The intensity of the sounds depends on the changes of pressure. To greater pressure differential between the maximum and minimum point of the sound wave, more amplitude will have the sounds. The amplitude is moderate in db (decibels).

The tone of the sounds indicates the acute thing or burdens of such, which depends on the frequency (vibrations per second) of the sound waves. This frequency is moderate in Hertz (herzios). Another concept to consider is the one of timbre or quality of the sound.

The timbre will depend on the different types from overtones that are generated in this instrument.

The frequency is the number of vibrations per second that take place from a sound. They are moderate in Hertz (Hertz). Also the note do (central) has a frequency of 263 Hertz and the following one is famous “the 440” (that is 440 Hertz).

In spite of trying not to extend to us in a as complex subject too much as the one of the sonorous phenomenon, before giving by concluded this brief introduction, we will talk about a pair of questions.

The harmonic composition: or we spoke of the frequency, but it is necessary to consider that an instrument generates a sound complex that gives a note to us which is sumatoria of different frequencies or overtones.

This characteristic would be the one that lacked us to unite previous concepts of frequency both and stamps, since this one I complete it forms according to the overtones that are generated from a fundamental note, and is the reason for which we can differentiate and recognize the sounds of the voices and instruments.
