CHILD REARING PRACTICES.

INTRODUCTION

The way you raise your children can affect how successful they will be later in life.
There are various ways of child rearing practices they include:

1. Authoritarian parents: These are also referred to as autocratic or dictatorial parents. Parents in this category are insensitive of the children’s needs for expression. They are characteristically have  rare communication with their children. There are others who communicate but the communication is significantly negative. For instance, these parents who only talk to their children when they are reprimanding them. Most of these parents believe that children are there seen but not to be listened to. There communication is parent centered and does not give the child a chance express their own feelings.

                         Characteristics of children reared in this style
Extreme obedience. The fact that these children have been trained to follow the sacred rules, without questioning makes them obey to the extreme. These children follow directives from whoever is in authority without rising an eye brow, even when they do not quite agree or when they are not very sure. These children are likely taken advantage of by authority figures even if it is to their disadvantage.
They are likely to be timid. Due to harshness of their parents, these children fear that they may fail to perform to the expected level. They suffer from anxiety.
They have difficulties establishing relationships with peers. Authoritarian parents introduce their children into a hostile world. Children brought up in this style may not learn how to live in warm  relationship and may show some inferiority or be hostile when interacting with others. As a result they may not enjoy mutual relationships with others.
They could be aggressive and out of control. There are cases where children brought up in this style find the situation too harsh to cope with. They become hardened and rough. Such  children defy authority and can be very rough with others.
They are likely to be ignorant of many facts. This could be attributed by lack of explanation opportunities. These children are not likely to be innovative since they have to follow parent’s directives.
2.Authoritative parents
These are democratic parents. They allow dialogue between them and their children. Although they are willing to exercise control over their children they try to be understanding and rational. These parents reason with their children. They set realistic and consistent rules. They carefully explain the rules and allow some degree of independence and self-direction. They expect their children to make some substantive contribution in matters concerning their lives and activities. Parents appreciate their children’s participation.

                            Characteristics of children reared in this style
Independent. Since they are allowed to some degree of independence, these children trust their performance and freely work on their own.
Adventurous. The fact that these children are given some independence makes them become innovative. Their quest to know as a child is allowed to flourish. This leads them to get involved in finding out through experiments and adventure.
Altruism. Children learn a lot through role modeling. Through identification, children learn to behave like their parents. Since the parents have been role warm towards others. They learn to give a hand just like their parents have been concerned about their welfare. These children are likely to be popular among peers.
Self confidence. As their parents appreciate their contribution, these children learn that they have something to offer. They learn to acquire self respect and consequently believe in themselves.
Achievement oriented. Since these children are not pressured to perform, they set goals and pursue them. The cordial relationship that they enjoy with their parents propels them to gain mastery in their performance.

3. Permissive parents 
These parents allow their children to have their own way whatever it takes. They give them whatever they ask for. They are accepting and non-evaluating resources for their children. Parents using the  style hardly exert power or control over their children. They have little or no control over their children’s behavior.

                   Characteristics of children reared   in this style.
Aggressive. This is particularly common among children whose parents show no concern about aggressiveness at home. Such children are not likely to know that it is wrong to be aggressive.
Immaturity. The fact that the parents have not allowed these children to face challenges and solve them makes them remain childish especially in matters regarding to social interaction in peer relationships.
Avoid responsibility. Since their parents have not accustomed them to playing distinct roles at home, these children are  not likely to take responsibility. For example they avoid duties at school.
Lack self confidence. As they interact with others, they are ridiculed for their crude behavior. They feel embarrassed by their own behavior and this leads to loss of self confidence.
Anxiety. Since they are uncertain about what their behavior and the consequences, these children are likely to be habitually anxious.

4. Neglecting parents
These are the most un-involved parents. They are selfish and show little interest if any in their children’s activities. They are often unaware of their children’s whereabouts or their welfare. These parents are mainly concerned about their own immediate needs and convenient. They fail to teach their children attributes necessary for an effective social life.

                        Characteristics of children reared in this style.
Showing disturbance in relationships with peers and adults. Since the child lacked warm relationship in the formative years, he/she may not feel comfortable in relating with others.
Presence of anti-social behavior. Children are subjected to fending for themselves and lack guidance. They may thus be involved in vices such as truancy at school or other forms of juvenile delinquency.
They are likely to be moody and disobedient. Due to emotional imbalances that are associated with neglect and insecurity, these children may not afford to be consistent in their interaction with others.
Lack of sense of direction. These children have received little or no guidance at all and may be engaged in trial and error practices.
Poor performance at school. Factors such as truancy, absenteeism and involvement in vices divert the energy that could be directed to academics. Children who feel neglected may day-dream in class hence fail to learn in class.

                                          Tips for parenting.
1. Your children are not to be considered as your mere substitutes of the materialization of lost dreams.
2. Your children are not mere reservoirs for downloading your frustrations in your past life.
3. Your children too are unique individuals with distinctive identity and personality.
4. Do not expect your children to reciprocate the same love and protection you have extended to them.
5. Wether or not your children reciprocate your care and love, you have no choice but to rear them decently and justifiably as much as you can.
6. Expose them gradually to challenges and tests so that they will be brave themselves.
7. Stuff them with detached and disinterested love and care rather than excessive subjective affection.
8. Provide your children with comforts but never try to gratify their want for luxuries.

                                    Principles of child rearing.
1. Pay careful attention to your marriage or yourself, if you are single parent. Your marriage if it is strong and satisfying, will give your children more security than any amount of attention. If you are single, your sense of self respect and fulfillment as a person can act as the same sort of anchor for children.
2. Expect your children to obey you. Don’t apologize for decisions you make. Children need strong, confident parents upon whom they count to be authoritative, decisive and trust worthy. You are in charge of the family. As long as children live in your house, they don’t have the right to make decisions for themselves, you allow them the privilege of making decisions and you always have the option of revoking that privilege if it is abused.
3. Don’t be intimidated by the experts. Use suggestions and ideas that make sense to you and your family, but remember that all parent make mistakes now and then, and children are not permanently scarred by them. Raise your children your way and enjoy the results.
4. Turn off television. Preschool children need to play so that they can develop basic competency skills, learned by touching and exploring their environment. Nothing happens when a child sits passively in front of a television screen. Children should not be allowed to watch television until they have learned to read and enjoy books usually between class three and four.
5. Say no, and say it often. If the response is a tantrum, so be it Exposure to frustrations prepare children for the realities of adulthood and gives them tolerance a key ingredient to every successful story. Your obligation is not to make your children happy but to give them the skills to pursue happiness on their own. Don’t say arbitrarily, rules must be consistent and the reasons for them explained.

Causes of amnesia



Depression
Memory loss and an inability to focus may not seem like obvious symptoms of depression, but they are more connected than most people realize Research has suggested that processing speed or the ability to take in information quickly and efficiently is impaired in individuals who are depressed. Many areas of the brain are involved with the creation and retrieval of memories. Irregularities in any of these areas, including those that create depression symptoms, can affect how one process memories and also influence your ability to concentration.

At first, depression-based memory loss and difficulty focusing may just be mildly annoying, but these types of cognitive defects can become quite serious over time and result in a diminished level of functioning in many capacities. For example, People with depression often feel like they can’t focus when giving or receiving direction, which can result in misunderstandings at home, work, or school. This explains why Jay lost his direction when going home after work. Relationships may suffer if people begin to perceive your distraction as a lack of consideration for what they’re trying to tell you. 

Jay’s friends felt disappointed when he could not remember the good moments of their friendship. Individual’s with amnesia find that they can’t focus on a task if other things are taking place around them, distracting them from their intended job and leaving it incomplete or below expectations. Also, comprehending what they are reading may become difficult, resulting in missed information from written instructions or a lack of enjoyment when reading for pleasure. Their ability to remember specific details may be hindered due to lack of concentration when given new information. This explains Jay’s poor performance in school after the presence of the disorder. People with amnesia are instructed not to drive. This is because driving can become dangerous if their train of thought strays and you find you can’t focus on the road.


Anxiety
Memory loss affects different individuals in different ways. It tends to be more severe in those with sever anxiety. The main cause of memory loss is a hormone known as cortisol. It's the hormone released during stress, which is why those with severe anxiety and ultimately severe stress are more at risk for developing memory loss problems. Numerous studies have confirmed that cortisol contributes to memory loss, especially short term memory loss, because it is a toxin to the cells of the brain. The longer one deals with anxiety, the more cortisol one will have in his or her system, and that means that he or she is more likely to continue suffering from memory loss in the future.

Other causes of amnesia include:
 Underactive thyroid- this means one thyroid gland which is found in the neck does not produce enough hormones. Individuals with lower activities of the thyroid gland are at risk of memory loss which is a sign of amnesia.
Stressful event- this type of amnesia is known as psychogenic amnesia. It is whereby the patient blocks out a part of his or her memory of an unpleasant event in the past. This makes them unable to remember important information. The loss of jay’s grandfather triggered the onset of amnesia and the partial paralysis. Psychological stress during childhood may lead to childhood amnesia. This leads to Inability to remember events during that period of life.

 Medications- certain types of medication, such as sedatives and some treatments for Parkinson’s disease  may lead to memory loss over time.

Symptoms of amnesia
Loss of explicit memory - The typical amnesic patient is unable to recall recent information like what they ate for lunch or a newly heard telephone number. These are called explicit memory as they are memories for facts and events that are capable of being consciously remembered. Patient or sufferer of loss of explicit memory can often declare the loss as this is in his or her knowledge. One evening Jay lost his way home from the shop across the street and was nearly knocked down by an oncoming vehicle if it were not their neighbor who held his hand and took him home

Loss of implicit memory – Implicit memory refers to retention of the event or material information but incapability to recall it through conscious eort. In many cases the patient does not even have the knowledge that he or she has this information. Jay denied knowing of any existence of their long time car of which he had the duplicate keys. He also, could not trace misplaced items in the house.

Anterograde amnesia – this means the patient forgets all events that have happened after a particular traumatic event. This is seen in acute or sudden onset amnesia like after a head injury, stroke or seizure. These patients do not tend to forget their childhood, events and skills prior to the accident. They however have trouble remembering day-to-day events.
 
Retrograde amnesia refers to an inability to remember information that was acquired before the traumatic event or disease. Typically there is very poor recall of events that occurred in the near past of the brain damage. He could not remember his lower grade classmates including Ian who visited him at home frequently. His cousin whom they spend most of their childhood together found it hard to remind his their best moments back then of which jay found strange and unfamiliar.


Human Resources Management Tasks



Introduction
Human management tasks are several and they are integral in the running of any business. For a business to realize its objectives, the human resource management must ensure that they bring together the human resources and the capital to have the desired out come. (Amello, 2014)Human resource management tasks can be looked into in terms of strategic human resource management, job design and satisfaction and human resource management compliance e with the law. In this paper I will look at these elements with reference to the young women Christian association of New York City which I am familiar with.

1.      strategic human resource management
This is the practice of linking the strategic plan of an organization with the employees in that organization. It involves ensuring that employees work towards the mission, goals and objectives of the organization. This he is important in that it sets the ground for work and gives a rationale for any activity performed. It would be difficult for employees to work without a goal or a target. (2010) in the New York City young women Christian association, the employees are first made aware of the organizations goals at the beginning of each period and they are able to bench mark from these. This is made possible by the well allocated roles that inform employees what is expected of them. The various posts have their work responsibilities well drawn out, and they are fully informed of the programs goals. This has seen to them working towards the elimination of racism directed towards women making it one of the most successful organizations.

2.      Human resource planning
Human resource planning is the practice of ensuring that an organization has the right number of employees with the right skills so that they can make it possible to realize the goals set. It also includes forecasting changes in the demand for skills and takes care of this.  It is important in identifying the number of employees with the right skills as well as identifying the future needs of the organization.(Kleynhans and Aswegen,2006)  The new York YWCA human resource management has effected this practice by hiring competent individuals who are rightly placed to tackle discrimination against women. To add on to this team, they always have a room for contractual hiring of professional whenever there is a task at hand which requires special skills. However some of those who are hired cannot be retained in the organization since their skills are not always in need. It is more economical to hire them on contractual basis.

3.      human resource information management systems
This involves the management of software or a data base that keeps data about the employees which can be retrieved at any time when needed. This includes a bank of their details and their competencies and the various tasks that they can perform. It helps in duty allocation without having to assess the employees again. (Deb, 2009) the New York YWCA maintains a human resource management information system with the details of all the employees and their credentials which help during appraisals and special task allocation. A good example is the information found on their website with the names of the members of staff, the positions they hold, their educational background among other information.
4.      Human resource management and the law
Human resource management should be fully compliant with the local, regional and international laws governing employment. These laws are meant to protect the employer and the employees. The observances of these laws help an organization to maintain best practices and protect their employee from exploitation. These laws are found in the constitution, international labor organization provisions and other regional acts. The YWCA of New York City is fully compliant with this by providing the employees with the correct working environment which is not detrimental to their health. The organization is fully compliant with the law and their operations are open to the scrutiny of the applicable law. (YWCA of New York, 2014)
5.      Job analysis design and quality of life
Job analysis is a close scrutiny of what people do, how they do it and the results they achieve in doing so. (Gilley and Eggland...). This helps in coming up with proper job descriptions that befit the employees work competence and hence improve the output. Job design refers to how the work is carried out and the environment in which it is carried. It also refers to the comfort ability of the job with reference to employee. A god job analysis and design result to good quality life of the employee and more retention in the job. In New York YWCA, the management has put up a clear explanation of what each position is responsible and the employees in these posts are bound to follow that. The organizations offers flexible work schedules to the employees with a good vacations which duration increases as ones number of years in the organization increases. The employees attend free trainings held by the organization all year round and they receive free services from the organizations facilities. This has led to a more fulfilling career life in the organization and it is one of the organizations with high employee retention levels.  Job analysis, design and quality of work are three intertwined aspects and they are very interdependent.

Communicable diseases



The recent figures produced by The World Health Organization (WHO) demonstrate that, there has been a raging increase of transmissible diseases across the world. This has mainly been attributed to two key factors, which comprise; galloping population increase and the changes in inoculation practices around the world boosting the spread of such diseases like measles, avian influenza, and SARS. In the latest times, of the most common infectious diseases, Measles has been on top of the list in terms of prevalence, incidence rates, and severity.

According to Griffin and Oldstone (2008), Measles is a very deadly disease and spreads over a large interactive population at a fast rate through contact. While most people may have little idea on Measles as a contagious infection, it is crucial to note that the disease is very transferable, unbridled, and fatal if not controlled within the predetermined period.

The highest case of outburst of Measles was reported back between 1985 and1991. Statistics reveal that during this period, more than 790 cases surfaced. This number comprised 26 cases documented from four states of the US including California, Colorado, Utah and California. The cases were reported of people with running nose, cough, red eyes and sore throat. These are typical signs of measles. More than half, of the 26 were children infested with the virus and not vaccinated

 It farther shows that the most affected population comprised of the health workers as supported by the data. Of the total cases reported, workers in the health sector accounted for 1.1% and were mainly adults.  It is interesting to note that 29% health workers were nurses, 15% were physicians 11% other occupational health workers mainly working in the laboratory and radiological technicians. However, there was a decline in the Measles incidence rates as of 1993 and late 1991 which was a reprieve to the world a little bit. During this period in time, there were as few as less than 40 cases reported. This number comprised of 1.8% health workers mainly the laboratory specialists, clinical officers and nursing professionals.

Throughout 1988 to1990, California had its foulest measles endemic in more than a decade, with 16,400 recounted cases, more than 3,390 hospitalized, and 75 deaths. The disease aligned in low-income Hispanic populations in central and southern California. The key cause of the endemic was stumpy inoculation levels among preschool-aged kids and young grown-ups. The rates of complications, hospitalization, and death were amazingly lofty. The usual account of measles virus is reflected in the epidemiology of the sickness.

           Mathematical approach has been employed to explain the stretch and periodicity of the epidemics by various scholars. In this advance, the population size and proceeding immunological incident are key factors are considered. Measles tend to die out in population of 250,000 and less until it is re-introduced from outside that is when the virus takes its root again in the population.

The measles virus multiplies extensively at the mucous surface, which perhaps reveals whether the victim is predisposed or resistant. At this phase of the infection, the symptoms and signs of incursion are known to occur. Serological research by Black and Rosen (2001) reveal that there is a consistent drop in the mean titers of the antibody to the virus over the years. It is rare to witness second attacks by the virus and the systemic invasion of the virus is likely not to reappear.

The virus causing measles is mainly acquired from the environment and from other person. The route of transmission is critical in helping us understand whether it leads to infection or not and most importantly help us in the attempts to protect ourselves from the infection.

Measles can be transmitted through two main routes that include direct and indirect transmission. In direct transmissions, it occurs when two people are in contact i.e. physical contact in the case of sexual intercourse, kissing, nose, tears and biting. On other hand, indirect transmission involves when there is an intermediary organism or object playing a role, for example, bacteria in the fatal stage may be spread on clothes to cause diarrhea. Below is a graphic representation of the outbreak of measles’ by Month and WHO Regions,2008-2013.



Measles epidemic has serious impact on the community, which is centrally hinged on the financial crisis mainly in developing countries.  A survey conducted by outbreak response immunization(ORI) in the rural Peru community proceeding the outbreak of measles indicate that, more than 150 residents of the local community of about 553 developed clinical cases of measles. This represents about 20% of the local community was affected.  

The population mainly constituted the young energetic individuals that contribute to the productivity of the country hence the economy. Moreover, measles medication is finance intensive. These factors combined have a big impact on economic growth and development of the country. The other effect of measles is death, which in turn reduces the productive portion of the population in the community.

Severe Acute Respiratory Syndrome is a contagious disease that is spread through direct contact with the infected person. The virus is transmitted through respiratory fluids that mainly include mucous. After confirmation of SARS, cases are reported to the regional disease surveillance office. The samples are sent to the medical research institute for analysis after which the results are taken to the National Center for Disease control and prevention (CDC) for appropriate control measures to be taken.

The quality of air has big influence on patients with respiratory diseases. It is therefore a good clinical practice to adopt certain measures to ensure safety and reduced predisposition of such patients. Poor air quality is associated with concentration of ozone gas. In a bid to protect patients with respiratory diseases, measures should be taken to curb ozone gas concentration. The modifications may include advising patients to stay within on ozone-alert time and limit time out-of-doors. Limit vigorous open-air events to early morning or evening, when air value is improved and retain windows locked. Cogitate using an aversion facemasks since wearing a mask confines exposure to allergens.

Classical music



THE CLASSICAL MUSIC (1775-1825)
The Baroque period culminated in the masterpieces of J.S. Bach and G.F. Handel. In the middle of the eighteenth century, contemporaneous with the mature years of Bach and Handel, a new musical style developed that is known as Rococo or pre-classical style. This style is most evident in keyboard and orchestral music, but it is mentioned here because it represented a transition from the Baroque to the Classical era, occurring between 1725 and 1770.
In the world of painting, Rococo style is characterized by delicate colors, many decorative details, and a graceful and intimate mood. Similarly, music in the Rococo style is homophonic and light in texture, melodic, and elaborately ornamented. In France, the term for this was style galant (gallant or elegant style) and in Germany empfindsamer stil (sensitive style). François Couperin (1668-1733), in France, and two of the sons of J. S. Bach, C. P. E. Bach (1714-1788) and Johann Christian Bach (1735-1782), in Germany, were important composers of music in the Rococo style.
In the second half of the eighteenth century, a reaction against Rococo style occurred. There were objections to its lack of depth and to the use of decoration and ornamentation for their own sake. This led to the development of Classical style.
The Classical period itself lasted from approximately 1775 to 1825. The name classical is applied to the period because in art and literature, there was keen interest in, admiration for, and emulation of the classical artistic and literary heritage of Greece and Rome.
Intellectually, this era has also been labeled the Age of Enlightenment. Philosophers such as Rousseau, Voltaire, and Montesquieu wrote of the value of the common person and the power of human reasoning in overcoming the problems of the world. This revolution in thinking inevitably led to conflict between the old order and new ideas. The French and American revolutions in the last quarter of the eighteenth century were stimulated by this new attitude.
The musical scene in the classical period reflected the changes occurring in the society in which the music was being written. This was the first era in music history in which public concerts became an important part of the musical scene. Music was still being composed for the church and the court, but the advent of public concerts reflected the new view that music should be written for the enjoyment and entertainment of the common person.
Unlike the Renaissance or Baroque eras, which included many important composers and trends, the choral music of the classical era was dominated by three composers: Franz Joseph Haydn (1732-1809), Wolfgang Amadeus Mozart (1756-1791), and Ludwig van Beethoven (1770-1827). For the first time, during the Classical period most of the important stylistic advances that occurred can be observed most clearly in the instrumental forms: the symphony, concerto, sonata, and in instrumental chamber music (e.g., the Beethoven string quartets). Church music tended to be more conservative than secular compositions, which also helps to explain why stylistic innovations were seen most clearly in instrumental music but were less prevalent in the choral music of the period.
Choral and instrumental forms overlapped during the Classical period to an unprecedented degree. Forms developed in the instrumental area were appropriated and used to good effect in choral music. Sonata allegro form, for example, often found in sonata or symphony movements, is also used in sections of classical masses. Beethoven included choral sections in two instrumental works, his Choral Fantasia and the Ninth Symphony.
This period in music history is sometimes referred to as "the Viennese Classic period," and it was centered in Vienna. Beethoven, Haydn, and Mozart, though none was a native Viennese, all worked in Vienna for significant periods in their careers. Although Vienna was the focal point for musical activity of the period, classical music is not parochial but universal in spirit and in style.


Important Forms
Important forms of choral music during the classical period included the following:
Mass. The mass continued to be an important form for each of the three primary Classical composers. During the Classical period, masses involved orchestra, soloists, and choir in a fully integrated work, utilizing organizational principles derived from instrumental forms.

Missa Brevis. This concise treatment of the mass text may consist of strictly delimited development, simultaneous setting of several lines of text, or the omission of certain sections of the mass.
Missa Solemnis. When choral musicians refer to the Missa Solemnis they are usually speaking of Beethoven's Mass in D Major, a milestone in the development of choral music. In a broader sense, however, the term refers to a more elaborate and extended musical treatment of the mass text than that employed in the Missa Brevis.

Oratorio. The Baroque oratorio tradition, begun by Carissimi and culminating in the works of Handel, was continued in the Classical period primarily by Haydn, who wrote two oratorios, The Creation and The Seasons, which have remained an important part of the choral repertoire.
Requiem. Although many musical settings of the Requiem were composed during the Renaissance and Baroque periods, the Classical period produced a setting by Mozart (completed by a student following Mozart's death) that has become a staple of the choral repertoire and two settings by Cherubini that are also often performed.

Vespers. Mozart wrote two settings of this service each of which includes psalms and the Magnificat, written for choir, quartet of soloists, and orchestra.
Choral Symphony. A symphony which includes sections written for choir and orchestra. The earliest and probably best known example of this is Beethoven's Ninth Symphony, incorporating choir and soloists in the fourth movement.

Composers
Haydn. Franz Joseph Haydn was born in the Rohrau, Austria, in 1732. At age eight he was accepted as a choirboy at St. Stephen's Cathedral in Vienna. When he left St. Stephen's in 1749, he became an assistant to Nicola Porpora. In 1759, he worked briefly as musical director for Count Morzin, and in 1761 was employed as assistant music director and then music director for the Esterhazy family, residing at their estate. He remained with the Esterhazys for nearly thirty years, until 1790.

During the last decade of the eighteenth century, Haydn made two trips to London. He had been hired by Johann Peter Salomon to compose and conduct six symphonies for his first trip (1791-1792) and six for his second (1794-1795). Haydn's London appearances were highly successful.
Upon his return to Vienna in 1795, Haydn composed some of his most significant choral music. The six masses from this period, composed for Prince Nicholas Esterhazy (the son of Haydn's earlier employer), and his two oratorios, The Creation and The Seasons, are his most significant choral works. Haydn's total choral output included twelve masses, three oratorios, a passion, two Te Deums, a Stabat Mater, and a few other smaller works.

In his later years, Haydn was a celebrity whose works were widely recognized and appreciated, in contrast to the decades spent in the relative isolation of the Esterhazy estate. He died in 1809 in Vienna.
Mozart. Wolfgang Amadeus Mozart was born in Salzburg, Austria, in 1756. At the age of six, he could play the harpsichord and violin, compose, and performed in Munich and Vienna. Between the ages of six and fifteen, Mozart was taken on tours of Europe and England, organized by his father, Leopold Mozart, a Salzburg court composer. Although he was away from home more than half of the time, he produced a steady stream of compositions during this period.

In 1781, Mozart left Salzburg and moved to Vienna, teaching, concertizing, traveling, and continuing to compose constantly. In contrast to Haydn, who worked in the isolation and relative obscurity of the Esterhazy estate for many years and then became an international celebrity in his sixties, Mozart was thrust into international prominence as a child and encountered decreasing public acceptance of his music when he was an adult.

By 1791, Mozart's health was failing. He received a commission that resulted in the composition of The Magic Flute. He was also visited by a representative of a Count Walsegg, who commissioned a requiem. Mozart may have believed he was writing a requiem for himself. He died before completing the work, and it was finished by a pupil of Mozart's named Sussmayer, working from Mozart's sketches of the unfinished portion.

Mozart's choral output includes eighteen masses, the Requiem, two Vespers settings, and a variety of shorter choral pieces. Beethoven. Ludwig van Beethoven was born in Bonn, Germany, in 1770. He came to Vienna in 1792, where he studied with Haydn and Albrechtsberger. His first public performances in Vienna as a pianist and composer came in 1795.

Beethoven protested against the patronage system that bound musicians to the service of an employer. 
Increasingly deaf, Beethoven eventually was forced to retire from public performance and to concentrate on composition. Unlike Mozart, who seemed to conceive of music in final form and who simply wrote down his conceptions, Beethoven's sketchbooks provide a record of his agonizing struggle to arrive at a composition he felt was satisfactory.

Beethoven was primarily a composer of instrumental music, and it is in his symphonies, piano music, and string quartets that the transition from Classic to Romantic style is most clearly discernible. Nevertheless, his choral music is an important part of the repertoire, and his Mass in D Major, the Missa Solemnis, is one of the monuments of Western musical tradition. Beethoven's choral output included two masses, an oratorio, two symphonic works with large choral sections and a few smaller pieces.

Classical Style
Music from the Classical period is distinctive in style from what preceded and followed it. Some of the questions related to performance practice in Renaissance and Baroque music are less complex because at this point in Music history we have much clearer and more explicit indications from the composer concerning the tempo, dynamics, and expressive qualities of the Music under consideration.
Moreover, there have been public performances of this repertoire from the time of its composition to the present. This is both a help and a hindrance in light of the fact that through the last two centuries, certain Romantic conventions have become an accepted part of the performance of this music, and they are not always appropriate to authentic Classical style (this same Problem of inappropriate performance conventions added during the Romantic period exists with Baroque repertoire and, to a lesser extent, music from the Renaissance).

Classical choral music tends to be more homophonic and lighter in texture than that of the Baroque. This lightness needs to pervade the choral lines. There is still rhythmic energy and drive, but without the weightiness of Baroque music.

The lighter quality of Classical music also is derived from its slower harmonic movement. Baroque music, with its emphasis on vertical structure and use of figured bass and basso continuo, is characterized by frequent harmonic changes, sometimes on every beat. Classical music changes chords much less frequently, giving it a more graceful sweep and lightness of phrasing than that created by the pulsating feel of a harpsichordist realizing a Baroque figured bass part, supporting the choral singing with rapidly changing embellished chords. During the Classic period, the keyboard player was no longer typically the composer/ conductor, but instead was simply one of the players in the orchestra. The keyboard part should be much less obtrusive and less highly decorated than that of a Baroque work.

The choral music of the Classic period is generally conservative, and therefore often contains sections of free counterpoint, fugue, and use of continuo, reminiscent of the Baroque. This is particularly true in the music written in the early part of the period.
The Classical era was an era of formality. The music was characterized by careful attention to form and by elegance and restraint. The formal structure was based on the use of thematic development and harmonic structure.

The music of the Classical era is characterized by objectivity. While emotion is an important aspect of all music, in the Classical period, emotions were carefully controlled. This control is evident in the use of dynamics and expressive differences within sections or movements of a composition. The Baroque notion of terraced dynamics, coupled with the expression of a single emotion in a given section of a composition, was replaced by the classical trait of varying the emotional content of a given movement, section, or even a measure of a piece. Dynamically speaking, this was accomplished through the use of crescendo and decrescendo.

Definition as a formal model
A sonata-allegro movement is divided into sections. Each section is felt to perform specific functions in the musical argument. It may begin with an introduction, which is, in general, slower than the main movement. In terms of structure, introductions are an upbeat before the main musical argument.

The first required section is the exposition. The exposition presents the primary thematic material for the movement: one or two themes or theme groups, often in contrasting styles and in opposing keys, connected by a modulating transition. The exposition typically concludes with a closing theme, a codetta, or both.
The exposition is followed by the development where the harmonic and textural possibilities of the thematic material are explored.

The development then re-transitions back to the recapitulation where the thematic material returns in the tonic key, and for the recapitulation to complete the musical argument, material that has not been stated in the tonic key is "resolved" by being played, in whole or in part, in the tonic.
The movement may conclude with a coda, beyond the final cadence of the recapitulation.
The term 'sonata form' is controversial and has been called misleading by scholars and composers almost from its inception. Its originators implied that there was a set template to which Classical and Romantic composers aspired, or should aspire.

However, sonata form is presently viewed as a model for musical analysis, rather than compositional practice. Although the descriptions on this page could be considered an adequate analysis of many first-movement structures, there are enough variations that theorists such as Charles Rosen have felt them to warrant the plural in 'Sonata forms.'[7]
These variations include, but are not limited to:
Through the Romantic period, formal distortions and variations become so widespread (Mahler, Elgar and Sibelius among others are cited and studied by James Hepokoski) that 'sonata form' as it is outlined here is not adequate to describe the complex musical structures that it is often applied to.
In the context of the many late-Baroque extended binary forms that bear similarities to sonata form, sonata form can be distinguished by the following three characteristics:[6]
  • a separate development section including a retransition
  • the simultaneous return of the first subject group and the tonic
  • a full (or close to full) recapitulation of the second subject group
Outline of sonata form
The standard description of the sonata form is:

Introduction
The Introduction section is optional, or may be reduced to a minimum. If it is extended, it is, in general, slower than the main section, and frequently focuses on the dominant key. It may or may not contain material that is later stated in the exposition. The introduction increases the weight of the movement, and also permits the composer to begin the exposition with a theme that would be too light to start on its own, as in Haydn's Symphony No. 103 ("The Drumroll") and Beethoven's Quintet for Piano and Winds Op. 16. The introduction usually is not included in the exposition repeat.

On occasion, the material of introduction reappears in its original tempo later in the movement. Often, this occurs as late as the coda, as in Mozart's String Quintet in D major K. 593, Haydn's "Drumroll" Symphony, or Beethoven's Piano Sonata No. 8 ("Pathétique").

Exposition
The primary thematic material for the movement is presented in the Exposition. This section can be further divided into several sections. The same section in most sonata form movements has prominent harmonic and thematic parallelisms (although in some works from the 19th century and onward, some of these parallelisms are subject to considerable exceptions), which include:


First theme (G major) and transition (to D major) from Haydn's Keyboard Sonata, Hob. XVI: G1, I, mm. 1–12. First subject group, P (Prime) – this consists of one or more themes, all of them in the tonic key. Although some pieces are written differently, most follow this form.

Start of second subject (D major) of Haydn's Sonata in G Major, Hob. XVI: G1, I, mm. 13–16.
  • Transition, T – in this section the composer modulates from the key of the first subject to the key of the second. If the first group is in a major key, the second group will usually be in the dominant key. However, if the first group is in minor key, the second group will usually be the relative major.
End of second subject and Codetta (D major) of Haydn's Sonata in G Major, Hob. XVI: G1, I, mm. 17–28.
Second subject group, S – one or more themes in a different key from the first group. The material of the second group is often different in rhythm or mood from that of the first group (frequently, it is more lyrical).
  • Codetta, K – the purpose of this is to bring the exposition section to a close with a perfect cadence in the same key as the second group. It is not always used, and some works end the exposition on the second subject group. The exposition is commonly repeated, particularly in classical works, and more likely in solo or chamber works than for concerti. Often, though not always, the last measure or measures of the exposition are slightly different between the repeats, one to point back to the tonic, where the exposition began, and the second to point towards the development.
Development

Development Haydn's Sonata in G Major, Hob. XVI: G1, I, mm. 29–53 .
In general, the development starts in the same key as the exposition ended, and may move through many different keys during its course. It will usually consist of one or more themes from the exposition altered and on occasion juxtaposed and may include new material or themes – though exactly what is acceptable practice is a point of contention. Alterations include taking material through distant keys, breaking down of themes and sequencing of motifs, and so forth.
The development varies greatly in length from piece to piece and from time period to time period, sometimes being relatively short compared to the exposition (e.g., the first movement of Eine kleine Nachtmusik, K 525/i by Mozart) and in other cases quite long and detailed (e.g., the first movement of the "Eroica" Symphony by Beethoven). Developments in the classical era are typically shorter due to how much composers of that era valued symmetry, unlike the more expressive romantic era in which development sections gain a much greater importance. However, it almost always shows a greater degree of tonal, harmonic, and rhythmic instability than the other sections. In a few cases, usually in late Classical and early Romantic concertos, the development section consists of or ends with another exposition, often in the relative minor of the tonic key.
At the end, the music will usually return to the tonic key in preparation of the recapitulation. (On occasion it will actually return to the sub-dominant key and then proceed with the same transition as in the exposition). The transition from the development to the recapitulation is a crucial moment in the work.

Retransition Haydn's Sonata in G Major, Hob. XVI: G1, I, mm. 54
The last part of the development section is called the retransition: It prepares for the return of the first subject group in the tonic, most often through a grand prolongation of the dominant seventh. In addition, the character of the music would signal such a return
Exceptions include the first movement of Brahms's Piano Sonata No. 1, Op. 1. The general key of the movement is C major, and it would then follow that the re-transition should stress the dominant seventh chord on G. Instead, it builds in strength over the dominant seventh chord on C, as if the music were proceeding to F major, only to take up immediately the first theme in C major.
Occasionally, the re-transition can begin with a false recapitulation, in which the opening material of the first theme group is presented in a key other than the tonic. The surprise that ensues when the music continues to modulate toward the tonic can be used for either comic or dramatic effect.

Recapitulation

Recapitulation Haydn's Sonata in G Major, Hob. XVI: G1, I, mm. 58–80.
The Recapitulation is an altered repeat of the exposition, and consists of:
  • First subject group – normally given prominence as the highlight of a recapitulation, it is usually in exactly the same key and forms as in the exposition.
  • Transition – Often the transition is carried out by introducing novel material, a kind of brief additional development section; this is called a secondary development.
  • Second subject group – usually in roughly the same form as in the exposition, but now in the home key, which sometimes involves change of mode from major to minor, or vice versa, as occurs in the first movement of Mozart's Symphony No. 40 (K. 550). More often, however, it may be recast in the parallel major of the home key (for example, C major when the movement is in C minor like Beethoven's Symphony No. 5 in C Minor, op. 67/I). Key here is more important than mode (major or minor) – the recapitulation provides the needed balance even if the material's mode is changed, so long as there is no longer any key conflict.
Exceptions to the recapitulation form include Mozart and Haydn works that often begin with the second subject group when the first subject group has been elaborated at length in the development.
After the closing cadence, the musical argument proper is said to be completed. If the movement continues, it is said to have a coda.

Coda

Coda Mozart's Sonata in C Major, K. 309, I, mm. 148–155.
The Coda is optional. After the final cadence of the recapitulation, the movement may continue with a coda which will contain material from the movement proper. Codas, when present, vary considerably in length, but like introductions is not part of the "argument" of the work. The coda will end, however, with a perfect authentic cadence in the original key. Codas may be quite brief tailpieces, or they may be very long and elaborate. An example of the more extended type is the coda to the first movement of Beethoven's Eroica Symphony.
Explanations for why an extended coda is present vary. One reason may be to omit the repeat of the development and recapitulation sections found in earlier sonata forms of the eighteenth century. Indeed, Beethoven's extended codas often serve the purpose of further development of thematic material. Another role that these codas sometimes serve is to return to the minor mode in minor-key movements where the recapitulation proper concludes in the parallel major, as in the first movements of Beethoven's 5th Symphony or Schumann's Piano Concerto - or, rarely, to restore the home key after an off-tonic recapitulation, such as in the first movements of Brahms' Clarinet Quintet and Dvorak's Symphony No. 9.
