E3 ~ Bb5 (2 octaves and 3 notes)
B3 ~ D5/Eb5
- Resonance up to C5/C#5 frequently
- Adequate support is carried up to D5/Eb5
- Decent agility with runs being mostly accurate with decent separation in between pitches
- Good intonation is kept within her supported range, rarely goes off
- Though excessively airy, her falsetto is normally relaxed and not tight in the throat even on A5
- Knows her voice well enough to know that her lower register is underdeveloped, so she rarely uses it
- Has enough musicianship to make songs her own
- Most underdeveloped lower register in KPOP, her lower register really is pure air. The melodic line of “I Dream” had to be used to identify her E3 because it was that airy
- Though relaxed up to A5 her falsetto, like her lower register is extremely airy, though not as bad as her lower register.
- Before she debuted her chest voice had less air
- Follows JYP’s “Half Air Half Sound” technique which is probably why her lower register, falsetto, and chest voice are airy.
- Only developed register she has is her middle register
- Can be slightly nasal at times
- Though her mix register is fairly developed, notes above Eb5 present a lot of tension and lack proper tonality
- Wobbly vibrato at times causing her to sound unstable
- Uneven breathing
- Lower register: The most underdeveloped lower register in KPOP. Below B3 her voice is simply isn’t supported at all. The best way to describe her lower register really is ‘pure-air’ because that really is what it is. Her lower register lacks so much tone that the actual melodic line of the song she is singing has to be used to identify low notes.
- Mixed register: Her most developed and solid register. Solid support up to Eb5 and resonance up to C5/C#. Though her mixed register is developed resonance is only carried up to C5/C#5, but not up D5/Eb5 this is mainly because her throat isn’t as opened or relaxed as it is in the C5/C#5 area. It is unknown how well she does on E5 as she has never done an E5 live nor in studio, but she has demonstrated notes in the F5-G#5 range. In the F5-G#5 range YeRin’s voice becomes small and pushed, in her cover of Ariana Grande’s “Problem” her G#5 is quite literally a squeak; it was very squeezed and pushed out of her throat.
- Upper register: Though relaxed up to A5 it doesn’t change the fact that it is excessively airy. Her falsetto almost mirrors her lower register in terms of production; airy. However she has more control and vocal cord connection at least up to F#5, above that her falsetto really is airy and lacks vocal cord connection. Even though her falsetto is airy, transitions done into it aren’t bad, there aren’t any true breaks but the connection in the vocal cords in her falsetto still isn’t there. Surprisingly, she has enough control in her falsetto to actually be able to pull off decent vocal runs within it. Though obvious, she has not shown true head voice unlike JiMin.
Considering her age YeRin has surprisingly good agility especially compared to older idols. Her runs tend to be done with mostly accurate intonation, meaning she has good control over what she is doing and knows pretty much where every note is going and where it sits within her voice, which is key to a good vocal run. There is also good separation between the pitches in her runs, which means her runs have flow and they aren’t overly slow. She also maintains a good speed throughout her runs. For demonstration of her runs check her performance of “Love”.
Even though YeRin is only 17, she has a great understanding of music and of her own voice. She also has a better mix and more agility than many of her seniors and the so called “Vocal Goddesses and Gods” of K-POP. That being said I am greatly sad that she and JiMin were exposed to the ‘Half air, Half sound’ technique. Whereas JiMin has thoroughly ignored the bogus technique, YeRin has actually applied the technique to her singing, because of this YeRin, in the chest voice, falsetto, and lower register, is excessively airy. Fortunately though, her middle register has been left untouched by this bogus technique. The reason why the ‘Half air, Half sound’ technique is bogus is because it teaches the vocalist that airy and breathy vocals are OK when it is not. Airy and Breathy vocals prevent true desirable tonality to be achieved because the vocal cords are not fully coming into contact with each other, as well as it can also leading to vocal damage, which may result in vocal nodules.
In the past, YeRin’s chest voice had much more solidity and weight to it, meaning more vocal cord connection in that area, however after being taught JYP’s ‘Half air, half sound’ the fullness and connection of the vocal cords in her chest voice disappeared and was replaced with an airy tone. Even as a child YeRin had pretty solid technique in the middle register resonating B4s at the age of 10 in her performance of Beyonce’s ‘Listen’ for her JYP audition and on Star King. Comparing her lower register from when she was younger and now, it hasn’t improved much, if at all. It is just as airy and unsupported as it was 7-8 years ago but she was more confident in using it hitting F#3s in her “Listen” cover.
YeRin’s greatest strength lies within her middle voice which is fairly well trained and developed. YeRin supports herself up to Eb5 and up to resonates C5/C#5 often. Though she is resonant up to C5/C#5, her resonance is not very large because she does not manipulate her vocal tract to its fullest potential or isn’t 100% relaxed. She isn’t resonant up to her highest supported note because she isn’t 100% relaxed in her throat. Outside of her supported range in the middle she becomes very weak with notes outside of it, being very pushed, squeaked and strained, making her voice sound extremely small. This has been demonstrated especially in her cover of “Problem” by Ariana Grande where she pretty much squeaked the F#5 and G#5. It has been stated that her supported range goes up to Eb5, but it is unknown how she does on E5 because she has yet to do one live or in studio. There are also times that her vibrato is wobbly making her sound unstable.
Another strength of YeRin’s would be a generally relaxed falsetto even a semitone away from her highest note. Though airy, she is still able to keep a fairly relaxed falsetto up to A5. She has demonstrated this many times while preforming “Sugar”. She’s also able to do pitch accurate and decently spaced out runs in her falsetto. Switching into falsetto seems to not be a problem for her as no noticeable breaks are apparent when she does so.
Her lower register needs the most care into further development. Her voice only has true tonality down to B3/C4 which, for a Soprano voice, is nothing since those aren’t even really classified as low notes for them. Her cord connection in the lower register is pretty much nonexistent, there is almost no sound down there at all. The only time she has any type of sound in the lower register is when she lower larynx to create an artificial “big” sound and a lowered larynx low note is just as bad as an airy one; both are unsupported. Judging from some of the songs she has sung, YeRin knows she has a bad lower register or at least knows she is uncomfortable down there. It is a good thing that she knows that she isn’t very skilled down there, but she doesn’t try to improve on her fault, which defeats the point of you knowing you have a fault. She would easily be a Competent or a Competent to Good vocalist if her lower register were to improve to at least an average level or her falsetto were to get more cord connection.
Very good musicianship. One of her influences is Whitney Houston, who was known for a immense amount musicianship, so it was almost a given she would have musicianship. Her style is heavily set in R&B; she loves doing fast runs and quick triplets majority of them being very well executed with proper tonality, separation and accuracy. She tends to change the keys and melodies of songs to suit her voice and style. While preforming Beyonce’s “Halo” she changed the C#3 to an A3. She also changed the low notes of other songs on various occasions. She also ha a very great ear for harmony as she frequently harmonizes with JiMin.
