Gaetano Majorano was an Italian castrato and opera singer, who performed under the stage name Caffarelli. Like Farinelli, Caffarelli was a student of Nicola Porpora.

A castrato is a male singer who underwent castration before puberty in order to retain singing voice equivalent to that of a soprano, mezzo-soprano, or contralto. The voice can also occur in one who, due to an endocrinological condition, never reaches sexual maturity.
