How many male singers are born sopranos?

Answer 1

All human children are born with high voices, because their voice boxes are not developed enough to vocalize in the lower voice ranges.

Boys who sing before reaching puberty all sing in the higher ranges -- one is the soprano range -- and once their voices change, their voices fall into adult male voice ranges.

Notably, the Vienna Boys Choir is composed of males all born sopranos.

Answer 2

Male sopranos are quite rare, as the vocal range is typically associated with female singers. There have been a few instances of countertenors who sing in the soprano range, but they are typically categorized separately from traditional male singers.
