Prima la musica... poi le parole
A painter hangs his or her finished paintings on the wall for everyone to see. The composer wrote a work, but no one could hear it before playing it. Professional singers and performers have great responsibilities, because composers are totally dependent on them. A music student needs as long and hard training as a medical student needs to become a doctor to become a performer. Most training is related to technology, because musicians must have the muscle proficiency of athletes or ballerinas. Singers should practice breathing every day, because their vocal cords are incomplete without muscle control. String players practice moving the fingers of their left hand up and down while pulling the bow back and forth with their right arm-two completely different movements.
Singers and musical instruments must be able to make every note perfectly in tune. Pianists don't have to worry about this problem, because the notes are already waiting for them there, and Piano tuner has the responsibility to tune them. But they have their own difficulties; The hammers that strike the strings must be coaxed into not sounding like percussion instruments, and each overlapping tone must sound clear.
Obtaining clear texture is a problem faced by student conductors: they must learn to understand every note of music and how it should sound, and they must control these sounds with fanatical but selfless authority.
Technology is useless unless it is combined with music knowledge and understanding. Great artists are those who are so familiar with the language of music that they can play works of any era to their heart's content.
School education and education
In America, it is generally believed that schools are places where people receive education. However, it is said that children today interrupt their education to go to school. The difference between school education and education implied by this sentence is very important.
Education is more open and inclusive than school education. Education has no boundaries. It can happen anywhere, whether in the shower or at work, whether in the kitchen or on a tractor. It includes both formal learning in school and the whole field of informal learning. The media of education can be respected grandparents, people debating politics on the radio, a child or an outstanding scientist. Although school education is predictable, it often brings surprises. Casual conversation with strangers may make a person find that he knows little about other religions. People have been educated since infancy. Therefore, education is a very broad term. This is a lifelong process, a process that begins long before going to school, and a process that should become an inseparable part of one's whole life.
On the other hand, school education is a specific and formal process, and its general model has not changed much in different environments. Throughout the country, children arrive at school at almost the same time, sit in designated seats, be taught by an adult, use similar textbooks, do their homework, take exams, and so on. The realistic fragments to be learned, whether it is the alphabet or the understanding of government operation, are usually limited by the scope of the subjects taught. For example, high school students know that it is impossible to find out the truth about the political problems in their community in their classes, or what experiments new filmmakers are doing. The formal process of school education has certain conditions.
03 Definition of "Price"
Price determines how resources are used. They are also a means of rationing limited supply of products and services among buyers. The price system in the United States is a complex network, which consists of the prices of all products bought and sold in the economy and the prices of countless services, including labor, professionals, transportation and public utilities. The interrelation of all these prices constitutes a "system" of prices. The price of any particular product or service is related to a broad and complex price system, in which everything seems to depend on other things more or less.
If you ask a group of randomly selected individuals to define "price", many people will answer that the price is the amount of money paid by the buyer of a product or service to the seller, or in other words, the price is the monetary value of the product or service agreed in the market transaction. Of course, this definition is valid in itself. To fully understand the price in any particular transaction, you must know more than the amount involved. Buyers and sellers should be familiar not only with the amount, but also with the quantity and quality of products or services to be exchanged, the time and place of exchange and payment, the currency to be used, the credit terms and discounts applicable to transactions, the guarantee of products or services, delivery terms, return privileges and other factors. In other words, both the buyer and the seller should be fully aware of all the factors that constitute the total "package" exchanged for the requested amount so that they can evaluate a given price.
04 electric power
Modern is an era of electricity. People have become accustomed to electric lights, radios, televisions and telephones, and it is hard to imagine what life would be like without them. When there is a power failure, people grope in the flickering candlelight, and cars hesitate in the street. Because there is no traffic light to guide, food goes bad in the silent refrigerator.
However, it was only more than two centuries ago that people began to understand how electricity works. Nature has obviously been experimenting in this field for millions of years. Scientists have found that more and more life worlds may have many interesting electrical secrets that can benefit mankind.
All living cells emit tiny electrical pulses. When the heart beats, it sends out recorded pulses; They form an electrocardiogram, which doctors can study to determine whether the heart works well or not. The brain also sends out brain waves, which can be recorded in EEG. Most living cells produce very little current-usually so small that sensitive instruments are needed to record it. But in some animals, some muscle cells become so specialized that they don't work like muscle cells at all. When a large number of these cells are connected together, the effect may be amazing.
The electric eel is a magic battery. It can generate up to 800 volts of current in living water. The current of an electric house is only 120 volts. ) As many as four-fifths of the cells in the electric eel are dedicated to power generation, and the electric shock it can emit is roughly equivalent to the length of its body.
The beginning of the drama
There are many theories about the origin of ancient Greek drama. The most widely accepted view today is based on the assumption that drama evolved from ritual. The arguments for this view are as follows. At first, human beings thought that the natural forces in the world-even seasonal changes-were unpredictable, and they tried to control these unknown and frightening forces in various ways. Those measures that seem to bring the expected results are kept and repeated until they become fixed rituals. Finally, there are stories that explain or cover up the secrets of the ceremony. Over time, some ceremonies were abandoned, but these stories, which were later called myths, survived and provided materials for art and drama.
Those who believe that drama evolved from ceremonies also believe that those ceremonies contain the seeds of drama, because music, dance, masks and costumes are almost always used. In addition, a suitable venue must be provided for performances. When the whole community does not participate, the "performance area" and "auditorium" are usually clearly divided. In addition, there are performers, and because it is very important to avoid mistakes in ceremonies, religious leaders usually undertake this task. Wearing masks and costumes, they often play other people, animals or supernatural beings, and imitate the desired effects like actors-the victory in hunting or fighting, the coming rain, and the resurrection of the sun. In the end, this dramatic performance was separated from religious activities.
Another theory traces the origin of drama to human interest in storytelling. According to this view, stories (about hunting, war or other feats) are gradually formed. First, the narrator uses imitation, action and dialogue, and then different people play each role. A closely related theory traces drama back to those dances that are mainly rhythmic and gymnastic, or dances that imitate animal movements and sounds.
