TVXQ!’s Vocal Analysis: Changmin [Newly Updated]


Vocal Range

A2 ~ C6 (3 Octaves, 1 note and 1 semitone)

Supported Range

D3/Eb3 ~ E4/F4

Voice Type

Light-Lyric Tenor


  • Very extensive mixed register, able to mix up until G5
  • Bright and relaxed falsetto/head register up until D5/Eb5
  • Able to produce non-nasal belts at time, with better projection
  • Able to somewhat support some of his lower range down to Eb3/D3’s
  • His throat and larynx stay more relaxed and stable, showing some support in his mix usually up to F4
  • Able to at times project his mix well, even with tension
  • Although strain is present in his mix, the mix is generally head-dominant, causing less strain than a chest-dominant strained mix
  • Able to produce head voice at times, rather a breathy falsetto


  • Nasality is quite frequently present in his singing, unintentionally
  • Notes below D3 show an excessive unnecessary use of airiness and become hard to hear
  • Lacks support and volume in his lower range
  • Tends to let his throat, swallowing muscles and tongue tense up on higher notes, making the sound come off whiny and tight
  • Falsetto register may at times be relaxed, but still lack the projection and placement present in his mix
  • Vocal runs are often imprecise and use a robotic staccato, lacking connection and flow
  • Falsetto, mixed and head notes tend to become very strained, pushed and tense the higher he goes
  • Intonation is at times off and inconsistent within one performance and in vocal runs
  • Uses a “Smile” technique in his belts, creating a high larynx and lots of muscle tension
  • Larynx isn’t always stable in his lower range
  • Transitions into head from mix aren’t very smooth
  • Mix is quite uneven, although headiness may strain the voice less, the tone in itself isn’t very versatile


  • Lower register: Not badly supported overall nor produced. Able to overall keep stability with the larynx and produced a non-breathy tone down to around Eb3 and D3. Notes below though may at times be overly breathy or just generally a stable larynx, but a quiet almost inaudible volume. The drop in volume takes away from projection and general placement. He also may at times lower his larynx to try and project lower notes, which is also incorrect.
  • Mixed register: One of the headiest and highest mixed registers amongst male K-pop vocalist. He is able to keep a stable larynx and soft sound generally up to F4 without much difficulty, but notes above tend to be shrill, tense, nasal and tight. Has the tendency to pull his mix up too high and strain his voice beyond his limit, producing a piercing unpleasant sound overall.
  • Upper register: The head and falsetto register tend to come together depending on the range he sings in. Generally switches into a falsetto if he’s switching from his mix mid-phrase or if he’s singing in his lower falsetto register, and above tends to produce a truer head voice at times and at other times a reinforced tense falsetto. At times may be able to easily go up to E5 and above, but the larynx isn’t stable and the sound is nasal.


Changmin’s voice should allow him to develop into a leggero tenor or tenore di grazia if he were able to truly develop the coloratura potential he has in his voice. His voice is so light and bright that vocal agility should be quite easy, however he shows more often than not that his runs end up being sloppy, overly staccato and incorrect in pitch precision. He tends to often not flow through his runs and sound sloppy in his runs, needing to work on a smoother flow between his runs and a more accurate precision.

Overall analysis

Changmin’s voice is one of the most noticeable and unique ones in K-pop. Member of acclaimed SM vocal group TVXQ!, he is able to stand out for his uniqueness not only in tone, but also in technique. Changmin’s voice sits quite high in range, but he isn’t anything more than simply a light lyric tenor, his true tone is still a manly tone, however due to the lack of chest in his mix voice, he’s been able to teach himself to sing in a much higher range than many other male K-pop vocalists, setting him apart from them in that way. His voice has a piercing, bright and light quality to it, lacking depth or fullness in tone, however.

The lower range clearly seems to be one of his least developed registers. Able to go down to A2, his voice lacks volume and projection in his lower range, only truly being able to be supported around D3 and above. Even so, at times his voice will be slightly unprojected and quiet even in that range, though proper cord connection may be present. On notes below D3, his voice will at times lose tone and become breathy, and at others, he will lower his larynx to fill his voice out as if to produce a tone he is aware he wouldn’t be able to produce otherwise. An example of this would be the performances of “Duet” by TVXQ!, where his C3’s are produced by lowering his larynx, creating a rather false and shallow tone, lacking true stability and a true support sound. However so, his larynx is generally stable above D3’s, with a more present, but light heady tone.

His voice truly shows itself in his mix register by extending up to the impressive note of G5. Changmin is one of the few male K-pop vocalists who is able to stay in such a high range constantly without great signs of fatigue over the the years. The problem with this, however, is that Changmin never truly developed his chest voice, even in his lower range, in his mix to produce a full and resonant sound. His voice is generally very light and heady throughout every register, lacking at true versatility and more often than note coming off as too bright and piercing. His mixing is heady and therefore uneven, unable to balance out, but also able to keep the larynx stable on notes like G4 and under, due to the lightness of tone produced. At times, in performances such as lives of “I Wanna Hold You”, he was able to produce  more opened G4’s, although not consistently.

The mixed voice however, takes a turn for the worse as he ascends higher in his range above G4, where many times Changmin will not be able to place his voice forward, will swallow the sound and lack projection. His throat tends to also close, the back of his tongue tensing up and his larynx raising, causing the sound to become thin, tight and nasal overall. He has the bad tendency of choosing to constantly sing songs that stay in this range, going high up above on C5’s quite often, straining his voice every single time he chooses to sing up this high. He does not tend to get throaty or push his chest voice up, but rather produce a heady nasal whiny sound which still will damage his voice over time.

Changmin’s falsetto tends to come out often when he does not transition properly between his mix and upper register, becoming slightly unstable and lacking the projection present in the mix. His mixed voice may be strained, but at least it projects, even if through his nose. His falsetto on the other hand, turns thin and breathy, not being able to truly cut through and project. Changmin will then force it to project by adding extra strain on his voice cords, pushing more air out and creating a very sharp piercing sound which he often uses in his mix and falsetto register.

His overall breathing isn’t completely incorrect, however he isn’t too mindful of the true intake of air he needs to support his voice. He never truly developed his chest voice to produce a truly resonant sound often, lacking chest resonance. He many times presents nasality in his voice, but that doesn’t take away from the support his voice does have overall when keeping the larynx stable through his supported range. One of his biggest issues is his “smile” technique. It seems as though Changmin has been taught that if he smiles while singing high notes, he will be able to sing higher and mix better. This is evident in many performances of “이것만을 알고가 (Before U Go)”, where notes such as F#5, tend to come accompanied by a smiley face. The problem with the smile technique is that it stretches the lips too wide, creating not only lip tension, but also raising his larynx, causing tongue and throat tension, and finally dropping his soft palate, a cause of his nasality. His vibrato is often used as well and at times it may be a tight larynx vibrato which squeezes high notes and rather than relaxing them, closes his throat instead. The speed of the vibrato hence, may be uneven at times.

Throughout the years, he’s been able to improve his intonation and stability, his placement also isn’t as nasal and he is able to at times lift his palate and produce a non-nasal sound. His vocal ability however is many times overrated due to just how high he’s able to sing, without actually looking at how he’s able to sing this high. Pitch accuracy in his runs, a fuller rounder resonant sound by taking away the “smile” technique and evening out his mix, and truly understanding where to sing with the voice he has would be the smartest areas where Changmin could improve his vocals. However so he’s still able to correctly deliver music he’s given by his ability to harmonize and blend his voice in, showing he’s more of a group member than a soloist.


Changmin shows a lack of ability to truly change music accurately in terms of notes and rhythm. He may at times sing things differently, but that will generally cause uncertainty and lack of confidence, which result sloppy runs, transitions and overall tone production. He does not generally try and change music, which shows an awareness of himself, however does not allow him to further develop him as a vocalist and musician.


Weak to Average vocalist

      1. Changmin is far from Kyuhyun’s level. You should actually carefully read the analysis. It doesn’t take an expert to comprehend simple words in an analysis that even middle schoolers can understand. All it takes is two functioning eyes to read.


  1. Wow this is amazing! I’m #1 Changmin biased for years and I’ve of course noticed his voice isn’t perfect, and this complete analysis of his voice is so detailed! It’s no surprise that he’s a weak-average singer tbh and it’s cool to know exactly why. 👏 So freaking detailed and thanks for so critically ranking. 👍👌 in terms of voice, what man would have an “excellent” rating? (It can be any guy you know of, not just kpop).

    1. It’s really hard, we really can’t think of any man that we know of well as “Excellent”, we know great male vocalists but Excellent? Not sure.


  2. I was wondering, there were some people on youtube arguing that Chanyeol and Xiumin from EXO is better than Changmin in terms of singing and they are in a very heated argument right now, is that true?
    And apparently one of them called you their friend, their name is ‘Salimatou Blade’. Do you know them?

    And one last question, one of them said Changmin is the ‘King of high notes’ but ‘Salimatou Blade’ said Chen is. Who do you think is the king of high notes in Kpop male groups?

    This is my first time commentating, so I hope you answer! Thanks.


    1. I wouldn’t know the true answer because none of them have very good vocal technique. All of them may fall under the same category as weak to average so without an analysis on each one of them individually, I can’t try and find out who’s better than who by a hair. I know who they are, but we are not friends, I really hate it when people quote me on childish arguments online. Anyway they are all not good and I don’t know who is slightly less weak than who. I don’t think anybody is the king of high notes amongst idols since they’re all straining at one point or another. Since all male idols strain at some point below C5 and only Kyuhyun can mix C5 with support, then it’s him. It’s most definitely not Changmin. Thank you for commenting!


      1. @ahmin3 I was reading this one other blog, and Chanyeol was ranked higher than Changmin. I think they were called K-popprofiles or something.


      2. Yes but I didn’t say that so do not quote me as if I did because I don’t like to spread wrong information around.


      3. As in, don’t go on Youtube claiming that I said something I did not about any vocalist. I did not ever analyze Chanyeol and Xiumin, I don’t know what their ratings are and I do not know who’s weaker between them and Changmin. I know the name “Salimatou” so please don’t quote me on things I’ve never said, I don’t agree with what was said and I don’t want my name associated with something I don’t believe in.


      4. Well, on EXO’S videos I see a lot of her comments, but I don’t talk to Salimatou. She’s popular on Youtube. But, I don’t get in conflict with her tho.


      5. Your IP Address and Sally’s were the same when you first came into the blog and when she came as well but right now yours has changed but it’s still nearby where her IP address was, so I figured you were the same person.


      6. Who happens to be Salimatou? Or whatever their name was lol because that’s the name Sally went by and that’s her YouTube page as well.


      7. Ah, thanks. I was pondering about the topic for some time. So technically, there is no king of high notes yet among male idols? I was actually thinking it might be Kyuhyun. About Chanyeol and Xiumin being better than Changmin, I’m kind of skeptical, as they would be around the same. But considering that Chanyeol has the rapper role in the group, isn’t around Weak to Average okay-ish? considering henry is weak and yet he’s not really a rapper.

        Oh, and I’m sorry for bringing up ‘Salimatou Blade’, I was kind of skeptical about whether she was telling the truth or not, cause nowadays, I see lots of comments in argument about you being their friend and such.

        Oh! And slightly off-topic! But have you heard Woohyun’s new solo song? I really liked the vocals in it, I was waiting for him to have a solo debut in so long!

        Anyway, thanks for taking the time for answering my question, and don’t mind about that commentator, I argued with her before and she was just plain stubborn, so her pretending that she’s not the youtube commentator is probably her trying to defend herself.


      8. That’s fine and I apologize for not being able to reply the lesson properly. My friends and my acquaintances are different people, people seem to confuse where they stand. I have not heard the song yet unfortunately. It’s okay, that commenter has been here for a while now and they’re nice and all but at first they came with a different persona or so they claim, their sister…claiming some messed up information to be true like voice types are pokemon levels and you can like evolve from a bass to a tenor as in tenor >>> bass and I was like mhmm.


      9. Since I want to come out with the truth, Salimatou Balde is my sister, shame to say it. I was trying to keep it a secret because the first time she came here on her first comment she was trolling. And, being annoying. So, Salimatou Balde is my sister. I’m her older sister Asmaou Balde. You may see me also a lot on EXO’s videos.


      10. Well sorry if I accused you but I’d appreciate it if your sister wouldn’t come up with random arguments online as if I were her friend or was on her side when honestly, I want nothing to do with the immaturity of fandoms. Thanks for telling the truth.


      11. As you can tell I’m the nice one, but only if someone is saying something bad about a person I like. I don’t really get in arguments that. My sister was trolling here because she told it was a dare or something.

        The argument with you was probably the most immature argument she had argue with people.

        My sister is very stubborn so it will take her a long time, any comment that she does not feel like it’s right she would comment, but only if she has facts to back it up. That’s only if I see her comments.

        But, it’s okay. Don’t worry I’m the nice one, just don’t forget that. Apparently she knows more about singing and dancing better than me that’s why I always ask you questions.( A LOT)


      12. Mhmm I see I see, well I’m sorry to hear. Don’t worry though, if she truly believes in some of the things she’s said when she came here…I wouldn’t think she knows more than you or enough to …let’s say “she has the facts to back it up.” Even if she believes she does so it’s not necessary for her to argue with every person who has a different opinion than her own but to each their own.


    2. Ahmin, qual a classificação de Dia e Haena (ambas do Kiss&Cry), obrugado, e obrigado por me ajudar e sempre estar disposto a tirar minhas dúvidas. xD


      1. Eu sinto mas eu não sei já que elas não forão analisadas. A Dia deve ser perto de competent, mas eu não conheço a Haena bem o suficiente.. Ela tá em um novo grupo né? Eu vi ela cantando e eu acredito que ela deva ser average? Eu não lembro agora.


      2. Eu já vi esse vídeo agora eu lembro, a maior parte é dela gritando C#5s. Average to Above Average at most.


      3. Oi, estou aqui pela Haena de novo, qual foi o desempenho dela no vídeo abaixo? Os falsetes foram bem produzidos?


      4. Assim falsete como você sabe não exatamente ideal, então mesmo que ela tenha um falsete assim de boa, não é voz da cabeça. O falsete dela é um pouco espremido. Eu não sei muito bem o que dizer dos Db5’s e C5’s dela no refrão “I (Db5)’m gonna SWING (C5)”…honestamente, os Db5’s não parecem ser ruins mas eu to ouvindo tensão nos C5’s…Isso na verdade e gravado em estúdio então certas qualidades do vocal podem ser alteradas e por isso eu não muito mais o que falar, por não ser ao vivo. Não foi ruim, claramente teve tensão “I’m gonna fly like a bird through the night”, essa parte é aguda de mais e eu não esperaria que ela conseguisse cantar essa parte sem tensão nenhuma.


      5. Eu respondo a outra, mas me perdoa eu não tenho tempo hoje para tanta pergunta e tem mais algumas para eu responder. Espera que já já depois dos meninos do 100%, eu vou analisar a Ben e a Dia então a análise da Dia vem logo e esse vídeo vai ser usado para isso.


  3. Do you think that Changmin himself knows about his vocal problem? I wonder is he aware or he actually thinks he is fine.


    1. I don’t know, just head voice? I mean he can, he just can’t support it. If he could support it, then I’d expect him to support a lot more in his voice.


    1. Hi there. Straining. He uses a high larynx, squeezed throat, improper breath support. Those notes are not extremely high if you mean the ones at the end of the bridge, it only peaks at Bb4. Changmin has been able to strain much higher than that, like the E5 or Eb5 from Mirotic.


      1. Thanks for replying! Haha, I see. I cannot tell the pitch; I thought those from rising sun are high coz he seems to be in so much pain (even much more painful than those from Mirotic)..

  4. But i always thought that changmin is above average at least and that he can manage his notes well or was that because as a group members can hide some of their weaknesses
    So what about yunho ?! People say that his voice becomes nasal sometimes or is he considered as a rapper ?! But his voice in November with love was good?!
    What if they try to pursue a solo career ?!
    And what is your thoughts about their performances together as a group ?!
    Sorry to disturb but as a non musician person .. I really wanted to know and understand because a lot of fans discuss that and I really don’t understand


    1. I don’t know rapping, this is a vocal analysis blog only. Yunho does become nasal and he has also a very limited level of vocal technique. They could probably pursue a solo career, being a soloist has nothing to do with vocal skill, as one can see from Britney Spears or Lee Hyori. I think TVXQ! as a quintet were a stronger vocal unit, but separated their weaknesses become more apparent.


      1. I know that’s why I asked if he is considered as a rapper because the blog didn’t analyse him yet so I thought that . I’m sorry^^’
        But how can they pursue a solo career ?! Isn’t being a soloist means that if they have a vocal flaws it will appear more then . And from what I understood changmin is considered between average and weak as singer and Yunho seems to be considered weak , or does that means if they tried to fix some of their weaknesses then they can success ?!
        Yes because the songs lines were divided into five so they completed eachother I think
        And thank you for making me understand more about singing and singers voices world ^^


      2. Well like I said Selena Gomez, Lee Hyori, Britney Spears are all soloists and they have very subpar vocal technique. Their appeal isn’t their vocals though, it’s their music and that would be the case for Yunho and Changmin as well if they were to pursue solo careers. Succeeding in their careers and being skilled vocalists are two things that are not related. Even if they improve, they might not be successful and even if they don’t, they could be very successful. No problem, it’s our pleasure. ^ ^


      3. Recently Yunho, Sungmin, Eunhyuk and Shindong did a song for the Korean military, and Yunho is made (from the how the lines are distributed) as main vocal of the 4. Do you agree with this arrangement; as in, do you feel like Yunho is stronger than Sungmin vocal-wise?

        Also, as a Cassie, I’m pleasantly surprised you enjoy listening to TVXQ (as said on the team page) even when they are not excellent vocal wise ^^

        PS thank you for doing all these analysis and Q&As~


      4. Well most artists aren’t excellent and TVXQ! had two of the top 30 make vocalists in Kpop so of course it’s enjoyable haha but I’m afraid I haven’t listened to this song so I can’t form an opinion.


    1. Key lacks proper support so he is singing through his nose and with a very tight throat throughout. The key of the song is different, so the range he’s singing in is about B3 ~ A4. There’s no news in Key singing like a tenor, he’s been singing like a tenor for years. lol Same for Changmin, he sounds very tight and whiny, placing his voice in his nose and not supporting properly so he ends up using his swallowing muscles too much, which close his voice. 1:44 that A4 was very tight. Let me get to your time stamps. I’ve heard this before. 4:12 D5 in mixed voice. 4:39 D5’s again. 4:43 D5 again. They’re singing a third below the original key, so Taeyeon/Seohyun/Tiffany hit F#5’s and Changmin’s hitting D5’s. Of course considering their already known supported ranges, those notes were all very strained and completely outside their supported ranges. There’s no idol or male Korean vocalist that we know of who can support D5’s consistently, or actually at all almost, so it’s understandable that those notes would be strained. It’s quite unfortunate for Changmin, he’s known for singing high but never truly has anybody focused on fixing his singing technique since to instructors it’s like “Oh he can sing high already, we don’t need to teach him.” Instead of understanding that a high range is good for potential but with the amount of tension he has, what good is that one octave of mixed voice above F4 all the way up to G5? It’s just a lot of tension and it needs to be addressed.
