The Power Of The Music
The music has always played an important part in the man's history. This is owed partly to that the music, as the Greeks pointed out it, it produces a great effect in the human feelings.
Frequently we can not express with words what makes us feel a music piece, but conform it we listen we will be able to go understanding something of what means. It supposes that you have listened the “Ave María” and that it has been the first time that you hear the song and you don't know the name. In any way you would realize the dignity that contains the melody of this song.
The invention of the phonograph, the radio and the television has taken the music, to all the homes. The young gene likes the music like a hobby for you dance dentender.
The adults like to listen the good music in the concerts. In the entire world people of all the religions are been worth of the music to intone her prayers.
What it produces the sound
If you oppress a key of the piano, you will listen a musical note with a defined modulation. But if you allow to fall this book to the floor you won't listen more than a noise. The noise lacks modulation.
The sound and the noise produce waves you sounded.
In a piano, the sound takes place when the hammers hit the strings, making them vibrate. In the violin the arch slips on the strings and makes them vibrate. In the flute (or the shepherd's old cane) when it is blown in the mouthpiece the air it vibrates in the tube. In a drum, the stretched skin (called head) it vibrates when being hit. When you sing, the vocal chords vibrate in your throat.
In a musical note the vibrations are similar and regular, and they produce certain number of waves per second, as a very quick pendulum. In a noise the vibrations are not regular.
The modulation of a note depends on the speed of the vibrations. Each note produces certain number of vibrations, sharper it is the modulation. To slower vibrations they correspond more serious modulations.
In a piano the most serious tones have the longest strings. The sharpest tones have the shortest strings.
If a rope of certain longitude produces certain tone, another rope of half of its longitude it will vibrate twice quicker and it will produce the same tone, a higher octaba.
This is a scientific law discovered by Pitágoras, among the old ones Greek, and to check this law it constituted an instrument.
