A castrato is a male singer who was castrated before puberty. The immediate effect on their voice was that they retained the high notes and range of their immature voice, but the operation also had a variety of other effects.
So castratos were a very tall and b had very large rib cages, giving them a vast amount of breath capacity. Castratos or, castrati, as it should technically be could wow audiences by holding notes for a superhuman amount of time as well as singing higher than a naturally matured male voice could.
But castrato singers first appeared in Europe in the midth century. Castrato singers appeared in Paris, Munich and they also made up the high-voice parts of the Sistine Chapel Choir. Kock, W.

Abstract Following the birth of modern opera in Italy in , the demand for soprano voices grew up and the prepuberal castration was carried out to preserve the young male voice into adult life.
Introduction Castration has been performed since centuries: from The Bible 1 to the ancient Rome and China, until the 19th century, orchiectomy was made for different reasons from punishment for prisoners of war, to castration of mentally deficient men for eugenics laws 2.

Singing with child-like vocal cords, their voices were also extremely flexible, and quite distinct from the equivalent adult female voice, with higher vocal ranges than the uncastrated adult male.
Although castration was illegal in some parts of Italy, thousands of poor families continued to send their sons down this uncomfortable route in search of stardom. Why was castration necessary? During the reign of the Catholic Church, females were not allowed to join the church choir, nor could they perform on stage, so this role was taken up by young boys instead.
However, as these boys reached puberty, the voice box, or larynx, drops and deepens about one octave. The longer and thicker vocal chords have a lower fundamental frequency, which no longer allows them to sing female songs. Hence the only way to preserve their beautiful voices into adulthood was to castrate them.
No matter how much the church opposed to the practice on the surface, the truth was they needed them for the choir, and they were afraid that banning the practice would affect church attendance. The second reason was that there was a market for castrati, especially amongst the rich people. Castrato singers were often hired by the royal courts or the upper class, and could earn a living that lets them to live lavishly and sometimes, that came with a great deal of power.
With an undisputed status on stage, a castrato could easily request the writers to alter the scores that did not please them, or if they felt the music could not demonstrate their talents to the fullest extent. Otherwise, they would simply take the music to their own composers for alterations.
Some of them were also so respected that they could assert great political influence. It was only until the nineteenth century that the trend for castrati began to fade.
The hormonal influence on voice persists throughout the lifespan of an individual and is different in males and females. The changes are important in certain professionals such as teachers and singers. The clinicians should have a high index of suspicion to identify an endocrine abnormality with an unexplained change in the voice. National Center for Biotechnology Information , U.
