 "Soprano" refers mainly to women, but it can also be applied to men; "sopranist" is the term for a male countertenor able to sing in the soprano vocal range, while a castrato is the term for a castrated male singer, typical of the 16th, 17th, and 18th centuries, and a treble is a boy soprano who has not reached puberty yet and still able to sing in that range.The term "soprano" is also based on the Latin word "superius" which, like soprano, referred to the highest pitch vocal range of all human voice types.The word "superius" was especially used in choral and other multi-part vocal music between the 13th and 16th centuries.
