BTS’ Vocal Analysis: V


Vocal Range

Eb2 ~ C6 (3 octaves, 4 notes and 1 semitone)

Supported Range

C3 ~ C4/C#4

Voice Type

Lyric Baritone


  • Strongest vocalist in BTS
  • The strongest sense of breath support amongst all members of BTS
  • Able to remain most relaxed within his comfort range
  • Able to transition into his falsetto with relative ease
  • Mixed voice is light and lacks pushing, not trying to sing too high with too much throat tension
  • Able to remain relatively relaxed up to C#4 and at times even D4
  • Sense of pitch has improved since debut
  • Sufficient support is maintained down to C3 in his chest voice


  • Tends to sing with too much airiness
  • Support is shallow and underdeveloped
  • Tends to lower his larynx too often when singing
  • Above C#4, he tends to sound harsh and flat
  • Tone production often becomes flat due to lack of forward placement
  • Lower range is relatively underdeveloped for a baritone
  • Unable to support his head voice
  • Falsetto is often too airy and lacks projection


  • Lower register: Due to the range in which BTS’ music is written in, he gets very few chances to showcase the true development of his lower range. Thus, his voice is relatively underdeveloped in his lower range for a baritone, where his tone production becomes muffled as he sings below C3.
  • Mixed register: His mixed voice is relatively light in terms of mixing, where he uses more head voice than chest voice when singing higher to minimize the amount of effort and strain on his vocal cords. Although able to sing above his first passaggio, his support is somewhat shallow and he tends to become tense above C#4.
  • Upper register: Able to transition into his falsetto with relatively ease, his overall tone production is airy throughout most of his voice but becomes fairly obvious as he sings in his falsetto. Able to produce a connected head voice even though support isn’t present.


Drawing less influences from R&B than many other idol vocalists in K-pop, V generally sings with an airy approach throughout his range and doesn’t often attempt singing vocal runs. The airiness in his voice makes it harder for him to be able to connect his vocal cords properly and control his pitch. This results in often sloppy runs when he does attempt them, in rare occasions. Perhaps aware that his voice isn’t necessarily very agile, as he lacks the correct muscle coordination to sing and bounce through different notes quickly, it is hard to find examples of V attempting vocal runs. The few times he’s done so, it’s possible to hear that he lacks clarity in tone and often sings runs by sliding through the notes quickly, without hitting each individual pitch precisely at the center of the note. This causes his runs to sound sloppy and pitchy overall, as heard in “Sorry“, “Little Star“, and “듣는편지.”

Overall analysis

V debuted as a member of the vocal line of BTS in 2013. Although not the main vocalist, the distribution of lines was even enough that he sang relatively often regardless of him being a lead vocalist or not. In most cases, idol groups favor vocalists with higher voices because most idol songs are written within quite high ranges, for males and females. Thus it is more common to see a main or lead vocalist of a group be a tenor or a soprano. In BTS’ case, V’s voice stands out because he is the only baritone singing with other three tenors in the group, although every rapper in BTS is also a baritone. His voice is thick in tone and slightly lower range, but still remaining relatively light in weight and sounding more like a lyric baritone than anything else. Although mostly written for a lower tenor range, BTS’ music is written within a relatively low enough range where V is able to sing alongside the tenors without too much stress on his vocal cords.

Considering most tenor songs generally are written above C3, V as a baritone gets very few chances to actually sing in a more baritone-like range most of the time. Thus his lower range below C3 is mostly underdeveloped and not very well explored, as he doesn’t sing that low very often. Down to C3, he has shown a clear enough consistency of tone production and projection, where both his vocal cords and his support work together to allow his chest voice to project with decent tonality. This can be heard in “안아줘“, “Oh Happy Day!” and “Someone Like You.” Below C3, however, he starts to lose connection and support, as his voice starts to become more muffled and breathier. This seems to be because his vocal cords aren’t developed enough as he sings lower, so his tone becomes less clear as he’s unable to project and place his voice in his chest as easily as above C3. This can be heard in with the Bb2’s in “If You“, A2’s in “안아줘“, G2’s in “Let Me Know” and the octave unison E2’s in “Someone Like You.”

His mixed voice is relatively well developed in terms of mixing and has enough support for him to be able to sing above his first passaggio, B3, without tensing up his throat too much. The range from C4 to D4 can be sung with some support as he’s able to remain relaxed and not sing only from his throat. This can be heard in “바람인가요“, “듣는편지” and “안아줘.” As he ascends above D4, he tends to use a very light mixed voice which is mostly head dominant, which allows him to push his voice with less tension than if he were to use a heavier and louder chest-dominant mixed voice. Nonetheless, the lack of support above D4 causes him to sound shallow and thin the higher he sings, as his voice becomes too light and oftentimes he can sound somewhat flat when singing above his comfort range. He tends to sing with a soft approach, but tension is still present in his throat as he’s unable to connect his breath support to his vocal cords in order to maintain his throat opened. This can be heard in the D4’s in “Something“, Eb4’s in “눈, 코, 입“, E4’s in “If I Ain’t Got You“, “Someone Like You“, F4’s in “I NEED U“, “If You“, “Butterfly“, F#4’s in “Let Me Know“, “Love is not Over“, G4’s in “Bang Bang Bang“, “안아줘” “눈, 코, 입“, “이사” and G#4’s in “잡아줘.”

His upper register mostly consists of a falsetto, with occasional moments where he’s shown the ability to use a head voice. Most of the time his vocal cords aren’t fully connected and he sings with excessive airiness, which causes him to sound thin and soft in his upper register, mostly associated with a falsetto voice. Although relaxed to an extent, a falsetto is not a register where true support can be present. Support would only be truly present if he were to use his head voice properly, however the few times V has shown a head voice have shown that he has issues with maintaining the connection of breath support with his vocal cords, where he instead pushes too much air against his vocal cords instead of allowing them to produce his head voice with their own strength and development. This results in a head voice that lacks control, by not being relaxed nor supported. This can be heard when contrasting his falsetto in “듣는편지“, “House of Cards“, “눈, 코, 입“, “Butterfly” and “Miss Right” with his head voice in “How Am I Supposed to Live Without You.” Interestingly enough he is the only member of the vocal line to be able to push his head voice all the way up to the sixth octave, higher than any of the tenors. This can be heard with the C6 in a high note battle during a fan meeting.

One of V’s main issues actually come from his tendency to push his larynx down when singing and not fully maintaining his vocal cords connected throughout his range. When your vocal cords aren’t fully connected, a lot of air can pass through causing the vocalist to sound breathy and soft. Stylistically this can work in many cases, but training yourself to only be able to sing that way can cause the vocalist to limit their vocal development. If the vocal cords don’t fully come together when singing, the vocalist will be unable to allow their vocal cords to become stronger and develop in terms of volume, range and muscle strength.

Adding onto this, V usually favors lowering his larynx and opening the back of his throat a lot more than necessary when singing even within a relatively high range. Most of the time, V’s voice can be perceived as quite deep but actually when a vocalist pushes their larynx down, it alters the natural tone of their voice and causes their voice to sound much deeper than it really is. This is often a stylistic approach used in soul music, that can be turned on and off at will. However for V it’s either this approach, airy and overly opened in the back of throat while not fully relaxed, or a harsh growly approach. Only having two options can be limiting to a vocalist if they’re unable to grasp breath support fully yet. Since V tends to push the sound of his voice in the back of his throat a lot, the direction of air from his voice isn’t properly placed in his nasal cavities, which makes it harder for him to understand mask placement and project his voice. As such, he tends to sound slightly flat in tone production the higher he sings due to lacking a good connection of proper breath support, an open throat and a forward mask placed sound.

When comparing V to the other vocalists of BTS, it is possible to hear that both he and Jungkook are the most relaxed out of all four of them. They have the least issues with tension and have a relatively decent range in which their voices are more or less supported, even though support may be shallow. However things can get tricky when comparing a tenor to a baritone, as being a baritone and having to sing in the same exact range as a tenor puts V at a clear disadvantage. Truthfully BTS’ music isn’t written for a high tenor range but it is still a challenging range for a baritone to be singing in. The passaggio is where the voice naturally lifts and the muscle coordination becomes slightly different, as sort of a bridge between a register and the next. The first passaggio is the transition from chest voice to mixed voice, while the second one is from mixed voice to head voice. A lyric tenor’s passaggi are usually around D4/Eb4 and G4/Ab4, while a lyric baritone’s passaggi are B3 and E4.

If V were to sing the same song as Jungkook for an example, but the key was changed to suit his voice as a baritone, he’d be able to handle singing above his first passaggio slightly better than Jungkook would. So the only true difference between them is that V has a slightly better grasp of breath support. However given the fact that V can’t simply change the key of every BTS song there is to suit his voice, he has to sing in the same exact range as the other three tenors. So naturally within the range that these songs are written in, Jungkook is the most qualified member to handle singing their repertoire. If V were to look into more solo singing opportunities, understanding his own voice type and embracing the true tone of his voice could help him develop his voice better as a baritone if he could sing in a range that’s natural to his voice. For future improvements, working on further developing connection between his vocal cords to be able to handle more dynamic changes, while developing his breath support could help V develop his vocal technique better overall. However for the time being, his current skill level is adequate for the type of music he sings.


V is not much of a risk taker when it comes to his vocals and singing. He tends to sing with one specific style and doesn’t deviate much from that specific sound. He tends to choose either a harsh growly sound or a soft airy sound, which remains the same throughout most of his vocal performances. He doesn’t often try to add his own melodic changes to songs and instead chooses to sing songs as they’re originally written. When given the chance however, he does like to add his own twist to his vocal cords and is able to blend his voice with others and even himself when adding layers of harmonies to his vocal performances. One example would be the added harmonies present in his studio cover of “Someone Like You”, where he sang the song in the key he felt was most comfortable for his voice, adding his own octave unisons and harmonies throughout.

  1. Which of the BTS vocalist do you think would has a higher chance of improving? Like you mentioned one of Jimin’s problems is tongue tension, is this an easier thing to fix than some of the issues the other members face?

    1. Without having a proper sense of support, establishing that first is the hardest thing to do for any vocalist who has established bad vocal habits and has been singing the same way for quite a while. Added onto the fact that they have a lot of tension, it would be even harder to grasp support. For Jimin who’s full of tongue tension, it’d be easier than for Jin who has absolutely no support. It’d be harder for both of them than for Jungkook who is a lot more relaxed than them. V would have a harder time than Jungkook as well cause he never gets to sing in a range that’s good for him. Again this is just guess-work, we won’t know until they try.


  2. Hi Ahmin,

    Just dropped in to say hi. I am ready to ask you the ultimate question for your fanboy heart.
    Duet from Jongyu or a cutiepie song by Vmin with very minimal vocal strain?

    P.S. What is the only thing cuter than a Vmin?


  3. So I’ve been wannting to ask this, I don’t know if somebody’s already asked ir before (if so, sorry)…. I was wondering, since V used to play the sax, can that be why he has a better grasp of vocal support? is the breath technique for playing sax at all similar to the breath support for singing?


    1. Oh nobody has asked that before. I wouldn’t say that the breathing technique used for woodwind/brass instruments and is similar, since people who play the flute don’t necessarily know how to support.


      1. Are their similarities between singing/brass than woodwinds? Although woodwinds are taught to breathe from the diaphragm, there isn’t much you have to do to direct your breath because there are so many keys. So while some notes may be the same (ex low F and middle F have the same fingering and you have to use differing force to get the different notes) there are not that many times to do that.
        While brass instruments only have 3 valves so more notes will have the same fingering and it breathing becomes more important to distinguish a note.


      2. Actually from what I’ve heard from people who play those instruments, the type of breathing for instruments with breath and singing is different. I’d have to check up on that as I’m not sure, but since the breath isn’t the same as actually letting your vocal cords vibrate, I wouldn’t say it’s directly related.


      1. Not OP but when I heard it I thought, wow this is going to be hard to sing live. Is it a difficult song or does it just sound like one? To non-professional me it sounds like a vocally more challenging song than BTS’ usual stuff. And it’s a shame V didn’t sing it in a more comfortable range for him, but it shows off his range I guess. Do you think it’ll damage his voice singing it on tour all the time, or can he hit those notes without straining too much (it sounds like he’s straining to me, but I mean, it’s really high). What’s the highest note he hits in the song? (Sorry about having so many questions)


      2. It is a difficult song and again it’s been asked about numerous times in the comment section. It’s a song with head voice G5’s, a lot of mixed G4’s and he’s constantly singing outside of his supported range with little to no success when it comes to proper technique. He is too young for this song alone to damage his voice, but he is singing in a range he’s not comfortable with a lot throughout the song.


      3. Thanks so much! So sorry that this has been asked before, I swear I thought I read the entire comments section. Also thank you so much for this blog, it’s been very enlightening. I always realised BTS had weak vocals but I never would have figured V to be the strongest among them, with all the shouting and growling and the electronics they used on his voice in the earlier songs (if he even got any lines) I really thought they were trying to hide that he couldn’t sing at all. But with the examples you provided I can hear it too, he sounds good when he sings in a comfortable range. Makes me wish they would use his voice properly.

    1. This song only goes up to C4 in the beginning, 0:16 it’s supposed to be A2 but he went lower like G2? I’m not sure why he sang the wrong note. 0:19 another C4. 0:26 the run was sloppy. 0:28 tense and tight E4. 0:33 more C4’s. He did fine within the range below C4, again nothing different from the analysis.


      1. I see, thank you 🙂 sorry for bothering with you another question but I was just wondering, have you checked out any of their Spring Day performances? As you’ve highlighted, many of BTS’ songs are written outside of Tae’s range, yet I’m very impressed by how he handled the chorus/bridge in that song, and at least to my naked ears he sounded awesome (minus the fangirl bias kekeke xD) Has he shown any improvement so far this year at all?

        Here’s a link:
        Tae’s parts are at 1:14, 1:41, 3:12, 3:32

        P.S: Thank you for always replying to questions, it’s quite rare that you come across someone who is actually knowledgeable and willing to discuss technical stuff with rookies like me, so thanks for that ^__^


      2. Hi dear. Well you see improvement only happens if one is to change their vocal habits and actually consciously try to better their technique. Since V just sings without knowing what to do to improve, itd be hard for him to show any improvement. Quite honestly he is singing exactly how he’s always sing and constantly staying close to the D4 ~ G4 range, where he’s unable to show proper support or sing without pushing. It’s my pleasure, I only really want to help, so as long as you want to learn, then I want to teach.
