In any piece of music we hear diverse sounds, and in these we must differentiate intonations, current sources and agents or producers. They are called by physicists' qualities of sound: pitch, loudness and timbre.
Tone: Intonation or height of each sound.
Strength: Strength of each sound or set of sounds.
Ringtone: Quality by which we distinguish the source of production of each sound.
For them we have added the term, which allows us to appreciate the phenomenon of sound production.
We remember unnecessary sounds that may occur short or long, more or less, sharp or more or less strong; they can be sung, or produced by any instrument. It high or low does not carry the notion of strong or weak, and so on. Not only with the purely physical properties attributable to the sound, is the work of art music done. Our art set for that three elements are interwoven to achieve the expression are rhythm, melody and harmony. In any piece of music will find these key elements:
Rhythm
It is time management. And this may be more or less symmetrical, more or rhythmic cells less extensive, which may be repeated or not on, but between which our mind tends to establish an order for its perception. Elementarily, this arrangement can be binary or ternary, in twos or threes, and the group of four could be considered as two groups of two, the six, as two groups of three and five, as one of two one of three.
The ear drums this series of orders rather than their duration, intensity or focus. Thus, in a number of drums produced conventionally denoted by a series of points, load intensity those indicated (^).
The binary rhythmic cell would strong-weak, repeated symmetrically. As the ternary cell, it sounds strong-weak-weak rhythm, which is repeated symmetrically. The variety of rhythmic combinations and were systematized by the Greeks in the so-called "foot metric "of his poetry, in which, rather than quantity was long: long syllable and syllable briefly, in their many combinations.
But in music things are complicated because we must also take into account the absence of percussion or sound: silence, which can be critical.
The combinations are thus enlarged. Enough to replace, in that conventional series of dots, some zeros, with what we mean, arbitrarily silence.
We have seen schematically how the music rhythm provides diversification. If the percussion sounds replace them, we will find a vast field where get more music variety.
These basic rhythmic cells (binary and ternary), for ease in carrying out the music, is transformed into so-called "bars". The bars are indicated by figures placed at the beginning of the pattern, or pentagram. They are but expressions of binary cells or ternary or amalgam (binary and ternary or vice versa). Set out as a compass of two by four (Two parts), three of four (three portions), of four parts and other different ways. There are more than relationships or number of musical figures that come in each time and number of parts in ...
