Impact of Oil Spills on the Environment

Impact of Oil Spills on the Environment Oil Spills and Our Environment[MB1] Oil spills have been a major environmental concern when it comes to humans, land and water, aquatic and wild life. Oil can be detrimental to both humans and animals. An oil spill is liquid petroleum that is released into the environment. This happens because of human activity and it is pollution. The word describes aquatic oil spills, where oil is released into the ocean or coastal waters (epa.earthday). These spills may happen on land, as well. When oil is spilled on water it becomes hazardous and endangers our environment and our aquatic ecosystems. The way it pollutes our land is through our resources from our land and the organisms that live below the Earth’s surface. Oil spills are capable of destroying the very life forms that are associated with our food resources. Our environment can be impaired by the physical damages oil causes when animals come into contact with it. The animals can get coated with oil, and with oil being so toxic, it is capable of poisoning organisms that become open to the elements. Oils are not all the same. They have differences, and those differences are petroleum based or non-petroleum based. Oils can have different chemical make ups that give them unique physical distinctiveness. Oils that are Petroleum based can be different varieties of natural hydrocarbon based elements and process petroleum effects. These distinctions will affect the way t hat oil expands and separates. It is good to know the type of oil that one is dealing with because this can help to associate the hazardous dangers that the oil is capable of posing to human and aquatic life. There is also a likelihood that oil is capable of posing a threat to natural and man-made resources, as well (epa). Oils can cause immediate and long-term harmful effects on the environment. They can pose a danger and be deadly to our wildlife. Non-petroleum oils have the capability to diminish the oxygen needed by our aquatic organisms, foul aquatic life, and the feathers of wildlife. Birds can lose their feathers from oil, and the feathers are a vital part of their protective covering. When birds come in contact with oil, it puts the birds in danger of freezing to death or suffocate their embryos. When birds get drenched in oil they transfer oil from the feathers to the eggs. When ingested by fouls through eating, oil can kill them. Some of the other effects of spilled oil on birds and other wildlife consists of suffocation, dehydration, drowning, or starvation. The non-petroleum oils have similarities to petroleum-based oils but they do differ. One of the similarities is that they are both soluble in water and it is limited. Both oils create oil slicks at the surface of water. They both develop mixtures of different substances and sludge’s which looks muddy. Although, non-petroleum oils are known to linger in the environment for a long time. It is also good to remember how they have catastrophic effects on birds and mammals (epa.gov). Immediate response is a necessity when rescuing birds and aquatic mammals. This procedure is not done by just anyone, therefore, training is needed. In order to rehabilitate our oiled wildlife can be a complex procedure. Those who volunteer for this cause must be trained properly, and commit themselves to correctly documented procedures thoroughly, and avoid taking any shortcuts. Also, there must be communication with other agencies in order for the wildlife rescue operation to be a success (greenlivingtips). When birds are brought to the facility oil is flushed from its eyes and intestines immediately. The workers examine to see if they have broken bones, cuts, or other injuries. If the birds that come in have a lot of oil on them, that gets wiped with cloths that absorbs and removes the oil blotches. They are also administered oral medicines that coat their stomachs in case of ingestion. This prevents any other oil to get absorbed into the birds stomach. Once all this is done, the bird is then warmed and isolated within a silent area. In the area where wildlife is taken, curtains are hung around them to limit their contact with humans. Because nutrition is very essential for the recovery of oiled birds, sometimes they must be forced fed until they are able to feed themselves. Once the bird is responsive, stable, and alert, they softly rub a detergent into the bird’s feathers to remove the oil until the oil is gone. Then the bird is rinsed and cleaned and put in a clean, warm, hol ding pen that is covered with curtains. If the bird’s behavior seems normal during observation, then the bird is allowed to swim. They allow this so the bird can preen and realign its feathers. This action restores the feathers to their original structure and helps the bird to become water resistant. The waterproofing test is done prior to freeing a bird back into its natural habitat. They will not release the bird unless it is capable of floating and keeping the water away from its body. This procedure is quickly done because it is toxic the birds and can kill them (greenlivingtips). The Oil Experiment Materials My Prediction Conclusion cotton Will soak up the oil but not be able to clean the oil Oil Spread to cotton and it did not clean up the oil plastic Will get oily and will not be able to clean the oil Plastic became oily and did not clean up the oil newspaper Will soak up the oil but will not be able to clean the oil Oil soaked in paper and it did not clean up the oil paper towel Will soak up the oil but will not be able to clean the oil Oil soaked in paper and it did not clean up the oil feather Will get drenched in the oil, will not be able to clean up the oil Feather became drenched in oil and it did not clean up the oil cotton material Will soak up the oil but will not be able to clean the oil Oil soaked in cotton and it did not clean up the oil nylon material Will become oily itself but will not be able to clean the oil Oil soaked in nylon and it did not clean up the oil string Will get drenched in oil not be able to clean the oil String too small became oily and it did not clean up the oil Dish detergent Dawn Should break down the oil It cleaned up the oil The Conclusion of the Experiment The oil was not easy to clean, although Dawn dishwashing liquid seemed to have the capabilities of breaking the oil down. When I added the oil to the water, the oil floated on the surface of the water. I expected that much because I have seen this before. What I didn’t expect was the fact that the cotton didn’t clean it completely. The oil in water was very difficult to clean up with all my materials except the dawn dish detergent. The material that absorbed the oil the best was the cotton, but it didn’t clean it. It just soaked some of the oil up or expanded it, I’m not quite sure. The material that absorbed the oil the least was the plastic, and the rest of my materials didn’t work either. I used the generic dollar general brand of paper towel. When I used dawn dish detergent, it worked. Oil Spills The Exxon Valdez oil spill is much considered to be the most disastrous oil spill in the world, but as far as the worst environmental disaster in history it doesnt even rank among the top fifty of the recorded largest oil spills. As far as being the oil spill having the worst environmental impact on a region, Exxon is acknowledge. The oil spill caused approximately 11 million gallons of oil to escape from a tankers hull, and it still continues to have an effect on the area. The Alaskan waters known as Prince William Sound has never been the same once the ship hit Bligh Reef (Lovgren). Late at night, on March 24, 1989, a tanker called the Exxon Valdez swerved from the shipping lane in Prince William Sound, Alaska to avoid icebergs and crashed on Bligh Reef. This event was one of the largest oil spill from a vessel in US history at that time. Succeeding spills have leaked out much more. In 1978, four-hundred million gallons of oil was spilled along the coast of Mexico. Another time was 1978, sixty-nine million gallons were spilled by the tanker Amoco Cadiz off Brittany, France. In 1967, a tanker named Torrey Canyon off the English coast spilled thirty-eight million gallons. The tanker Metula in the Straits of Magellan, in 1973, was where sixteen million gallons of oil were spilled. As a result of these oil spills and others, there has been a considerable effort by government, academic and industry scientists to understand the fate and effects of petroleum in our Earth’s waters. One good piece of news that did occur was in 1985, when the National Research Coun cil had reported that they didn’t find any evidence that proves that our oceans environments are threatened by the oil spills. Although, it is still a concern. Petroleum inputs from accidental oil spills were found to be less important contributors to the annual input of petroleum to the aquatic environment than chronic discharges from the urban runoff, industrial waste, and transportation activities. Petroleum, which we now know is one of our natural elements has been naturally discharging in our water in great amounts at many oil outflows around the world. Although, the aftermath of oil spills can be harsh, our natural environment produces effective natural processes that will recovery our environments of most of our oil spills (Alaska). The BP Oil spill was due to an explosion of a rig in the Gulf. There were significant factors prior to the destruction of the drilling of the rig that should have been considered, which was a lack of risk management, at the time. It was a sad time in America from businesses to families and the economy in general. It was said that the incident was an â€Å"accident waiting to happen† (epa.bp). The engineers had identified seven fatal defects that led to the oil spill in the Gulf of Mexico. It was a series of errors that were made by people in critical situations involving complex technological and organization systems. Because of this, it created critical lessons that were learned. It has also given them insights on how to prevent this from happening in the future (epa.bp). The incident lead to the improved risk assessments, and more beneficial regulatory oversight. It called for safer operating procedures and fast crisis response time. The accident was a detrimental and severe lesson learned. Eleven workers lost their lives and seventeen others were injured. The oil spill damaged the economy and environment of the entire Gulf Coast. The laws made changes that will reduce the chances of these tragedies occurring again. These regulation were put in place for both deep-water drilling and high technical and risky industries (oceanworld). The Exxon Valdez leaked out almost eleven million gallons of oil in the pristine Prince William Sound. The oil spread to 1,300 miles of shoreline. The oil spill killed hundreds of thousands of aquatic and wildlife. The difference with the Gulf of Mexico spill is that the oil rig exploded and killed eleven of the workers and produced the largest oil spill in U.S. history. According to NOAA, an estimated two-hundred and ten thousand gallons of oil were leaking oil out of the remaining ruptures in a day. Eleven million gallons spilled by the Exxon Valdez in 1989 in June (greenlivingtips). Environmentalists are working on the long-term environmental impact reduction goals for the areas of energy conservation, resource conservation, and pollution prevention. As far as short term goals are concerned, environmentalists are working hard to advance the broader use of renewable sources of energy, while monitoring and maintaining the carbon footprint of the Earth in hopes that it will be at a m inimum. We can’t completed eliminate all the bad elements in our atmosphere, but we can work together to minimize the issues of concern. A development of a hydraulic fracturing fracking technology is underway, in order to help them obtain accessibility to our natural gas that formerly found to be unreachable (mcclatchydc). Since the BP oil spill, the Environmental Protection Agency has put orders in place that monitor air, water, sediment, and wastes that are produced by the cleaning processes. They will continue the continued response and renovation attempts as well. The government has put a main goal in place too restore and maintain our waters, while providing several causes of action that will be enforceable by the United States in order to  promote the goals. For instance, civil and criminal penalties are put in place as provisions. The CWA has put civil penalty provisions associated  with oil spills and this will provide that penalties recovered under the Clean Water Act must be deposited into the Oil Spill Liability  Trust Fund. Therefore funds will be available in the future or ensure that there are available funds for clean-up, response, and restoration efforts for future oil spills (epa.bp). EarthDay EarthDay is an important day to remember. It will be celebrated on April 22, 2014. This date is the anniversary of the environmental movement of 1970. Gaylord Nelson is the founder who came up with the idea. He was a US Senator in Wisconsin at the time. He witnessed an oil spill in Santa Barbara, California. In his eyes that oil spill was major issue and concern. He waited until an opportunistic time to voice his opinion on the incident. At the time Nelson was trying to find a way to get the news out, there had been a student anti-war movement taking place as well. That is when Mr. Nelson came up with the idea to stimulate the energy given about the war and emerge it with also making the public aware of the water and air pollution, in hopes that it would enforce protection for the environment, and it did. In the end, everyone came together to assist in the cause, and this action led to the four major changes; creation of the EPA and the passage of the Clean Water, Clean Air, and the Endangered Species Act (epa.gov). On April 22, more than a million Americans performed a demonstration on the streets and parks, and held gatherings from the East coast to West coast. They were fighting for the cause, such as, against pollution from factories, power plants, toxic dumps and raw sewage, freeways, and pesticides and most of all the lost that it has caused to the wilderness. Needless to say, in the end he won. Nelson and his followers worked hard to get the government’s attention to environmental issues, and when they did, it was the beginning of the environmental movement. The Environmental Protection Agency was formed on Dec.2, 1970. It was put in place to consolidate a variety of federal research, standard settings, and monitoring, and enforcement activities to ensure that the environment sustains protection for present and future generations The outcome is for Americans to have a cleaner and healthier environment (earthday). The EPA work intensely to make sure everyone is complying to keep the environment clean and free from destruction, and holds those responsible if they are not complying. Because of Earthday, regulations in the Cleveland, Ohio area was forced to clean up the lakes and make sure that there is no hazardous and dangerous elements that can destroy our aquatic life, animals, and human life. Earthday protects our environment and promotes sustainability for our Earth for the future generations to come. It makes us accountable and responsible to keep our environment clean and safe for all living organisms (epa.earthday). I can do my part of protecting our earth by going green. At home, I recycle and utilize bio-degradable products. I will not pollute our waters with pollutants, nor the land. At home I learned to use water, dawn dish detergent, and boiling water to break down cooking oils after cooking so the oils do not build up. At work, I can use less paper products and ride bus to work. During recreation time, I will make sure that I continue to use green products and keep our environment clean from trash and other things that may hurt our environment. [MB1

Impact of looming oil crisis on global trade

Impact of looming oil crisis on global trade The availability of OLL Is taken for granted every day by businesses, governments and individuals alike. However, an oil crisis Is looming and could feasibly hit at any point. This brings back memories of the oil shortages during the asses, which had a major impact on the economic growth, particularly In major Industrial countries such as united States. During the 1973 oil crisis – an embargo initiated by the Organization of PetroleumExporting Countries (OPEC) to protest against some of the American trade practices. As a result of this embargo, the price of oil increased by 300%, causing widespread oil shortages and in some cases forcing petrol stations to close. Experts have warned that similar crisis may be Imminent, with Western countries' presence In the middle east causing friction with some of the countries who are members of OPEC. 011 prices have been Increased In many areas in an attempt to reduce consumption levels and prot ect our natural resources.However, research has indicated that despite these measures the consumption of 011 continues to Increase, with an estimated 89 million barrels of oil being used globally every day. Should a crisis like this hit, the effect on the global economy will be huge – importing materials and goods has become an essential practice for larger organizations, but any increase in oil price would dramatically increase the transportation costs of importing and exporting.As a result, companies would need to either seek cheaper alternatives, or more likely raise the cost of their end product, something which will slow the growth of the economy and prolong the recession. Travel has become a major source of expenditure for large firms, with employees often flying to business meetings Internationally as well as domestically. Budget airlines' turnover has grown throughout the recession as a result of the increase in business travel, however any increase in the cost of oil would force these airlines to pass the costs onto their customers in the form of increased air fares.In the event of another oil crisis, businesses which currently have large travel expenses would suddenly find themselves with vastly increased overheads, and have a sudden need to explore cheaper alternatives which may not suit their business plan. Transportation is by far the biggest cause of oil consumption, with this sector estimated to account for more than half of all consumption worldwide, and more than two thirds of consumption within the US.As well as Increased transportation costs, the costs of operating machinery would also Increase during an OLL crisis, leading to Increases In the cost of many essential items, including foodstuffs. As with the rising cost of transportation, any increase in Experts are unsure when another oil crisis might hit, but most experts agree that a crisis of some sort is likely to occur soon. While the exact effect it will have on the world economy can't be accurately predicted, there is no doubt that businesses of all sizes will need to adapt very quickly to continue trading.

The History of Caklempong

Caklempong traditional music is said to have brought to Malaya by the Minangkabau people of West Sumatra settled in Negeri Sembilan as early as the 14th century. Minangkabau society call the caklempong as talempong. (Source: Abdul Samad Idris, 1970) In the earlier tradition, other than the purpose for fun, caklempong was also played as an important role in everyday life, such as integrating the Minang community residents besides being played during the ceremony of the coronation of the Sultan.Today, caklempong is famously being played for various purposes including the wedding ceremony, opening, entertainment, music accompaniment silat martial, dance and more. Music of caklempong has now been received by the plural society in Malaysia as the nation's musical heritage. Caklempong is now being taught at institutions across the country with a view to inculcate the spirit of love of traditional music in Malaysia THE MUSIC OF CAKLEMPONG Caklempong is included in the group Idiofon (Idiopho ne) that is in the category of musical instruments made of metal, wood, bamboo and coconut shells.It is usually played by hitting, impacting, shaking and pounding. Among the instruments included in this classification are gong, saron (gamelan) bonang (caklempong) kenong (gamelan) angklung, and xylophone. Bonang caklempong has a shape like a small gong made of bronze, 16cm in diameter, 8-10 cm high and 2. 5cm in height cembol midst. Originally, caklempong is played in a pentatonic scale of notation C, D, E, F and G, but it has now include all of the other notations that are A, Bb and B. The complete set of caklempong consists of the following: GeretehGereteh consists of 15 Bonang was written in the tone one octave C Major, including seven not options in the two parallel lines with the 1st line having 8 bonang, while the 2nd line having 7 bonang. Gereteh plays the role of playing the main melody. There are two sets Gereteh in a complete set caklempong. Gereteh Tingkah Tingkah consists of eight pieces that begins with E, F, G, A, Bb, B, C and D. Tingkah focuses on controlling the pace and rhythm produced by the beating of drums. Saua Similar to tingkah, saua consists of eight pieces of bonang. The only difference between tingkah and saua is the way they are played.Saua is played by Ostinato rhythm patterns and moving melodies in the code. Ostinato the notation of saua starts from the note low E. Tingkah / Saua Drum Tambor drum or timber usually made of jackfruit. Leather used is the skin of cattle or buffalo skin. Drum vibration have low (bass) sound. One is known as gendang ibu and the other is known as gendang anak. The role of gendang ibu is to control the tempo whilst the gendang anak creates the dynamic of a certain arrangement. Drum Wooden Armatur The wooden pounder of caklempong is about 22 centimeters long.One third of the wooden pounder is wrapped with rope to the top so that when the sound not too loud when knocking. Wooden Armatur ELEMENTS OF MUSIC Mus ic is an art form whose medium is sound. Common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics, and the sonic qualities of timbre and texture. Rhythm is the flow of music through time. Rhythm has several interrelated aspects: beat, meter, accent and syncopation, and tempo. Beat: is a regular, recurrent pulsation that divides music into equal units of time.When you clap your hands or tap your foot to music, you are responding to its beat. A note may last a fraction of a beat, an entire beat, or more than a beat. More specifically, rhythm can be defined as the particular arrangement of note lengths in a piece of music. The rhythm of a melody is an essential feature of its personality. Meter: In music we find a repeated pattern of a strong beat plus one or more weaker beats. The organization of beats into regular groups is called meter. A group containing a fixed number of beats is called a m easure.There are several types of meter, which are based on the number of beats in a measure. When a measure has 2 beats, it is in duple meter; we count 12, 12, The first, or stressed, beat of the measure is known as the downbeat. A pattern of 3 beats to the measure is known as triple meter. All waltzes are in triple meter, we count 123, 123, etc. Another basic metrical pattern is quadruple meter, which has 4 beats to the measure. As usual, the downbeat is strongest; but there is another stress on the third beat, which is stronger than the second and fourth beats and weaker than the first: 1234, 1234.Upbeat: It is an unaccented pulse preceding the downbeat. Sextuple meter contains six rather quick beats to the measure. The downbeat is strongest, and the fourth beat also receives a stress: 123456. Quintuple meter, with 5 beats to the measure, and septuple meter, with 7 beats to the measure, occur frequently in twentieth-century music and are found occasionally in earlier music. Each of these meters combines duple and triple meter. In quintuple meter, for example, the measure is subdivided into groups of 2 and 3 beats: 123/45 or 12/345.Accent and Syncopation: An important aspect of rhythm is the way individual notes are stressedhow they get special emphasis. A note is emphasized most obviously by being played louder than the notes around it, that is, by receiving a dynamic accent. When an accented note comes where we normally would not expect one, the effect is known as syncopation. A syncopation also occurs when a weak beat is accented, as in 1234 or 1234. Tempo: is the speed of the beat, the basic pace of the music. A fast tempo is associated with a feeling of energy, drive, and excitement.A slow tempo often contributes to a solemn, lyrical, or calm mood. A tempo indication is usually given at the beginning of a piece. As with dynamics, the terms that show tempo (at the left) are in Italian. largo| very slow, broad| grave| very slow, solemn| adagio| slow| anda nte| moderately slow, a walking pace| moderato| moderate| allegretto| moderately fast| allegro| fast| vivace| lively| presto| very fast| prestissimo| as fast as possible| Qualifying words are sometimes added to tempo indications to make them more specific. The two most commonly used are molto (much) and non troppo (not too much).We thus get phrases like allegro molto (very fast) and allegro non troppo (not too fast). A gradual quickening of tempo may be indicated by writing accelerando (becoming faster), and a gradual slowing down of tempo by ritardando (becoming slower). An accelerando, especially when combined with a rise in pitch and volume, increases excitement, and a ritardando is associated with less tension and a feeling of conclusion. Metronome, an apparatus which produces ticking sounds or flashes of light at any desired musical speed. The metronome setting indicates the exact number of beats per minute.Melody: After hearing a piece of music, we usually remember its melody best. melody is a series of single tones which add up to a recognizable whole. A melody begins, moves, and ends; it has direction, shape, and continuity. The up-and-down movement of its pitches conveys tension and release, expectation and arrival. This is the melodic curve, or line. -A melody moves by small intervals called steps or by larger ones called leaps. A step is the interval between two adjacent tones in the do-re-mi scale (from do to re, re to mi, etc. ). Any interval larger than a step is a leap (do to mi, for example).Besides moving up or down by step or leap, a melody may simply repeat the same note. -A melodys range is the distance between its lowest and highest tones. Range may be wide or narrow. -Melodies written for instruments tend to have a wider range than those for voices, and they often contain wide leaps and rapid notes that would be difficult to sing. How the tones of a melody are performed can vary its effect, too. Sometimes they are sung or played in a smoo th, connected style called legato. Or they may be performed in a short, detached manner called staccato.Spiccato: it is a technique used only by string instruments to performe very short notes. -Many melodies are made up of shorter parts called phrases. -A resting place at the end of a phrase is called a cadence. Incomplete cadence: Â  sets up expectations; the second phrase ends with a Complete cadence: Â  gives an answer, a sense of finality. Often the highest tone of a melody will be the climax, the emotional focal point. -A repetition of a melodic pattern on a higher or lower pitch is called a sequence. This is an impelling device of varied repetition that gives a melody a strong sense of direction.Frequently, a melody will serve as the starting point for a more extended piece of music and, in stretching out, will go through all kinds of changes. This kind of melody is called a theme. When folksingers accompany themselves on a guitar, they add support, depth, and richness to t he melody. We call this harmonizing. Most music in western culture is a blend of melody and harmony. Harmony: refers to the way chords are constructed and how they follow each other. -A chord is a combination of three or more tones sounded at once.Essentially, a chord is a group of simultaneous tones, and a melody is a series of individual tones heard one after another. Consonance and Dissonance Some chords have been considered stable and restful, others unstable and tense. -A tone combination that is stable is called a consonance. Consonances are points of arrival, rest, and resolution. -A tone combination that is unstable is called a dissonance. -A dissonance has its resolution when it moves to a consonance. When this resolution is delayed or accomplished in unexpected ways, a feeling of drama, suspense, or surprise is created.In this way a composer plays with the listeners sense of expectation. -Dissonant chords are active and move music forward. Traditionally they have been cons idered harsh and have been used in music that expresses pain, grief, and conflict. Now that consonance and dissonance have been defined, be aware that they can exist in varying degrees. Some consonant chords are more stable than others, and some dissonant chords are more tense than others. Dissonant chords have been used with increasing freedom over the centuries, so that often a chord considered intolerably harsh in one period has later come to seem rather mild.The Triad A great variety of chords have been used in music. Some chords consist of three different tones; others have four, five, or even more. Depending on their makeup, chords sound simple or complex, calm or tense, bright or dark. The simplest, most basic chord is the triad (pronounced try-ad), which consists of three tones. The bottom tone is called the root; the others are a third and a fifth above the root. -A triad built on the first, or tonic, note of the scale (do) is called the tonic chord. The triad built on the fifth note of the scale (sol) is next in importance to the tonic.It is called the dominant chord (sol-ti-re). The dominant chord is strongly pulled toward the tonic chord. This attraction has great importance in music. A dominant chord sets up tension that is resolved by the tonic chord. A progression from dominant chord to tonic chord is called a cadence. The word cadence means both the resting point at the end of a melodic phrase and a chord progression that gives a sense of conclusion. Broken Chords (Arpeggios): When the individual tones of a chord are sounded one after another, it is called a broken chord, or arpeggio.Arpeggios may appear in the melody or in the accompaniment. -The central tone is the keynote, or tonic, of the melody. When a piece is in the key of C, for example, C is the keynote, or tonic. The keynote can also be E, or A, or any of the twelve tones that fill the octave in western music. Key: involves not only a central tone but also a central scale and chord. A piece in the key of C has a basic scale, do-re-mi-fa-sol-la-ti-do, with C as its do, or tonic. Key, then, refers to the presence of a central note, scale, and chord within a piece.Another term for key is tonality. After 1900, some composers abandoned the traditional system, but even today much of the music we hear is built around a central tone, chord, and scale. Practically all familiar melodies are built around a central tone. The other tones of the melody gravitate toward this central one. Since the central tone is especially stable and restful, a melody usually ends on it. Modulation: Change of Key Shifting from one key to another within the same piece is called modulation. A modulation is like a temporary shift in the center of gravity.When the music starts out in the key of C major, for instance, C is the central tone, and the C major scale and chord predominate. With a modulation to G major, G temporarily becomes the central tone, and the G major scale and chord are now the main ones. Though modulations are sometimes subtle and difficult to spot, they produce subconscious effects that increase our enjoyment of the music. Texture: homophonic, Polyphonic, Monophonic Polyphonic Texture Simultaneous performance of two or more melodic lines of relatively equal interest produces the texture called polyphonic, meaning having many sounds.In polyphony several melodic lines compete for attention. (When several jazz musicians improvise different melodies at once, they produce polyphony. ) The technique of combining several melodic lines into a meaningful whole is called counterpoint. The term contrapuntal texture is sometimes used in place of polyphonic texture Polyphonic music often contains imitation, which occurs when a melodic idea is presented by one voice or instrument and is then restated immediately by another voice or instrument.Homophonic Texture: When we hear one main melody accompanied by chords, the texture is homophonic. Monophonic Texture: When we hear one main melody without accompaniment, the texture is monophonic. Form: in music is the organization of musical elements in time. In a musical composition, pitch, tone color, dynamics, rhythm, melody, and texture interact to produce a sense of shape and structure.
