Dr. Hyejin Cho enjoys a flourishing career as a soloist and chamber musician, performing in concerts across the U.S., Europe, and Asia. Her passion for Robert Schumann led her to develop a concert series featuring his piano works, which she has successfully established in eight different states with support from the Missouri Arts Council, the Kate Neal Kinley Memorial Fellowship, the University of Michigan Research Grant, and OMF Music Resources. Her Schumann performances and interviews have been broadcast worldwide on Parma Recordings Live Stage and featured nationally and regionally through outlets such as the Dame Myra Hess Concert Series on WFMT 98.7FM, the Wheaton College Artist Series: Emerging Artists Showcase, KOPN Columbia 89.5FM, KUCO Edmond-Oklahoma City, the International Music Foundation YouTube channel, and the Sheldon Concert Hall YouTube channel, among others. As a concerto soloist, Cho has performed with numerous orchestras both nationally and internationally. Her appearances include Beethoven's Fourth Piano Concerto with the Ann Arbor Symphony Orchestra in the United States and the ChunCheon City Youth Symphony Orchestra in Korea, Mozart's Piano Concertos K. 451 and K. 488 with the Northern Illinois Chamber Orchestra across five cities in northern Illinois, and Chopin's Second Piano Concerto with the Ewha Womans University Orchestra in Korea.

In addition, Cho is developing projects to promote the works of female composers, with the goal of creating an equal platform for their works. Her research focuses on composers such as Cécile Chaminade, Fanny Mendelssohn-Hensel, Madeline Dring, and Vivian Fine, whose works she has performed in public concerts since the 2021–22 season. This includes a recording of Vivian Fine's chamber works, released on Albany Records. Inspired by her research on Fanny Mendelssohn-Hensel, she launched a project titled ‘The Mendelssohns,’ celebrating Fanny’s unique musical voice while showcasing the Mendelssohn style of the siblings, with a focus on the Easter Sonata for Piano—a masterpiece lost for over 150 years and once mistakenly attributed to Felix.

Alongside her solo career, Cho is deeply passionate about chamber music and has extensive experience in collaborative performances. She is a founding member of the American Prize-winning Koinonia Piano Trio, a performing and teaching ensemble that has toured New York, Florida, Illinois, Michigan, Missouri, Minnesota, Alaska, and five cities in Europe as part of a tour through Austria, Germany, and Italy. As a vibrant and service-minded ensemble, the trio has established several performance residencies and has given outreach concerts and workshops. The trio has received numerous grants, including a $10,000 Binkow Grant for their European tour.

In addition, Cho has collaborated with artists such as Gilles Apap, Danielle Belen, Aaron Berofsky, Maximilian Dimoff, Arianna Dotto, Nathan Giem, David Halen, Chee-Yun Kim, Jonathan Ruck, Yizhak Schotten, and members of the Cleveland Orchestra, St. Louis Symphony Orchestra, Ann Arbor Symphony Orchestra, Lansing Symphony Orchestra, and the Calidore String Quartet, among others. Her passion for collaboration has also led her to participate in numerous music festivals, including the Innsbrook Institute, Maui Classical Music Festival, Brightmusic Summer Festival, Anchorage Chamber Music Festival, and Ann Arbor Chamber Fest.

An enthusiastic educator, Cho currently serves on the piano faculty at Wheaton College Conservatory of Music, where she teaches applied piano lessons, piano ensemble, and piano chamber music. She previously held teaching positions at Oklahoma State University, the University of Michigan, Blue Lake Fine Arts Camp, Anchorage Chamber Music Festival, among others. Additionally, she has worked closely with collegiate-level students, offering lectures, masterclasses, and performances at institutions including Oberlin Conservatory of Music, the University of Utah, the University of Missouri, the University of Minnesota Duluth, the University of Oklahoma, the University of South Alabama, Northern Illinois University, Truman State University, the University of Central Oklahoma, and Oklahoma Baptist University.

Cho is also an active member and presenter of the Music Teachers National Association and the College Music Society. She is a Nationally Certified Teacher of Music, granted by MTNA. From 2022 to 2024, she served on the board of the Oklahoma Music Teachers Association as Collegiate Chapter Chair, where she created and organized the OMTA collegiate poster session, which has been successfully presented at the OMTA State Conference since 2023. Furthermore, Cho's research and projects have been featured at national and regional conferences. Her lecture recital, titled "French Female Pianist-Composer Cécile Chaminade's Strategies to Succeed in American Musical Culture Between 1890-1920, Reflected in Programmatic Character Pieces for Solo Piano," and her paper presentation, "What Makes Robert Schumann Schumann: Schumann's Creation of Fantasy Borrowed from Literature, Especially E. T. A. Hoffmann's Novel The Life and Opinions of Tomcat Murr," were both presented at the CMS South Regional Conference. Additionally, she performed at the CMS National Conference in the session titled "Milhaud's Musical Response to the 1918 Pandemic."

A strong advocate for community engagement, Cho and Dr. Jun-Hee Han co-founded the Lucerna Music Foundation, a non-profit organization dedicated to providing high-quality music education and performances to communities with limited access to the arts. They have performed extensively in Freeport, Illinois, through the Freeport Community Concert Series and the Freeport Art Museum, experiences that helped them recognize the community's need for access to the arts. They are now committed to giving back as pianists and educators. Their journey began with a performance for 350 young students at Blackhawk Elementary School in Freeport, an event that inspired their vision to expand this project to reach more communities. With a mission to bring classical music and education to underserved areas, they aim to inspire and enrich lives in Northwest Illinois and beyond.

Originally from Seoul, Korea, Cho graduated with Summa Cum Laude honors and as valedictorian from Ewha Women’s University with a Bachelor of Music in Piano, earning a full scholarship. After graduation, she came to the United States, studying with Menahem Pressler at Indiana University and earning a Master of Music and an Artist Diploma in Piano. Cho completed a Doctor of Musical Arts degree in Piano Performance at the University of Michigan under Christopher Harding, concurrently pursuing a Master’s degree in Chamber Music under Amy I-Lin Cheng, Christopher Harding, Martin Katz, and David Halen, all while on a full scholarship. Additional studies include private piano study with Wonmi Kim in Italy, fortepiano with Eunji Lee at Indiana University, and harpsichord with Dawn Kalis at Indiana University.
