Voice Type

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.
