Apink’s Vocal Analysis: Jung Eunji [Newly Updated]

Vocal Range

Bb2 ~ C7 (4 octaves and 1 note)

Supported Range

G3/G#3 ~ C#5/D5

Voice Type



  • Very well trained and consistent mixed register often carrying resonance up to C#5/D5
  • Support can sometimes be carried up to Eb5/E5
  • Knows to lighten her mix the higher she goes
  • Very well placed sound in the mix and lower register
  • Normally sings with a risen soft palate
  • Very smooth legato singing
  • Very well placed and rounded resonance on C5/C#5
  • No weak registers
  • Can maintain tone down to C#3
  • relaxed falsetto up to E5/F5

Points for Improvement

  • Mix can get too heady at times losing projection
  • Notes above Eb5/E5 are constricted with a slightly risen larynx
  • On the ‘aye’ vowel sound (애 and 에) her throat tends to close
  • Mixing technique seems to have declined a bit since debut
  • When runs are attempted they come out messy and inaccurate


  • Lower register:  Eunji’s lower register is fairly well trained and connected to the rest of her voice. She’s capable of maintaining a neutral larynx and supported sound down to G3/G#3 and maintaining tone done to C#3, however notes below G3 lack true projection and support.
  • Mixed register: Definitely Eunji’s most well trained and consistent registers. She’s capable of keeping a supported and resonant sound up to C#5/D5 and occasionally up to Eb5/ E5.  She finds the most resonance around the C5/C#5 range.  Notes above Eb5, including E5, have a more constricted and small sound due to her not truly supporting and keeping her throat open.
  • Upper register: The weakest and least explored register in performances. Eunji has an extremely extensive upper register being able to go all the up to an A6. However, even though she has an extensive head register, she doesn’t really use it in performance singing normally maxing out at G5. She also doesn’t use a true head voice normally using a relaxed falsetto.


Even though EunJi has a lyric voice when she attempts to sing runs and melisma of any kind they don’t normally come with a smooth fluid sound and pitch can be off. However she rarely incorporates runs and melisma in her performances so this problem is normally avoided.

Overall analysis

Eunji has been turning heads in Korea with her rich and full voice ever since her debut as Apink’s Main Vocalist in 2011. Eunji quickly made a name for herself as a vocalist with the fact that her voice was well showcased in Apink’s songs. She quickly became known as the vocal “powerhouse” of the group.

As main vocalist of Apink, Eunji is responsible for managing the high notes and carrying the group the most vocally and she is the definitely the member most qualified for this job. With a supported range of G3/G#3 ~ C#5/D5 great resonance in the A4 ~ D5 and a considerable amount of ease in the lower register she definitely sets herself apart from the other members of Apink. Not to mention her rich, full, womanly tone is also a great ear catcher.

Eunji has said she wishes to become a vocal trainer after her days as an idol as over which, judging by her technique, definitely is a plausible and reasonable ambition. She definitely has the vocal skill to be able to teach a student how to sing correctly to an extent.

Eunji’s mix is her most developed and consistent register. She is quite consistently capable of supporting in the C#5/D5 range and resonating there as well. She can also occasionally bring up support to E5 for example her performance of “When I First Saw You” with Yang YoSeob of B2ST.  Unlike most sopranos EunJi begins to lighten up her mix around C#5/D5 which is most likely where a mezzo begins to lighten her mix. Eunji is no doubt a soprano though, but this is alright because majority of the time she still projects properly and resonates. That being said, she still has times where she lets the head to chest ratio lean too much into the head side, making her lose projection. For example the D5  right before the E5 in “When I First Saw You.”  Even though the note is still supported, it did not have much projection because she allowed too much head voice into her mix. The E5 proceeding the D5 is actually heady as well, but she pulled the sound forward into the head and balanced out the mixing more so the projection was still there. Eunji definitely has the most resonance and ease in the B4 ~ C5/C#5 range. Notes in this range are quite consistently projected properly with a healthy and even vibrato. For example her performance of Listen from Apink’s first concert. She stays pretty consistently around the B4 ~ C5/C#5 area and handled it very well having a strong powerful vibrato for majority of the notes, good support and placement. Eunji above Eb5 does have bad moments than good especially about E5. Approaching more of the E5/F5 are she has trouble keeping her throat open especially on the ‘aye’ vowels and ‘oh’ 에,애 and 오 in Korean.  This is best showcased in her performance of ” 미워요”(I Hate You) on Masked singer.  Throughout this performance she does many E5s and F5s all of which are done with a fairly high larynx. There other examples of this like in Apink’s main title songs ex: My My. Even though the larynx is high and the throat is tight her attempt on notes above E5 are better than most because she mixing is lighter and brighter with better placement.

Despite being a soprano, Eunji has surprising comfort in her lower register.  Unlike many sopranos who tend to have weak, weightless, and airy tones in the lower register, Eunji is able to maintain a fairly solid sound with a decent amount of weight. She also seems to have no problem with phrasing low notes and going to the bottom of her lower register which she has demonstrate in hercover of “Goose’s Dream.” In this performance she sings below F3 quite frequently and still maintains a decent amount of tone maxing out at C#3.  Despite her easily being able to sing down to her lowest note, she best supports her voice in the G3/G#3 range, which for a Soprano according to the set criteria isn’t too bad.

EunJi’s head register is definitely the least explored register of her voice normally not singing very high notes in it unless she has to, like the Bb5 in “Run To You.” Eunji normally stays in the lower to upper 5th octave when using this register mainly for what seems to be stylistic purposes. This register of hers is definitely very extensive as it expands all the way to Soprano A (A6), which she demonstrated in Apink’s High Note battle. Despite all of the range she has in this register, she doesn’t support it, instead she mainly uses only a falsetto and that only has a relaxed sound up to E5/F5. Above that, she can be overly airy and tense, such as the descending run from D6 down to F5 from “Boom Pow Love.” More recently she’s shown that she can extend her falsetto range as high as C7, as heard in “Emotions.”


Eunji, like most ballad centered vocalists, focuses a lot more on the phrasing and dynamic aspect of singing more so than the pure technique part of it. She definitely colors her singing with airy vocals and soft dynamics that she can build upon within a song. She also loves to incorporate many high notes into her singing, which is something she is very well known for.  She isn’t one to color songs with runs probably because she isn’t confident while doing them.

    1. She sounds shallow, she is not allowing a strong enough stretch of her vocal cords without relying mostly on air. She was singing in falsetto so there was little room to strain.


  1. Hey Ahmin,
    I’ve been visiting this site since i first knew it! And I’ve learnt a lot from it, thanks to you guys, you are amazing 🙂
    Finally, I’ve recorded something 😀
    NoNoNo- Apink

    Wish you answer all these questions:
    1- Any support? Where do i lose it? ((I can go down to D2 and up to E4 (without head voice) but I don’t know my support range))
    2- Any resonance?
    3- Good placement?
    4- Vocal type? (16 Years old, IDK if that makes differece)
    5- How can I improve?
    6- Any other notes?


    Waiting for your reply so bad,
    George A.


    1. Oh hi dear. Thank you so much, you’re so sweet! Okay I’m going to have to tell you what I tell many young boys. Singing an uptempo girl group song is not a productive way of showing your singing nor of practicing singing. It’s fun and you’re welcome to do it, but you have to sing songs that fit your voice and that are helpful to singing. This song isn’t. Most girl group songs aren’t, especially not down the octave.

      1. If you haven’t taken lessons, developing support on your own is not easy and not that common. So don’t be disappointed cause I don’t hear much of support going on.
      2. Resonance is not an easy thing to have in singing, it takes the throat being relaxed, the larynx free, the soft palate being lifted, proper support engaged and good placement so don’t expect too much so soon.
      3. Not at this point. Unfortunately I hear a lot of air, little to no diaphragmatic breathing and some issues with pitch.
      4. You sound very much like a young baritone to me.
      5. What do you currently do to practice your singing? I’m more interested in knowing that to assist you.


  2. Hi Is it accurate that Eunji and Taeyeon have the best mixed register in the proficient category? Is the least developed one Wendy because she has no resonance or is it Jimin because she doesn’t have D5?

    Liked by 1 person

    1. In terms of overall openness and ease and development, I’d say so yes. I’d say Jimin because of her lack of development in upper support.


  3. Hey Ahmin,

    I was doing some vocal exercise the other day, however my throat went dry…
    Is it normal? or am I doing it airy and breathy?

    Thx 😀


    1. I can’t tell if I don’t hear you, but you have to make sure when you sing that you keep hydrating yourself and that could be the only issue.


    1. No? It’s one supported Eb5. The supported range includes a vocalist’s full CONSISTENT supported range. One Eb5 is hardly an indication of improvement or consistency, unfortunately.


  4. Hey Ahmin,
    I’ve been I have come back 🙂
    I’ve recorded other song : Open Arms 😀
    Last time I sent NoNoNo- Apink I put the link down to compare…

    Wish you answer all these questions:
    1- Any support? Where do i lose it?
    2- Any resonance?
    3- Good placement?
    4- How can I improve?
    5- Any improvement from last time

    Open Arms- Mariah Carey:

    I think that the first few note are not supported, But how about the rest?
    NoNoNo- Apink : (from last time)

    I literally filled Eunji comment section LOL
    I love you guys!!

    Waiting for your reply so bad,

    1. Hi George dear,

      I would like to ask of you that you do not post your audios on Eunji’s analysis as it doesn’t quite fit. I’ going to repeat what I asked last time. How do you currently practice your singing? I was unable to give you any meaningful advice because you didn’t respond to this question. I’d rather not hear you guess how to sing better by sending me audios of you singing songs you like. I appreciate that you like these songs, but I’d rather you practice in a way that’s meaningful. In a way where you’re focusing on your current issues, which include the shape of your vowels and throat, lack of soft palate lifting, pitch issues, tongue tension, nasality due to improper placement and mostly it’s cause you have an accent in English as well while not enunciating clearly and not keeping your vocal cords connected. How could you have improved from last time if I didn’t really tell you how? Do you do any vocal exercises? How exactly have you been practicing? Have you taken lessons?

      I do apologize for this late response.


  5. How about this performance?

    And this two. I think her ranking should not be there but I don’t actually know vocal. Just give more performance.


    1. I put your comments together. What is wrong with her ranking? There’s no ranking, we eliminated rankings. Even then we put a lot of performances in the analysis and these that you posted have been considered and already posted by other people in older comments and they show exactly the same kind of vocal patterns and vocal habits described in the analysis so I’m not sure exactly what you’re asking.

  6. Hey Ahmin,
    It is George from the previous comment 🙂

    The kind of practice I recently began doing is the half octave thing (C-D-E-F-G//D-E-F#-G-A…)
    However, when you mentioned that I have all those things: Tongue Tension (I watched your video on it several time, I thought I eliminated it…), not lifting the soft palate (I also though I got rid of it), shaping vowels, etc…
    How about breathing from the diaphragm? is it any good?
    I haven’t taken any lessons (only in internet), due to financial reasons…
    I am a violinist and a composer however, so I am not beginning from zero in terms of musical thing…
    Ah.. and for posting in Eunji’s analysis. I have posted a LOT here, only two are mine, plus being home as a fan of Apink LOL

    So, how can I improve? (like seriously, I never thought I have tongue tension! although I doubted having good breathing and nasality)…

    Sorry for the English both in the song and this comment hahahah

    You are amazing guys, just the way you support the people without even seeing them, keep it up 🙂

    With love,
    George A.


    1. I ask that you please not post your comments on Eunji’s analysis because they’re kind of irrelevant to her specifically. Well the thing is if you have an accent, it is very likely you’ll have issues with diction and tensions that are being brought from the other accent. Actually even native speakers of a language have to learn to sing a different way from how they speak in order to better vocalize without as many obstacles in the way. So English native speakers have to learn to enunciate their R’s less (R’s cause tongue tension oftentimes) or to sing with less tight spoken-like vowels and learn a more open version of them.

      I’d rather you focus on a simple two note exercise from vocal tips #8, and then work on other more specific stuff after better air management and vocal cord stretch are established. So instead of doing a 5 note scale, do two notes because it focuses more on vocal development, it targets issues a lot more closely and it is better in terms of focusing on breathing. Too many notes won’t help you much if you’re just starting.

      Thank you so much, you’re very kind and I’m very thankful.


    1. My guess would be no. Somebody actually asked this question about Bomi and Namjoo and I remember Ahmin replying months ago that neither of them has developed proper support


  7. In this performance, what was Eunji’s highest note? The highest sounds like at 3:27, but I’m not sure what it is. She also sang it briefly in 2012.


    1. That is a good point. What I meant at the point at writing this is that when she switches into her head voice it isn’t necessarily strained and she doesn’t have an unnecessary of pressure when she sings there.


    1. You mean why is her supported range not put as G3, as opposed to how it is right now as G3/G#3? Because at the time the analysis was written, we came to that conclusion. This video unfortunately doesn’t prove consistency. It proves that on that specific day she was very consistent with her condition on G3’s, but can she do it everyday every single time? We put the slashes because we also consider conditions of the vocalists when writing analyses. This is also not my analysis. I use non-slashes more often than Pandayeu whose reasoning is based on avoiding inaccuracies due to one’s condition and one’s lack of consistency due to muscle development. It wouldn’t change much within the context of the analysis for her to have G3 instead of G3/G#3.


  8. I think you forgot to change what’s written between the ()…
    It is now almost four octaves .. one semitone to become an octave… Lol please correct that too


  9. I just have a quick question about Eunji, it says in the analysis that she lightens up her mix around C#5/D5, which is where a mezzo would more likely begin to lighten up. However, you still believe that she is undoubtedly a soprano. Is that because her natural passaggio (like where she would have to begin mixing in general) is still that of a typical soprano? And do you know if her lightening her mix earlier is a choice or is it something she has to do? Like maybe because she has a heavier voice?


    1. At the end of the “Overall Analysis”, there’s a link on the word “Emotions”. It has a timestamp as well, so you will be directed to the part of the video that matters.


  10. 1- Eunji has Bb2, please update her vocal range,
    2- Eunji is connecting and supporting head voice up to Ab5 consistenly (check her Home perfornaces for there Ab5s in HV).
    3- Eunji has become consisitent to Eb5 in mix (you can find A LOT of Eb5s supported like the ones in the Home performances in the climax)


    1. Can’t wait to see opinions of admins from this page about the above video. Eunji has explored her head voice with pretty good placement recently.


    2. LOL most of her Eb5 is tense but with good placement tbh. Her head-dominant mix voice minimized the tension, it is like some people said Bada support Eb5, E5 but nope. Her Eb5 in Sugarman performance and the last note of Into the unknown is still strained.
      About her “headvoice”, most of them is pretty undeveloped, she push pretty much air into it, and below she still often use falsetto actually. Some get shallow connect but it is not enough to call it as a supported headvoice. Comparted it with Taeyeon’s G#5 in Because you love me you can see. It is pretty same case of Baekhyun and Seohyun’s headvoice, it’s undeveloped with too much air


    1. not one of the admins but those 2 E5s are her best attempts and i’ve been following her since 2014 , it been a while since her Eb5s did start to get better too


  11. Hello!! I have a question. I remember reading changmin’s analysis, where you wrote that he uses a “smile technique” which actually causes throat strain. I noticed a lot of singers tend to smile also when they sing, or at least show teeth.
    Eunji, I noticed especially has a smiley face too, but she sounds good and doesn’t strain. Is there something going on in the back of the throat that changes things so that even though all these singers are kind of “smiling,” they are not all straining? I learned that vowels are supposed to be narrow, so I don’t get how Eunji (or others) can smile while still remaining narrow. I’m very curious haha thank you for answering questions Ahmin! 🙂


  12. Hallo there! I am not Ahmin, but I will try to help you with your question. First of all, Changmin is a singer with quite a lot problems in the process of vocalization and a relative underdeveloped voice. So things like his “smile technique” tends to cause him more problems than with singers with stronger sense of support. This “technique” even though it helps the sound to be bright, it is also engaged the larynx and causes a lot of throat tension. In Eunji’s case, she tends to lack openness and freedom inside her supported range. She doesn’t strain but her resonance becomes smaller in size and not so well amplified. Now be careful don’t confuse this ‘smile technique’ with the inside smile that is used in classical singing, which helps the soft palate to rise, maximize the pharyngeal space (along with a proper low larynx position), while opening the throat and placing the sound forward.
