Kim Jong-seo Reveals How He Preserves His High Notes in a Candid Talk with Sung Si-kyung

Singer Kim Jong-seo, often described as the voice of his era, has opened up about the demanding effort he makes to sustain his musical longevity. Appearing on the music program “The Seasons—Sung Si-kyung’s Gomak Namchin,” he calmly explained how he has preserved his unmistakable vocal tone over many years and how he manages himself as an artist.

A rigorous approach to the instrument of the voice

Kim suggested that, for a singer, the voice is far more than merely one part of the body: it is the artist’s most important instrument. His remarks framed vocal care as an essential part of the work itself, rather than something separate from performing or making music.

He spoke about the specific self-care practices he follows in everyday life to retain both his unwavering high notes and the distinctive tone associated with his singing. Through that account, Kim showed that caring for his voice is inseparable from the continuing process of protecting and extending his life in music.

Kim also displayed the meticulous attention he gives to regulating the condition of his voice. That careful attitude reflects an awareness that an instrument used continuously over many years must be observed and managed with discipline if it is to remain dependable.

As a vocalist who must release explosive energy onstage, maintaining his best possible condition requires a consistent routine. The practices he has upheld are closely connected to the musical pride he has carried throughout his career, revealing how seriously he approaches the responsibility of continuing to perform at a high level.

A moment of musical connection with Sung Si-kyung

The appearance became even more meaningful through Kim’s meeting with the program’s host, Sung Si-kyung. With each artist showing respect for the other’s musical world, they continued an in-depth conversation rooted in experiences that people who work with the voice could understand and share.

Their candid exchange naturally brought attention to the struggle and effort that remain hidden behind the brilliance of the stage. Rather than focusing only on the finished performance heard by an audience, the conversation illuminated the sustained discipline that allows an artist to keep delivering that performance over time.

Junior artists Taemin, Jaehyun and Haechan were also present, creating a musical connection that reached across generations. Their participation placed Kim’s reflections in a setting where the experience of a senior singer could be encountered directly by younger performers.

The thorough self-management demonstrated by Kim offered those junior artists more than simple advice. It provided an opportunity to reconsider the attitude and level of commitment required to reach the summit of a chosen field—and to remain there through continued effort.

Kim’s sincerity toward his voice ultimately went beyond technical maintenance. It reflected a reverent approach to music itself, showing that vocal discipline, artistic pride and respect for the craft are deeply intertwined in the way he has sustained his work.

The appearance also made clear that his unique standing today was not created in a single moment. It was built through layer upon layer of effort, accumulated over many years as he continued to protect his voice, preserve his distinctive sound and devote himself to music with unwavering seriousness.
