Voice Type

Light Lyric Soprano

Strengths/Achievements Consistent support up to A4/Bb4 Can occasionally bring support up to B4 Occasional resonance up to A4/Bb4 Supported sound down to Bb3/B3 Smooth legato Switches in head register fairly easily Weaknesses Airy chest voice Does not lift soft palate consistently Tight/strained sound above Bb4 Inconsistent head voice Voice lacks projection Occasionally produces a tight and tense sound in supported range Voice below A3/Bb3 can become quite airy Frequent throaty tonality in the mixed voice Registers Lower register: ChoA’s lower register is very comparable with the other vocalist around her skill level because she is only able to truly support her voice down to Bb3/B3 just like them. Below Bb3/B3 ChoA’s lower register loses much of the support, tone quality, and projection it once had, especially below A3.  Below A3 her voice loses almost all projection resulting in a weak and airy tone. Mixed register: ChoA’s mixed register is the most consistent part of her voice because she is almost always consistently supported up to A4/Bb4 and on rare occasions can bring small resonance up to A4/Bb4 as well. ChoA’s mix on the upper 4th octave and 5th octave notes is very strained, weak, shrill, and throaty due to a lack of muscle co-ordination. Upper register: ChoA’s upper register is fairly inconsistent because she has shown the ability to use a head voice, but often than not uses an airy falsetto. ChoA’s falsetto is fairly relaxed up to Eb5/E5 and has shown head voice up, albeit strained, up to A5. Agility

ChoA’s agility is fairly uncoordinated and underveloped. She lacks the muscle co-ordination to skillfully execute each individual pitch in a given run with accurate flow and precision.  This is most evident when she tries to do more complex runs with multiple notes like in the acoustic version of “Short Hair”, though each note is heard the flow and precision is lethargic even though the run is being done in a fairly slow speed. However, in the same performance, she does a much slower run with fewer notes with better flow and precision.

Overall analysis

ChoA made her debut with AoA in 2012 as their main vocalist in the main promotional unit as wel
