Girls’ Generation’s Vocal Analysis: Taeyeon [Newly Updated]

Vocal Range

D3 ~ C6 (2 octaves and 5 notes)

Supported Range

G3/G#3 ~ C#5/D5 (without head voice)

G3/G#3 – C#5/D5 ~ F5/F#5 (with head voice)

Voice Type



  • Consistent forward placement in the A4~D5 range
  • Consistent resonance in the A4~C5/C#5 range
  • Consistently supported up to C#5/D5
  • Occasional resonance up to D5
  • Forward masked placed sound in the chest voice
  • Supports and projects down to G3/G#3
  • Has done supported Eb5s
  • At times head voice can be produced up to B5 and resonance up to F#5
  • Capable of doing runs with good flow and pitch accuracy
  • Healthy vibrato is produced with good support
  • Stable pitch majority of the time

Points for Improvement

  • Pitch can be inconsistent
  • Faster runs can be sloppy and inaccurate
  • Support above C#5/D5 is inconsistent
  • Lower register below G3 becomes really airy
  • Inconsistent with vowels


  • Lower register: Since her debut, Taeyeon’s lower register has improved significantly expanding from Bb3/B3 to G3/G#3 since 2007. Her lower register has far more connection and projection than it did before.  Taeyeon carries decent support down to G3/G#3, however her voice has the most projection in the G#3/A3 range. Below G3 Taeyeon’s voice becomes very airy and unsupported, but she maintains a neutral larynx.
  • Mixed register: Taeyeon has consistent support up to C#5/D5 and consistent resonance up to C5/C#5. She generally produces very open and resonant notes in the A4~C5/C#5 range and occasionally up to D5. Above D5 Taeyeon’s voice becomes tight and strained.
  • Upper register:  Although Taeyeon actively switches back and forth between falsetto and head voice it is safe to assume she uses head voice. Taeyeon, when not using falsetto, can carry a supported head voice up to F5/F#5 though not resonant. Above F#5 her head voice and falsetto become very tense and shrill.


As a vocalist that trained under The One, who incorporates many runs into his performances, Taeyeon herself has developed a fair share of agility. Though overlooked in previous years, in 2015 Taeyeon made point to demonstrate her skill when it comes to agility. The most noticeable piece is “Check” from Girls’ Generation’s Party single which is filled with numeous runs from Taeyeon, similarly “Bump It” from the Lion Heart album also features many runs from TaeYeon as do many of the songs from that album. However in 2012 Taeyeon showed she was definitely capable of doing complicated runs live with her various performances of “Lady Marmalade” with Tiffany.  Taeyeon has shown she is best suited for slow to mid-tempo runs with faster runs she tends to lose control and rhythmic flow and her pitch tends to go off.

Overall analysis

TaeYeon made her debut in 2007 as the main vocalist and leader of South Korea’s leading girl group Girls’ Generation. Since her debut Taeyeon has made a name for herself as one of South Korea’s top idol vocalist and one of their most respected singers because of her many OST with her 2008 OST “If” being her most popular and the one that put her in South Korea’s eyes as a vocalist. TaeYeon is often praised for her ability to convey emotions as a singer. Composer Yoo Youngseok expressed his feeling about TaeYeon’s voice saying “Taeyeon feels like a woman who has been divorced 7 times”, meaning she is able to sing about heart break and parting well. Label mate JongHyun of SHINee expresed his agreement with composer Yoo Youngseok’s comment about Taeyeon saying, “I also feel that [Taeyeon’s] voice sounds like a woman with lots of experience of love and parting.” He reveals that he has felt this way about her ever since they were both trainees and Taeyeon “was born with the talent of expressing her sensitivity” showing his appreciation for his  label mate’s skill.

During her rookie years, TaeYeon used more chest resonance in her chest voice; therefore causing her to have a richer and fuller tone production. However later on, she switches to a lighter, brighter and slightly airier approach.  For example in her 2008 performance of “Reflection,” TaeYeon utilizes a significant amount of chest resonance in her chest voice and mix resulting in a richer and more womanly sounding tone, as opposed to her performance of “I Love You” in 2013 where tone quality was lighter and brighter in her chest voice and mix. This change is even noticeable when comparing mixed voice notes from then with more recent ones. For example in the way she approaches the C5 in “Dear Mom.” The C5 from this 2009 “Dear Mom” performance has more chest resonance and slightly fuller tone quality, whereas the C5 from this 2011 “Dear Mom” performance has a brighter tone production, but better resonance. Her switch to a lighter approach is neither negative or positive as it does not positively or negatively affect her voice.

In her mixed register Taeyeon uses a lighter and brighter approach , especially when compared to the beginning of her career. At the beginning of her career, Taeyeon had considerable development up to C5/C#5 accompanied by a strong, forward, and resonant sound within that range. For example the C#5s in “Baby Baby” had consistent support and occasional resonance, especially the C#5 from this “Baby Baby” performance having full, forward and resonant quality. She has also produced many good notes from this era in the Bb4-C5 range as well, for example in “Want and Resent” resonating C5s. Also during this time TaeYeon supported a D5 during her radio performance of “Counting Kisses with You.”  Although this D5 in particular was not resonant, it had connected support and power. However, this was a very rare occurrence. Taeyeon’s mixed voice above C#5 was very underdeveloped at this time which resulted in many of her D5s from “Into The New World” being strained.

Fast forward to 2010 not much happened for Taeyeon technically, except for her having her first studio F5 in “Wake Up” from the Hoot mini album in 2010. In 2012 SM Entertainment introduced the Girls’ Generation sub-unit TTS featuring members Taeyeon, Tiffany, and Seohyun. The unit’s primary purpose was to showcase the vocal talents of those three members. “Twinkle”, the leading track, required Taeyeon to sing F#5s in every performance. The F#5s in “Twinkle” proved to be incredibly difficult for her; not only were they were the strained, but also many of them fell flat because she did not have vocal stamina for them. Not only was she required to sing the F#5s in “Twinkle”, but also “Baby Steps” which was also part of the Twinkle mini album. Those F#5s mirrored the quality of the F#5s of “Twinkle”:strained, pushed and flat. After consistently straining her voice during that promotion period, Taeyeon began to have difficulty singing above C#5. In 2013 Girl’s Generation released ”Dancing Queen” and “I Got A Boy” both less taxing vocally than “Twinkle” and “Baby Steps”, however she was still unable to handle the D5s because of effects of the previous promotion.Although the “Dancing Queen” D5s were all quite strained and pushed 2013 was still a good year for her vocally. In 2013 Taeyeon produced some of her best C5s/C#5s and even had some success above above C#5. For instance Taeyeon’s C5s in “Lost in Love” had a very clean resonance and even vibrato; she even managed to bring resonance and support up to Eb5 while performing “Express 999” several times.

Taeyeon has made significant improvement in her mixed register by expanding her support range from C5/C#5 to C#5/D5. The D5 improvement was first noticed in the Lion Heart album released in August of 2015 in songs like “Green Light” and “Bump It.” The sustained D5 in “Green Light” had strong support and an open sound which was very different from her D5s in previous years, and the phrased D5s in “Bump It” also had good support. Taeyeon solidified her improvment with her performances of her song”I” from her solo EP I. Moving forward, Taeyeon D5s have become fairly consistent with support, for example her D5s in “Fine”  from her My Voice album were supported with good placement having a strong and full tone quality. However, she has a tendency to push her D5s because of them being at the top of her supported range, for example her D5s from performance of “Fine” on Sketchbook. However Taeyeon has shown she is completely capable of producing resonance on D5, for example her D5 in “U R” from her Butterfly Kiss concert and her D5 in “Feel So Fine” from Persona; despite the quality of the fancams, both notes have a very supported, projected, and clear sound.

Similarly to what happened in her mixed register, Taeyeon’s lower register has improved significantly over the years, expanding from A3/Bb3 to G3/G#3. Taeyeon for a long time had issues singing below A3 as her lower register was quite underdeveloped. This was especially evident below G3/G#3. Below that her voice would become very airy, quiet, and lack projection, for example her performance of her OST “Missing You Like Crazy” in which she sings many F3s which were consistently airy and not completely pitch centered. G3’s also posed a problem for her, for example the G3 in “Promise“, though there was significantly more connection on the G3 than the F3 that followed, it still sounded uncomfortable for her to hit. In recent years, Taeyeon has become more solid and consistent supporting G3/G#3 for example her G3s in “I Got Love” had a very full tone quality and projected well as well as sounding very comfortable and easy for her. This is because the muscle co-ordination in that area has strengthen and she is also committing to her chest voice better.

Taeyeon’s head register often flips between falsetto and head voice from what seems to be for stylistic purposes.  Her head voice has a fairly decent connection and support up to F5/F#5,but above that, in both falsetto and head voice, she becomes fairly tense and shrill. In more recent years, TaeYeon has significantly improved in the G5-B5 range being able to vocalize more easily up there. For instance, her B5 in “Fine,” although strained, has significantly more openness and support than her Bb5 in “Gemini” from her mini album. In addition, she has also shown more openness and resonance towards the top of her supported range, such as her F#5s from “When I was Young” which had a very strong connection to the support system with a very pure and whole sound.


Taeyeon is not one for dramatics when it comes to her singing. She’s definitely a fan of keeping a performance sensible and well within her means vocally. She’s a vocalist that likes to carry a performance by conveying emotions through phrasing.  Taeyeon definitely is not a high flying belter, as she stays in more a medium high to low vocal range maxing normally out at F3/F#3 and Eb5/E5, which is fairly consistent with her OST’s and vocal range in Girls’ Generation albums. Although of course there are exceptions to this, as she is occasionally challenged outside that range. Taeyeon’s performance of “Moonlight” is a great representation of her stylistically choices, as range wise she stays somewhere within the G3/G#3 ~ D5 range which is very reasonable for her vocal skill. This performance showed off her resonance in the A4 ~ C#5 very well as it was concentrated within in that area. TaeYeon’s solo album is a good reflection of her as a vocalist as the songs are very different than what is on the Girls’ Generation albums. Her style seems to be more mid to slow tempo songs in a lower range. A good example of this would be “U R” with a range of E3 ~ F5 centering more around the A4 ~ D5 area, which definitely was intentional as that is where she does well.

  1. Hey, I think I have already asked about this but I can’t seem to find my comment nor an answer so I’ll just leave it here and wait for a reply…

    Is the E5(?) at 2:40-2:42 supported???


      1. Cuidado com a palavra breast porque em inglês ela significa seio. But yes, it is a note sung with mixed voice, a combination of chest and head voice.


  2. Hey I just found a video of Taeyeon hitting a really low note.. I’m pretty sure it’s Eb3->C#3, so if it is, it’s lower than her current lowest, D3.

    @ 1:49


  3. About time to update this page, especially since she just held her solo tour. She’s improved so much since this list was made.

    She used to sing like a K-pop trained artiste(very safe and seldom deviating from what was recorded), but now she’s a fully fledged singer capable of displaying her own thoughts and emotions through her singing voice.

    I dare say she doesn’t eat CDs any more as her live performances now surpass her recorded performances by a huge margin. I would pay thousands to hear her sing UR live and I am envious of those that did hear that live.

    She has worked so hard for her ‘s.. concert and as a music teacher I can definitely see the results of her hardwork. Her recent concert was very good. Everything was sang 100% live except for the one song where she was on a rope for a small section. Even for that song she was singing, but the backing track was just louder.

    I have many artistes that I like in the pop music industry, but only Taeyeon I dare say I’m a true fan of.


    1. We constantly update our analyses and keep up with these artists. Except for her having built up more stamina around Eb5 and has been getting more consistent around that range, terms like “eat CD’s”, displaying emotions and such wouldn’t be things that would really be appropriate in the context of our analyses. As much as I appreciate your comment and what you’re saying, you haven’t actually provided any substantial reasoning as to what in this analysis is not up to date and what actually needs to be changed. So we can’t really know what you think is not correct with the analysis if you don’t tell us.

    2. Bold of you to assume that we haven’t been keeping up with her solo concert. What’s interesting is that you are claiming that we “update” her analysis because “it’s about time,” when you didn’t give us a reason to even prompt us to update it. You mentioned absolutely nothing about her technical improvements. You talked about subjective aspects of singing such as emotions and how you want to hear her sing UR live. Also how does her working hard for the ‘s concert and singing live(which she should be doing anyway) warrant an update?
      I appreciate your comment, but from what I have watched from her concert there really is no reason for me to update it. Thank you.

  4. Hi! So, I have a question that I’m not even entirely sure is something you guys would answer, because I’m not that sure that it has to do with what you do on this blog. But I’ll ask just in case.
    I found this tweet that says that Taeyeon did the vocal directing for Circus, and that it was her first time doing it.

    Circus is this song, by the way, in case you guys haven’t heard it.

    I was really just wondering what vocal directing is exactly.


    1. Can I ask how well she sang this note, considering the development of her chest voice? I know it was too low for her to support, but it didn’t sound (at least to me) like she was lowering her larynx or doing anything “bad” and forcing it. How was her approach on that note?
      Thanks in advance 🙂


  5. Hi Ahmin, this is Taeyeon’s new song “Voice”. At 2:44, seems like she hits an F#3 on the word “heart”. Can you tell me how is that F#3? Any degree of support? Cuz its tone sounds very full to me. Thank you, looking forward to your answer 🙂


  6. Through the years, I noticed that Taeyeon’s voice has the tendency to be nasal. Could you explain what contributes to it? Is it the technique?


  7. But i could almost swear she sounds better in that blocked video instead of in this audio video. There’s no other video unfortunately, they’re all blocked.


    1. Yeah that sucks, I’d love to be able to hear it. Maybe that clip is somewhere in twitter? Who knows, youtube really sucks sometimes.


  8. I’m not sure, but i think Taeyeon mix become more chesty than before, does she push more than usual? I don’t know but she doesn’t sing comfortably nowadays for me, maybe because of her health condition – depression issue, she has to take medicine when this show was recorded.

    And her falsetto is really bad though, her upper register is still airy and tense most of time…


  9. hello, yesterday taeyeon dropped her second full-album – purpose and there are a few gems there. but i want to ask about this song where she is mostly showcasing her low register. does she hit any new low notes? any development on her technique??


  10. I’ve been cross-checking this web for some female kpop analysis and was actually quite surprised that two of the top female Soloist in Kpop industry the other being IU actually has a. . err quite not much vocal range.

    I mean IU has never really tried a challenging song I know, she is comfortable in her own zone since she could write her own song, and brilliantly too, so people focused on the quality of her songs instead. But taeyeon tho. I am confused. I thought at least in SM entertainment Taeyeon is definitely the best. But not even in snsd. I am confused. I am thoroughly, genuinely confused. I am confused as to why SMent never let the other girls in snsd take the lead, instead of always giving the task of every high note to Taeyeon. (or maybe in other songs? not an snsd fans, only know their popular songs)

    I’m just glad that Mamamoo is as good as they’ve always sounded ❤ Those girls deserved more attention.

    Hi ahmin! I'm still obsessed with Speechless cover. And this site helped me a lot!


    1. taeyeon is literally a better vocalist than everyone in mamamoo. vocal range isn’t a testament to vocal skill, supported range is, and taeyeon’s supported range is quite good. also, the only thing stopping her overall range from being quite wide is her refusal to explore her head voice more, but seeing how easy c6s have become for her, it’s pretty likely she could go a lot higher. and c#3-g#5 is a pretty good chest/mix range for a soprano, so yeah lol.

      this is why rankings are important; people end up looking to pointless things like vocal range to try and rank vocalists if they don’t have a solid system to turn to.


    1. ‘U R’ from her Butterfly Kiss, when she support throughout the G#3 – D5, especially those resonance D5, one of the best – if not the best D5 of her career.


    2. nah i very remember the best performance was Lost in love with Tiffany, where she produce very much resonance but i feel UR should be too but i thought the was some inconsistent moments in that song


  11. Hi, I was watching some of her begin again performances and I noticed some parts she gets quite nasal. Is that intentional? Has she always been nasal sometimes? Because I’ve watched her for the longest time and it’s only now I’m starting to notice it. (2:35)

    I think it’s more apparent when she sings in English. Maybe it’s because of how she pronounces some things? (3:07 onwards)

    Maybe it’s because of the vowels (the ng)? Or is it not even nasal?

    This was not meant to be malicious. I just find it interesting how different she sounds now. Is she mixing lighter by the way?


  12. Is it possible if anyone could watch my cover of her song “Fine” and do a little vocal analysis on it? I would greatly appreciate the feedback!


  13. Can someone enlighten me about taeyeons current position? Is she still proficient or has she regressed/improved her technique? Can someone put her in an order (like…is she Haeri level? Eunji level? Or below?)


    1. taeyeon is still proficient. she showed a few good moments outside her supported range these recent years but not too major and consistent for her to be better than the time this analysis were written. she’s better than eunji but weaker than haeri


  14. Don’t know anywhere else to ask so I’ll ask here. Do you know Yuri’s (SNSD) supported range? because I heard some support in a few notes she has done before so I’m curious of she does have a support range or not.


  15. I’ve been hearing Taeyeon a lot lately and would you think that her support range is now consistent enough to be just D5 instead of C#5/D5?


      1. why choosing to compare her to solar who never used a real head voice ??? that quite odd , she was above average with C5/C#5 ; I don’t agree on the D5s in breath


      2. @Helena it was simply meant that apart from head voice, their other registers were kind of similar, perhaps in terms of support and resonant. Maybe English is not him/her first language so the phrasing were kinda odd.


      3. ??? that is pretty similar thing i don’t know why that girl got a bit triggered. They can compare, why not?? she said like Solar is bad or something
        also you can not agree but Ahmin said phrased D5 in breath carried support a long before, not all of it.There also some oldschool D5


    1. also given Solar is already one of strongest vocalist in AA category (duo to her consistent of her resonance), Taeyeon had like A3 -C5/C#5-F#5 (also had a nice G# but questionable consistency), better agility she maybe can sit a bit higher. tbh I don’t really like Raina (who sit between AA and Proficient) ‘s C#5, Taeyeon and Solar still had better mix


      1. girl i wasn’t triggered i was just surprised you compared her to solar cause their approaches are quite diffrent when it comes to belting/mixing, solar tend to shout with a bright placement, Taeyeon always had that edge in her technique development; she always had well chesty to well-balanced belts even above C#5 with some attempts. solar has that brightness as an advantage but she still a bit shouty, there’s also the fact that taeyeon always had a connection in her upper range which is not solar case , i know you made the comparison in terms of “supported range” . if we go deeper even in their preference of singing in general Taeyeon always had that affinity to try to sing lower than what she could handle in the past like she had more attempts in supporting G3s than E5s but it the opposite when it comes to solar , she always try to mix higher


      2. also a correction taeyeon didn’t support her head voice in her “before her glowup” years ; you think solar has better mix than Raina ? imo raina is more grounded and control better her mix


  16. Does Yuri of Girls Generation have shallow support ? In this video to me it sounds like most of her A4’s have some support in them, her clips are the first one.

    In the clip starting from 0:17 it sounds like she supported the E4’s and F4’s and maybe the A4, I’m also pretty sure the A4 at 1:34 was supported. I hear a different quality when she starts hitting the Bb4’s so I think she has support upto A4. I hope you’ll see this!


  17. Just letting you know Taeyeon hit a D6 in her new song @ 2:30, G5-A5-C6-D6 peak (it’s in the background and a little hard to hear but it’s there for sure)


  18. Hey Ahmin, how are you? I have a question. Who is better singer technically between red velvet Wendy and Taeyeon right now? I will be delighted if you can answer me.


  19. Just an update on Taeyeon’s vocal range in the video linked. Taeyeon’s actual vocal range is now B2 – G#5 – D6, which is 3 octave, 1 note and 1 seminote. It’s amazing that she can go down to the second octave.
