NU’EST’s Vocal Analysis: Baekho


Vocal Range

B2 ~ D5 (2 octaves, 1 note and 1 semitone)

Supported Range

Eb3 ~ F4/F#4

Voice Type

Light Lyric Tenor


  • Strongest vocalist in NU’EST
  • Support is present up to F4/F#4
  • Occasional support up to G4
  • Transitions into falsetto are done relatively well
  • Able to sing down to Eb3 with support
  • Rarely shows tendency to be nasal


  • Runs are usually sloppy and pitchy
  • Notes above F#4 tend to squeezed and sung with a high larynx
  • Unable to produce a head voice
  • Sometimes diction can be closed even within his supported range
  • Chest voice below Eb3 becomes weaker
  • Unable to produce resonance
  • Slight decline in openness since getting vocal nodules


  • Lower register: Not his most explored register but relatively decently developed. Support and good tone production are present down to Eb3 but below that, his volume drops a lot and his voice becomes a lot breathier.
  • Mixed register: Consistent support is present but unevenness in mix caused by a tight throat and a high larynx above F#4 cause him to strain most of the higher parts of songs.
  • Upper register: Unable to show a head voice. His least used and least developed register, he mostly favors mixing over attempting to use to use his falsetto. However falsetto transitions are done relatively well, with good pitch.


Baekho’s main vocal influences when it comes to more western music seem to lean towards R&B. With that being said, in his repertoire as a member of NU’EST, he rarely sings songs that challenge him in the agility department. When he chooses to sing covers of songs or when he sings solo songs, he does attempt to sing runs more often. These attemps are often not well executed because he is unable to stay in pitch when singing runs and hitting each individual note of a run, one by one. Instead not only does he slide through the notes, he slides faster than he can anticipate the notes he’s going to sing and generally falls off the key center of a song when singing faster and more challenging runs. This can be heard by his runs in “생일 축하해요“, “너네 누나 소개시켜줘” and “When I Was Your Man.

Overall analysis

Baekho debuted in 2012 as the main vocalist of boy group NU’EST. Throughout their careers, they’ve promoted in Japan and in Korea and have had mildly successful singles. Unfortunately due to lack of exposure, Baekho hasn’t been able to showcase his vocals with many solo performances on any TV shows focused on singing. His voice is generally thicker than his other bandmates, more so now than before his vocal nodule surgery. His voice still has a light quality to it and mostly sits in a higher range, like that of a light lyric tenor.

His lower range isn’t showcased much through NU’EST’s music but he sings generally within a fairly comfortable range throughout most of their songs. He isn’t challenged to sing low much, but the few times he’s done so it is possible to hear that his voice is more comfortable and developed above Eb3 than below. Whenever he sings as low as Eb3 or higher, he is able to remain relaxed, projected, and well placed. His voice stays present and his vocal cords connected, as one can hear in the E3’s in “생일 축하해요“, and Eb3’s in “Fine Girl“, “瞳を閉じて” and “무조건.” However below Eb3, his voice tends to lose volume and become breathier and less connected. He starts to lose support and his voice seems to be less developed below Eb3, where he sings less often. This can be heard by the Db3’s and C3’s in “瞳を閉じて“, as well as D3’s and B2’s in “Fine Girl” and “슬픔활용법.”

Even though Baekho is their main vocalist, within NU’EST’s repertoire, he actually isn’t challenged to sing the highest portions of songs as often as other main vocalists would be. As such, he doesn’t often try to sing too high nor strain his voice too much. He sings mostly within a reasonably comfortable range for his voice. His development of breath support is very consistent and stable, as he’s able to remain relaxed through his first passaggio. Up to F#4, he’s shown many times that he’s able to produce supported notes and not strain his voice much, as heard with the F4’s in “Beautiful Ghost“, “사랑없는 사랑“, “Hey, Love“, and F#4’s in “잠꼬대” and “Fine Girl.” Occasionally in the past, Baekho was able to carry support as high as G4, as heard in “이별복습“, but currently he seems to have shown a slight regression in his ability to stay opened even within his supported range. At times he shows tightness with support on his F#4’s, as heard in “어깨빌려줘” but for the most part support is consistent.

Above F#4, his mixed voice becomes tighter and more shouty. He tends to sound really squeezed and his voice becomes a lot thinner in quality. His overall support is not present above F#4, where he attempts to overcompensate for the lack of support by putting tension in his throat and pushing his voice out with more air pressure. The result is that he generally strains his voice anywhere above F#4, as heard by the G4’s in “Wait For You“, “야하게 입지마“, G#4’s in “나와 같은 차를 마시고“, “조금만“, “瞳を閉じて“, A4’s in “예뻐“, “생일 축하해요“, Bb4’s in “All Force One“, “사랑 없는 사랑“, “FACE“, B4’s in “When I Was Your Man“, “여보세요“, C5’s in “Beautiful Ghost” and D5’s in “여왕의 기사.”

His upper register consists of a falsetto. He’s never been able to show the ability to connect his vocal cords properly to produce the right amount of balance of his cricothyroid muscles and thyroarytenoid muscles in order to produce a connected head voice. Thus only singing in his falsetto. This is by far his least explored register, where many times he sings higher in his mix than he does in his falsetto. The few times he’s sung with his falsetto, he’s shown good control of his sense of pitch and his transitions are often relatively smooth, as heard in “너네 누나 소개시켜줘“, “사랑없는 사랑” and “All Force One.” Although at times his transitions can show a very noticeable drop in volume and projection, as heard with the C#5 in “조금만.”

In terms of his overall technique, Baekho is a consistent vocalist within his supported range. His connection between proper breath support and staying relaxed in his throat is quite consistent, although not fully developed. He is yet to explore the full extent of breathing deeper into his diaphragm, which causes him to not develop his voice more than he’s done so far. With that said, he also has a pretty clean sense of placement and doesn’t often place his voice in his nose. Even so, he’s still unable to place his voice forward in his mask with an opened enough throat to produce resonance. He’s mostly quite clear in his projection and his sense of dynamics is sensitive to each he sings. However his lack of control of his mixed voice and other registers cause him to be unable to produce a wider variety of dynamic changes outside his supported range.

As a vocalist, Baekho has remained quite professional about his singing over the years. No major declines nor issues have been heard, aside from him having vocal nodules. Even then, he respected himself and took the time out to rest his vocal cords. He’s yet to fully explore the extent of his potential as a vocalist and could improve in many areas that could guarantee him to further his career as a professional vocalist. Perhaps being given the opportunity to perform in TV shows such as King of Mask Singer or Immortal Song 2 could help motivate him to find an instructor who can help him develop his voice further.


Musically speaking, Baekho doesn’t often attempt musical changes in his vocal performances. He has done so, as one can hear by small melodic changes made to the cover of “Wait For You“, but for the most part he focuses on singing the song as it is, as well as he can. The few times he has attempted melodic changes were successful, even if the changes were minor. Harmonically, NU’EST is not known for their acapella performances but Baekho is able to handle his own parts in harmonies and blend his voice well with his duet partners, as heard in “Wait For You.”

  1. As always, great job, Ahmin. By the way, I wanted to ask about the openness issue in this vocalist that I’ve never heard about. How can openness drop as the result of vocal nodules? I thought openness was always about vocal tract or throat shaping, creating space in the mouth and such.


    1. I keep feeling a little bit of resonance is usually needed to get slightly better than average… it was a big reason I thought Hyunseong (Boyfriend) was going to be A-AA just from reading the strengths (although some other strengths helped). Actually, I dunno with guys, but I know there are Lyrics Sopranos like Jessica and Sunny who sometimes resonate but are still average, so I think it practically has to be a requirement to get out of average, unless maybe their supported range is just somehow wide but lacking resonance….

      1. Oh, so she is… but Sunny is still A with occasional resonance, and I think when Jessica was rated A she’d also already shown occasional resonance, so….


  2. How would you rank the boys in the average category.
    I think it would go something like


    1. At first I was like “who’s Jang?” Then I was like “oh Hyunseung.” Mhmm Hyunseung is definitely above Kevin but I don’t wanna spoil details that you’ll find out once the chart comes out. ;3


  3. Ahmin! I just want to ask. My vocal range is E3-F5 including the head voice but my tessitura is the same with Baekho. But some people said that I am a lyric baritone. Why is that? Although I knew myself I am a lyric baritone. And can a lyric baritone, under trainings, can develop into a light lyric tenor?
    Thank you and Godbless~


    1. E3? Are you sure you meant E3 and not E2? What do you mean by Tessitura? Dear, this is not Pokemon. You’re not going to train and evolve into a tenor, you’re a baritone and that’s it. You could sing as high as a tenor but you’ll be a baritone. I don’t know how to answer the question “Why is that?” .. Why is what? Why are you a baritone? I don’t know if I don’t hear you.


    1. Yeah I know what you meant and I’m telling you, that’s not a thing. Your voice is your voice, it is what it is. You don’t become another voice type through training. Don’t worry, I was just kidding. lol Well again I’d have to hear you to confirm the supported range and voice type aspect of your question.


      1. But is it possible for your voice type to change due to other reasons? Like Mariah Carey & Whitney Houston for example, their voices don’t sound like how it did when they were in their prime. Also could a voice be underdeveloped so it ends up being mistaken for another voice type? Like Jiyoon’s analysis says she’s a soprano but in the analysis it says she could be an underdeveloped mezzo. I’ve heard the same about Amber too.


      2. Mariah is still a soprano. A damaged chesty soprano who’s unable to mix because of her nodules, but a soprano nonetheless. Whitney turned into a mezzo due to abuse to her vocal cords because of her drug issues. Yes underdeveloped voices can be harder to put into a fach. Many of the weak vocalists can be hard to identify, I have more issues with underdeveloped females.


  4. I always thought he’s a baritone coz he kinda sounds and “looks” like one…?😄
    btw is Minhyun most likely weak?


    1. He seemed like he was weak while I was listening. Yeah I had the same problem! I thought he was a baritone because of his looks lol


  5. I’m always curious after reading these analyses as to what my voice type is. I’ve been in choirs that have placed me anywhere from Tenor 1 up to Soprano 1. I tend to have difficulty in my middle range when switching out of my lower register. My range is pretty solid though from E2 to C5, though I’ve managed D2 to E5 a couple times(and with lots of effort, depends on what vowel I’m using). Idk if I should post this here or elsewhere on the site, but I’ve always wondered about this since I usually just get stuck wherever.


    1. Did you say E2? Did you say Soprano 1? Are you a guy or a girl? I mean I can’t tell you your voice based off of this. I’m a baritone and I’ve sung bass, tenor and alto in choir before, so it can vary regardless of your voice type. I would have to hear your singing to help you.


      1. hey, i’m just curious.. I always thought vocal type is based on how low and/or high they can go, but you say even if you can sing as high as soprano or as low as contralto could, if you’re a mezzo, you’re a mezzo.. then how could you know the type of voice?? o.O thank you


      2. No, range does not determine voice type. Hwanhee can mix up to D5, that does not make him a tenor. Key can mix C#5, he is still not a tenor. Changmin can mix G5, he’s not a Soprano. Voice type is not determined by your full range, it’s determined by your natural range and where your voice naturally and comfortably sits. Even if you may be able to push your voice beyond its natural limits or even if you have great technique and can support really low or high, it’s where your voice naturally shines that determines your voice type. Also very importantly, it’s where your natural switches of registers, called passaggi, happen. So your chest to mix switch and your mix to head switch, those are the determining factors for voice type. Not where you scream and you can’t go any higher so you have to use head voice, but your natural switch. A lyric tenor switches to mix from chest around D4/Eb4 and from mix to head around G4/Ab4, a lyric baritone switches around B3 and E4. So there’s quite a gap between tenors and baritones, whereas Sopranos and Mezzos can overlap since their switch is smaller. A Soprano switches around F4/F#4 and F5/F#5, but a mezzo is like Eb4/E4 and Eb5/E5, but it can also be E4/F4 and E5/F5 depending on the weight of the soprano and mezzo, they can overlap and a heavier soprano or a lighter mezzo can have the same exact passaggi.


      3. Lol, yeah, E2, unless I’m reading this piano wrong? Idk, I never really used those terms before. And I’m a girl. Sorry for not mentioning it before. I would have to record a few things I guess? Gah, sorry I got super anxious out of nowhere, so now I’m uncertain how to respond. I really do appreciate the explanation you gave to RhiYeon though, I never knew any of that. I will get back to you on this…. probably this weekend.😛


      4. Wait you’re a girl? Then it’s probably E3. D3 and E5 sounds more correct. You might just be a Soprano and I’m sure you can go above F5, I think maybe you were singing E3 ~ F6 instead of E2 ~ F5.


      5. You think? Like I said, I’ve never really used those terms before, I’m just going off what I’m reading on the keyboard, which may be labeled wrong for all I know.


      6. Double posting, lol. Yeah, you’re right, and it’s labeled wrong. I took the opportunity to google what the notes on a keyboard are supposed to be labeled as, and these ones are off a whole octave. I thought there was something not making sense. Thanks for the input though! I’m gonna go hide somewhere in embarrassment now.


  6. I’m feeling conflicted. On one hand, I’m glad that Baekho is at least average since Nu’est is one of my favorite k-pop groups. On the other hand, I know he has the potential to become better. Well, he’s still pretty young; I guess we’ll see how he improves (or declines, but I don’t want to think about that).

    Though, I do find it interesting that he’s the main vocalist considering he has a pretty limited vocal range and k-pop tends to favor high vocal ranges.


      1. I see. Well, I hope he’s able to show off more of what he can do in the future a.k.a. IS2 or King of Masked Singer or just any future songs Nu’est releases. Thanks for the reply by the way.

    1. His exhibited range is pretty workable for most songs a kpop tenor might do, so it seems more like he hasn’t gotten in a high note battle? He doesn’t have a headvoice, and even Kyuhyun and Naul don’t support D5 in mix/belting, so it’s definitely not advisable that Baekho belt any higher than that.


  7. YASS finally NU’EST. So glad to know that he’s an Average, first thought he was a Baritone😄 Anyway, can you give a few comments on Minhyun please ? You say that he seems week but at what department ? Aron and Ren of course ignored since Aron barely gets any lines and Ren’s singing is truly poor (e.c. his final line in Overcome live was really cringy)


    1. He’s weak as in he’s unable to support his voice, he sings with a shallow unsupported tone. He has better legato and placement than Ren, but they both have similar issues with different degrees of underdevelopment of the voice.


  8. How did Baekho and Minhyun do in this clip? Especially Baekho’s high note at 2:21. It seems really strained to me and I worry he’s putting a bit too much of his throat into it.

    I hope the link works, I’m a little inept when it comes to this kind of stuff.


    1. Wow, listening to this performance I can now understand Minhyun’s lack of support in his singing. Dude sings just like me when he does those high runs, there is a very “jawy” feel when he descends. He has a bad breathing too, during his final “yeah” melisma he took a breathing. I think Ren has more “oomph” in his singing, as in for me, weight and support? Correct me if I’m wrong. I also think he tries to be too gritty. Aron always sings in a similar octave and that’s sad.

      That aside, do you think NU’EST is a group of tenors? Including JR?


  9. Hey, here’s another update video since NU’EST just recently came back. Compared to some of their other songs, Baekho sings a bit higher and I noticed there’s also an unsuccessful short run at 1:54. Basically, I’m wondering two things:

    1. Are all the high notes done by Baekho heavily strained and how did he sing in general compared to how he usually sings?
    2. Do any of the other members of NU’EST have any support?


    1. 1. There’s quite a bit of vocal strain but it’s not too heavily strained. It’s somewhat strained, but I’ve heard worse from other people.
      2. I can’t say I hear any support from any other member of NU’EST.


  10. Hey Ahmin, with NU’EST’s recent comeback, I’m reminded that I’ve always wondered if you’d analyze Minhyun, seing that he’s the Main/Lead Vocalist of the band along with Baekho, even though he’s quite weak (no support, plus sloppy runs and bad breathing technique).

    I actually think it’s needed to do him, since he does a lot of high notes, and a lot of fans are like “yay high notes = good singer” while others just consider the lead singers the best singers in the group.


    1. Well then we would have to analyze every vocalist who sings high by that logic, right? Like Eunjung of T-Ara who usually gets higher notes than Soyeon but can’t support almost at all. Nobody really requests Minhyun which is why I didn’t go through with his analysis, since we are trying to avoid analyzing weak vocalists as much as possible in order to give other more skilled vocalists in groups more recognition. I hope you understand. That’s not to say we won’t analyze weak rating vocalists who are soloists, but if the lead vocalist of a group turns out to fall in the weak rating and lacks material and requests, we just move on to other analyses for the time being.
