Kim Jong-seo Reveals the Secret Behind His Enduring High Notes in a Candid Talk With Sung Si-kyung

Singer Kim Jong-seo, often described as a 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 Eardrum Boyfriend, he calmly explained how he has preserved his unmistakable vocal tone over many years and how he manages himself as an artist.

His remarks offered a candid look at the work required to maintain a voice that has long set him apart. Rather than treating vocal ability as something that can simply be taken for granted, Kim described an approach built on consistent attention and disciplined self-management.

A Strict Approach to the Voice as an Instrument

Kim Jong-seo suggested that a singer's voice is more than a part of the body: it is the artist's most important instrument. In discussing the practical self-care measures he follows in everyday life, he showed how maintaining his enduring high notes and distinctive tone is directly connected to preserving his vitality as a musician.

For Kim, caring for his voice is therefore not merely a technical task. It is an ongoing process that allows him to continue making music and performing with the qualities that audiences have associated with him throughout his career.

He also displayed the careful attention he gives to regulating the condition of his voice. As a vocalist who must release explosive energy onstage, his routine for remaining in peak condition reflects the musical pride he has upheld over a long period of time.

That disciplined routine illustrates the effort behind the powerful performances seen by audiences. His consistency is supported by close attention to his condition and by an attitude that regards preparation as an essential part of life as a vocalist.

A Moment of Musical Connection With Sung Si-kyung

The appearance became even more meaningful through Kim Jong-seo's meeting with host and fellow artist Sung Si-kyung. The two respected each other's musical worlds and carried on an in-depth conversation rooted in experiences that people who work with the voice could understand.

Their sincere exchange naturally revealed some of the concerns and hard work that remain hidden behind a polished stage performance. By focusing on the responsibility involved in caring for the voice, the conversation brought the less visible side of an artist's craft into view.

Junior artists Taemin, Jaehyun and Haechan were also present, creating a musical connection across generations. Kim's rigorous self-management offered them more than simple advice: it provided an opportunity to reconsider the attitude required to reach the highest level in a chosen field.

The sincerity Kim Jong-seo showed toward his voice went beyond technical maintenance and reflected his deeply respectful approach to music itself. The conversation underscored how those efforts, accumulated steadily over time, have helped establish the distinctive position he holds today.
