Extremes

The record holders

The widest spans, deepest floors and highest ceilings among famous voices — and why these particular numbers deserve the most scepticism.

Read these with the most caution

Record figures are the least reliable entries in any range collection, and for a structural reason: a number only becomes a record by being the most extreme claim in circulation, so the selection process actively favours whichever source exaggerated most. The rankings below are the figures fans and journalists repeat, not measurements.

The two specific things to distrust: a span this wide usually splits across registers a listener would not call the same voice — a six-octave figure typically runs from a growled subharmonic to a whistle — and the extreme note is often a single recorded moment, sometimes one produced with studio help, rather than anything the singer performs nightly.

The questions these tables get asked

Who has the biggest vocal range in the world?

No figure like this is lab-verified, so "in the world" claims are really "in circulation" claims. Among the 636 famous voices indexed here, the widest commonly cited range is Dimash Kudaibergen's C2–C8 — about 6.0 octaves. Spans that wide run from growled subharmonics to whistle register, not one continuous singing voice.

What is the highest note ever sung?

Claims vary and the extremes are one-off recorded moments rather than repeatable notes. The highest note cited in this collection is C8, for Dimash Kudaibergen — whistle register, a different mechanism from the voice doing the work an octave down.

What is the lowest note ever sung?

The lowest note cited in this collection is B0, for Geoff Castellucci. Notes this low carry almost no acoustic power, so cited floors depend on a microphone doing much of the work — the deeper the claim, the more that caveat applies.

Where you fit

None of these numbers is a target. The useful comparison is your own measured range against singers whose repertoire you actually want to sing — which the range test and the main chart do together.
