Kim SoHyang Vocal Analysis


Vocal Range

Eb3 ~ A6 (3 octaves and 3 notes)

Lower register may extended down to D3.

Supported Range

G#3/A3-F6 (Including head voice)

G#3/A3-C6 (Not including head voice)



Vocal Type

Full Lyric Soprano


Due to her extremely well trained middle register and vocal endurance she is able to consistently belt with resonance and power in the upper 5th octave (E5-B5), this skill has been very much well showcased all throughout her career. She also has a very connected voice she is able to flawlessly transition between chest to head voice and head voice to chest with no noticeable breaks or cracks. She has the ability to do complex vocal lines without losing tonality and without losing speed. Because of superior breath control she is able to do complex vocal lines in one breath and sustain notes for very long lengths of time. Sohyang also can maintain a consistent column of sound and can sing with an even scale with no drops of support in the A3-F6 range, she is also one of the very few Sopranos who can stay within the Soprano range without vocal effort truly one of the best vocalist in Asia.


Compared to the rest her voice, her lower register is underdeveloped and lower notes can be unsupported.


Lower Register: Not well supported/quiet  below G#3/A3 lower notes can sometimes be lost due to the airiness of them.

Middle Register: Extremely consistent and amazing ease. 99.99% of the time supported. The Ring is almost always achieved in the A4-B5 range and resonance up to C6. Able to hold out notes in the upper fifth octave for long lengths of time and able to due to vocal runs in the upper fifth octave without losing resonance/tonality. Able to maintain dynamics in this register up to F#5/G5. Generally uses a balanced mix.

Head Voice: Well developed head voice that is connected with the rest of the voice. Very bright,full and vibrant able to maintain head resonance to F6.  Able to maintain/do dynamics in this register.

Overall Technique

Breath Control & Support: Amazing breath control and support. She is able to do vocal feats like Crescendo and Decrescendo with ease and complete resonance, able to stay in the upper fifth octave with ease and resonance no strain no pain. Dynamics are not a problem for her even in her upper extremes.Amazing transitions between head voice and chest. Superior control and support is sadly not carried down to her lower register as notes below G#/A3 can be not supported and just airy.

Resonance: About every time she opens her mouth

Mixing: When she started Sohyang used a headier mix in the E5-B5 range, but throughout the years she has adjusted to use a balance mix all throughout her mid range. She can willingly change the amount of chest she uses in her mix to make weightier sounds, but normally just uses a balanced mix.

Tone Production: She sings with a risen palate 99.99% of the time, so no true nasality. Her voice is very creamy and womanly though maintains the brightness of a Soprano. Has excellent control of how she uses her voice adding more or less chest to her mix depending on what she wants to convey/on the song. Her head voice has an extremely bright, vibrant soprano like feel to it, she is able to change the intensity of her head voice( from solid to floaty) at will.

Intonation: Pretty much flawless intonation, with only going flat about twice in her career.

Consistency: Extremely consistent


Sohyang has amazing musicianship and control of how she uses her voice to fit the style(from a more rock like sound in My World, to a more family friendly sound in Have Yourself a Merry Little Christmas). Her musicianship though, which mainly includes very high belts, high vocal runs, transitions from head to chest is not meant for everyone though. Common complaints about her musicianship is that it is too overbearing or just “too much” and that her belting can take away from the music at times and emotion can be lost. Though there are times when her musicianship is less offensive to people and they can genuinely enjoy her singing.


Excellent vocalist

  1. Hello, I found a great video about Suppoted and Unsupported

    In 12:28 they said that Ariana Grande and Christina Aguilera doesn’t use support, does it mean they have no supported range?


    1. This video lacks content, it’s mostly “here’s why Barbra is great.” It doesn’t even show supported vs unsupported, it shows inconsistent support vs more consistent support. No Christina and Ariana weren’t supporting in that specific range.


  2. Hey guys, just wanted to leave this here. God, SoHyang is really busy this year. She’s a Musician, an Author & a University Professor! :O That must be exciting! Could any of you translate what she is teaching? I’m sure there would be many others beyond just me who would love to know what she is saying.


  3. Also for anyone who hasn’t seen these, here is more footage of SoHyang & Park KiYoung back when they were in The Sound of Music together!❤
