Rami’s vocal range spans approximately A3 to E5, with a mezzo-soprano instrument that sits at the border between warm alto depth and bright upper-register power. Born Shin Haram on October 17, 2007 in Jungnang-gu, Seoul, South Korea, she debuted with YG Entertainment’s girl group BABYMONSTER in November 2023 at age 16 — following six years of intensive training that began when she was cast at YG in 2018. During the group’s pre-debut reality show, Korean singer and judge Lee Mu Jin praised her specifically, noting she “has a bit of a Celine Dion vibe” and that she “controls the song wonderfully, providing a clear sense of the beginning, middle, and end of a story.”
She was admitted to Hallym Entertainment Arts High School as a top student in the Practical Music department. She is the main vocalist of BABYMONSTER, occupying the role of primary melodic carrier in a seven-member group — a designation that signals both the highest technical vocal capability and the most musically exposed position in the group’s performance structure.
Rami’s Vocal Range at a Glance
Vocal range: approximately A3 – E5 (estimated from performance context) Voice type: Mezzo-soprano (with alto-adjacent warmth in lower register) Vocal registers in use: Chest voice, mixed voice, head voice Approximate span: Around 2 octaves in primary working range Group position: Main vocalist, BABYMONSTER YG lineage cited: Taeyang, Park Bom, Kang Seungyoon, Rosé
What Voice Type Is Rami?
Multiple analyses describe Rami’s voice as sitting at the mezzo-soprano and alto border — warmer and darker in the lower register than a light soprano, but with the upper-register access that keeps her clearly in the mezzo category rather than the true contralto. The vocal analysis circulating in K-pop communities notes: “If we listen to her lower register, she shows a warmer tone that is similar to an alto. Her ability to effortlessly handle higher notes could also make us consider her a mezzo-soprano.”
The Celine Dion comparison Lee Mu Jin offered is telling in terms of voice type context — Dion is a soprano/mezzo-soprano with exceptional power and emotional directness in the belt zone, which aligns with what Rami demonstrates in her pre-debut and early debut performances.
The NamuWiki profile describes her as possessing “excellent vocal technique, stable vocalization, accurate pitch control, powerful voice, ability to control speed, wide vocal range” — all professional-level assessments for a 16-year-old at debut. YG specifically describes her as following in the lineage of their previous vocal standouts: Taeyang, Park Bom, Kang Seungyoon, and Rosé.

Her Lower Register: Warmth and Emotional Presence
The warmth in Rami’s lower register — what analysts compare to an alto’s depth — is the quality that made her pre-debut performance of Mario’s “Let Me Love You” circulate so widely. At 15, performing a soulful cover over a piano accompaniment with no staging or production support, the lower chest voice carried emotional weight that reviewers described as “hard to believe for a 15-year-old.” The “soulful tone on a calm piano melody” described in the KbizOOM profile is the lower-register chest voice functioning as the primary emotional carrier.
This quality — lower chest voice resonance that conveys feeling rather than simply demonstrating pitch — is precisely the technical marker of a well-developed mezzo instrument. It’s also the hardest quality to train, because it requires both technical support and the interpretive maturity to deploy it appropriately.
Her Upper Register: Power and Precision
The upper end of Rami’s range demonstrates the other side of the mezzo instrument: power in the belt zone and access to the upper register with “accurate pitch control” even under live performance conditions. K-pop idol training places very specific demands on the upper register — idol performances combine singing with intensive choreography, which means the upper register has to function under physical exertion, not just in a stationary studio context.
Her admission to Hallym Entertainment Arts High School as top student in Practical Music confirms that the voice was already assessed at a professional level before YG’s six years of training began to compound that natural capability.

Six Years of YG Training: What It Built
Rami began training at YG Entertainment in 2018 at age 10 or 11 — before she had any foundation in dance. The NamuWiki profile notes: “Originally, it was my first time dancing so I didn’t even have the basic skills, but I said that I rented a practice room near my house every day off and practiced for 9 to 10 hours a day.”
This account of self-driven supplementary training — renting a practice room independently to supplement what YG provided — is a specific biographical detail that speaks to the work ethic behind the voice. YG Entertainment’s training system produces technically accomplished vocalists; what distinguishes standouts within that system is the additional self-directed development that comes from internal drive rather than institutional requirement.
Her cover of “Let Me Love You” was filmed by YG and released publicly before her debut — a deliberate showcase of the main vocalist’s voice before the group’s commercial launch. YG’s choice to present her voice in a stripped-back, unproduced format reflects confidence in the instrument’s standalone quality without production support.
BABYMONSTER: Group Context
BABYMONSTER debuted in November 2023 with “Batter Up” — a dense, high-energy track that places the group’s vocalists under maximum pressure in terms of pitch accuracy while performing synchronized choreography. Rami’s role as main vocalist means she carries the melodic peaks and the most exposed passages across the group’s repertoire.
The group operates within YG Entertainment’s signature house sound — the label that produced BLACKPINK, Big Bang, and WINNER — which emphasises vocal power and performance intensity alongside choreographic precision. Rami’s instrument, which combines warmth in the lower register with power in the upper, fits this aesthetic precisely.
