Evidence and review
Individual evidence review is pending. The displayed range is a reported reference span, not an independently verified physiological limit.
These are the approximate figures fans and music journalists commonly cite — the widest notes a singer has recorded, not the comfortable range they sing in every night, and not lab measurements. Treat them as a fun reference, not a target.
How IU uses that range
Almost nothing decorative gets added. Onsets land without scoop, the tone is small, bright and bell-like with very little air in it, and vibrato appears as a flicker at the end of a sustain, if at all. Above the E5 belt she thins into head voice rather than pushing. The climbing high run that closes Good Day stays connected the whole way up. Breathiness and a wider vibrato would cost the precision that defines the sound.

Small bell-clear soprano tone, exact pitch placement, and a light mix she keeps deliberately unforced.
