D3 ~ C#6 (2 octaves, 5 notes and 1 semitone)
F3/F#3 ~ B4/C5
F3/F#3 ~ E5 (With head voice)
- Able to keep decent tone production down to her lowest notes at times
- Having a better developed chest voice than most k-pop female vocalist
- Achieved resonance/open throat at times up to C5
- Healthier singing than most due to more use of head voice rather than a pushed mix
- Decent use of head voice and falsetto, able to keep good production mostly till E5
- Supports most of her mid range
- Able to use falsetto, head voice and a more mixed head voice for effect
- Pitch is almost 100% of the time on point, much more consistent than many other vocalists
- Larynx is unstable, tends to push with her throat more often than necessary
- Although able to lift her soft palate in low to mid-belts, tends to be nasal quite often
- Tends to squeeze a tense falsetto above E5
- Shallow support and control in her mix
- Underdeveloped mixed register with either too much chest or head, not balanced
- Although being able to at times support lower register, at other times it’s quiet and slightly too breathy
- Although having an extensive career, technique has not improved much if at all through her years
- Lower register: Able to produce supported and well connected notes in her lower chest, down to F3, occasionally D3’s, Eb3’s and E3’s are supported, at others very quiet and breathy. Although breathy, however, BoA is still able to produce more tone quality into her quieter lowest notes than most female vocalists with average lower registers.
- Mixed register: Able to use a heady mix or a chesty mix, but not a balanced mix. Either BoA’s mix is very pushed with a high larynx and a throaty sound, with too much weight carried up, or too bright and heady with a tight high larynx sound. Notes in the area from G4 ~ C5 tend to be opened most of the times with a lifted soft palate, but other times pushed and throaty, more like a yell than a real supported sound. Not able to mix correctly.
- Upper register: Very overused and tends to sing more with head than mix. She is able to transition well into head and without any problems in pitch, however above F5, tends to lose tone and become more of a falsetto with a very tight tense sound.
Although having a light voice, BoA’s voice is rather slow. She is able to do some easy vocal runs with decent pitch but they’re slightly tight and almost robotic.
BoA has a very different voice from most other female vocalists in K-pop. Although being an idol singer, she has a very extensive career which has lasted more than over a decade. Her voice is piercing, unique and very individual. She’s got a bright voice with a certain weightier quality to it due to the excessive chest she uses at times. BoA’s range is extensive down below allowing for more mid-rangey songs most of the time. She’s always been able to transition into ballads and pop, rather than being a vocalist, she’s more of an entertainer all around. Most of the time she uses a healthier technique by transitioning into head voice rather than pushing her mix/chest up too high, to allow for a smarter vocal approach.
BoA’s lower register tends to be very easily produced, with cord connection and a clear sound. It’s not too projected or resonant but it’s supported well enough down to F#3 and F3. At times she’s able to produce fuller notes below that range, but at others she’s rather quiet and breathy. BoA’s strength is her ability to stay in a lower range and quickly transition up to a higher range without much change in tone or larynx movement.
BoA’s mixed register is very weighty and chesty in its lower part from G4 ~ C5, where she at times will produced an opened more well projected sound with decent support, or at other times a more piercing shouty sound to her voice. She knows how to project her voice but her support is rather shallow and she tends to sing through her throat very often. Anything above C5 gets either too heady and her larynx shoots up, sounding rather strangled or she switches into head voice.
One of BoA’s strengths is the fact that most of her songs are in a higher range but she will use head voice instead of trying to push her mix. The few times where she did push her mix, it’s clear that she would bring either too much chest or too much head and make it sound rather uneven with a lot of tension and shallow support. Examples are her highest belts such as her C#5’s in “Spark” and more extremely her F5 in “Girls On Top”. On the other hand she’s still able to produced more opened notes below that, however so, her vibrato tends to close her throat up and make her sound tense and uneven. BoA’s vibrato is more uneven. BoA’s vibrato isn’t like other vocalists where it’s supported and naturally produced, but rather a throatier larynx vibrato which sounds forced and pushed at times.
BoA’s use of head voice is still her strong appeal for it’s done often and keeps her from trying to yell out notes she knows she can’t hit as well as she should. Her head voice stays pretty much consistent in pitch and production until F5 and above tends to have that same piercing shouty tight quality her upper belts have, which is due to the tension she adds to her vocal cords. Even if at times able to produce better G5’s and F#5’s, anything above is produced with a tense sound.
BoA’s two strongest points are her use of a healthier approach by head voice and her intonation. BoA’s intonation is almost always on point, she does not tend to go off key or be flat, her pitch is pretty much spot on, which compared to most other vocalists who lack proper support or vocal development is certainly a big strength and what keeps her from being the average strainer pitchy vocalist. What keeps her from being a certain above average vocalist is the tendency to at times be very throaty and her biggest issue, nasality. Throughout the years BoA developed a very nasal approach to her singing, which wasn’t as present in her early years. The moment she moved to Japan and started approaching her singing in a more “Japanese” way, her singing became more nasal and it’s something she’s only able to fix in some low-mid belts, but not in her lower range.
BoA’s vocal ability isn’t anything fancy or exaggerated, but she seems to be a vocalist who is aware of her level. She doesn’t try to do things she knows she can’t and that’s where her strength lies. Although she’s shown her weaknesses, she mostly uses her strengths which set her apart from other average female vocalists who try and do things they can’t, sounding unpleasant, strained and pitchy. BoA’s nasality is a very major issue she has not fixed in years and might not ever fix, but for her singing style and music, it fits. She is an all-around entertainer, songwriter, dancer and vocalist, who although not exceeding too much in those aspects, is very well balanced and sings in her own level and owns what she does.
BoA doesn’t tend to try and do things she doesn’t know how to. She’s a smart vocalist who uses her voice decently most of the time to produce good enough performances. She creatively tries and changes her songs around, but nothing dramatic or overly exaggerated, just enough to bring a slightly different flavor to her performances, but nothing musically challenging.
