Davichi Vocal Analysis: Lee HaeRi [Newly Updated]


Vocal Range

C#3 ~ B5 (2 octaves and 5 notes)

Supported Range

A3/Bb3 ~ F5/F#5

Voice Type

Light Lyric Soprano


  • Very well trained middle voice, support up to F#5
  • Almost never strains
  • Optimally resonant in the A4-Eb5 range very often
  • Great pitch, rarely goes flat or sharp
  • Proper tonality is present at almost all times
  • No “weak” registers
  • Very round and full resonance especially in the A4-Eb5 range
  • Decent vocal stamina, can phrase mid mix notes(C5-Eb5) without sounding tired


  • Sometimes tension in either the jaw or the tongue can arise cutting resonance
  • Resonance in the E5-F#5 is not as large as in the A4-Eb5 range
  • Vibrato can sound uncontrolled and fast on sustained notes
  • Lower register loses much of it’s tonality below A3
  • Head voice approaching the G#5/A5 area is strained
  • True head voice is not used
  • Underestimates the amount of breath needed to sustain notes/phrases at times leaving her sounding out of breath at times.
  • Vibrato can be lost on sustained notes
  • When she does runs they come out messy


Lower Register: Her lower register is very average, her voice below A3 loses pretty much all of its color and just becomes airy, cloudy, and shallow sounding. Above A3 her voice still lacks a full resonant sound though she is supported.  The sound is more on the comfortable, neutral larynx side than it is full on the support, full sound side. Unlike some artists she doesn’t lower her larynx too much in the lower register to create an artificial fuller sound.

Middle Register: Most well-trained part of her voice and probably one of the best in Kpop. Very resonant, full, and rounded sound in the A4-Eb5 range. In the E5-F5 range she is still resonant, but the sound isn’t as full or as round as it is on the upper fourth and lower fifth octave notes. Resonance on F#5 is rare, normally is just supported. Decent vocal stamina in this register as she is able to phrase mid fifth octave notes without sounding tired. She also is pretty good at doing jumps between notes without loosing pitch. Pitch in this register is normally spot on, but sustained notes can become a bit under pitch; mainly because she is running out of air.

Head Register: Up to F#5/F5 her falsetto is fairly relaxed, but the higher she goes the more she pushes with her throat causing her falsetto to be strained. This register has fairly average production, so in other words it is not resonant, but also isn’t very airy.


Because HaeRi is a Ballad singer and focuses more on phrasing and the deliverance of emotions and she rarely ever plays with fast or elaborate runs. The ballad singer’s main focus is that their song has emotion and that a message in conveyed. HaeRi does this by using different kinds of phrasing. Watching performances by HaeRi one can tell she puts a considerable amount of effort in the way she phrases her verses and expression. By using different kinds of volumes and with the assistance of the instruments HaeRi can create an array of different atmospheres within one song.

Overall Technique

HaeRi is one of the best and most consistent vocalists in K-Pop when it comes to resonance and support in the mixed voice. Her mixed voice is definitely the register she has taken the most time to develop and train. Her other registers relative to her mixed register are quite underdeveloped and need some TLC, however she uses all three of her registers effectively in her singing.

Out of the Davichi Duo HaeRi is definitely the more skilled one. In Davichi songs she normally takes the more demanding lines, adlibs, and harmonies while MinKyung stays in more comfortable and unchallenging area which in turn does not help MinKyung improve at all. Some examples of this would be Davichi’s performance of “Maze of Love”, where during harmonies HaeRi is singing the higher harmony and during the bridge HaeRi belts a resonant E5 while MinKyung carries on with the chorus. Very similar to this would be their performance of “Do You Know”, where HaeRi belts a resonant F5 and MinKyung again carries on with the chorus. However, this is just how Davichi works and they have been doing this kind of arrangement since debut so obviously it works for them.

HaeRi has fairly good stamina in the middle register, therefore she is quite capable of phrasing mid to higher 5th octave notes without sounding tired or losing resonance. She demonstrates her vocal stamina very well in her performance “빗속을 거늘며” . In that performance during the ending she stays well within the C#5-F#5 range producing many resonant and supported notes. She’s able to stay in that area without sounding tired because she is using her diaphragm for support and power instead of her throat like many idols and singers in general do. Her lighter mix also attributes to her being able to stay in that range with little effort.

Though her mix is very well trained, it is not perfect. Certain vowels prove to be a bit of challenge mainly the Oo vowel or “으”(eu) and “우”(oo) in Korean. This vowel normally poses difficulty for singers because even though the back of the throat is in a more desirable position, the way the lips are contorted make it awkward. In her performance “보이지 않는 사랑” she switches from “나”(Na) which is an open Ah vowel to “우는”(Ooneun) which is an oo sound. She was resonant on both sounds, but there is less resonance and a little bit more difficulty on the oo vowel sound. Not only does a singer need to be resonant, but he or she also needs to make sure all of their vowels are uniform.

HaeRi rarely to never strains in the mix register because her supported range goes up to F#5. Only way HaeRi would strain, aside from just having off days, would be if were to tackle the G5 and above range, but as of right now how HaeRi does on notes above F#5 is unknown because she has yet to do anything above that. Because of her not going above F#5 it’s pretty safe to assume that HaeRi knows her limits and her voice. She probably knows she cannot support G5/G#5 so she doesn’t even attempt it.

Her lower and head register compared to her mixed voice are quite lacking in development. Her lower register below A3 lacks projection and solidity, however she has done comfortable G3’s. Her lack in development in the lower register might also be due to her style. When HaeRi does lower notes instead of trying to support and place them well in the chest she makes the quiet and airy to create a sense of sadness or breathlessness. There are definite signs of discomfort when she phrases low notes especially below A3. Her head register is also lacking development, as she rarely uses this register as well. She has a pretty relaxed falsetto up to G5 but above that she pushes her head voice creating a very tense and strained sound. Though her falsetto is not airy, it isn’t resonant which means she has a lack of connection. Despite its production, she accesses her head voice quite easily.


HaeRi’s musicianship does not center around elaborate and fun runs, but more on the beauty and deliverance of phrasing. She plays with many different kinds of phrasing styles to deliver a variety of moods and atmosphere. She normally phrases softly and breathy and then gradually builds it up towards the end of the song. As a ballad singer, how she delivers and how people interpret their singing is extremely important. Not only does she play with different ways of phrasing but also different kinds of dynamics. She goes back and forth between piano, mezzo forte and forte sounds a lot in her performances. She demonstrates many different dynamic plays and phrasing in her performance “I love you”.

    1. Please in the future don’t ask questions about non Kpop singers. I’ve seen that video before, all I hear is pushing and a high larynx from the other lady so no, not resonant at all.


    1. 3:02 I didn’t quite like that one because of the aye vowel. 3:19 same thing. 3:23 this one was better. 3:32 this one was the best so far because she got to breathe, the 3:44 one was nice too. Her sustained ones can be a bit pushed and the vibrato is too shrill.


  1. Good Evening and this is Haeri’s Live spoiler MV of her new song , which will be released few hours later. There are two episodes here in this video (2:02 & 2:37). For it is the first live video of her new song, how do you think of it? And how about these high pitches here? Many thanks!


    1. There’s very little tension when her vibrato comes out but otherwise she sounds really well placed, those Eb5’s are great really.
