Are you a pianist who loves K-Pop? If so, this is one release you won’t want to miss. HYBE recently launched official piano arrangements of songs by its artists, and today we’ll take a closer look at one of them—ENHYPEN’s〈Fatal Trouble〉. In this article, we’ll explore the musical structure and key characteristics of the song, along with an in-depth review of its newly released official piano sheet music.
ENHYPEN’s “Fatal Trouble”: Dark Fantasy in Motion
ENHYPEN’s “Fatal Trouble” music video was officially released on May 13, 2024, via the group’s official YouTube channel. Presented in an animated format, the video unfolds the narrative of the vampire boys from the DARK MOON series, adding a strong sense of fantasy and storytelling.
As of now, the official music video has surpassed 17.7 million views, drawing significant attention from fans worldwide. Streaming clips and performance videos continue to circulate actively among fans, and the group’s highly demanding, tightly synchronized choreography—often described as “knife-like precision”—has been a major talking point.
ENHYPEN’s global fandom, known as ENGENE, had already amassed over a million followers on social media even before the group’s debut. Since then, the fandom has continued to grow through album releases, world tours, and live performances
Who Is ENHYPEN?
ENHYPEN is a seven-member boy group consisting of Jungwon, Heeseung, Jay, Jake, Sunghoon, Sunoo, and Ni-ki. The group debuted in 2020 through the survival program I-LAND and quickly established themselves as one of the leading acts in K-Pop. By combining music, performance, and a well-developed narrative universe, ENHYPEN has earned widespread recognition and love from fans both in Korea and internationally.
An Unsettling Opening: Mystery Chords and Harmonic Ambiguity
The song opens with a striking progression of GM–EbM–Gm–CM, a sequence that immediately obscures any clear sense of key and creates a strong feeling of tension. This mysterious chord progression reappears in the pre-chorus after the verse, further intensifying the sense of unease.
In contrast, the chorus shifts to Gm–EbM–BbM–DM, a progression with a much stronger tonal center. These chords repeat throughout the chorus, culminating in an explosive surge of energy at its conclusion.
By alternating between ambiguous, “mysterious” harmonies and more conventional chord progressions, the song reinforces the emotional push and pull of the lyrics—oscillating between anxiety and longing. Thanks to this compelling structure and sound design, 〈Fatal Trouble〉 lingers in the listener’s mind long after the song ends. Even in 2026, two years after its release, it remains a fan-favorite, further elevated by ENHYPEN’s powerful performances.
HYBE’s Official Piano Arrangement of 〈Fatal Trouble〉
Building on the original song’s structure and emotional depth, HYBE’s official piano arrangement of 〈Fatal Trouble〉 is designed at an intermediate difficulty level, making it well-balanced and accessible for hobbyist pianists. The score also includes a QR code that links to a performance video, which can be especially helpful as a reference before practicing.
Rather than attempting to replicate every layer of the original production, the arrangement focuses on capturing the song’s core atmosphere, motifs, and melodies. Through repeated rhythmic patterns and bass-driven motion, it preserves the original tension while effectively utilizing the piano’s tonal qualities to translate the song into an idiomatic keyboard work.
Musical Focus: Rhythm, Dynamics, and Pedaling
Overall, this arrangement prioritizes rhythmic stability, dynamic control, and thoughtful pedaling over flashy virtuosity. This allows pianists to concentrate on shaping the mood and emotional nuance of the piece. For subscribers looking for official K-Pop piano scores—or for those seeking a slightly darker-toned piano repertoire—this arrangement offers plenty of musical enjoyment.
Translating Tension from Track to Keyboard
In the piano version, the left hand primarily outlines the accompaniment and rhythmic foundation, while the right hand carries the melody, creating a clear division of roles. The intro retains the original mystery chords—GM–EbM–Gm–C—and the intentionally dissonant clashes between the hands become even more striking when rendered through the piano’s timbre.
In the verse, the left-hand accompaniment features relatively large leaps, requiring careful attention to hand movement to avoid missed notes. The rap sections are notated with triplet rhythms that closely mirror the original groove, layered against steady eighth-note motion in the left hand. This creates a complex mixed-rhythm texture, demanding rhythmic independence both within each hand and between the hands.
Chorus Overlap and Changes in Arrangement
The first measure of the chorus begins simultaneously with the end of the pre-chorus melody—an example of overlap. To ensure smooth execution, this overlapping passage is written as a simple single-line melody in the right hand, with minimal leaps.
In contrast to the intro and verse, the chorus features a noticeably different arrangement. The right-hand melody, previously presented as a single line, expands into parallel sixths, heightening the dramatic impact. Correspondingly, the left hand reinforces the bass by adding octaves on the downbeat of each measure, enriching the overall sound. These subtle shifts in arrangement add variety and keep the practice process engaging.
Bridge and Outro: Building Toward the Climax
In the bridge and outro, octave unisons extend into the right hand as well, significantly amplifying the song’s tension and dramatic effect. The density of the texture increases naturally, making the climax of the piece more pronounced. As the melody spans a wide range of the keyboard, this section becomes both a compelling listening highlight and a technical focus point, requiring careful control of hand movement and tone production.
