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 Sinéad O'Connor uses that range
The range of dynamics inside a couple of bars is the technique. A phrase can start as a breathy near-whisper with the tone barely engaged, swell into a clear, straight mezzo, then fracture into hard rasp at the top of the crescendo. Cracks and breaks are placed, not accidental. Vibrato is scarce, arriving only at the end of a held note. Beginners start at full volume and leave themselves nowhere to go, which removes the entire shape.
