T♔ARA’s Vocal Analysis: Soyeon


Vocal Range

E3 ~ F5 (2 octaves and 1 semitone)

Supported Range

A3 ~ Bb4

Voice Type

Light Lyric Soprano


  • Strongest vocalist in T-Ara
  • Natural even vibrato is produced
  • Pitch is mostly quite accurate
  • Able to transition seemingly well into falsetto
  • Falsetto can be for the most part relaxed
  • Generally favors falsetto over straining in her mixed voice
  • Support is consistently present in her mid range
  • Can support her voice as low as A3 with consistency, rarely even G#3
  • Able to vocalize well up to Bb4 with support in her mixed voice


  • Often lowers her larynx below A3
  • Generally sings in a very narrow range, limiting vocal growth
  • Mostly places her voice in her nose
  • Above Bb4 generally shows glottal tension
  • Loses projection and power above C5, sings with a high larynx
  • Never been able to truly showcase a head voice
  • Underdeveloped mixed range
  • Shows tension on certain vowels, such as “Aye (애)”
  • Vocal runs are mostly messy and pitchy


  • Lower register: The lower range is the most explored and often used part of Soyeon’s range, even then it’s still generally under developed. Often pushes her larynx down below A3 to project in a range she can’t support in.
  • Mixed register: Very under explored as a range, she has enough ease to hit D5’s with her mix without too much trouble but does not often sing above that. Support is present in a balanced mix up to Bb4.
  • Upper register: Not ever able to showcase a connected head voice, mostly uses an airy disconnected falsetto, but within the showcased range she is mostly relaxed.


As a vocalist, Soyeon has yet to be given enough chances to truly showcase her ability as a vocalist, therefore due to the lack of material she’s been able to put out, she generally sticks to easy pop melodies and ballads, within a narrow range. When attempting things outside her comfort zone, such as more R&B melodies with ornamentations, such as runs, it is possible to hear issues with her ability to control her voice. She mostly has issues with not only not separation, but being able to sing runs with the correct rhythmic flow and smoothness, as well as note accuracy, generally resulting in sloppy pitchy runs, such as in “길에서” and “Stickwitu“.

Overall analysis

Debuting in 2009 as the main vocalist of T-Ara, Soyeon has had a very long and extensive career over the years as a member of T-Ara, but she’s yet to truly showcase her full vocal potential. Unlike many idol groups, T-Ara has pushed Eunjung and Hyomin forward as vocalists of the group for shows such as Immortal Song 2 or Yesterday, resulting in Soyeon never truly getting the recognition as the main vocalist of the group. With a voice that has clean support and cuts through with a more mature and full sound amongst the T-Ara members, Soyeon would most likely be classified as a light lyric soprano due to the lightness of her voice and the high placed range her voice naturally sits on.

The lower part of Soyeon’s range is one that’s adequately developed in both support and range and has been somewhat explored over the years. Unlike most sopranos in K-pop, Soyeon doesn’t always go for an airy approach in her lower range and instead falls victim of a different bad habit, often lowering her larynx in order to project in her lower range, ultimately causing vocal strain by creating a sound that’s not true to the tone of her voice. Soyeon has been able to show consistent support in her lower range down to A3, such as the Bb3’s in “여자는 배 남자는 항구“, and A3’s in “사랑밖에 난 몰라” and “사랑아 가지마“. Below A3, there have been times where she sings with an airy tone, such as the G#3’s in “느낌이 아니까“, G3’s in “뭐라고 끝낼까“, and E3’s in “Breakaway“, but most of the time an added fake darkness is present in her lower range with the lowering of her larynx, such as the G#3’s in “Love Poem“, G3’s in “Breakaway“, F#3’s in “눈의꽃” and F3’s in “모나리자“. There have been rare occasions in which she’s been able to carry support down to G#3, such as in “아파“, but such occasions unfortunately show inconsistency in her ability to properly support her voice and keep a stable larynx below A3.

Her mixed range is one that’s very balanced in the fourth octave, generally not overly pushed or full of chest development, Soyeon uses a nice balance of head and chest voice in her mixed voice. This support is generally present up to Bb4 with consistency, as heard in the A4’s in “좋은 사람” and the Bb4’s in “떠나지마“, “산라의 달밤” and “揮著翅膀的女孩“.  This support can show inconsistencies depending on the vowel used, such as the Aye (애) vowel Bb4 in “그대가 그대를“, and above Bb4 support becomes less present and tension generally takes over, as heard in the B4’s in “Falling U“, “Wanna Be“. Even though she’s able to support her voice up to Bb4 in her mixed voice, she shows issues with keeping a lifted soft palate and often places her voice in her nose, having yet to show the ability to produce proper resonance in her voice. Above C5, her mixed voice becomes more head-dominant and although strain is present, it becomes less damaging to the voice due to the lighter vocal approach she uses. Although a lighter vocal approach is used, strain is still heard above C5 due to the weaker breath support used in order to reach those notes, as well as the tight throat tension and high larynx present in her voice, such as the C5 in “사랑아 가지마“, C#5 in “30전에“, D5’s in “Sugarfree” and F5 in “뭐라고 끝낼까“.

Her upper register consists of using a falsetto register in order to sing above her mixed voice. She oftentimes transitions up into her falsetto instead of trying to mix higher above C5 and for that, she’s often able to transition quite well up into her falsetto, such as in “눈의꽃” and “Bye Bye Bye“. With that being said, her falsetto is mostly relaxed with an airy quality and is produced without true breath support, where the vocal cords are not fully touching and she’s unable to create a connection between all of her registers, shown in the E5 in “Bunny Style” and the C#5 in this “Acapella” cover. Thus her upper register has yet to be truly explored and developed into a head voice where she’d be able to control her voice better dynamically and produce true head resonance.

Musically, Soyeon has very little issues being able to properly change her voice dynamically in terms of volume in order to properly convey the message of a song. Compared to every other T-Ara member, Soyeon is the only vocalist in the group with an understanding of good breath support where she’s able to vocalize fully supported notes within an octave of her range, whereas every other vocalist in the group rely on poor and shallow breath support with airy vocal tones and weak tone production. Not only does she have the best support and tone production in the group, she also produces a very nice even and healthy vibrato within her supported range. Her weaknesses lie mostly in her placement, issues with keeping a stable larynx but most of all, the fact that she always stays in a very narrow range and does not truly explore the full potential of her voice, although that also keeps her from straining her voice and risking her vocal health like many idols do.

Vocally, Soyeon is very underrated as the main vocalist of T-Ara, not only is she not promoted outside of T-Ara in vocally focused TV shows, even within T-Ara shows, challenging vocal parts are usually given to weaker vocalists with brighter mixed voices who have more volume to their voices with more vocal strain, often overshadowing the fact that Soyeon is the member who’s most likely to be able to actually sing such challenging parts the best. For future improvement, working to truly come out of her comfort zone and explore the development of her mixed voice, breath support and perhaps being given more chances to challenge herself vocally could help her strive to improve as a vocalist.


As a safe and smart vocalist, Soyeon is yet to come out of her shell in many ways, one of those being her ability to not only improvise new melodies in her vocal performances, but really take a song and make it her own. Most of the time, one could see Soyeon as more of a vocalist who sticks to the original melody of a song and tries to stay true to it concentrating more on the lyrical delivery, than trying to add melodic changes in order to show off vocally, indicating that perhaps she may lack the confidence to take a song and twist it around as if it was her own.

    1. She’s very close to them in level. I’m not sure about Sunny but Tiffany has a better lower range. Sunny has a head voice, they might be above them.


  1. I like the crown you out on “T-ARA” :3

    “she has enough ease to hit D5’s with her mix without too much trouble but does not often sing above that. ” She has ease in mixing B4-D5s but it’s not supported?

    Too bad she doesn’t really mix high nowadays, it seems like she’s afraid she’ll crack if she does lol
    I never thought that she could mix a F5 until i watched the vocal range video lol


      1. He was singing in falsetto, E5’s, through his nose, there’s quite a bit of throat tension and he’s singing with a high larynx, he’s a tenor so him being able to hit E5 is not exactly surprising to me but I never thought he’d go for it in songs. His pitch is not bad. I think GD is a rapper and it’s not fair for me to analyze his singing when it’s not his main instrument/artistry.


    1. No not at all, she has support. She is average because she has very nice support, she is safely average. Minzy has resonance, that’s what helps her. Also of course you can produce a healthy vibrato while nasal, nasality has to do with placement not support.


    2. Oh. So that explains why I am able to produce a natural vibrato two nights ago while demonstrating to my friend how does it sound to have a nasal and overly-bright mixed voice. At first, I thought I was just imagining it until my friend asked me how to do a natural vibrato.

    1. Maybe Hyomin at one point, because she’d be the second strongest vocalist in terms of technique but I have no intentions of analyzing Jiyeon or Eunjung.


      1. I’m not sure but in my opinion Hyomin’s vocal is way more stronger than Soyeon, cuz she can belt the high note. However I dont know anything about the vocal analysis xD Hope to see your analysis for Hyomin as soon as possible xD


      2. I’m not sure that we will analyze Hyomin I’m afraid. I do believe Hyomin has better technique than Eunjung, but her sense of support is still not very good.


  2. Soyeon did a lot better than I thought she would! I always knew she was technically the strongest in T-Ara despite being the lovable yet lazy main vocal. Are you planning on doing the rest of T-Ara’s vocal line?


    1. Make sure to check the future analyses page when making requests. As for K.Will I’m waiting on a friend to finish a vocal range video for him first.


  3. Is there a reason why she doesn’t take on the high notes? it makes more sense for her to be the belter of the group if she is the strongest vocalist instead of having Eunjung doing the notes


    1. I have no idea because as the main vocalist, it would make more sense to give her the high notes than to let Eunjung strain her high notes all the time. Eunjung and Soyeon can sing about the same range, but for some reason they give the notes to Eunjung instead.


    1. I don’t know who’s who so I can’t tell you by name who’s better and these are weekend show performances where they’re dancing, so it’s not very focused on good vocals. What I can tell you is I do not hear resonance from any of these vocalists so nobody stood out to me yet but we could consider them of course! ^ ^


      1. Yeah, sorry. I didn’t have time to find any good videos of them singing because it’s hard to find many videos because they aren’t the most popular… and I also get distracted looking at them dance😄. I hope you can do them, but I’ve looked at the projects and you guys are really busy. I am really greatful for all the work you do! Thanks so much!


  4. no surprise she’s the strongest, but yeah, I think average fits her to a T. When I think of an average vocalist, for me Soyeon fits the word average to a T. Thanks for the analysis, I think the ones who I’ve been waiting for the most are Soyeon and Taeyeon, so now all that’s left is Taeyeon. I can’t wait for hers. Thanks for all the hard work again, guys.

    also, may I ask what rank you’d give Yoon Mi Rae? If you’re familiar with her.

    Liked by 1 person

    1. I am only partially familiar with Tasha, she seems like an average vocalist, she’s really a rapper with a pretty singing voice so I wouldn’t think it’s fair to judge her singing.


      1. Fair enough.

        Also, which kpop girl group would you considered weakest and strongest in terms of vocals? I know lots of groups have weak members, and then strong members (F(x) has Luna but the rest are pretty weak, etc), but in terms of who has the most overall well-rounded vocals, who would you choose? I think it’s SNSD. Also, excluding groups like Mamamoo and Red Velvet who just debuted a year ago. Are T-Ara, Kara, or 2NE1 the weakest?


      2. Id say Kara, Dalshabet and 9muses are pretty weak. CSJH The Grace, 15&, Davichi are pretty strong vocal units. If not then TTS, Spica and BEG.


  5. Are y’all going to make a vocal ratings list saying whose better in terms of skill than who?

    Plus I’ve been meaning to ask tips on how to extend my mixed range because its very limited.
    I think I have a bass type cause my lower range is d2-f3. I’ve been trying to improve my middle register/
    My middle range is about b3-E4. And e4 is quite strained. Are there any tips to a healthier middle range. Because anything after is falsetto from about c5-c6



    1. Yes after we’re done with a good 90% of the analyses of the vocalists who will be included in the vocal chart, it will be released. Have you seen my vocal tips videos? They should be able to easily answer your question. I think you might be a baritone, it’s very rare for a boy to be a bass, don’t base it off of vocal range. I’d need to hear you sing but do watch the vocal tips videos.


    2. Just a question: I have a friend who starts mixing at A3 and has tone even at B1. He said that his vocal coach classified him as Bass. Considering he is trained with classical technique, do you think he is correct?


      1. If his instructor has called him a bass, I don’t see why not although A3? That could very well be a bass-baritone passaggio.


  6. Sorry to bother but may I know what u think about former T-ara member Ahreum in this song? (She only sang 1 part though…) I just wanted to know if she knows how to support. Or she might be better than Eunjung/Hyomin? It’s okay if it’s too short to be know. Also about the other 2, Shannon and Gunji, I guess Shannon did the best here right?🙂


    1. You might want to tell me who Ahreum is, but if she’s the girl on the left then yeah she does know how to support. She reminds me of Gunji’s style.


    2. Ahreum é melhor que Soyeon? Ahreum consegue alcançar high notes, enquanto Soyeon não, Ahreum foi melhor que Soyeon em Day by Day?


      1. Quem disse essa barbaridade? lol Cantar mais agudo que uma outra pessoa não quer dizer nada de especial, com essa lógica a Eunjung seria melhor que a Soyeon por cantar mais agudo que ela mais frequentemente que ela. A Eunjung não tem suporte e a Ahreum tava fazendo Rap a maior parte da música, ela não consegue abrir a garganta quando chega perto de B4, então não vejo como ela seria melhor que a Soyeon. A Soyeon nem canta em Day By Day lol A Soyeon consegue cantar F5, eu acho que ela tá de boa na hora de gritar umas notinhas agudas para provar que é soprano pelo menos, que nem a Eunjung que grita até A4/Bb4.


  7. How would you rank these average vocalists: Soyeon, IU, ChoA & Minah?
    If Soyeon can support her B4 consistently, will she be an A to AA vocalist?
    Thanks in advance.


  8. did you check all her live in shows? like Hidden Singer and Song for You?

    I’m not a expert, I’m just asking. I think she could be a good to average singer if mbk explored her voice a little more, and they make her look like a lazy singer.


    1. Yeah don’t you see all the links in the analysis? They’re all in there. I think it’s all about training, she just needs to be better looked after.


      1. sorry I let it playing and probably missed lol

        she did even said in a interview that she would probably never show all her potential, because is not what the company wants and demand from t-ara… which is really sad because she could get in a lot of music varieties with her unique voice.


  9. Hello, I have some questions about Soyeon singing.

    Did she support her voice @3:07-3:14 (I mean the A4 and the two B4s)

    Also, do you think that she has shown any improvements or regression, even subtle changes, since her debut?

    What can she improve to be considered a to aa or just aa? I’ve read your advice for her in the analysis, but I want to know more specifically. (Like what the most necessary improvement is, etc)

    Thank you very much ^^


    1. I thought it was G#4, A4 and then B4 …the B4 had very little tension. I don’t think she regressed, I just don’t think she ever tried to take risks with her voice which is both good and bad. Working on better openness and support, consistent resonance is part of being an AA vocalist. Producing it at all would help her rise up and improve. C5 is kind of a must for a Soprano as well, supporting it that is and with resonance.


      1. You mean her B4 kinda supported, don’t you?
        If she stop projecting through her nose, she would be able to achieve resonany, wouldn’t she?
        I think she’s really tried to improve her stamina recently so she can sing quite well while dancing. In the past she used to lipsync most of the time due to bad stamina, so people consider her as a worse vocalist than Jiyeon and Boram lol.


      2. It doesn’t work that way automatically. There are vocalists who don’t produce resonance but are also not nasal, like Wendy. Resonance has to do with both placement and openness in the vocal track. The B4 had some support yes, it wasn’t 100% there.


  10. Was her voice cracked at 2:45? Or she just went a bit sharp? It sound kinda funny lol
    Also how was her high note? I know it’s not good but she hasn’t hit note above C5 for while so I’m really curious.
    Thank you ^^


      1. One of these videos, the Butterfly chinese song one was actually mentioned and linked in the analysis, specifically that note I believe which is a Bb4, well within her supported range. The other note is a somewhat pushed B4, not a very high note but not badly executed.


  11. The first time I heard her sing, I was completely blown away by that nice, deep and emotional voice. I do agree that Soyeon is a smart and safe vocalist who never goes out of her comfort zone, though I am surprise that she is actually a light-lyric soprano. I always thought she was a mezzo, so thanks for showing me that.

    I know it is a lot to ask but since your analyses are very comprehensive and your knowledge is really admirable, I want to hear your opinions on these three Japanese artists: Mika Nakashima (Soyeon often covered her songs back when T-ara promoted in Japan), Flower’s Reina Washio, and Kana Nishino. I have no idea who to go to, so I would greatly appreciate if you could tell me about their voice type and whether they are good singers or not. Again, thank you very much🙂

    Mika: https://www.youtube.com/watch?v=AY-xk03XtdI

    Reina (the girl with short hair who sings the introduction, the pre-chorus and the chorus): https://www.youtube.com/watch?v=eH1qA0LwI7I

    Kana: http://fansoop.com/2015/03/pv-kana-nishino-aitakute-aitakute-subbed/


    1. We really don’t analyze non-Kpop vocalists but since it’s your first time, I’ll be brief. First let me thank you for reading the analysis and for the compliments. ^ ^ I can’t watch the video for Reina because it’s not available where I live. I’m listening to Mika and Kana. Kana is definitely a Soprano. Neither of them have good breath support or placement. They both place their voices in their noses a lot and sing straight out of their throats, it’s a very common trend amongst Japanese vocalists. Mika might also just be a Soprano too actually, but she pushes her larynx down when she sings so she sounds somewhat lower than her natural voice tone. She has a thicker and tighter approach to her singing, whereas Kana sings with a brighter approach and a high larynx.


      1. Nah, you deserve all the compliments for not only your understanding but also your attitude when facing questions that are not related to K-pop like mine.

        Regarding your analyses, I mean that’s really all I ask for – a brief overview of their voice. Singing straight out of the throat is a damaging technique, right? Now I know why there was a period when Mika went on a hiatus for vocal recovery.

        As for Reina’s song, here is another link https://drive.google.com/file/d/0B98Mlu5rJjIGZWJMbWxhRi1YOWM/view?pref=2&pli=1 (Reina has a short bob haircut with blunt bangs). Among the three, she is the person I look forward to hearing your analysis the most. She has that angelic voice that moves my heart everytime I listen to it. So please help me with her and that would be it. Thanks heaps ^^


      2. Again, thank you so much. ^ ^ Yes singing from the throat is damaging, it means no support is being used in one’s singing. The one singing at 1:24? This is a really pretty video. Mhmm she is a bit different from the other ones, although I hear shallowness in the higher parts, that are barely high, I hear actual support. I’d guess she’s a soprano too, most likely. She seems to be most supported one from the three you asked about. It’s odd to me but I’ve never heard a Japanese vocalist who favors powerful or technically skillful singing, so Idk a single male or female japanese vocalist who truly could be considered even Above Average, at least not off of the top of my head.


      3. Yup that’s her – the girl who sings majority of the song. Among the current J-pop idols, I personally find her being the best in terms of technique and emotions. Depending on the nature of the song, Reina can adjust her voice to evoke all kind of feelings such as regret, nostalgia, happiness and outrage. And although I do not know much about vocal technique, I have always felt a certainty (or support as you would like to call) in the way she belts out notes.

        Well, Japan is the world’s second-largest music industry so I guess they have their own way of doing things. Probably they choose not to follow what have been practiced by singers out there and re-invent how one should handle a song. Or it has to do with their voice and their language. I remember reading elsewhere about Japanese people having a limited vocal range so maybe, just maybe, it affects their abilities to grow technically.

        That’s why I come to love these 3 vocalists. Technique aside, they stand out due to the emotions they infuse into a song and how they do not sound weak or whiny like other J-pop acts.

        Again, it is really nice talking with you🙂


      4. Well emotions, that’s not something we can objectively argue about so we don’t talk about that. However, I’d still call her technique still quite week. Kokia and Ito Yuna are two of the stronger Japanese vocalists I’ve ever heard, but that’s it and they’re not that strong. I don’t think it’s much to do with the spoken language cause spoken Japanese isn’t nearly as glottal, low larynxed or nasal as sung Japanese. No problem, thank you for coming by. ^ ^


    1. Hi Sphello, I’m not a vocal coach but It’s important to know that classical singing and pop singing cannot be analyzed based on the same criteria. This “Ave Maria (by Caccini or Vavilov)” you just posted is a classical-style song. Female classical singing mostly uses head voice, while female pop singing is done mostly in chest voice and mixed voice, with only occasional use of head voice and falsetto. In pop singing, vocal resonance must be placed forward, while in classical singing, that’s not the case. They are two completely different singing techniques. It is good that Kokia does both classical singing and pop singing, but when she sings a classical-style song like this, her techniques must be analyzed based on the criteria of classical singing. Instead, you need to go listen to Sumi Jo’s Ave Maria or Katherine Jenkins’ Ave Maria, and see how they sound😀

      Now, let’s talk about pop singing. One of the major weaknesses of Japanese pop singers’ is their mixed voice. Listen to Kokia’s mixed voice, or Kana Nishino’s (mentioned in the post right above) mixed voice. What many young Japanese female singers do to connect their vocal registers is to weaken the amount of compression of their vocal folds when their chest voice ascends and approaches their first passaggio. In this way, Kana Nishino connects her chest voice to her falsetto all the way up to G5 or A5. However, if you connect your voice in this way, you would never achieve power and volume in the belting range of singing; you wouldn’t be able to belt in chest-dominant mix. Someone posted Nana Mizuki’s live performances in the SoHyang’s vocal analysis page a few months ago, and the same can be said of Mizuki’s mixed voice as well. As an exception to young Japanese female singers, Shiho of Superfly does belt in chest-dominant mix, but unfortunately her chest-dominant mix only reaches up to E5 or so, and at around F5, her voice strains. They need to do something about their mix🙂

  12. i really want you to do en jung and hyomin. sometimes i feel these 2 cannot singging well but other time the pretty good. make me confused, they can sing or not although i think they not the very good vocalist


  13. how would you rank IU,taeyeon,ailee,eunji,hyolyn,luna,U.Ji,park jimin,raina,kim boa,soyeon,eunjung,tiffany,minah and solji in vocal ablities/skills/technique????


    1. We literally analyzed every single one of these vocalists except Eunjung so the answer is in the blog if you take the time to read their analyses. Eunjung is the weakest of them all, she’s a weak vocalist.


      1. so it goes sth like this: ailee>U.Ji>luna>taeyeon=eunji>park jimin>raina>hyolyn>solji>kim boa>minah>IU>soyeon>tiffany>eunjung??????/ because that’s what i understood..if you have any corrections to make,PLEASE DO ’cause i am no expert


      2. That’s close! Not quite there though. Ailee >> Luna > U.Ji > Park Jimin > Taeyeon > Eunji > Raina >> Hyorin > Solji >>> Tiffany > Kim Boa > Minah > Soyeon >>>>>> Eunjung would be more accurate. For the full ranking just wait for the chart we have planned to be released eventually.


      1. Well yes I know you mean her technique but I am asking you like in what way? You shouldn’t rely solely on what other fans tell you because a lot of what they say tends to come from personal taste. You mean her head voice? Yeah she can use a head voice but it has absolutely no support at all.
