Music has been called an international language. Why? Because people who do not speak the same tongue can communicate through enjoyment of the same music. Moreover, music has worldwide appeal because it touches just about every aspect of human life. We have love songs, wedding songs, cradle songs, girl and boy songs. We have popular and classical music, Oriental and Western music, folk songs and rock. There is sophisticated music, sometimes with a Latin beat. There is also the very lovely and captivating waltz. And, have you not tapped your toes or clapped your hands in time with a lively polka or a stirring march? Quite likely you have. Yes, a beautiful song that employs a few musical chords appeals to our ears much the same as a fine combination of colors pleases our eyes. Why, even commercial advertising tries to hitch a ride on the bandwagon by setting its ads to music! In some way, due to our makeup as humans, melodious and harmonious sounds can have a deep and emotional impact on us. Especially is this so when they are coordinated with the right tempo, and perhaps accompanied with appropriate words, or lyrics. Music is organized sound. Some of the ingredients used in organizing the sound of music include such things as the musical staff of five parallel lines and their respective ID cards or clef signs. Then there are sharps and flats that alter the character and pitch of the notes without changing their names. The different appearances of the notes indicate varying time or duration of the sounds that they represent. Placed higher or lower on the lines of the staff, they signify higher or lower pitches of sound. This is written music. And the sound of music is the result of someones playing a composers arrangement of these ingredients in suitable patterns. Music is therefore an art form that exists in the realms of sound and time. When sound comes to our ears, something is vibratinga violin string, a drumhead, the reed of a pipe. What happens is that air is set in motion. Like the disturbed surface of a placid pool when a pebble is dropped in, the ripples and waves of air circle out from a source until they make our eardrums pulsateand we hear sound! Without air there would be no sound. We can thank God for our wonderful hearing and all the related creation about us that makes such communication possible. Tones at different pitches are sounded by a wide variety of musical instruments, the earliest of which doubtless was the human voice. When tones are arranged in a recognizable pattern for one voice, the result is melody. Since voice flows like a stream, melody might be said to be horizontal music. If different pitch-sounds are heard simultaneously, as in a chord, harmony has been produced and we may think of harmony as being vertical music. Harmony in music is primarily of two types: concord and discord. Yes, thats right! Discord, or dissonance, as it is sometimes called, is essential to music. Why? Because without dissonance there would be little or no sense of motion or movement to the music. For instance, when a piece of music comes to its end, it gives us the sense of close, or rest. The end has been accomplished, and we are given the feeling of satisfaction.
