Changes in Movie and TV Art Brought by Sound
    Movies and TV are complete arts combining seeing and hearing. In that way, what kind of function does sound perform in movie and TV art? Furthermore, how many potentialities does it have in art creation? Soulie, a French artist, dwelt on the concept in his book Cue at Art. He states that there are artistic factors in how people feel about sound because sound can be very illusive in our imagination. Moreover, movement and rhythm in the physical world produces a variety of sounds. We use these sounds to describe what we have seen. Physiologically, through our sense of hearing, we can analyze several outdoor sound simultaneously, synthesizing different sounds. So we may say, in comparison, visual images come to us in straight lines. However, the sends of hearing is perceived from all directions.
    As we all know, movies and TV plays are formed by many factors, including both pictures and sounds; the former is continuously flat, the latter, on and off. In addition to technical processing in a movie, the sound can be used to describe the environment, serve as a foil to the atmosphere, and connect the shots, and endow the pictures with the functions of montage, which creates an artistic correction that picture alone can't show. Also, it brightens the picture by adding or dotting by emphasizing or exaggerating or replenishing. However, it can't take precedence over the picture, instead, it should be used to attract the regulated atmosphere created by the directors and strengthen the reality and appeal of the picture as more green leaves to beautiful flowers. All in all, the figure on the screen is being accompanied by wound for the imagination. For instance, a moving car has its unique sound, just as the sea does. Psychology shows that sensation is the basis of perception, perception is formed by sensation, and through perception people get the reflection of the objects. The sound we hear is particularly characteristic although our ears can't distinguish it quite as well as our eyes distinguish images. Everyone has the ability to observe pictures and distinguish sounds. One can also imagine the picture through sounds so as to thoroughly understand the theme of the move. In summary, the sound brings changes to move and TV art as follows:

• It makes the picture reflect reality more accurately and look more alive;
• It reduces the limitation of the picture and directly reflect the aural world in life;
• It enriches the movement in the art, not only emotional motion of music, but also the reasoning motion of language;
•   It changes the function of montage;
• It enlarges the dimension and depth of the picture so that the implied meaning is wonderfully expressed;
• It not only enriches TV rhythm but also makes the scene more complicated and more delicate;
• Music is used in the creation of new production; and
• It makes the silent freehand an art work and the means of showing the TV theme.

    In his book, Outline of Scenario, Professor Wand, Liu of Beijing Film Institute states, "Visual space is always combined with sounds of real life. Only when they are can people obtain the scene of reality."
    In other words, sound shapes movie and TV art into a deep and broad world, rich in gradation, space, and color, and devotes visual figures to the audience in a natural way.

The Function and Usage of Sound in Movie and TV Art
    With the development of modem life, sound has become important for reasoning and feeling, making it extremely important in move and TV arts. Within sound there are both realistic and abstract styles. Realistic sound refers to any natural sound except dialogue and music. By expressing and symbolizing, it exceeds its information and its accompanying pictures. For examples, there is a set of shots to introduce the noisy early morning scene in a workers' dormitory after they have awakened. By utilizing our rich imagination, we can change the natural sounds and the produced sound into new and brilliant sound space, then take the subjective artistic refinement and the aesthetic study on wound into our conceiving, so that we can change the way that gives subjective shots to subjective sounds. That is, we should edit the natural sounds such as irregular footsteps, shouting, singing, splashing of water from the faucet, the opening and closing of doors, the chopping of vegetables, etc., and record them together in gradations to form a specific kitchen symphony in the dormitory. This is a good way to play up the circumstance with reality. The above-mentioned view show that the vividness of realistic sound lies in creating the environment with reality to strengthen the appeal of the theme of the picture. The other feature of the realistic sound is to produce gradation and density of screen space. We may also say it is to recall the sound. It can produce a three-dimensional illusion of the sound. In other words, it can make distant object small and their sounds vague, or vice versa. So, the strong and vivid three-dimensional sense of the sound closely links the illusion with the environment. For instance, words can't be heard clearly, or al all, if in a bustling street or a noisy fair. However, some tiny sounds will seem to be clear and loud during a silent night. Consequently, these principles are used in move and TV art. In conclusion, realistic sound has the following actions:

• Its vividness conquers the audience;
• It enlarge the view-space and breaks the limitation of the picture; It makes use of the emotional atmosphere of the environment;
• It can strengthen the motion of the image;
• It produces a greater three-dimensional sensation; and
• It describes the figures are their characteristics by the volume of the sound and the rhythm of their motions.

    Abstract sound, including artistic sound and the subjective processing of the sound, will give a new artistic conception, or become some kind of potential information whose effect cannot be produced by language alone. Just as time and space in the movies have broken the bonds of reality and of the stage, seeking freedom, abstract sound is becoming a unique artistic techniques, with specific artistic ways of adding color to the screen.

The Usage of Music in Movie and TV Art
    The visual and auditory senses must be combined to analyze the music in movie and TV art, not analyzing the function of music alone, but with the perspective of the artistic effect of their combination.
    Exaggerating the atmosphere
    The visual figure of a picture's atmosphere will be as monotonous as a flat surface unless modified by sound. Given sound and music, it will be set off an fully developed. Because of three-dimensional sense, the atmosphere stands out, causing one to feel personally on the scene. Here is an example. There is a Chinese-produced television documentary named Talking About the Canal ("Canal;" refers to the Jingling Can4 the longest in China). At the beginning of the first section called "The Disappearance of the Canal". an anxious atmosphere is shown in one section of the canal where it was terribly lacking of water. In the picture, the whistling wind shakes the trees, with leaves falling down, signing, followed by many dry and useless riverbed and water conservancy projects... All these scenes bring out a moving atmosphere. This is accompanied by a piece of thoughtful music. With the uneasy color added by the roaring of the fall wind, the melody wanders forward lie a series of gentle waves, playing up the atmosphere that the picture tries to describe and adding color to the moving and exiting visual motion. The use of music and sounds suddenly shortens the distance between regulated atmosphere and one's emotion and make the audience feel they are right there. Thus, in a splendid and effective way, the music connect the picture and the sound to exaggerate the atmosphere.
    Revealing and deepening the theme
    In movie and TV production the picture should express a certain theme. Music as a form of art, can do as well. Usually, a TV show or TV series has one, even several main melodies, which will summarize and deepen the theme when they are continuously repeated. As a matter of fact, these melodies or musical themes point out the theme with musically notes through the auditory sense. For instance, opening theme songs always accompany a picture in the form of instrumental music, which shows, strengthens, and deepens the theme. In other words, it is the core use of music in the picture, and it is outside effect which plays up or exaggerate the atmosphere. The essential purpose of adding music to the picture is to show and deepen the theme.
    Using music to replace sound
    Sound and music are closely related because both make timber the basic information. The tone color of music resembles natural sound very much. For example, the music of a piano or sharp sounds resemble flowing waters; the music of wood wind instruments sound like singing birds; and the low-pitched instruments sounds are like heavy footsteps. Because of these likenesses, music can replace sound and exactly express implied meaning. Essentially, sound that is added to the scene refines and sublimates the natural sound in a wonderful manner. That is why music is moving and beautiful, much better than natural sound. For instance, in Cultural Origin of the Rivers (A Chinese-produced documentary), there is a piece of music used to describe the sound of a herd of rushing antelopes. By violently striking the drum, with the flash-rhythm of stringed instruments, the composer creates a scene filled with sounds of hoofs and clouds of dust. The vivid description of the sound of antelopes' hoofs differs from the natural ones. With a little exaggeration and the countless beauty of art, it is not a replacement but an artistic combination of music and sound. All in all, the function of music in movie and TV art is the comprehensive artistic effect produced by combining visual art and auditory art. These functions or effects are produced not only for the natural characteristics of music, but for the combination of pictures and sounds. Therefore, we can actively master the features and strong point of TV music by analyzing, researching, accumulating, and discussing all these function. In this manner, improved skills will achieve more complete artistic effects.
