What is chord?

What Does chord Mean

Chord is a concept that can be used as an adjective or as a noun . In the first case, the term chord 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 profile of the company" , "I do not think they are receiving a salary according to the obligations assigned to me ” .
Suppose an international soccer tournament is held for players under 18 years of age . Of the ten participating teams, nine have squads made up of soccer players between the ages of 16 and 18 . The tenth team, on the other hand, decides to attend the competition with players as young as 13 years old . Given this situation, it can be said that this team would not have had a team commensurate with the magnitude or demands of the tournament, since it would be at a clear disadvantage compared to its rivals.

As a noun, chord is the name given to the set of various sounds that are harmonically combined. In other words: the chord is formed with different musical notes , which sound simultaneously and in harmony .
Chords are usually made up of between three and seven musical notes. The various chords that are part of a composition create a harmonic progression . The songs thus present different harmonic progressions.
It is important to note that there are musical instruments with which you cannot create chords. One of them is the drum which, due to its characteristics, prevents the playing of two or more notes simultaneously.
At the other end is the piano , with which it is possible to play chords and individual notes simultaneously, in addition to applying different styles to the performance. This instrument allows a very high degree of expressiveness to be achieved, as well as 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 it never seems to be at a disadvantage.
The guitar is another instrument on 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 all ten fingers for this purpose. It is the most popular instrument in the Western world, as you don't need great knowledge to play a simple accompaniment. This does not mean that it has little potential; on the contrary, the most difficult concertos can only be performed by the great guitarists.

In this context, especially among people who are 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, as they are two different concepts, as explained above. The source of the confusion is most likely to be found in the fact that they share the first half of their name , as is the case with the C major chord and the C sharp note .
To compose a song it is necessary to choose a tonality, that is, a certain organization of the hierarchy that exists between the pitches of sounds, according to the sound consonance with reference to the so-called tonic , which represents the note, the chord and the diatonic scale. principal. For example, the tone of the minor is, in fact, note the , and the tonic chord is the least ; its scale is characterized by coinciding with the white keys of the piano, like C major .
The ear of musicians automatically accommodates each key, and this allows them to avoid those notes and chords that are not part of it; For example, in A minor it is not possible to play the C sharp note , unless it is an accident duly indicated in the score, which has a defined purpose, such as modulation to another key.
