Yujung Jung (정유정) is a Seoul-born pianist, keyboardist, composer and teacher who has been based in Boston since she enrolled at Berklee College of Music in January 2008. In 2010 she was named the Mary Lou Williams Women in Jazz Emerging Artist at the Kennedy Center. Before that she was the pianist of a Seoul black-gospel and soul group, and she has also worked as a session keyboardist for K-pop artists, so her story runs through three scenes at once: Korean gospel, Korean pop and American jazz education. No album under her own name has turned up. What can be documented is her stage and teaching career and her recordings as the keyboardist of that gospel group, and this profile says where each source stops.

Her releases and biographies spell the name Yujung Jung; the Kennedy Center, Berklee, All About Jazz and Discogs all use it. The Hangul form 정유정 comes from a Korean listing of the gospel group's band, which names a pianist 정유정, together with All About Jazz's statement that she was that group's pianist. No single page prints both forms side by side.

Background. The Kennedy Center's biography says she was born in Seoul, began piano at six and grew up listening to gospel music. She studied musical performance in Korea and then worked for a media company there. All About Jazz describes her as a graduate of Dongduk Women's University and says she worked as a session keyboardist for many K-pop artists. Its musician page counts more than 1,000 concerts, events and television shows, including MBC's I Am a Singer and Mask Singers and KBS's Sketchbook, and names the Jarasum International Jazz Festival, a concert at the LG Art Center and the 88 Olympic Hall among her stages. These are her own account and none of them is dated.

Heritage of Faith and Heritage. The group she played in began as 믿음의 유산, in English Heritage of Faith, which released its first album, The Brand-Nu Gospel, in September 2003. The release text for its 2012 anniversary edition calls it the first group in Korean CCM to take up black gospel. The Heritage Band that has played with the singers since the group's 2004 Australia tour is described in the notes to the second album, By Faith (December 12, 2005): five players in their mid-twenties who already worked live and in the studio for pop acts, with 정유정 on piano and Fender Rhodes alongside a bassist, an organ and analog synthesizer player, an electric guitarist and a drummer, plus the Asoto Union keyboardist and producer Im Ji-hun (임지훈) on Hammond B-3 and the brass band T.S.T. The same notes say the group had given about 300 live shows since its debut and had played jazz stages including the Jarasum Jazz Festival, an EBS Gonggam concert and a Blue Note date in Seoul. All About Jazz calls her the group's lead pianist and music director and says the ensemble won a Korean Music Award in 2007.

In 2006 the group took the name Heritage for its first release aimed at the pop market, the album Acoustic & Vintage (September 12, 2006): thirteen tracks of soul, funk and gospel played on organ, Fender Rhodes and acoustic piano, with a three-piece horn section led by the brass player Lee Thornburg, arrangements by the keyboardist Greg Mathieson, the bassist Abraham Laboriel, guest parts from the hip-hop artists Dynamic Duo and P-Type, the harmonica player Jeon Jeduk (전제덕) and Im Ji-hun, a mix by Claudio Cueni and mastering by Tom Coyne at Sterling Sound. The album's release text credits her as a co-composer of two tracks: "Mama Song" with the drummer 하형주 and the singer 임효찬, and "Victory Is Mine" with 하형주 and the singer 김효식. At the 2007 Korean Music Awards, held after the album's release, Heritage's "Starlight (feat. P-Type)" won the award for best R&B and soul song, according to the Korean Wikipedia list of winners. The release text names Kim Min-su as that song's composer, and none of the sources itemizes who played piano on it.

Berklee and the Kennedy Center. She arrived at Berklee in January 2008 and studied with JoAnne Brackeen, Cyrus Chestnut and Danilo Pérez, according to the Kennedy Center's biography, which also lists the Performance Division Chair Award and appearances at the Jarasum festival and the Trinidad Steel-Pan Jazz Festival. A Berklee news story from her student years, undated in the copy found, shows her in a faculty-and-student sextet at the Trinidad and Tobago Steelpan and Jazz Festival, one of three students on the trip, who also rehearsed with a small steel band. In 2010 she received the Mary Lou Williams Women in Jazz Emerging Artist honor (Berklee and All About Jazz both give the title; the Kennedy Center's own biography page does not mention it). She later studied at the Berklee Global Jazz Institute under Pérez, according to All About Jazz.

Teaching. All About Jazz's 2023 news item says she became a Berklee ear training professor, the first Korean-born woman in that role, and its musician page adds faculty posts at Howon University and Dongduk Women's University. Berklee's own event pages for her concerts are filed under the Ear Training department. The same news item credits her with sending a former student, Sunny Park, into the Berklee Global Jazz Institute as its first female Korean member, and says she has played the Jarasum festival four times, as a solo pianist and as music director and leader of her own band, and that she was announced for the Panama Jazz Festival in 2024; no festival listing seen confirms the Panama date.

Evidence of Hope. Berklee's concert listings present Evidence of Hope as a set of her original compositions mixed with jazz selections, "blending contemporary jazz with the soul of gospel" and concerned with resilience, healing and joy. A first date, January 27, 2025, at the David Friend Recital Hall, was canceled. A second listing put the program at the Red Room at Cafe 939 on September 4, 2025, with Austin McMahon on drums, Daniel Rosenthal on trumpet, Harold Cui on bass, Yulia Musayelyan on flute and Jung on piano. No recording of the program has been found.

Other credits. Discogs lists a Yujung Jung on keyboards on Cosaan (Nomadic Wax, 2010) by the Boston Senegalese group Lamine Touré and Group Saloum, an album made in the United States and Senegal. The name and the Boston timing fit her years at Berklee, but no other source ties her to the record, so it is listed as a possible credit and not as established.

What is not known. All About Jazz's listing gives a birth date of May 22, 1980, but no second source confirms it, so the header gives the birthplace only. No interview, no recording under her own name and no free photograph has been found. The Kennedy Center says she produced three albums with her gospel band and All About Jazz says four; the sources found document two Heritage albums with her in the band, By Faith and Acoustic & Vintage, and the group's first album of 2003 predates the band described in the notes. She appears to be alive and active, with her latest dated concert listing in September 2025.

She has not published a statement of influences. Her teachers at Berklee included Brackeen, Chestnut and Pérez, and the descriptions of her work agree on a blend: Berklee calls her program contemporary jazz with the soul of gospel, All About Jazz speaks of her fusing jazz, gospel and K-pop, and says hidden K-pop undertones run through her original music. Her own stated aim, in the Kennedy Center's biography, is to share her faith through music and to help gifted students who cannot afford piano study. The recordings that can be heard are not jazz records: Heritage's albums are filed under CCM and religious music, R&B and soul on Bugs and under funk, soul, R&B, K-pop and gospel on Discogs, and her part in them is as a band keyboardist and co-composer. The jazz side of her identity rests on her Berklee training, the Mary Lou Williams honor, festival bookings and her concert program, not on a jazz album. The Subgenres above come from her own and Berklee's description of the music; they are an approximation.
