You might well wonder why on earth the Church, in particular, needed castrati even in the 16th century. The answer to this question is simple: women were banned from taking part in any sacred service, so choirs had to be exclusively male. Consequently, the feminine qualities of the castrato voice were hugely appealing, given that they mimicked a woman’s voice and tone without actually requiring the presence of a female in the choral ranks. Although the practice of castration did thankfully start to die away during the 18th century, castrati still formed a part of the Sistine Chapel choir as recently as 1903.
