Chord definition - What it is, Meaning and Concept

Chord is a concept that can be used as an adjective or as a noun .In the first case, the term according to qualifies that which corresponds to something or that is concordant .

For example: “The medical team found that 70% of the children of the town do not have a weight according to their age ", " We need to hire employees according to the company profile ", " I don't think I'm receiving a salary according to the obligations assigned to me ".

Suppose an international soccer tournament is held for players under 18 years old .Of the ten participating teams, nine have squads formed by soccer players from 16 and 18 years .The tenth team, on the other hand, decides to attend the competition with players just 13 years .Before this situation, it can be said that this The team would not have taken a team according to the magnitude or requirements of the tournament, since it would be at a clear disadvantage against its rivals.

As a noun, according to the name given to the set of several sounds that combine harmoniously.In other words: the chord is formed with different musical notes , which sound simultaneously and in harmony .

The chords are usually composed of between three and seven musical notes.The various chords that are part of a composition create a harmonic progression .The songs , in this way , present different harmonic progressions.

It is important to note that there are musical instruments with which you can not create chords.One of them is the drum that, due to its characteristics, prevents playing two or more notes simultaneously.

On the other end is the piano , with which it is possible to play individual chords and notes simultaneously, in addition to applying different styles to the interpretation.This instrument allows to reach a very high degree of expressiveness, besides being highly versatile: it can be used as a single instrument, to accompany a singer or as part of an orchestra of varied numbers, and never seems to be at a disadvantage.

The guitar is another instrument in which chords and melodies can be played; however, it does not allow the simultaneous execution of as many notes as the piano because the musician does not have his ten fingers for this purpose.It is the most popular instrument in the western world, since it is not necessary to have great knowledge to play a accompaniment simple.This does not mean that it has little potential; on the contrary, the most difficult concerts can only be performed by the great guitarists.

In this context, especially among people fond of the guitar, it is not uncommon to hear the word note to refer to a chord .Needless to say, this is not correct, since these are two different concepts, as explained above.The origin of the confusion is surely found in the fact that that share the first half of their name , as is the case with the do mayor chord and the do sharp note.

To compose a song it is necessary to choose a tone, that is, a certain organization of the hierarchy that exists between the heights of the sounds, according to the sound consonance with reference to the so-called tonic , which represents the note, the chord and the scale main diatonic.For example, the tone of the smallest is, in effect, the note the , and the tune chord is the smallest ; its scale is characterized by matching the white piano keys, as well as do mayor .

The ear of the musicians automatically accommodates each tone, and this allows them to avoid those notes and chords that are not part of it; for example, in the minor it is not possible to play the note do sustained , unless it is an accident duly indicated in the score, that has a definite purpose, such as modulation to another hue.
