As a vocalist, Hyunyoung takes influences from both R&B, ballad, and pop vocalists and shows that in her singing. For the most part, she is unable to perform difficult vocal runs with accuracy, generally becoming somewhat pitchy and sloppy in her delivery. Her runs are usually imprecise with pitch, with the rhythmic idea and separation of each individual note showing to be somewhat challenging to her. When she performs easier and simpler runs, she’s able to take her time and slowly sing each note in a run without too much trouble, as shown in “Stickwitu” and “나 가거든“. However, runs quickly become an issue when requiring more complexity in melodic idea and speed, such as in “If I Were A Boy“, “If I Ain’t Got You” and “천국“.
Debuting in 2009 as the youngest member and main vocalist of idol group Rainbow, Hyunyoung’s always been highlighted vocally in her group with adlibs and more challenging vocal lines. However due to Rainbow’s lack of exposure, Hyunyoung has been unable to participate in programs where she’d showcase her vocals alone such as Immortal Song 2 and King of Mask Singer and is often not highlighted as a vocalist. Her voice and tone are unique in quality due to her brassy style and bright vocal approach, making her singing quite piercing and her naturally high range be more easily showcased, as it stands out over others, such as her fellow Rainbow members.
Her lower range is one that stands out amongst the average female sopranos, where Hyunyoung not only is able to carry tone down to her lowest note, she is able to keep forwardness and chest placement in her lower range, allowing her to keep tone and project well below her supported range. She doesn’t often rely on airiness in her lower range and is mostly able to keep her vocal cords together while also relying on breath support in her chest voice. Down to G#3, she’s able to show stability and support, as shown in the G#3’s in “Listen“, “나 가거든“, “If I Were A Boy” and “애인있어요“, A3’s in “Black Swan“, and Bb3’s in “Something Special“. Below G#3, tone is often present but she has the tendency to become quieter and for her support to become more shallow, so fullness in tone becomes less present. However, she’s still able to carry some support below G#3, as shown by her G3’s in “If I Ain’t Got You“. As she descends lower in range, she may at times push her larynx down in order to reach lower notes, creating some tension in her lower range, such as the F#3’s in “참아주세요“. However so, that’s not always the case, as shown by the E3 and C#3 in “애인있어요”.
Her mixed voice is her register where most improvement can be heard overtime. Due to the nature of Rainbow’s music, Hyunyoung would often place her voice heavily in her nose and create a whiny piercing quality in her mix that would at times cause her to push her voice and sound quite shouty. Nasality was often an issue earlier in her debut, but over the years she’s been able to show that she can add less headiness in her mix and allow more chest voice to balance out her mix and lift her soft palate, opening her throat enough to even at times produce resonance in her mixed voice, as heard in the F#4 and B4 in “Listen“. Not only that, but support below B4 is quite consistent and she’s able to comfortably phrase supported notes around B4 and below, such as the Bb4’s in “Cha Cha” and the B4’s in “Tell Me Tell Me“. Above B4, however, she still is unable to keep a stable larynx and to fully support her voice, often relying on her throat and pushing notes out. Notes above B4, particularly C5’s, are often inconsistent with support and can either be light and easy, such as in “무조건” and “Wannabe“, or tight and somewhat shallow in tone, such as in “그녀에게 돌아가” and “Beautiful Tonight“, but above C5 her mix becomes almost completely shouted and she shows a lack of ability to properly control her volume output, as heard in the C#5’s in “Black Swan“, “If I Were A Boy“, “내안의 그대” and “A“, D5’s in “8282“, “White“, “Something Special“, “Hoi Hoi“, “Now“, Eb5’s in “그녀에게 돌아가“, “애인있어요“, and the E5 in “나 가거든“.
Her upper register is the most underdeveloped part of her voice, where she uses mostly an airy falsetto and is unable to keep her vocal cords consistently connected enough to produce a head voice. Even then, her transitions into falsetto often prove not to be too challenging, as she’s able to do so quite easily, such as in “Stickwitu” and “천국“. For the most part the issue in her upper register is the lack of true care to explore and take on this register. She rarely ever uses falsetto and when she does, it’s often very soft, airy and almost tentative.
Hyunyoung is a vocalist who’s able to control her breath management and dynamics well enough to take on challenging ballads and perform with enough accuracy. Often being able to control her pitch and her mixing, her issues generally lie on her inconsistency with keeping her soft palate lifted to eliminate nasality and her bad habit of often pushing her voice out too much with her throat instead of supporting, which often causes her to have a wobbly and unstable vibrato.
Overall Hyunyoung is a vocalist who possesses a lot of potential but is yet to be given enough opportunities to truly improve and showcase her vocal ability with more serious songs, despite having a 6+ career so far. For the future, not only would working on placement help her but truly engaging in her diaphragmatic breathing in order to keep her from becoming shouty in her mixed voice help her, but also emphasizing her vocal ability and engaging in more vocally focused programs, where she could potentially have more vocal growth overtime.
Musically, Hyunyoung is able to come up with her own musical ideas in her covers of songs and she can at times be daring enough to not only do them in studio, such as in “나 가거든“, but also live. However so, the delivery may not always come out with as much precision as she might have initially planned out in her head. Despite that she shows potential in being able to add her own flavor to songs. Harmonically, due to the image Rainbow portrays, Hyunyoung often sings a whiny nasal sound stylistically which she doesn’t always control and when singing in a group while harmonizing, her voice often stands out too much as she’s unable to blend correctly with the rest of her duet partners or fellow Rainbow members, such as in “8282“, “Stickwitu” and “White“.
