Supported Range

F#3/G3 -C#5/D5 (without head voice)

F#3/G3-C#5/D5-A5/Bb5(with head voice)

Voice Type

Light Lyric Soprano


  • Supported head voice up to A5/Bb5
  • Can easily vocalize in the C6 and above range
  • Head voice up to G#6
  • Supported lower register down to F#3/G3
  • Strong connection to support
  • Supported mix voice up to C#5/D5
  • Occasional resonance up to C5/C#5
  • Strong sense of pitch
  • Capable of doing complex runs with good flow and pitch accuracy


  • Inconsistent with resonance
  • Above Bb5 head voice becomes shrill
  • Above C#5/D5 mix becomes very strained
  • Runs can sometimes be sloppy
  • Head voices seems to have decline since debut
  • Slight nasality


  • Lower register: Wendy’s lower register is fairly well trained and connected to the rest of her voice. Wendy is capable of supporting her voice as low as F#3 and is able to maintain a considerate amount of tone down to Eb3/E3.
  • Mixed register: Her mixed register has a very well supported sound up to C#5/D5. Despite the very solid support in her mixed register, Wendy however does not resonate often.  Wendy’s mixed register above D5 becomes very strained a tense due to a more chesty style of mixing.
  • Upper register: Wendy’s head voice has proven to be her most developed register. Wendy is capable of supporting her head voice up to A5/Bb5 with resonance and is capable of bringing her head voice up to G#6/A6. Wendy has also shown she is able to carry a whistle register up to Eb7.


Wendy has a style of singing that is heavily based in the R&B/Soul genre which is very much known for its complex and extravagant melismas, therefore, naturally, Wendy developed her ability to do runs. Wendy has shown she is capable of doing complex runs for example her runs in “Halo” by Beyonce as well as the Red Velvet song ”Red Dress” from The Red album. Despite being able to pull off fairly consistently she does have some off moments for example her runs in “Shake That Brass.”

Overall analysis

Before becoming a trainee under SM Entertainment, Wendy was a finalist at Koreaboo X Cube Entertainment Global Auditions in 2010. Prior to her debut in 2014 with Red Velvet, Wendy was very active vocally showcasing her vocal talent on youtube by uploading covers of songs as well as being apart of what seemed to be her school’s vocal ensemble. Now, as the main vocalist of Red Velvet Wendy is known for her rich, soulful voice and R&B style.

In her chest voice Wendy has a very strong connection to her support system this allows her legato to be very smooth and connected throughout phrases. She also has a very solid and full sound in the chest voice with very minimal airiness. Because of the fullness and solidity her chest voice has she can freely switch to a more airy sound without it being too airy and therefore lacking tone providing freedom with stylistic choices.

The full extent of Wendy’s lower register reaches Eb3 and the extent of her ability to support is F#3/G3 which fairly decent develop in the lower register for a Soprano. Because Wendy is able to support her voice moderately low she is fairly comfortable with phrasing in her lower register and is still able to maintain tonality most notably in “Be Natural.” Wendy easily phrases her way  down to an Eb3 without any major lack of tonality just a slight fry quality for style.  Wendy also shows off her ease in her lower register with Red Velvet’s performance “Wish Tree.” During this performance Wendy phrases many notes in the middle to higher part of her lower register with good support and tonality with ease. Wendy’s lower register is definitely a great assest to her and uses it =efficiently and with style.

Wendy’s mix extends to a high extreme of G5, however she only supports and resonates in the C5/C#5 range and occasionally up to D5. Although Wendy has very strong support and great connection to her support,  she doesn’t resonate often and is normally just supported with an open throat. This is most likely due to that she is not always completely opening the back of her throat consistently when singing in her mix for example in her performance of “Happy Me” with Huh Gak she transitions from a mixed B4 to a C5. The C5 is significantly more open and resonant than the B4 despite it being higher. Another example of Wendy’s inconsistency with her resonance within her supported range would be her C5 in her performance of “Dear Mom” with Tiffany. Although her C5 is considerably more open and supported than Tiffany’s it is still lacking in resonance due to the placement not being optimal. Wendy has also shown she is able to support herself up to D5 for instance in her performance “The Only Thing I Can Do” on Duet Song Festival. Wendy mix leans more on the chestier side of the spectrum and because of this when she goes outside of her supported range she ends up carrying too much weight. This is very apparent when she performs “Happiness” because after intense dancing she has to mix many Eb5s and because of the weight she is pulling up with they come out very squeezed and pushed.

Wendy has a very extensive head voice being able to take the register all the way up to G6 and also is able to use a whistle register up to Eb7.  Although Wendy’s head voice extends up to a G6 she is only able to support up to Bb5 which by pop standards is very good, definitely above the average. Wendy has shown she is very confident in this register because she will sing well into the 6th octave without shying away for example “Dumb Dumb Opera ver.” as well as Red Velvet’s high note battle. In many Red Velvet songs  Wendy’s head voice is at times a very staple feature for example “Red Dress,” “Something Kind Of Crazy,” “Candy” and many more. Wendy has very good control in her head voice as she is able to phrase head voice notes in the mid 5th octave with clear diction and support for example Red Velvet’s acapella version of “Sitckwitu.”  One of the main issues with Wendy’s head voice, similar to her mix, is openness. There many times in which she could suffer to be more open to create a larger more resonant sound for example her F#5 in “Shake That Brass.” She’s producing head voice, but the projection small and a little bit shrill due to her just not opening the back of the throat so the sound can resonant properly.  Also it seems as if Wendy’s head voice has declined since debut because before her debut she seemed to be able to support up to C6, however this could have been an inconsistent thing because she has not done it since. Overall Wendy’s head voice is fairly well developed really only have issues with maintain an open sound and supporting above Bb5, however in pop music Bb5 is more than enough.

Simply put, Wendy is a very well rounded vocalist with all of her register having a considerable amount of development balancing each other out fairly evenly. Her main issues lie in her inconsistency with her resonance and not always maintaining a very forward and open sound in her mix and head voice. However, this is all balanced by the sheer overall development of her register making those issues almost minor. Her greatest strengths are that she has a very strong sense of support, ease in her lower register as well as her head register and her ability to do fairly accurate runs.


Wendy’s style is heavily set in R&B, before her debut Wendy released many covers of her covering songs with a more R&B flare. She also seems to enjoy to do runs as she tends to sing songs in which she can show off her agility such as “Who You Are” by Jessie J and “Halo” by Beyonce.

  1. Yasss! Oh my god. Thank you so much^^. From what I’ve read, her registers are all pretty developed. She might be the best in the competent ranking because her registers are pretty evened out. It’s just the resonance that’s the main problem. But I think she’s close to Luna^°


    1. Truthfully everyone in the Proficient rating have evened out developed registers, because really..only thing different between her and JiMin is D5 and JiMin has better produced head voice and maybe a better lower register. Those girls in Proficient are all pretty even.


      1. Oh really? I thought that Wendy would have the best head voice in Proficient, huh. Okay. But every one of them has a certain slightly underdeveloped (not really) part like Taeyeon or Eunji has a not-very impressive head voice but Wendy does. Though she can’t produce resonance and they can resonate on D5 consistently


      2. Wendy’s head voice compared to TaeYeon’s and Jimin’s just isn’t as open it’s just support a bit higher. Also Taeyeon doesn’t have a “slightly underdeveloped” head voice, slightly under developed head voice would only being able to head voice B4/C5 lol. Out of all the girls in the Proficient area Wendy is the least open and has the least amount of resonance and to me that’s a big thing.

      3. Oh I see…so even Taeyeon’s approach is slightly better than Wendy’s. I guess her lack of resonance and openness is a major thing. I always thought that she sounded a bit lacking. Like, her D5s and C5s are nice but I just find myself liking the likes of Yuju better because of her resonance.
        But if Wendy was as opened as the other Proficient vocalist, would that be good enough to actually up her ranking or not?


      4. Yuju is only an Above Average or an Above Average to Proficient and her resonance is not that consistent either. No, actually would not be she would just be a better proficient vocalist really.


      5. Oh I know that Yuju isn’t as good as Wendy^^. I just like her notes better because of her resonance. But her MMA performances proved that she could be really…inconsistent. I hope that’s just a one time thing lol. If only she could go back to the days when she could hit good Eb5s to F5s. Or even if that was just a lucky thing to do, it still would be nice if she was consistent.


    1. Yep, and it’s been a while since her last non-RV performance. They really should, so we can see if she’s improving.

      Oh and thanks Pandayeu!


      1. Vocal line did record a singing tv show a little while ago, hopefully Wendy get to show off there. It will probably air soln


    2. that’s true. yuju and mamamoo are kind of overrated. it’s not that they’re bad, but they’re not “the best, most talented female idols” [says me, a mamamoo stan]

  2. I love Wendy soo much! Thank you :)) I know Wendy always mentions in interviews that she has stage fright and is always disappointed that she can’t showcase what she practiced. I hope in the future she gains more confidence and can really grow as a singer!

    I personally enjoy her voice and listening to her sing genuinely makes me happy. I really want her to be able to showcase her abilities through Red Velvet songs and maybe more stage opportunities. I really appreciate the thought she puts into her song covers and how she tries to bring out her emotions through the songs.

    I can’t wait to witness Wendy’s growth as a singer through proper practice, experience and age.

    Once again thank you!


  3. So wendy is the strongest vocalist in Red Velvet right? And she’s the strongest vocalist among female idol that debut on 2014, right??


    1. Yes, Wendy is definitely the strongest vocalist in Red velvet I never knew people thought otherwise…I’m not sure because i don’t know all who debuted in 2014.


      1. I think it’s only because some have insisted in the past that it’s Seulgi since “she’s more stable” (when they’re dancing)


  4. wow you’re back and post an analysis of wendy, that is great. it is really well written and informative. i read above, it says head voice up to G#6 and whistle note Eb7. does it mean she has not able to sing notes in between? which mean her 4 octave range is not full like kyuhyun’s


    1. No that isn’t what the means, she can definitely sing the notes in between there aren’t any gaps. Just because she hasn’t sung the notes in between G#6 and Eb7 doesn’t mean she can’t. Think of it like this if I tell you I have 5 eggs I definitely 3 eggs too right? Even if you don’t see them I definitely have 3 eggs because the only way I can have 5 eggs is if I have 3 eggs as well. It is the same thing for range, if she has G#6 and Eb7 she definitely has the notes in between.


      1. well, i didnt know octave work that way. i thought if it a whistle register, then it is allows you to have separate notes and may disconnect from the rest notes. thanks for your explanation


  5. Yaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaas.
    I was wondering if resonance would hold her back from Proficient to AA to P, and I’m glad it didn’t. I love the pictures you chose for her header, they’re really pretty.
    Thank you for the update! I’ve been excited to read this one.


  6. Thank you so much for this analysis! It’s so detailed and it makes me appreciate Wendy’s talent and skill even more ^^ I hope she gets to showcase her voice more often.

    Also, thank you Pandayeu and Ahmin for answering our questions about Wendy even before her analysis came out ^^


    1. I have sort of answered this question many times so I am not answering it again sorry, you’ll either have to look it up or just wait for the chart that is going to becoming out.

      Liked by 1 person

      1. That’s was harsh..but you must be really working hard and you are tired thank for the amazing analysis you’re always doing and all the workers…can you just copy and it uji the best vocalist in proficient category…last question pleas can someone change his voice somehow I hate my voice tone and sorry again🙂


      2. Honestly, I am just really tired of the “who is better” question because it has been answered multiple times and I am just tired of repeating myself we both are. So just wait for the chart and those questions will be answered because I refuse to answer a “who is better” question right now. To answer your question no. You can’t really change your voice only improve the technique. Really have confidence and he comfortable with your voice others probably think differently.


  7. This was a good read! I’ve been very interested in her technique since I’ve heard you guys say she sounded strong.

    One question though, has there been any improvement in the consistency of her resonance since debut, or has it been stagnant? I imagine it’s been stagnant but I have to ask, since it sounds like that’s her biggest drawback from being rated higher.


  8. Hi there
    First of all I just wanna say I really appreciate the analysis. Everything on this blog is just so informative and just great in general :)))
    I do have one question though
    So here is a vid of Wendy singing “Who you are” on 2 occasions. The first part is in 2014 while the latter is in 2016

    Is it just me or did her belts sound slightly throatier and tense in 2016? Is this a result of a decline in vocal technique/health or rather due to her inconsistency?
    Thank you very much


  9. Wow. It’s an early Christmas gift for me. Thank guys so much. Keep up the good work🙂. Ok So Wendy’s a quite well-rounded vocalist, has decent development of all ranges from lower to mixed and upper ranges as well as vocal runs. That’s good to hear. I just wonder how you would rate her vocal debut era and “Halo” era.


      1. About 2 years and she kind of jumping up to Proficient now. Do you think she’s improved pretty considerably? Hope she keep it up. I appreciate vocalists who have nice lower registers. They sound sexy somehow lol. One more question, vocal runs can be learned or it’s natural? Thanks ^^


      2. Wasn’t that 4 years? I mean before debut not debut Wendy. 6 years ago Wendy was like above average, 2 years ago Wendy was like AA to Pro and then she gradually moved to Proficient. Um I really say she just got better at what she was already doing and became more consistent.


      3. Oh sorry I forgot to answer about runs. Some people have a naturally ability to do quick runs and have a good eat and muscle co ordination to pull off complex and intricate runs, but you can most certainly learn how to do them and improve on it. But really some people are belters and some are runners, similarly to how some people are good at long distance running and others at sprinting.


  10. Omg finally Wendy is here. Thank you so much

    But, would she rate higher if she is more consistent in resonance and her headvoice hasn’t decline ?
    Also, will you also do Seulgi ? ^^


    1. I honestly don’t think she would actually move up a rating if she were to improve her consistency with resonance because then she would just become Jimin and Jimin is proficient as well. I am not even 100% if C6 was really a part of her vocal range, that’s why I mentioned that could have just been a one time thing because I have not found any other c6 for her but that one.


  11. I believe she can go below Eb3/E3 and improve her lower register in the future since she seems to appreciate that. Her first part in “Be Natural” slayed me hard. I want to see that side of her voice more often. I haven’t seen many light lyric soprano vocalists doing good at low notes (I mean in Kpop). Just wish SM would give her more chances to show off her voice with some of stylistic things, and guide and give her some freedom to do things like writing or composing like other companies.


    1. SM gives artists chances to go solo and showcase their songwriting skills if they have any but not without them being established with their groups first. Wendy is a rookie still, Jonghyun, Taemin, Luna, Kyuhyun, Ryeowook, etc. They all had lengthy careers before going solo.


      1. I don’t think OP necessarily mean a solo, but opportunitys to show of her voice on shows like immortal song, more OSTs etc. I know she’s been on some shows, but there hasn’t been alot of them.
        But then again SM has not been good with promoting RV in general, so…

      2. Thank you Ahmin, Cena. I mean, not only Wendy, other artists as well, the other RV members included. Promote them on some shows related to music. Have you watched the show called Run to you, where some YG artists were on?. That kind of show can help them get more recognition from the public. Show like YHS’s Sketchbook can boost digital… or just make covers of their sunbaenim’s/ other artists’ songs. They’re good but they also need people to acknowledge them. It encourages artists to become more awesome, (I’m thinking about Kyuhyun and Luna, they deserve more)…working on their musicianship, creativity.
