Voice Type

Light Lyric Soprano

Strengths/Achievements Able to support her voice properly within 1 octave of range Notes on A3 and above carry support and are nicely connected Notes above Bb4/B4 can at times carry some support, up until C5 Able to sing smoothly with good pitch most of the time Voice is able to connect with a healthy head voice at times Lightly mixes, so less damage is brought to her voice when she is out of her supported range Vibrato can be produced with a healthy technique Weaknesses Throat closes easily on notes outside of her supported range Unable to create more dynamics and different volumes/onsets with her voice Notes above B4 generally are tight and the larynx goes high Her low notes below A3 lack support, connection and projection Nasality is often present in her voice, she can get quite whiny at times Voice lacks agility and accuracy in pitch when trying more complex vocal lines B4’s and other belts can get constricted, mostly on the 오 (Oh) and 우 (Oo) vowels Falsetto is tight, weak and overly airy Registers Lower register: Generally supported down to A3, with nice enough projection and enough support to connect the voice. Lower notes lack projection and sound shaky. Mixed register: Higher mixed range above C5 becomes tight and overly light, with little support. Notes on B4 and below are generally relaxed and supported, able to at times create fuller supported B4’s and Bb4’s, but many times nasality is present in the voice. Upper register: Falsetto is generally used the higher she goes but in a range that’s comfortable and in her supported range, she can lighten up her mix and create a pure head voice. Most other times, although able to extend her falsetto high, it stays tight and tense. Agility

Possessing a light girly voice, Jieun lacks in the flexibility department. The voice is not only not ready to do vocal runs, she seems to, for the most part, be aware that she does not have the necessary agility to properly deliver ornamentations in songs. The few times where she was required to do more complex vocal runs in her performances include “희망고문“, where her runs were frequent during the whole of the song but lacked in terms of connection, precision and separation of pitch, sounding sloppy, inaccurate and quite slow. Another case would be her performance of “꿈” where even with the help of consonants to ease the transitions, her adlibs and scoops or slides lacked precision and flexibility.

Overall analysis

One of Korea’s debutants on Immortal Song, Jieun was able to showcase her vocal skills first through her debut in Secret, then later through Immortal Song 2 and lastly through her solo debut. Her voice is very girly, almost angelic, with a very delicate quality and would most likely fall under the light lyric soprano fach.

On the low extreme of her range, Jieun has one good ad
