Jessica Jung’s Vocal Analysis

0. M Vocalists: Mid-range vocalists, 0. ML Vocalists: Mid-low range vocalists, Groups, Sopranos, Vocal Analyses, Vocal Ranges: 3 Octave Ranges, ,

Vocal Range

D3 ~ D6 (3 octaves)

Supported Range

G3/G#3 ~ B4/C5

Voice Type

Soprano

Strengths

Jessica produces okay, and at times decent, notes up to C5, and occasionally up to C#5 – rarely up to D5. On rare occasions, she has also achieved resonance and/or open-throat in the Bb4-D5 range. Amongst “Girls’ Generation“, she has the most developed chest register.

Points for Improvement

Jessica is very inconsistent when it comes to lifting her soft palate, therefore, her placement and projection are less than desirable. Though her pitch is between average and above average, she sometimes goes off the center of pitch on simple lines, and in worst case scenarios – entire performances. It is not uncommon for Jessica to go flat or sharp while singing high notes. She is also very inconsistent when it comes to resonance, and quite inconsistent when it comes to overall support, at times. Jessica’s best vocal performance was “Heaven“, with Tiffany, (6-7 years ago) where she belted a supported B4.

Registers

Lower Register: at times, she is supported down to G3/G#3, but more often down to A3 and Bb3. Below G3 Jessica voice is unsupported and airy, but the when supported the sound is solid, clean and nicely produced(“Europa“).

Chest Register: Jessica has one of the most developed chest registers in K-POP; when supported, the sound is very solid, forward, and has a very smooth vibrato (at times).

Middle Register: she is supported up to B4/C5, the majority of the time she sings, and up to C#5 at times. However, she is still inconsistent in the Bb4-C5 range. At times, she is able to support herself up to D5, albeit, rarely. When Jessica’s voice is supported in the middle register, it possesses a bright and slightly more womanly quality to it.

Head Voice: Mainly uses falsetto; does all right up until F#5.

Agility

Generally slow, but has produced fast runs in the studio versions of songs. Runs are in general, sloppy, not pitch accurate, and lack flow.

Overall Technique

Support and Control

Jessica’s support is average and inconsistent, even within her comfort zone she still has very frequent inconsistencies, which places her lower than others around her level. Above C5, and at times below C5, tension, shrillness, and flatness arises, preventing her from being able to move up in the KPOP vocal ladder. She also, at times, produces unhealthy and forced vibratos; that being said, she has shown to be capable of producing  ok and/or decent notes within the A4-C5 range – and sometimes up to D5.

Notes in the 4th octave (A4-B4) can be accompanied with nice support, decent placement and a clean vibrato. The majority of her open-throat and resonant notes lie within the A4-C5 range. At times, she can also produce ok to decent notes in the C5-D5 range, but more often they are produced in the C5/C#5 area. In the C5-D5 range, Jessica has produced opened C5s,C#5s, one D5, and a resonant C#5.

Sustained notes in the chest voice are normally supported nicely and have a very solid vibrato sometimes.

In her upper extension, Jessica fails to support her voice properly resulting in her producing a falsetto instead of a head voice. Her range goes all the way up to D6, but her falsetto is only acceptable up to an F#5 – above that her voice becomes airy and tight.

Her pitch could also use some fine-tuning as she has the tendency to go off pitch,  in live performances (even on  simple vocal lines) although her sense of pitch has improved.

Tone Production

Jessica’s voice is naturally soft and delicate, with and without a risen soft palate, but with a lowered soft palate the sound is more nasal and lighter. It’s more mature sounding, and fuller, when she vocalizes with a raised palate. Unfortunately, Jessica tends to sing with a lower palate, therefore we barely hear her fuller, and more mature, sounding voice. Besides, when she does decides to lift her palate, it’s on belted notes, and on rare occasions.

Her mixing is more on the brighter side, therefore her belts are very bright, light and girly sounding – even with a raised soft palate, although, at times, her mix is too heady and bright, causing the sound to be weak, frail and lacking in proper projection.

In the lower register, when supported, her voice is creamy and a little bit more rich compared to when she is belting  – which mainly just sounds bright and girly.

The tone of her falsetto is light and delicate, mainly because it’s falsetto is generally weaker than an head voice.

Improvement

Jessica has improved, slightly, in the B4/C5 area. Her larynx has also become more stable as she produces more acceptable notes, whilst vocalizing in that range, more frequently.

Musicianship

She has shown some musicianship in a few of her solo performances (“Almost“, “Someday“). At times she changes up her lines in live performances.

  3. By comparing Jessica’s latest album with SeoHyun’s solo album, it’s safe to say SeoHyun has a better head voice and Jessica has a better falsetto right? I know you want us to avoid questions comparing vocalists but this stucks in my head for a few days. Also it seems like Jessica has a slightly better lower range/ chest voice than the other GG members, a slightly better mixed range (more support on B4/C5) than SeoHyun, shouldn’t she be a tad better than SeoHyun, just curious?

    One more question about Sunny, if she occasionally does better than Jessica and Seohyun on mixed range, and a better head voice than both of them, it’s just the matter of consistencies than kept her from being ranked higher than them? Because I can clearly see she has a supported head voice up to F#5/G5 which none of them has.

    1. What’s a better falsetto? I don’t generally compare people’s falsettos because having a better falsetto isn’t much of an achievement and if Seohyun has a better head voice, she has a better upper register and period. They’re both inconsistent, they both have moments of showing better technique than one another do those can’t account to them being compared as it lacks consistency. Sunny’s lack of muscle stability, support and pitch are more extreme issues than Jessica’s or Seohyun’s. It’s not all about supported range.

    1. It’s shouty. It’s a studio note so the quality of the sound has more reverb to it and makes it sound more echo-y, but it’s just a bright shouty note, it’s not too shouty because of the brightness but to call it supported is quite a bit of a stretch.

  8. in the analysis it says she’s improved around B4-C5 but could you link any examples of this? I was just wondering because FLY/Wonderland doesn’t seem to really show that improvement, the C5 in FLY (studio and across her live performances) has been strained & high larynx, and Wonderland seems the same overall? I also wonder about her resonance because I can’t really find any examples of it. I’m sorry if I’m asking for a lot too, I’m just wondering really

    1. Actually the Dingo Acoustic version of Fly is one of the times where she had sung better within that range. The analysis cited that actually long before her solo mini album came out, so this improvement in the B4/C5 area is not referring to her mini album release at all. The best belted high notes video in the vocal range section shows her moments of resonance and I have no idea what C5 you’re referring to in Fly, because as far as I remember her belt in Fly is a C#5 which yes is strained as one would expect from Jessica. 4:44 in the best belted notes is a resonant C5, for example. Did you try watching these videos before you commented? I’m just wondering as well, since you said you couldn’t find the examples. I understand this analysis isn’t written like the more recent ones, but the examples and information is still sufficiently addressed and present in the content of the analysis.

      1. thanks for replying- With the dingo one I thought it mostly sounded just softer because it was an acoustic version(and a semitone down from the original so it only went up to Bb4 in mixed voice), I didn’t think it was that much different to the original. But I understand now with the improvement thing, and I watched the best belted notes- 4:44 didn’t strike me as resonant. With Fly too I did mean C#5 too, sorry. It’s just in the best belts video in particular, none of the C5’s and up really sounded that good to me, and even some of the studio B4s had tension on them. In her most recent releases, her C5’s haven’t sounded any better… I guess I’m just wondering what puts her into average to above average now, although she has support down to G3/G#3, so do many of the average singers and I don’t think inconsistent resonance on A4 and Bb4 is a reason to keep her in the category as some of the average vocalists are capable of this too.

        Like

      2. Oh that is true, you’re right. It is a semitone down, but the phrased B4’s throughout Fly are all supported, in studio and live as well. Sure they lack openness and Jessica does have inconsistencies with resonance, it’s not something she does often. None of the A to AA vocalists produce resonance consistently or even often, but they have been able to on enough occasions that we know they’re capable of it. Jessica is no exception to this rule. But Jessica does not support C#5, that’s been established. 4:44 if you can’t hear the resonance there, I honestly don’t know what to tell you. Yeah Jessica lacks openness, you’re right. She is inconsistent even within her supported range. I don’t know why you keep trying to put her down, as if these characteristics weren’t true for all Average to Above Average vocalists. All of them lack consistency, lack openness, lack resonance and can show tension even within their supported range. Which is why they’re Average to Above Average and nothing higher. Again this isn’t the first time you ask why she’s Average to Above Average and I’ve already answered this question to you before. What average vocalist has produced resonance on A4 and Bb4? Often enough? Aside from perhaps Sunny, or once for Tiffany, who else?

        It’s odd to me that you keep comparing her to other average vocalists, instead of looking at the bigger picture. Jessica can support up to B4/C5, there are inconsistencies yes but that’s the case with every other average to above average soprano. No average sopranos have C5 included in their supported ranges. None of them have produced resonance, albeit inconsistently, often enough. The reason Jessica and every other average to above average vocalist is in that rating is because they show characteristics of both ratings, inconsistently. Which makes them be in between, they have shown the skill level of both ratings, so they don’t quite fit on one or the other. Average vocalists have not shown characteristics of above average vocalists often enough at all. You keep comparing Jessica to the average rating vocalists, instead of comparing her to other vocalists within the average to above average category who all show similar characteristics as her. I just don’t get why you’re trying to put her down so I’m going to repeat what I said before to you. By your logic, every other average to above average vocalist should also be moved down to the average category due to their inconsistencies. You’re making it sound like Jessica is rated as above average and she is not. If she were, then it would be wrong because she barely produces resonance and above average vocalists have at least a more 50 ~ 75% ratio of resonance being produced. Even Above Average vocalists don’t produce resonance THAT consistently. I think you are looking too deep into Jessica and not looking at the whole patterns that we follow within the ratings for each vocalist.

  9. I think you’ve confused me for someone else, I didn’t compare her to anyone? Nor have I commented before & I’m not trying to put her down that much I was just wondering.

    1. Your IP Address matches the same IP Address of a user who also commented on the Jessica analysis September last year. It’s kind of an odd coincidence for both of you to have the same IP Address, both to comment on her analysis only and nothing else, and the fact that both of you feel as though Jessica should be rated as average as opposed to average to above average. Forgive me if you’re not the same user, but there were a lot of similarities so I couldn’t help but to think that you were the same person. ChoA can’t produce resonance and IU maybe produced resonance like once, I wasn’t the one to analyze her so I could be wrong but I did make her vocal range video. You didn’t upset me, I was just going in on detail when it comes to explaining why she is rated correctly. Again with the things you mentioned, all other A to AA vocalists would theoretically be rated down as well. The other user compared her to U.Ji and Tiffany so because I thought you were the same person, I said that. Looking at the criteria and other A to AA vocalists, do you see why Jessica matches that rating?

    1. 2:06 There’s nothing resonant about her C5. The vowel is really tight and closed, for absolutely no reason. There is no reason for her to sing an Oh vowel with such a closed throat but she does it anyway and it frustrates me. The 2:20 G4? Yes it’s supported.

Roj, I think I made a very specific point to you that I don’t like multiple videos posted with a general question “What can you say about it.” You’ve commented here enough times that you should have learned some things by now and I expect that you could be more specific with your questions, give me some time stamps and show me you were thinking of certain parts as you were listening to these. Cause with a general question like that, you’re gonna get a general answer. And I don’t mean this personally, don’t take it harshly. I just need to let you know, if your question is so broad, my answer will be broad too.

      She is really pitchy throughout Love U, like constantly flat. Yeah, I hear nothing new on either performance.

  27. Hi. Jessica has been my favorite member of SNSD way back when she was part of it. I still support he up until now. Recently she released her new album called “My Decade”. I just want to ask on how she did here in this performance.

    Did she supports the verses of the song because she sings softer compared to usual. I know that’s the way the song was supposed to be but did she support especially the notes at 0:26 , 1:49-1:51, 2:09 and 2:15.

    And I think something happened in 1:55 but I don’t know. I just think there is because of her expression.

    And is there support at her high note at 3:28.

    Also is it true that she regress in singing? Some people said that she did because her voice was stronger back then. I don’t know if its true but I think she didn’t. Another thing, if Jessica can produce resonance will she be able to rank higher, maybe an Above Average vocalist?

    1. Please avoid posting videos without time stamps if you have specific questions about high notes or such. This isn’t live, she is barely even doing a good job at lip synching. She is just moving her lips along to the track, they even have Park Myungsoo’s voice playing in the background. She is doing as well as she was when she recorded this because this is the audio we’re hearing actually.

  39. innocent question, i’m sorry if it’s too dumb.

    is it possible for some to have a very well developed register but still struggle with support? i mean, isn’t support required for you to proper connect and project through a register?
    i’m asking cause jessica’s analysis says she has a pretty good chest register but her support is less than desirable and she starts losing it in Bb3 at times. and also cause every other vocalist who has a developed register also carries support to difficult notes (like chen’s chest voice, which starts supporting in A2).

    it’s an honest doubt which i have wondered for a while. so, in this case, how is the development of a register linked to support?

    if you could, one day, please make a vid about chest voice, i love your videos ❤

I think that this isn’t the best quality of a fancam, there’s too much bass and it’s hard to hear when everything is loud but the parts where her voice is clear, I hear support with some tightness, some nasality, then some moments of openness depending on her vowels. Things Jessica is known for I believe.

    I really love the more recent analysis you guys have done, I feel like they are more in depth, show far more examples of the point you’re trying to make, etc. I think you guys are going to make another good job with this one when it gets rewritten.

    Just a curious question about mixing in general (and I guess about Jessica’s mixing). Still trying to figure out my way around it, so sorry if what follows is pure bullshit.

    Would you say that, in general, Jessica mixes a lot more “head” than someone like Seohyun?
    I’m asking because it’s obvious that, for example, Tiffany mixes a lot more “chest” into it, it’s very tangible and obvious when she does it. But for Jessica and Seohyun, I’m a bit more conflicted.

    Jessica has a very (naturally) airy, delicate and sweet voice – even within her chest voice (in my own opinion). Seohyun on the other hand has a very warm and almost deep tone, sort of/kind of “mumbled” (well I don’t know if you guys will agree with that), yet I still feel like Seohyun mixes more “head” than Jessica does, it’s just less obvious because of tone differences? Does that make sense or is that wrong, objectively speaking?

    Thank you!
    Keep the good work.

    1. Wait, I don’t quite understand what you are trying to say. You said in your first paragraph that you believe Jessica mixes more head than Seohyun, but in the second paragraph you said you believe Seohyun mixes more head than Jessica…doesn’t that…contradict?

      Anyway, both of them are pretty much the same, but SeoHyun has more of a projection issue than Jessica which is that “mumbled” or, more accurately, “muffled” description comes from. I feel like you are confusing Jessica’s singing style with the actual development of her voice. Jessica’s voice is not “airy” she may sing airy, but her voice is definitely not airy. She definitely approaches her singing lightly for stylistics purpose to give off this more delicate and dainty sound, but she definitely doesn’t have an “airy” voice if that makes sense. Also that being said, Jessica does not have a very powerful voice anyway which is fine lol.

      But yeah, Jessica and Seohyun pretty much mix in the same way with Jessica having more issues with keeping her vowels open and SeoHyun having more issues with making sure she is projecting.

      1. So sorry, I suppose the wording was really confusing!

        I am no expert (that’s the issue really), but to my untrained ears who are trying to learn, I would say that Seohyun mix is headier than Jessica’s, but it might not be as obvious because she has a deeper tone than Jessica and sort of a muffled sound.

        Like… I would say that Jessica’s mix is BRIGHTER but not necessarily more heady, if that makes sense? But I’ll totally trust your expertise if you say they both mix similarly. It’s just difficult sometimes for me to really grasp these things when tone and stylistic singing styles can get in the way.

        I do agree with the issues you’ve mentionned. My intention wasn’t really to say one is better than the other or whatever, but trying to understand more about mixing while comparing them.

        Thank you for the answer!! 🙂

    1. I just reread the analysis, and no one is giving credit for being nasal. In addition, nasal inflections will never be the biggest issue because the solution is dropping the jaw a little lower and opening the back of the throat as if to say “ahh” like a baby. Nasal notes don’t destroy a person’s voice; strained notes do.
