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 Jessie J uses that range
Precision survives the volume here. Fast melismatic runs land dead center on pitch, and the belt stays compressed and bright right up to A5 rather than spreading wide. Onsets are clean and immediate with little scoop, and vibrato is fast, used mainly as an ending gesture. Dynamics move in steps, not swells. The imitation problem is spread: opening the vowel to get louder costs focus and pitch at the top.
