From Latin rhythmus, he rhythm is a order matched in the succession of things . It's about a movement controlled or calculated that is produced by the arrangement of different elements.
The rhythm can be defined as the harmonious combination of sounds, voices or words, which include the pauses, silences and cuts necessary to be pleasing to the senses.
The Arts, therefore, they have in the rhythm one of their main characteristics. The literature (both narrative and poetry) has its rhythm in the choice of words and the balance of sentences. For example: a succession of words with long syllables and extensive sentences makes the work have a slow rhythm.
In the case of music , the rhythm is the ratio between the time of a movement and that of a different one. The organization of the measures, the pulses and the accents determine the way in which the listener perceives the rhythm and, therefore, the structure of the work.
Some of the main concepts related to the musical rhythm are:
* the pulse: this is the minimum unit of measurement of time, from a series of pulsations that follow each other constantly to divide time into equal portions. The pulse can be regular or irregular and its speed can be altered within the same work, whether the composer himself indicates it or the interpreters decide. It is worth mentioning that it is essential to perceive the pulse of a work to get into the study of it; Generally, the students of solfeo are worth of small blows with a pencil or with the index finger on a table to represent and analyze it.
* the accent: occurs when a particular pulse is assigned a intensity greater than the rest. It is very important to articulate a musical phrase, both during the study process and at the time of its interpretation in public, since it allows metrics to be organized in a metric manner and brings the performers closer to the intention of the composer, drawing which he intended to show through his works;
* Compass: it is the portion of a musical piece in which the newly exposed points, pulses and accents coexist, the minimum expression of his rhythm. The sequence of pulses, with their respective accents, present in a measure, is repeated throughout the entire work , unless the composer indicates otherwise. This does not mean, of course, that the melody does not vary; the compass is the rhythmic skeleton upon which it rests. There are different ways to classify measures; according to the number of times that make them up, for example, you can talk about binaries, ternaries and quaternaries. Each type of measure has a strong time, which represents the portion that should be accentuated: in the case of a 2/4 measure, the first is strong and the second is weak; for 3/4 (usually associated with the Waltz), times are strong weak weak. Knowing and respecting these concepts is necessary for the study of very complex pieces, since it facilitates the practice by parts and varying the speed to overcome the challenges one by one.
The rhythm can also be detected in the natural processes , as the periodic succession of phenomena geophysicists Ocean tides and lunar months are events linked to rhythmic processes.
In everyday language, rhythm is associated with speed What do you live with: “My vacations had a frantic pace: I toured five countries and I didn't spend more than two days in any city”, “I like going to the countryside to visit my grandparents, because they live at a much quieter pace and I can rest”.
