F#2 ~ C6 (3 octaves and 3 notes)
Bb2 ~ Eb4
Bb2 ~ Bb4 (with head voice)
- Strongest vocalist in WINNER
- Support is consistent throughout his mid range
- Mixed voice remains supported up to Eb4
- Some support can be carried up to E4, very inconsistently
- Able to use a connected supported head voice
- Able to produce resonance
- Lower range remains present even below where support is present
- Tends to push his mix with his throat
- Inconsistencies with support around E4 and above due to harsh approach
- Favors style over technique which causes him to be aggressive in his singing
- Tends to not open up his throat enough
- Resonance is produced rarely
- Nasality can be present in his singing
- Usually uses falsetto with a lot of pushing and throat tension
- Lower range below Bb2 is not used often, under-explored
- Lower register: His lower range mostly remains underused but decently developed. He has enough vocal cord strength in his chest voice muscles to be able to maintain tone throughout his range, although support seems to not be present often below B2.
- Mixed register: His mixed voice is mostly quite chest-dominant. He tends to push his chest voice into his mix as he ascends in range and is able to maintain support up to Eb4. Above that he tends to be too throaty and support becomes inconsistent.
- Upper register: At times able to use a head voice, mostly within a reasonably lower range. Tends to push too much air pressure into his upper head voice and falsetto range, causing him to sound strained.
Stylistically Seungyoon tends to draw his influences from a more indie and rock genre direction, as opposed to R&B or other genres that tend to be more run-heavy. Thus, it can be noticed that he tends to avoid doing vocal runs most of the time, with the exceptions being occasional soul songs or slow runs in simple R&B songs. The few times he’s attempted vocal runs, he tends to show a lack of ability to maintain proper breath support and smoothly connect each note in a run. Instead, he tends to become pitchy and sloppy due to an improperly used muscle memory. His main vocal habit is to add a lot of pressure into his vocal cords, which causes them not to be relaxed enough for him to have enough flexibility in his voice, resulting in his voice being somewhat slow. Examples of this include his runs in “Ordinary People“, as well as “그리워해요.”
Kang Seungyoon initially debuted as soloist after participating in the second season of Superstar K, in 2013. Shortly after, he re-debuted in 2014 as the lead vocalist of WINNER after participating in the survival TV show meant for YG’s next boygroup debut. His style is often very rock-oriented and he tends to show his skills as a vocalist, songwriter and instrumentalist by writing his own songs while accompanying himself playing his guitar. His voice is unique in the sense that while many other main and lead vocalists of idol groups tend to be high tenors, Seungyoon is one of the few baritones currently active as a main or lead vocalist in a male idol group. His voice is thick in tone and generally dark overall, enhanced by his rough approach in his singing.
His lower range can be quite well placed and connected, while maintaining a considerable amount of vocal tone. However most of the time, he tends to only maintain the right amount of breath support and connection of his vocal cords as low as Bb2, while losing the true consistent sense of breath support anywhere below that. His chest voice tends to be quite well placed in his chest with a strong development of his chest voice muscles down to Bb2, where he seems rather comfortable and consistent. Due to stylistic reasons, Seungyoon doesn’t often sing below B2, but the few times he’s done so it’s possible to hear a drop in sound, such as the G2 in “Lonely“, or a drop in support, such as the F#2’s in “Baby Goodnight.” Examples of him showing a good amount of breath support and connection in his lower range include the C#3’s in “Someone Like You“, the B2’s in “같이 걸을까” and the Bb2 in “반달친구.”
The most used and highlighted part of his voice is usually his mixed voice. Since WINNER’s music is written for 2 tenor vocalists and 1 baritone vocalist, it wouldn’t make much sense for their music to be too high or too low for either voice type. Generally sitting on a comfortable range from C3 ~ A4, none of their vocalists usually belt too high or sing too low. Due to this, Seungyoon is never truly able to explore his lower range much but tends to constantly sing at the top of his mixed voice. Most of the time, their songs are written in a mid-range for a tenor and slightly high range for a baritone, where Seungyoon is able to show support and maintain an adequate amount of technique.Up to D4 and Eb4, Seungyoon shows that he can maintain a relaxed approach and even produce resonance occasionally, as heard by the C#4 in “Someone Like You” and D4 in “Baby Baby.” Up to Eb4, Seungyoon is able to maintain enough breath support to outdo his bad habits and still keeps a relaxed enough approach in his throat, as heard by the Eb4’s in “당신께 쓰는 편지” and “시간을 거슬러.”
Above Eb4 he tends to use his throat more and although support may be present on his E4’s, it’s usually overshadowed by him not being completely relaxed and pushing too hard with his throat muscles, as heard by the E4’s in “Someone Like You“, “Lonely“, “그리워해요“, “우리 헤어졌어요” and “Ugly.” Above E4, Seungyoon has never shown the ability to maintain breath support at all and tends to use his throat almost completely. This can be attributed to his stylistic choices by drawing influence from the rock-genre. As a result, instead of using proper breath support while keeping his rock-style approach, he tends to push his mixed voice out with a lot of chest-dominance and throat tension, as heard by the F4’s in “恋しくて (Begin)“, “말할 수 없는 비밀“, “비가 온다“, F#4’s in “This Time“, “Wild & Young“, G4’s in “궤변 광란의 축제“, “0 + 1“, “Baby Baby“, “공허해“, G#4’s in “Je T’aime“, “Someone Like You“, and A4’s in “시간을 거슬러.” This is not to say that he hasn’t shown improvement over the years. Compared to his Superstar K days, Seungyoon has made very good progress in his breathing technique and being able to sing with less pushing around the D4 ~ E4 range, if contrasted to performances like “본능적으로.”
His upper register usually is a very lightly approached and supported head voice, which is usually well transitioned into when singing with less volume. His transitions become less smooth and he may end up switching into a falsetto when he goes from his upper mixed voice with more chestiness up to his upper register. This is caused by him using too much of his thyroarytenoid muscles that when transitioning into a more cricothyroid-dominant cord function, he’s using too heavy of an approach and switching to a much lighter use of his vocal cords becomes too abrupt, thus making him use a thinner airy falsetto instead. However for the most part, he’s able to use his head voice and is able to support up to Bb4, as heard by the E4’s in “우리 헤어졌어요“, G4’s in “Lonely“, the G#4’s in “시간을 거슬러” and the Bb4’s in “Je T’aime.” Above that, he tends to either use falsetto or simply use an overly excessive amount of throat tension and air pressure, causing him to sound tight and strained, as heard by the B4’s in “0 + 1“, C5’s in “Baby Baby“, C#5’s in “Je T’aime“, “아름다운 나비” the Bb5’s in “Tonight.”
In terms of overall technique, Seungyoon has a few issues with overly using his chest voice when singing higher, which can cause him to sound compressed and at times may cause him to go flat in pitch. Most of the time however he possesses quite a good sense of pitch with a good understanding of dynamics in his singing. Although it may become limited when he sings above E4 in his mix, he tends to be able to control his voice well below that. His vibrato also seems to be a bit of a problem, with signs of laryngeal movement as opposed to relying solely on a natural vibrato. This causes his vibrato to become quite fast and forced out.
Overall his technique is actually quite adequate for a young vocalist like him. His sense of technique helps him in his songwriting and his overall understanding of music help him communicate his lyrical content very well with his voice. He is very self aware and sings in a specific genre, which works with his current level of technique. For the future however, he would be quite limited to one genre, while the amount of tension and forcefulness in his mix can be quite damaging to his vocal cords and cause him to have issues if he does not change his approach in singing. For the future, learning to relax and balance out his mix would be the most important step in order to improve his overall technique.
As a songwriter, Seungyoon tends to have a lot of freedom when performing covers of songs. As he’s able to accompany himself with a guitar when singing, he has more control of how to perform the songs he sings. Since he has more control, he’s free to alter the melodies of songs as he pleases and he tends to add his own melodic ideas to many of his acoustic covers. They may not always work effectively, but he tends to find success most of the time with subtle changes in most of his covers. Harmonically speaking, Seungyoon tends to sing with a lot of chest-dominance in mix, so when harmonizing he finds it easier to harmonize when singing in his upper mix, than when singing in his head voice since then he lacks the proper blend if he has to harmonize with his head voice while someone else is belting, as heard in his cover of “Ugly” with Big Bang’s Daesung. Otherwise, his harmonies tend to be quite clean if the vocalists are matching in dynamics, as heard in “Sunday Morning” and “그리워해요.”
