Castrati
A castrato (Italian; : castrati) is a male singer who underwent castration before puberty in order to retain a singing human voice, voice equivalent to that of a soprano, mezzo-soprano, or contralto. The voice can also occur in one who, due to an endocrinology, endocrinological condition, never reaches sexual maturity. Castration before puberty (or in its early stages) prevents the larynx from being transformed by the Voice change, normal physiological events of puberty. As a result, the vocal range of prepubescence (shared by both sexes) is largely retained, and the voice develops into adulthood in a unique way. Prepubescent castration for this purpose diminished greatly in the late 18th century. Methods of castration used to terminate the onset of puberty varied. Methods involved using opium to medically induce a coma, then submerging the boy into an ice or milk bath where the procedure of either twisting the testicles until they atrophied, or complete removal via surgical cu ...

Castration
Castration is any action, surgery, surgical, chemical substance, chemical, or otherwise, by which a male loses use of the testicles: the male gonad. Surgical castration is bilateral orchiectomy (excision of both testicles), while chemical castration uses pharmaceutical drugs to deactivate the testes. Some forms of castration cause sterilization (medicine), sterilization (permanently preventing the castrated person or animal from reproduction, reproducing); it also greatly reduces the production of hormones, such as testosterone and estrogen. Surgical castration in animals is often called neutering. #Other animals, Castration of animals is intended to favor a desired development of the animal or of its habits, as an anaphrodisiac or to prevent overpopulation. The parallel of castration for female animals is spaying. Castration may also refer medically to oophorectomy in female humans and animals. The term ''castration'' may also be sometimes used to refer to emasculation where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eunuch
A eunuch ( , ) is a male who has been castration, castrated. Throughout history, castration often served a specific social function. The earliest records for intentional castration to produce eunuchs are from the Sumerian city of Lagash in the 2nd millennium BCE. Over the millennia since, they have performed a wide variety of functions in many different cultures: courtiers or equivalent Domestic worker, domestics, for espionage or clandestine operations, ''castrato'' singers, Concubinage, concubines or sexual partners, religious specialists, soldiers, royal guards, government officials, and guardians of women or harem servants. Eunuchs would usually be servants or Slavery, slaves who had been castrated to make them less threatening servants of a royal court where physical access to the ruler could wield great influence. Seemingly lowly domestic functions—such as making the ruler's bed, bathing him, cutting his hair, carrying him in his litter (vehicle), litter, or even rel ...

Testosterone
Testosterone is the primary male sex hormone and androgen in Male, males. In humans, testosterone plays a key role in the development of Male reproductive system, male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of androgenic hair, body hair. It is associated with increased aggression, sex drive, Dominance hierarchy, dominance, courtship display, and a wide range of behavioral characteristics. In addition, testosterone in both sexes is involved in health and well-being, where it has a significant effect on overall mood, cognition, social and sexual behavior, metabolism and energy output, the cardiovascular system, and in the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty, accumulation of adipose fat tissue within the body, anxiety and depression, sexual performance issues, and bone loss.

Voice Change
A voice change or voice mutation, sometimes referred to as a voice break or voice crack, commonly refers to the deepening of the voice of men as they reach puberty. Before puberty both sexes have roughly similar vocal pitches, but during puberty the male voice typically deepens an octave, while the female voice usually deepens only by a few tones. A similar effect is a "voice crack", during which a person's voice suddenly and unintentionally enters a higher register (usually falsetto) for a brief period of time. This may be caused by singing or talking at a pitch outside the person's natural vocal range, stress, fatigue, emotional tension, or the physical changes associated with puberty. An instance of a voice crack (when associated with puberty) lasts for only a moment and generally occurs less frequently as a person grows into maturity. Anatomical changes Most of the voice change begins around puberty. Adult pitch is reached 2–3 years later, but the voice does not stabi ...

New Grove Dictionary Of Opera
''The New Grove Dictionary of Opera'' is an encyclopedia of opera. It is the largest work on opera in English, and in its printed form, amounts to 5,448 pages in four volumes. The dictionary was first published in 1992 by Macmillan Reference, London, and edited by Stanley Sadie. Christina Bashford was the managing editor. While some entries were based on their equivalent entry in ''The New Grove Dictionary of Music and Musicians'', most were specially commissioned. The work contains contributions from over 1,300 scholars, with 11,000 articles in total, covering over 2,900 composers and 1800 operas. The operas discussed range from the earliest operas in 16th century Italy to the 1992 Philip Glass work '' The Voyage''. The final volume includes four appendices: an index of principal role names in 850 notable operas; an index of incipits of arias and ensembles (first line only, no musical examples); a list of contributors; and illustration acknowledgements.

Musico
The Italian term ''musico'' (: ''musici'') has a number of meanings: * Originally, the term referred to any trained, as opposed to amateur, musician. * In the 18th century, the polite term was used for the voice-type known today as castrato, which was considered a derogatory term at the time. The leading castrato in a company was referred to as a ''primo musico''. A diminutive form (''musichetto'') was also occasionally used. * In the 19th century, after the disappearance of castrati from opera, the term referred to a female singer, usually a contralto, who performed male leads in travesti.Warrack, John and West, Ewan (1992) ''op. cit.'' See also * Tenore contraltino The ''tenore contraltino'' is a specialized form of the tenor voice found in Italian opera around the beginning of the 19th century, mainly in the Rossini repertoire, which rapidly evolved into the modern "romantic" tenor.

Falsetto
Falsetto ( , ; Italian language, Italian diminutive of , "false") is the vocal register occupying the frequency range just above the modal voice register and overlapping with it by approximately one octave. It is produced by the vibration of the ligamentous edges of the vocal cords, in whole or in part. Commonly cited in the context of singing, falsetto, a characteristic of phonation by both sexes, is also one of four main spoken vocal registers recognized by speech pathology. The term ''falsetto'' is most often used in the context of singing to refer to a type of vocal phonation that enables the singer to sing notes beyond the vocal range of the normal, or modal, voice (M1). The typical tone of falsetto register, or M2, usually has a characteristic breathy and flute-like sound relatively free of overtones—which is more limited than its modal counterpart in both dynamic variation and tone quality. However, William Vennard points out that while most untrained people can sound co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vocal Cords
In humans, the vocal cords, also known as vocal folds, are folds of throat tissues that are key in creating sounds through Speech, vocalization. The length of the vocal cords affects the pitch of voice, similar to a violin string. Open when breathing and vibrating for speech or singing, the folds are controlled via the recurrent laryngeal nerve, recurrent laryngeal branch of the vagus nerve. They are composed of twin infoldings of mucous membrane stretched horizontally, from back to front, across the larynx. They vibration, vibrate, modulating the flow of air being expelled from the lungs during phonation. The 'true vocal cords' are distinguished from the 'false vocal folds', known as vestibular folds or ''ventricular folds'', which sit slightly superior to the more delicate true folds. These have a minimal role in normal phonation, but can produce deep sonorous tones, screams and growls. The length of the vocal fold at birth is approximately six to eight millimeters and grows t ...

Lung Volumes
Lung volumes and lung capacities are measures of the volume of air in the lungs at different phases of the respiratory cycle. The average total lung capacity of an adult human male is about 6 litres of air. Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath. The average human respiratory rate is 30–60 breaths per minute at birth, decreasing to 12–20 breaths per minute in adults. Factors affecting volumes Several factors affect lung volumes; some can be controlled, and some cannot be controlled. Lung volumes vary with different people as follows: A person who is born and lives at sea level will develop a slightly smaller lung capacity than a person who spends their life at a high altitude. This is because the partial pressure of oxygen is lower at higher altitude which, as a result means that oxygen less readily diffuses into the bloodstream. In response to higher altitude, the body's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limb (anatomy)
A limb (from Old English ''lim'', meaning "body part") is a jointed, muscled appendage of a tetrapod vertebrate animal used for weight-bearing, terrestrial locomotion and physical interaction with other objects. The distalmost portion of a limb is known as its extremity. The limbs' bony endoskeleton, known as the appendicular skeleton, is homologous among all tetrapods, who use their limbs for walking, running and jumping, swimming, climbing, grasping, touching and striking. All tetrapods have four limbs that are organized into two bilaterally symmetrical pairs, with one pair at each end of the torso, which phylogenetically correspond to the four paired fins ( pectoral and pelvic fins) of their fish ( sarcopterygian) ancestors. The cranial pair (i.e. closer to the head) of limbs are known as the forelimbs or ''front legs'', and the caudal pair (i.e. closer to the tail or coccyx) are the hindlimbs or ''back legs''. In animals with a more erect bipedal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epiphysis
An epiphysis (; : epiphyses) is one of the rounded ends or tips of a long bone that ossify from one or more secondary centers of ossification. Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, including the epiphyseal plate (growth plate). During formation of the secondary ossification center, vascular canals (epiphysial canals) stemming from the perichondrium invade the epiphysis, supplying nutrients to the developing secondary centers of ossification. At the joint, the epiphysis is covered with articular cartilage; below that covering is a zone similar to the epiphyseal plate, known as Wikt:subchondral, subchondral bone. The epiphysis is mostly found in mammals but it is also present in some lizards. However, the secondary center of ossification may have evolved multiple times, having been found in the Jurassic sphenodont ''Sapheosaurus'' as well as in the therapsid ''Niassodon, Niassodon mfumukasi.'' The epiphysis is filled wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
