Development of Piano essays

Development of Piano essays The piano is the most popular instrument. It is not too much to say that more people know how to play the piano than any other instrument. The history of making the piano and piano technique has had a lot of development since the 18th century. There were many forms of piano system and techniques in earlier times. A lot of attempts and efforts since then have created a well-done and popular instrument, which is the modern piano. The piano is an instrument which makes sound with vibrations. The hammers in the piano strike the strings, and then the vibration of the strings is transmitted to a soundboard. Even though the sounding system of early and modern piano is pretty similar, there are some differences between of them. Modern hammers are covered with felt, but early hammers were covered with leather. The modern piano has a cast-iron frame capable of withstanding the tremendous tension of the strings which makes a louder sound than earlier ones. On the other hand, early piano had wood frames and could only lightly string. These are only examples of differences between past and present pianos. In fact, there are many differences between the two kinds of instrument. The first piano was invented by Bartolomeo Cristofori. He conceived Gravecembalo col piano e forte, which is a harpsichord which can produce soft and loud sounds, in 1709. In the mid-18th century, the piano had become widely popular. Also, the composers who wrote for the piano such as Wolfgang Amadeous Mozart and Muzio Clementi, were in an important position because the development of a specialized piano style of playing and composing helped make the piano popular. Around 1860, the square piano was replaced by upright piano which was made with the design of upright harpsichords with the strings rising from keyboard level. Actually, the upright piano was very tall, but it was made shorter and more suitable for small rooms by Hawkins later. ...

The World is So Big, Yet So Small

The World is So Big, Yet So Small We sit in our chairs behind desks or at the kitchen counter on our laptops, and feel protected from the world yet a part of it. The shy parts of us try to convince us that we are just as connected as if we were on tour. The web has joined us all together. Then we wonder why we dont have followers, or why we arent selling books. Anyone can throw up a blog. Anyone can buy an ad, and goodness knows anyone can toss a book on Amazon. All of that does little for your platform. That is . . . unless you have a blog that knocks the socks off people thanks to your controversial way of presenting things, or your works wax ridiculously lyrical. Blogging about your life, your day, your thoughts on writing . . . how is that different from the next one hundred blogs What Im trying to say is there is nothing magical about putting yourself out on the web. Followers dont suddenly find you because you purchased a domain name and hired someone to build you a WordPress site. You arent Kevin Costner, and people dont come to your blog because you built it. If Ive learned anything in the book side of my profession, its that people want to see you. Ive spoken to a room of three hundred or as few as two. Some appearances are more predictable than others, but the truth is you present with the same quality and passion. These folks are there to see you, experience you, learn from you. You might be amazed at how much they appreciate you putting yourself out there, with some of the most loyal fans coming from small events. Most of my strongest supporters have met me. From a library in Bettendorf, Iowa to a writers conference in a rec center cafeteria in Wadesboro, North Carolina. From the basement of a bank in Black Earth, Wisconsin to the sun porch of a home in Newberry, South Carolina. When you meet people, make eye contact, and read their body language, you form a more memorable bond. The writer becomes real, more worthy of endorsement because they took the effort to be there in the flesh. That took planning, driving, the cost of travel. Be willing to genuinely meet people. Dont hide in a string of twenty authors. Be willing to smile and share a minute with a stranger. Dont forever hide behind your screen. Yes, the world is huge, but making the effort to shrink it and stretch your social skills with a handshake and real conversation forges long-time fellowship. Thats the strongest platform you can create. And you dont have to travel the globe to find it. Your hometown venues work just fine.

Education as Ideological Management Essay Example | Topics and Well Written Essays - 500 words

Education as Ideological Management - Essay Example Succeeding minority groups had the same problem with inequality, wherein the pervading culture of white, Protestant and Anglo-Saxon continued to view Native Americans, Asian Americans, Latinos, and other minority groups a threat to the dominant ideology. While the past was characterized by blatant policies of racism and inequality, the current period is an era where the question of self-awareness and self-examination of where ideological biases could be examined. It is not as much as American education deliberately perpetuates racism but in the way ideology is carried unconsciously, spreading biases and prejudice even to those who are themselves considered minorities. For example, colored people may unconsciously imbibe the cultural and ideological biases of the dominant cultural group, thereby undermining their very sense of identity. Culture has a pervasive impact on the educational system, embedded not in just the way teachers teach, but in the systemic practices.

The Piazza of San Marco Essay Example | Topics and Well Written Essays - 1500 words

The Piazza of San Marco - Essay Example The essay "The Piazza of San Marco" explores The Piazza of San Marco, the heart of Venice. This is where the famous Grand Canal, the largest canal in Venice takes its beginning from and where the most popular sights are located. The square is very old and has its roots as far back as in the ninth century. It was created then as a small space in front of the Saint Mark’s Basilica, and later, in 1777, it was extended and preserved its size up to nowadays. As we are to compare the condition of the Piazza in the Renaissance (approximately in the year 1500) and nowadays we should mark that, according to the information above, the square remained in its original size at the time of making the map of Jacobo de Barbari and the painting by Gentile Bellini. Nevertheless, i should be mentioned that in the painting of another artist, Giovanni Antonio Canal, square has the same look as in the modern times. To add more, it is notable that the square isn’t actually a square, it is a t rapezoid (Imboden).Regarding the general composition, the location of the buildings haven’t changed over centuries, but the details have. The architectural dominant of the Piazza is the Doge’s Palace, a building that used to serve as a residence for Venetian Doges. The palace is built in Italian gothic style. The first building appeared at that place back in the ninth century and looked as a fortress. In 976 this building was burned as a result of the rebellion, and later rebuilt in 1106. The major part of the modern palace.

South Wales in the 1930s :: Papers

South Wales in the 1930s 1. Sources 1 and 2 give many reasons for poverty in South Wales in the 1930s, Unemployment however being the most significant as it was the cause of almost all the poverty in South Wales at this time there were a number of causes for unemployment listed in source 1 such as:- Ã…Â ¸ The collapse of the post-war economic boom Ã…Â ¸ Increased competition from abroad Ã…Â ¸ The General strike Ã…Â ¸ The decline in the mining and steel industries Ã…Â ¸ The great depression All of these factors caused mass unemployment in South Wales in the 1930s almost to the point where nearly three quarters of the population in South Wales were unemployed. Source 2 indicates that all hope had left the unemployed and their want to find work may have almost deteriorated from constant rejection causing possibly their want to keep a decent standard of living to slowly decline into poverty. 2. Poverty affected the people of Wales in many different ways, Source three indicates that it had a dramatic change in peoples political views, it depicts a miners hunger march to Bristol in 1931, the marchers are shown to be carrying a banner bearing the communist hammer and sickle with the words "struggle or starve" written on in this is also an acronym for sos. Although the miners are on a hunger march to show the poverty in south Wales we notice they are well dressed this is because the miners were a proud people, they did not want to beg the government they just wanted to show that they were starving and that they needed work and help to get back on their feet for themselves. There is almost a sort of irony in this picture as these miners are photographed marching past food signs, perhaps the photographer was trying to depict the ignorance of the rest of the country to the miners predicament. Source four describes the anger over the "Means Test" and a protest about this privacy invasion.

Question: How the concentration of acid (HCl) can be determined by titrating it using base (NaOH)? Essay

How the concentration of acid (HCl) can be determined by titrating it using base (NaOH)? Chemicals needed: 1- Phenolphthalein (color indicator). 2- Sodium hydroxide (NaOH) concentration of 0.5 molar. 3- Hydrochloric acid (HCl), with unknown concentration. Equipments needed: 1- Flask. 2- Pipette (uncertainty à ¯Ã‚ ¿Ã‚ ½0.05cm3). 3- Burette (uncertainty à ¯Ã‚ ¿Ã‚ ½0.05cm3). 4- PH meter. 5- Gloves, lab coat and plastic eye protection. Steps: 1- Add a known volume of HCl using pipette in the flask. 2- Add 2 drops of phenolphthalein in the flask using the pipette. 3- Shake the flask until the color changes to red. 4- Start to add NaOH on the HCl, drop by drop. 5- After each drop shake the flask to accomplish the mixing of the acid with the base. 6- Take readings of PH value using the PH meter, after each drop. 7- When HCl color turns to blue, immediately stop adding NaOH, this indicates the neutralization point. 8- To be sure that HCl is neutralized add few drops of NaOH on HCl. 9- Repeat the experiment to obtain more accurate data. Data collection and processing: The table below shows the values of PH recorded over the five trials and indicates the neutralization point at a specific volume of NaOH added: (1.0) table shows the data collected during the trials Below is the table produced after changing the volume of NaOH to the better measurable unit, also after adding the PH values for each volume added of NaOH then divide them by the number of trials to come out with the average PH value. (1.1) table showing the processed data Average PH value 0.0193 13.3 0.0194 13.4 0.0195 13.5 0.0196 13.5 0.0197 13.5 0.0198 13.5 0.0199 13.3 0.0200 07.3 0.0201 01.7 0.0202 01.5 0.0203 01.3 The graph below shows the graphical relationship between volume of NaOH added in dm^3 versus average PH value: As calculated at the neutralization point which is nearly equal to 7, the volume of NaOH added is approximately 0.0250 à ¯Ã‚ ¿Ã‚ ½ (0.0000450) dm^3 To calculate the concentration of base, it is most desirable to use the equation below: Now substituting the concentration, also volume of the acid (HCl) and the volume added of the base (NaOH), then: 0.6 Molar Conclusion and evaluation:- Conclusion: – It is concluded that the concentration of HCl in the lab that all the trials occurred in is 0.6 Molar. – It is concluded that titration of acid using base must be repeated many times to accomplish more accurate results. Evaluation: – The usage of a digital PH meter may affect the accuracy of the data, as it produces systematic errors. – The volume of phenolphthalein may play a role on the volume of HCl in the flask. – Concentration of NaOH may not be exactly 0.5 molar as there might be impurities. – The PH value as shown from the data collected is changing at a high manner near to the neutralization point; therefore it is not easy to know the precise concentration of NaOH. – Calculating the PH value to indicate the rate of reaction, is not precise, because the PH has a logarithmic function not a linear function, then there will be a small change in the PH value while there will be big change of H+. Improvements: – Using a digital instrument to drop exactly 1.0 cm^3 in each drop. – Using a base with primary standard to titrate HCl may be more accurate to indicate the value of it is concentration. – Using a pipette with less uncertainty may help in improving the data collected. – Using a burette with less uncertainty can determine more accurate results.

The First Major Investigation Of Elder Abuse Incidence Study

The first major investigation of elder abuse in the U.S. was in 1996. This study was called The National Elder Abuse Incidence Study. This study found 449,924 people over the age of sixty had been abused. There were five different forms of neglect that had been explored, emotional, physical, sexual, potential neglect, and financial abuse. These numbers are not accurate, because a lot of these incidents are not reported. Data showed that approximately 1,000,000 adults living the U.S had been abused. Studies conducted in Canada and Great Britain also showed a large percentage of physical and verbal abuse amongst the elderly. In 1996, 3005 individuals between the ages of 57-83 were surveyed, asking about different types of abuse that happened over the years. There was 9% prevalence of verbal abuse, .2% physical abuse, and 3.5% financial abuse. Females and those who were frail were the ones who experienced more verbal abuse. African Americans were more likely to experience financial ab use. In 2010 another study was designed to build and expand researcher from the 1996, National Elder abuse incidence study. This study was designed to understand the mistreatment among elders living in the U.S. This study was designed to assess the different types of abuse over one year prevalence.
