes like hair caught in a sudden gust. Though their faces are still youthful, the teenagers\u2019 playing is daring\u2014like a covert team slipping into an adult world. With Piazzolla\u2019s irregular rhythms casting a shadow and jazz and tango fueling their fire, the three musicians are forging a performance identity distinct from earlier \u201cprodigies.\u201d<\/p>\n

The \u201cTango-style Improvisation\u201d uploaded to the YouTube channel Let\u2019s KLAY shot to 140,000 views after Kim Ju-ho\u2019s piece\u2014written at 13 while he was a first grader at Yewon School\u2014was posted in 2024. It quickly joined the channel\u2019s top three most-viewed videos. Viewers left comments like, \u201cDid a 13-year-old really write this?\u201d and \u201cAn astonishing trio.\u201d The Appassiona Trio is made up of Kim Ju-ho (born 2010; composer, piano), Jeong Hyun-jun (violin) and Jeon Seo-u (cello).<\/p>\n

They are a new kind of teenage ensemble. Now in their fourth year as a group, they\u2019ve just set another milestone: Appassiona Trio is the youngest ensemble ever invited to the Seoul Spring Chamber Music Festival (SSF), now in its 21st year. While soloists such as Cho Seong-jin and Sunwoo Yekwon have appeared on the SSF stage at a young age, this is the first time a teenage ensemble has been spotlighted.<\/p>\n

When I met them in a practice room in Seocho-dong, Seoul, the three laughed and said, \u201cWe formed in 2023 as first-year middle school students, so technically we\u2019re a four-year group now, but we had a two-year break in between.\u201d In that light, this SSF appearance is a comeback.<\/p>\n

\n A composer-driven trio from Yewon School\u2026 \u201cTalented kids stick together\u201d\n<\/div>\n

Middle school opened a different world. Kim Ju-ho set the trio in motion. In spring 2023, during an improvement recital for first-year students at Yewon, he was looking for partners to play his composition. The Friday concerts in the new auditorium have been a school tradition since 1972, and within that tradition Kim sought collaborators to bring his music alive.<\/p>\n

He remembered, \u201cThe improvement recital was an opportunity to hear other students and get a sense of the national level.\u201d<\/p>\n

\"\uc544\ud30c\uc2dc\uc624\ub098\" The first recruit was violinist Jeong Hyun-jun. Kim recalled, \u201cI was struck by a short Stravinsky piece Hyun-jun played\u2014the lonely feeling stuck with me. He played with his hair flying and was really impressive.\u201d Hyun-jun combined sensitivity and technique. Then Jeon Seo-u\u2014\u201ca lively player who could hold his own between two boys,\u201d and someone \u201cknown around school for being very skilled\u201d\u2014joined, and the trio took shape.<\/p>\n

Both players welcomed the idea because they wanted to make chamber music together. Stepping into middle school expanded their social and musical worlds, giving them a chance to collaborate rather than work alone. \u201cWe both wanted to try chamber music,\u201d Jeong and Jeon said. Jeon, who lived in Canada until fourth grade and played chamber music there, said he wanted to pick that up again after returning to Korea. Jeong recalled, \u201cI think I was the one who first said I wanted to do it,\u201d and he embraced Kim\u2019s proposal. At the time, Kim\u2014then attending the Korea Arts Education Center for Gifted Students\u2014was already known among first graders as \u201ca talented young composer.\u201d<\/p>\n

The piece that bound them\u2014and that they\u2019ll perform at SSF\u2014is that very \u201cTango-style Improvisation.\u201d At 3 minutes and 36 seconds, the work matches the trio\u2019s name with its bold energy.<\/p>\n

Kim said, \u201cI was hungry for positive feedback from friends. Composers don\u2019t get many chances to present work, so I wanted it to leave a mark. I wrote the tango because I wanted to\u2014Piazzolla left an impression on me, and I\u2019m interested in modern pieces that stem from jazz, like Kapustin.\u201d The trio even experiments with treating the cello percussively over jazz-inflected rhythms. Kim laughed, \u201cHonestly, I was a little carried away back then.\u201d The piece came together intuitively: a single note would feel right, and without a formal plan, subconscious musical instincts shaped the structure.<\/p>\n

\"7\uc0b4\uc5d0\" What makes this trio particularly engaging is that the composer is part of the ensemble. Having a living composer at rehearsal is a rare and valuable experience for the two instrumentalists.<\/p>\n

Jeong said, \u201cInterpreting works by dead composers can be tricky, but working with Ju-ho felt easier. Rather than feeling pressure, his presence offered interpretation coaching.\u201d Jeon agreed: \u201cBecause Ju-ho is alive, we can ask what he wants and suggest ideas. It makes the process more relaxed.\u201d Kim admitted, \u201cI was young then and didn\u2019t direct much.\u201d<\/p>\n

\u201cBack then I only knew piano, so I didn\u2019t understand other instruments well. Looking back, my notation was messy. Preparing for this concert, I basically had to redo and clean it up.\u201d (Kim Ju-ho)<\/p>\n

\n A trio in growth \u2014 time to stamp our sound\n<\/div>\n

Appassiona\u2019s identity is growth: the composer and performers growing together. Their music has matured with them. The piece they pulled out again after two years has effectively become version 2.0. The members notice one another\u2019s development. Jeong said, \u201cJu-ho\u2019s music is maturing. Each piece has a distinct color; his musical world feels clearer over time.\u201d<\/p>\n

\"\ucd08\ub4f1\ud559\uad50\" Jeon added, \u201cI think I have a lot more to say now than before.\u201d Kim immediately teased, \u201cThat just means he says things that are hard to understand,\u201d and they laughed. Jeong often plays mediator, translating Kim\u2019s ideas for Jeon and keeping the team centered. They tease each other like typical sixteen-year-olds\u2014bickering one moment, making up the next\u2014but when the conversation turns to music, they snap back into focus.<\/p>\n

Sparks fly in their creative process. With no single leader, they freely exchange ideas and build the music together. \u201cWhen we hear a performance and think, \u2018Why do we sound so bad?\u2019 that\u2019s when the real conversation starts,\u201d Kim said. They insist they don\u2019t have deep, destructive fights, but disagreements are frequent. \u201cWe always argue,\u201d Jeon laughed. Jeong added, \u201cThat\u2019s how good music comes out.\u201d They share a core belief: chamber music is ultimately the process of making a single, unified piece.<\/p>\n

Their SSF program mirrors the trio\u2019s character.<\/p>\n

Arno Babadzhanyan\u2019s Piano Trio in F-sharp minor, third movement, has been on their wish list since they formed. The Armenian composer\u2019s work is considered a peak of Soviet-era chamber music. Its intense emotions and folk-inflected colors demand high-level ensemble skills from all three instruments. \u201cNow is the time to take on this challenge,\u201d Jeong suggested, and the others agreed.<\/p>\n

\"\uc544\ud30c\uc2dc\uc624\ub098\" Kim\u2019s \u201cTango-style Improvisation\u201d appears in the middle of the program. Beginning with percussive cello gestures and unfolding over irregular tango rhythms in which the three instruments converse, the piece is a laboratory for the intuitive instincts of a teenage composer shaped by Piazzolla. They\u2019ll close with the first movement of Paul Schoenfield\u2019s Piano Trio \u201cCaf\u00e9 Music,\u201d a modern chamber gem that fuses classical jazz and klezmer traditions.<\/p>\n

Kim explained, \u201cWe didn\u2019t plan the program from a grand perspective; each of us proposed a piece and the program came together naturally.\u201d Though the works span different eras, regions and styles, they share one thing: none are strictly traditional classical repertoire. \u201cThe big, dramatic gestures in these pieces should help us leave our own imprint,\u201d Kim said.<\/p>\n

\n Kids who left school\u2026 a teenage ensemble\u2019s manifesto\n<\/div>\n

Appassiona represents a new generation in classical music\u2014the classical analogue to the \u201cyoung-creator crews\u201d that have become common in K-pop. These teenagers compose and perform, and they built early visibility through YouTube. Their path diverges from the traditional gifted-music pipeline: YouTube came before competitions. Their individual circumstances reflect shifts in Korea\u2019s classical scene. Two members are homeschooled; Jeon attends an international school. Kim and Jeong are preparing for early admission to the Korea National University of Arts.<\/p>\n

Jeong said, \u201cYou can gain a lot from school, but I realized that staying in school left me little time for practice. Homeschooling offered real benefits, so I left and have never regretted it.\u201d He studies with Kim Young-wook, a member of the Novus Quartet and a professor at the Korea National University of Arts.<\/p>\n

\"\uc544\ud30c\uc2dc\uc624\ub098\" Kim also chose homeschooling with clear intent. \u201cFrom the moment I entered middle school, I felt the three years of high school would be a waste for me,\u201d he said. He acknowledged Yewon\u2019s value\u2014meeting many fellow musicians\u2014but argued that learning from peers often outweighs formal schooling. Watching many Yewon graduates move on to Seoul Arts High School, Kim felt repeating the same three years would be redundant. \u201cAs you advance, you rely less on instruction and more on listening as the best way to study music,\u201d he said.<\/p>\n

Leaving traditional school hasn\u2019t narrowed their horizons. Rooted in classical tradition, they now cross boundaries freely and expand their musical vocabularies. They treat classical music not as a museum piece to be preserved but as a living language to be mixed and extended. Appassiona has written only the first page of that language.<\/p>\n

The three aren\u2019t even old enough for national ID cards yet, and they resist the label \u201cteen prodigies.\u201d \u201cOnce we\u2019re on stage, age doesn\u2019t matter\u2014we\u2019re performers,\u201d Jeong said. Kim said they\u2019d rather hear \u201cThat was a great performance\u201d than \u201cGood for teenagers.\u201d Above all, Jeon said, \u201cMore than being great, we want to make music that\u2019s fun for us.\u201d Free from outside expectations, they\u2019re declaring the intention to make music that belongs to them alone.<\/p>\n","protected":false},"excerpt":{"rendered":"
