WINNER’s Vocal Analysis: Seungyoon


Vocal Range

F#2 ~ C6 (3 octaves and 3 notes)

Supported Range

Bb2 ~ Eb4

Bb2 ~ Bb4 (with head voice)

Voice Type

Lyric Baritone


  • Strongest vocalist in WINNER
  • Support is consistent throughout his mid range
  • Mixed voice remains supported up to Eb4
  • Some support can be carried up to E4, very inconsistently
  • Able to use a connected supported head voice
  • Able to produce resonance
  • Lower range remains present even below where support is present


  • Tends to push his mix with his throat
  • Inconsistencies with support around E4 and above due to harsh approach
  • Favors style over technique which causes him to be aggressive in his singing
  • Tends to not open up his throat enough
  • Resonance is produced rarely
  • Nasality can be present in his singing
  • Usually uses falsetto with a lot of pushing and throat tension
  • Lower range below Bb2 is not used often, under-explored


  • Lower register: His lower range mostly remains underused but decently developed. He has enough vocal cord strength in his chest voice muscles to be able to maintain tone throughout his range, although support seems to not be present often below B2.
  • Mixed register: His mixed voice is mostly quite chest-dominant. He tends to push his chest voice into his mix as he ascends in range and is able to maintain support up to Eb4. Above that he tends to be too throaty and support becomes inconsistent.
  • Upper register: At times able to use a head voice, mostly within a reasonably lower range. Tends to push too much air pressure into his upper head voice and falsetto range, causing him to sound strained.


Stylistically Seungyoon tends to draw his influences from a more indie and rock genre direction, as opposed to R&B or other genres that tend to be more run-heavy. Thus, it can be noticed that he tends to avoid doing vocal runs most of the time, with the exceptions being occasional soul songs or slow runs in simple R&B songs. The few times he’s attempted vocal runs, he tends to show a lack of ability to maintain proper breath support and smoothly connect each note in a run. Instead, he tends to become pitchy and sloppy due to an improperly used muscle memory. His main vocal habit is to add a lot of pressure into his vocal cords, which causes them not to be relaxed enough for him to have enough flexibility in his voice, resulting in his voice being somewhat slow. Examples of this include his runs in “Ordinary People“, as well as “그리워해요.”

Overall analysis

Kang Seungyoon initially debuted as soloist after participating in the second season of Superstar K, in 2013. Shortly after, he re-debuted in 2014 as the lead vocalist of WINNER after participating in the survival TV show meant for YG’s next boygroup debut. His style is often very rock-oriented and he tends to show his skills as a vocalist, songwriter and instrumentalist by writing his own songs while accompanying himself playing his guitar. His voice is unique in the sense that while many other main and lead vocalists of idol groups tend to be high tenors, Seungyoon is one of the few baritones currently active as a main or lead vocalist in a male idol group. His voice is thick in tone and generally dark overall, enhanced by his rough approach in his singing.

His lower range can be quite well placed and connected, while maintaining a considerable amount of vocal tone. However most of the time, he tends to only maintain the right amount of breath support and connection of his vocal cords as low as Bb2, while losing the true consistent sense of breath support anywhere below that. His chest voice tends to be quite well placed in his chest with a strong development of his chest voice muscles down to Bb2, where he seems rather comfortable and consistent. Due to stylistic reasons, Seungyoon doesn’t often sing below B2, but the few times he’s done so it’s possible to hear a drop in sound, such as the G2 in “Lonely“, or a drop in support, such as the F#2’s in “Baby Goodnight.” Examples of him showing a good amount of breath support and connection in his lower range include the C#3’s in “Someone Like You“, the B2’s in “같이 걸을까” and the Bb2 in “반달친구.”

The most used and highlighted part of his voice is usually his mixed voice. Since WINNER’s music is written for 2 tenor vocalists and 1 baritone vocalist, it wouldn’t make much sense for their music to be too high or too low for either voice type. Generally sitting on a comfortable range from C3 ~ A4, none of their vocalists usually belt too high or sing too low. Due to this, Seungyoon is never truly able to explore his lower range much but tends to constantly sing at the top of his mixed voice. Most of the time, their songs are written in a mid-range for a tenor and slightly high range for a baritone, where Seungyoon is able to show support and maintain an adequate amount of technique.Up to D4 and Eb4, Seungyoon shows that he can maintain a relaxed approach and even produce resonance occasionally, as heard by the C#4 in “Someone Like You” and D4 in “Baby Baby.” Up to Eb4, Seungyoon is able to maintain enough breath support to outdo his bad habits and still keeps a relaxed enough approach in his throat, as heard by the Eb4’s in “당신께 쓰는 편지” and “시간을 거슬러.”

Above Eb4 he tends to use his throat more and although support may be present on his E4’s, it’s usually overshadowed by him not being completely relaxed and pushing too hard with his throat muscles, as heard by the E4’s in “Someone Like You“, “Lonely“, “그리워해요“, “우리 헤어졌어요” and “Ugly.” Above E4, Seungyoon has never shown the ability to maintain breath support at all and tends to use his throat almost completely. This can be attributed to his stylistic choices by drawing influence from the rock-genre. As a result, instead of using proper breath support while keeping his rock-style approach, he tends to push his mixed voice out with a lot of chest-dominance and throat tension, as heard by the F4’s in “恋しくて (Begin)“, “말할 수 없는 비밀“, “비가 온다“, F#4’s in “This Time“, “Wild & Young“, G4’s in “궤변 광란의 축제“, “0 + 1“, “Baby Baby“, “공허해“, G#4’s in “Je T’aime“, “Someone Like You“, and A4’s in “시간을 거슬러.” This is not to say that he hasn’t shown improvement over the years. Compared to his Superstar K days, Seungyoon has made very good progress in his breathing technique and being able to sing with less pushing around the D4 ~ E4 range, if contrasted to performances like “본능적으로.”

His upper register usually is a very lightly approached and supported head voice, which is usually well transitioned into when singing with less volume. His transitions become less smooth and he may end up switching into a falsetto when he goes from his upper mixed voice with more chestiness up to his upper register. This is caused by him using too much of his thyroarytenoid muscles that when transitioning into a more cricothyroid-dominant cord function, he’s using too heavy of an approach and switching to a much lighter use of his vocal cords becomes too abrupt, thus making him use a thinner airy falsetto instead. However for the most part, he’s able to use his head voice and is able to support up to Bb4, as heard by the E4’s in “우리 헤어졌어요“, G4’s in “Lonely“, the G#4’s in “시간을 거슬러” and the Bb4’s in “Je T’aime.” Above that, he tends to either use falsetto or simply use an overly excessive amount of throat tension and air pressure, causing him to sound tight and strained, as heard by the B4’s in “0 + 1“, C5’s in “Baby Baby“, C#5’s in “Je T’aime“, “아름다운 나비” the Bb5’s in “Tonight.”

In terms of overall technique, Seungyoon has a few issues with overly using his chest voice when singing higher, which can cause him to sound compressed and at times may cause him to go flat in pitch. Most of the time however he possesses quite a good sense of pitch with a good understanding of dynamics in his singing. Although it may become limited when he sings above E4 in his mix, he tends to be able to control his voice well below that. His vibrato also seems to be a bit of a problem, with signs of laryngeal movement as opposed to relying solely on a natural vibrato. This causes his vibrato to become quite fast and forced out.

Overall his technique is actually quite adequate for a young vocalist like him. His sense of technique helps him in his songwriting and his overall understanding of music help him communicate his lyrical content very well with his voice. He is very self aware and sings in a specific genre, which works with his current level of technique. For the future however, he would be quite limited to one genre, while the amount of tension and forcefulness in his mix can be quite damaging to his vocal cords and cause him to have issues if he does not change his approach in singing. For the future, learning to relax and balance out his mix would be the most important step in order to improve his overall technique.


As a songwriter, Seungyoon tends to have a lot of freedom when performing covers of songs. As he’s able to accompany himself with a guitar when singing, he has more control of how to perform the songs he sings. Since he has more control, he’s free to alter the melodies of songs as he pleases and he tends to add his own melodic ideas to many of his acoustic covers. They may not always work effectively, but he tends to find success most of the time with subtle changes in most of his covers. Harmonically speaking, Seungyoon tends to sing with a lot of chest-dominance in mix, so when harmonizing he finds it easier to harmonize when singing in his upper mix, than when singing in his head voice since then he lacks the proper blend if he has to harmonize with his head voice while someone else is belting, as heard in his cover of “Ugly” with Big Bang’s Daesung. Otherwise, his harmonies tend to be quite clean if the vocalists are matching in dynamics, as heard in “Sunday Morning” and “그리워해요.”

  1. Congrats on your new domain! And thanks for analysing Winner even though they’re so new and probably don’t have tonnes of material.
    I don’t know why YG trains their vocalists to have no support and minimal resonance. I get it, you’re a hip hop focused company, but please.
    With Minzy now gone (and not taking Lee Hi or AKMU into account) Winner’s vocalists are the strongest in the company. That’s pretty rough but I hope they can improve at least in the future,
    Would you agree that YG’s vocalist have the weakest technique in the Big 3 or would that be JYP?


    1. Honestly what saves JYP is 15&, but their technique isn’t good because of YG’s training system. Aside from them, the best vocalists they have are three above average vocalists, which isn’t bad. YG is slightly below that.


    2. Jyp are quite weak too and their main vocalists are usually average but they have 15& that are their best vocalists. I think yg cares more about uniqueness than vocal techniques but jyp’s songs are very simple and doesnt require that much techniques which is why their main vocalists dont really need to be strong like sm.


  2. @ahmin3 Thank you so much for the analysis, I’ve only read through and haven’t listened to the performances yet, will comment later once I get to listen fully. But… just would like to point out that…

    “They may not always work effectively, as heard in “Lost Stars“, but he tends to find success most of the time with subtle changes in most of his covers. ”

    “Lost Star” was Taehyun and not Seungyoon?


  3. I thought he might be above average since he was thought that he might be better than Lee Hi. At first looking at his supported range, he seems to be better than the other idol baritones analysed but then he’s the same with Daesung lol i guess they’re pretty even😄

  4. I almost screeched when I saw these on my Facebook feed. LOL In fact I might have screeched a little..
    A narrow supported head voice range? Yas. Eb to G# is, like, 2 notes and a semitone?
    Reading this made me realize how rough his style really is. I hope he can find a happy medium in using the style he likes and treating his voice right. The words “pushing” and “throat” were prominent enough to make me nervous for him lmao.
    Oh, and hey, he got the rating I guessed for him! My little optimistic heart was holding on to the possibility of AA though.
    I’m glad the mystery of Kang Seungyoon was finally unlocked. Thank you so much for your hard work!
    I guess it’s Hayi > Daesung > KSY, right?

  5. I’m wondering that since in the analysis you said KSY can support up to Bb4 with Head voice, why doesn’t it count as part of his supported range since his range is Bb2 – G#4 (with head voice) ?


    1. It’s within the analysis, he is a baritone and he doesn’t produce resonance consistently at all and he can’t sing E4’s with consistent support either.


      1. Isn’t being inconsistent with resonance a trait that falls under AA. I’m not talking about his rating because I get why he’s A to AA but in general?


      2. Most if not all AA vocalists are consistent with resonance in parts of their ranges, the inconsistencies happen at the top of their supported ranges. Seungyoon is inconsistent with resonance, period. Finding moments where he produces resonance is a rare thing to do. For AA vocalists, they produce resonance consistently, just not throughout their whole ranges nor in every note.


      3. Okay thank you for explaining. I just read Taehyun’s analysis and are the three slashes because of lack of material or is he actually that inconsistent. I like the new archive thing header on top btw.


  6. Yes I love winner. And that note was only a G4 in Baby Baby I thought it was higher for some reason lol? I can’t wait for Taehyun though not rushing you lol.


  7. Yay, another baritone! Thnx for making his analysis, I secretly hope he and the other idols that were analyzed find this site :3


  8. Most vocalists who favors style over technique are somewhat bad, so besides Sandeul, who are others who favors style but still manages to have good technique?


    1. Ailee is somewhat stylistic, so is Baek Yerin and so is Naul. Style can be done well if a vocalist can find a happy medium between style and technique. The issue is people have a very superficial understanding of styles.


      1. Slightly offended at you forgetting Kyungsoo. Sandeul is stylistic? I thought his lack of musicianship. is one of his biggest weaknesses.


  9. Range wise, supported range without head voice for baritones falls somewhere within Bb2/B2 and Eb4/E4
    Inconsistent with resonance
    Even in their supported range strain and tension can be present
    Nasality can be present within the voice at times

    Ahmin, this is from the criteria page. I really still don’t see how he isn’t AA. I remember you also said before that ”note/note” means one or the other in the criteria area, but not the analysis. So Seungyoon would need either Eb4 or E4. He already has it.


    1. Inconsistent with resonance as in, inconsistent with resonance throughout their mixed voice range. All AA vocalists produce resonance consistently, just not in every note they sing. Seungyoon produced resonance less than 5 times in the videos I found for him. Also he has a lot of throat tension in his mix even within his supported range, more so than an AA vocalist. Seungyoon fits some of the criteria but not enough of it so that’s why he’s in between. Every single AA vocalists produces resonance consistently, just not throughout. Like most of the AA sopranos are consistently able to produce resonance up to B4, but become inconsistent with resonance above that though support is present.


  10. WOW. A new baritone, a new stronger YG idols, and kind of uniqueness again Lead is stronger than Main (daesung, him, minzy). And i’m a bit surprised he’s quite good, even he can use head voice almost up to C5, just a lil’ bit will. Hmmm… can i guess it’s head>low>mix? or quite equal for all? i read up there u said he’s above daesung, why? is it bcause he’s more support in low notes than dae?

    Btw, nice new design but just a bit confused here hehehe


    1. He’s overall better than Daesung, in his mix and lower range but Daesung has a better head voice. Oh sorry but you’ll get used to it!


  11. Random question but who’s better out of Block B’s Taeil and Seungyoon. I’m a fan of both groups and the groups are close so I was just wondering.

    Also, if KSY>Daesung doesn that make KSY YG’s best male vocalist or are there others that I’m completely forgetting about?


  12. Thanks for this. I had a good read. I expected him to fall under Average or Above Average but he’s on 2.5 xD
    Looking forward to Suhyun’s analysis.


  13. KSY said in a radio show that a doctor said his vocal cords are not good for singing. Can you tell if his problems can also be attributed to biological conditions apart from technique?


    1. I’d need more details because “his vocal cords are not good for singing” is very ambiguous and vague. I think if he means they’re unhealthy then it’s completely attributed to his vocal technique, since he tends to push his voice a lot and has a lot of tension in general when he sings.


  14. Hello~~ Thank you so much for doing these analyses. They are always so interesting! *thumbs up*

    If you have the time, I was wondering if you could give some commentary on Seungyoon’s latest Collaboration performance “Tenderness”? Although he was apparently nervous throughout so I’m not sure if it affected his singing…

    Thanks again!


    1. He was nervous? Was that because he had to sing more in Chinese than in most of his other performances on this show so far? He sounds pretty much fine, I don’t hear anything different from what it’s stated in the analysis. In the higher parts I hear a lot of chestiness and tension, but in this performance he seemed to be less challenged since most of the higher parts were sung by his duet partner compared to earlier performances.


      1. Likely. He mentioned that he normally makes some awkward gestures with his hand as he sang, but he was too nervous to make even those in this round, lol.

        He also mentioned that he has trouble with pronouncing “Yu” which comes pretty frequently in this song. So, that might be it?

        I feel like I’ve heard him singing in the lower range less than I’ve heard him singing in the higher range… is it because most pop songs tend to be of the higher range?


      2. Well yes and if he’s singing rock, he will be belting most of the time and with a group of tenor vocalists, it’d be unfair to make them sing as low as he possibly could, yknow?


    1. Copy pasting Ahmin3’s answer from OH when I asked before, I think it was originally answered here, on the blog, somewhere. Thank you again, by the way for the answer🙂

      For Sugarman:
      “Taehyun has support in the beginning, a bit too airy here and there but support is there. He is singing straight through his nose though. 0:30 I can hear now that because Seungyoon uses such a chesty mixed voice, when singing softer he tends to become slightly throatier but his transitions into what sounds like a head voice are actually pretty nice. 0:58 he tends to sing with a somewhat closed throat shaping, but he gets more closed on the Eu vowel. 1:09 he seems to push more with his throat when he sings E4’s but below that, around C#4 he wasn’t pushing too much and support was there. 1:22 all the tension on his shoulders, it’s so visible. F#4 and G#4. 1:25 somewhat nasal mask placed falsetto in this area of his voice, I’m not sure I’d call it a head voice anymore. 2:02 support on D4’s is there, he could be more opened. 2:14 F#4’s and G#4’s all in his throat. 2:21 Taehyun sounds nasal and closed still, he just sounds so shallow. 2:32 that run was so sloppy and he sounded so closed. Nasality carries through to his falsetto. 3:14 oh hey F#5. 3:16 he really seems to struggle with his mix, it’s so tight and pushed even on G#4. It was a nice performance overall but vocally there are more than a few issues that could be addressed.”

      For Koishikute (copy pasted from OH):
      0:30 ish onward, he sounds just of nasal but it’s okay, he was also slightly flat at first. 1:09 that doesn’t sound bad, he sounds fine in the beginning, he’s not as nasal now. 1:14 there was a bit of pushing/tension in that part, it may have been the vowel. He’s doing nicely with holding back the volume in his voice without necessarily closing his throat in order to do that. Interesting to notice the difference between Seungyoon and Taehyun, when Taehyun sings the beginning of verse, the line goes E3 E3 E3 B3 C#4, when Taehyun sings it, he sings it softly but he never transitions, Seungyoon sings the C#4 in falsetto, due to the fact that he has a lower voice, singing softly on C#4 (considering that his mixed voice is quite chest dominant) is hard if you don’t lighten up your mix…a tenor wouldn’t have to because it’s not high enough yet for one to use falsetto. 1:56 ~ 2:01 the placement isn’t actually bad in those notes, I am not really sure how I feel about his support because it feels like he us projecting well and placing his voice in his mask, but he is pushing the sound one with his throat for those E4’s and F4’s. 2:44 that F4 sounds really nasal and closed, I’ve been torn about how I feel about Taehyun around F4. He gets quite closed, Seungyoon is less closed than him and his placement is better. This song isn’t exactly in a challenging range for Taehyun, it is more challenging for Seungyoon but still they’re both doing okay. I wish the sound quality was better for me to be sure about Seungyoon’s tonal quality. Cool guitar solo breakdown lol 4:56 that note was closed, the transition wasn’t bad. Seungyoon on the other hand may be able to produce resonance, which is not something YG vocalists are often able to do …but he is from SuperStar K… Taehyun’s falsetto isn’t bad, but it also gets a bit nasal. 6:12 flat. Ooh is not a good vowel for Seungyoon, there I’m noticing more of a closed sound. 6:29 flat again. 6:45 that was all in his throat, very very throaty, very strained F#4 and G#4 I believe. 6:58 Seungyoon’s falsetto is throatier than Taehyun’s, Taehyun has bad posture. 7:10 ish the E4’s and F4’s, he is going back and forth with those, they sound tight in his throat, 7:16 the D4 had good placement, the vibrato was a bit slow but it doesn’t seem that bad. This was a long song, it felt like I was listening to John Mayer tbh.
