URGENT PLEASWE READ THIS PART 1

For those unfamiliar with the term, a Castrato is a male soprano whose larynx was never transformed by puberty (i.e. lowered into Tenor or Bass range). Occasionally, this is the result of an endocrinological condition (as the Wikipedia tells me), but it was semi-common practice throughout the Catholic Middle Ages & Renaissance to castrate great boy singers to preserve their pristine upper ranges. (Countertenors are male altos with testicles who have perfected their falsetto, & were also commonly used in church music for centuries, & still sing modern & ancient music today. The last proper Italian operatic Castrato, Alessandro Moreschi, died in 1922. There are a few scratchy old recordings of him.)
