Moon MyungJin’s Vocal Analysis

Vocal Range

Bb2 ~ G#5 (2 Octaves and 5 notes)

*Could possibly go higher/lower

Supported Range

E3 ~ A4/Bb4

Voice Type



  • Well developed middle register and mixed voice
  • Extremely good intonation
  • Very agile voice
  • Can sing outside of his supported range for long periods of time
  • Relaxed falsetto up to F5/F#5
  • Consistently resonant up to A4(possibly Bb4)

Points for Improvement

  • Doesn’t support his lower register below E3
  • Notes above A4/Bb4 are often pushed with a high larynx
  • Prefers to sing out of his supported range
  • Nasality can become present in his singing


  • Lower register: His weakest register, support is lost as high as Eb3. Has barely developed his chest voice muscles throughout the years, most of the tone is very light and thin.
  • Mixed register: Myungjin’s most developed register. Resonance is achieved up to A4/Bb4, notes above that are usually belted with a high larynx and some occasional nasality.
  • Upper register: An airy falsetto that lacks cord connection. Despite this, notes are generally relaxed up to F#5.


As his most focused genre is known to be soul and R&B music, it is safe to assume runs would be a big part of Moon Myungjin’s singing repertoire. Unlike many other younger vocalists though, he’s worked to develop the correct smooth connection of notes in his voice. As such, his vocal cords are able to move quite freely while still staying flexible and precise, hitting notes smoothly at the center of pitch and with the correct airflow. Even when strain is present, his vocal cords still don’t lose the smoothness. Being an R&B singer, Myungjin is no stranger to runs either fast, such as in “Standing In The Shade Of Trees“, or slow, such as in “Until The Morning Brightens.” He is able to sing speedy runs both in and out of his supported range, such as in “Not Just Sadness“and in his falsetto “I Believe I Can Fly.”

Overall analysis

Credited as “The R&B voice of Immortal Song,” Moon Myungjin debuted in 2001 as a soloist. He’s only released two full albums to date and has remained quite inactive since the release of his second album, but after coming back in 2011 to release a few songs, he quickly rose back to fame through his participation on Immortal Song 2. He became a lot more known through his participation in the special episode featuring Michael Bolton, which earned him more international awareness and fame.

One of his less apparent issues is his nonexistent lower register. Below E3, Myungjin simply fails to support his voice causing notes to be shallow and airy. This problem is barely noticeable though as Myungjin never really sings into his lower register. His style has had him close himself off to only using a limited area of his falsetto range as well as mostly staying in his mid-range and high belting range. So this over the years has caused his chest voice muscles to remain almost untouched, even as high as Eb3 he can sound quite light and airy. Even within his supported range, his chest voice is a lot lighter than many other tenors as his muscles are mostly head-dominant.

Myungjin’s most developed register is his mix. Even from low in his mix, he is able to produce a large resonance up to A4/Bb4. However from B4 Myungjin begins to push his larynx up when belting as well as not singing with a raised soft palate causing the notes to come out squeezed, thin, and nasal. Despite this, he is able to sing in his range for entire performances “How Am I Supposed To Live Without You.” Most notably his mixed voice seems to have a signature R&B sound and he tends to favor a more 90’s sound by slightly closing the back of his throat on purpose within his supported range, but then being able to open up very well and produce large resonance at will. This can be heard with the F#4’s in “기도.”

Myungjin’s second most developed range is his falsetto, which he has trained to be able to switch into at command. While airy, with hints of nasality, it is generally relaxed to about F#5. His falsetto shows good control and pitch. He transitions into it well, can use it stylistically to create more dynamics in his vocal performances, as well as using his overall control to jump up and down without losing his key center.

Moon Myungjin may have limited himself in terms of style over the years, but he knows himself as a vocalist. He is an artist first and foremost and knows his genre is R&B. He sticks to that genre like it’s his bible and is able to perform exceptionally well within that genre. As he knows himself as a vocalist and is known for his vocal skill, he has never failed to deliver performances. At his age, it isn’t likely for him to damage his voice even when singing outside his supported because of his level of skill and development. He stays generally within a fairly comfortable range as his mixed voice is developed well enough to handle many high and demanding ranges.


Myungjin is a master of changing songs to fit his style and convey emotions. Using his falsetto and upper belting to express pain and heartbreak as well as joy and love. He is an experienced vocalist and as an older and mature artist, he knows exactly who he is inside and out. This reflects very well in his vocal performances. He knows exactly the kind of sound he wants for his vocal performances and has complete control of how to use his own style. His stylistic approach may be limited to R&B, but within that genre he is able to create smooth, fresh and soulful versions of songs as long as he’s free to keep them within his comfort zone.

  1. I know supported range isn’t everything but his supported range is similar to Taemin’s but Taemin is AA-P while Myungjin is P. Correct me if I’m wrong about this but my understanding of this is Myungjin has more agile voice, a great sense of musicalilty, better support system(not sure) and very relaxed falsetto compared to Taemin’s.

    Anyway, thank you for the analysis.


    1. I mean musicality, consistency in openness and agility give him a much more well developed instrument and make him more skilled than Taemin, whose musicality and openness can limit him. The falsetto is sort of relevant, but it’s more to do with the rest.


  2. why is it older vocalist have full lyric voice type? both male and female. of course there are light lyrics too, but recently your analyses are full lyrics. is it just a coincident or a conspiracy from older vocalist? haha that is too overate. real thou, is kpop older vocalist prefer a full lyrics than light lyrics?


    1. It’s not to do with them being older, it’s just that they’re full lyrics. It is a pattern and actually looking at it, a lot of the upcoming tenors we have to analyze who are older than 30 are also full lyrics but some of them are light lyrics as well. I suppose because our voices only mature fully when we reach our late 20’s, we can find out our voice types then a lot more easily.


      1. considering the newer generation consist of light lyrics, i guess in the next 10 or more years there will be a lot older light lyrics than full lyrics. is it possible that this younger vocalists may not mature enough to be full lyrics? like kyuhyun now considered as light lyrics then when he got older his voice matured to be full lyrics? maybe it is just preference younger vocalist with light lyrics voice attract more interest? and older with full lyric voice is considered manly? hmmm i think i over thinking this matters too much haha


      2. Well it’s not about maturing enough, they either they’re full lyrics or they’re light lyrics. For an example Kim Bumsoo, Naul, Lee Hyuk and Lee Soo are examples of older tenors who are light lyrics despite being over 30.


  3. Oh i rmb him being mentioned that his analysis would be done since watching his vocal range video a few months ago. Great work! 😀


  4. No idea how I missed seeing this analysis when it was posted lol. This was another one I’d been looking forward to due to how many times I’ve seen him perform on Immortal Songs. Thank you!

    1. Hi. I have this feeling that He is a bit better than Kyungsoo in mixed register since Kyungsoo has jaw tension and consistency issues above A4 at times. Correct me if I’m wrong. On their agility, let’s wait the admins to reply. I have no idea too.


  5. I didn’t see you mention his head voice in the analysis.
    How about this: (1:26)

    Do you think it’s falsetto or head voice?
    Thank you.


  6. Omg I had no idea you posted this I am extremely extremely late but thank you for putting my video in. He recently had came out with an album and I think I found some more Bb4’s from him. I would like to make a best notes video of him, he is very underrated!

  7. This may be splitting hairs, but between 나얼 and 문명진, who would you say has better agility? Both are textbook R&B singers so I’m guessing there isn’t much difference?


      1. Very sorry for begging, would you please answer my short question which is at Naul’s vocal analysis?


      2. Im sorry dear but I don’t get notifications for his analysis and I can’t seem to find this comment in the recent comments. What is it?


      3. Oh I remember seeing that. I didn’t answer because I don’t think I could think of an example off of the top of my head.
