It is qualified as according to what is appropriate or corresponding.
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 is concordant .
For example: "The medical team found that 70% of the children in the town do not have a weight according to their age" , "We need to hire employees according to the company's profile" , "I don't think they are receiving a salary according to the obligations assigned to me."
Example of using chord as an adjective
Suppose that 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 16 and 18 years old . 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 brought a team in line with the magnitude or demands of the tournament, since it would be at a clear disadvantage compared to its rivals.
A chord is a harmonic combination of sounds.
A combination of sounds
As a noun, chord is 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 .
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.
Chords on different instruments
It is important to note that there are musical instruments with which chords cannot be created. One of them is the drum which, due to its characteristics, prevents playing 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 interpretation. This instrument allows us to achieve a very high degree of expressiveness, in addition to being highly versatile: it can be used as a single instrument, to accompany a singer or as part of an orchestra of varying numbers, and it never seems to be at a disadvantage.
The guitar is another instrument on which you can play chords and melodies; 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 simple accompaniment . This doesn't mean it has little potential; On the contrary, the most difficult concertos can only be performed by great guitarists.
Differences with the note
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, since these are two different concepts, as explained above. The origin of the confusion surely lies 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 . major. For example, the tonic of A minor is, in effect, the note A , and the chord of the tonic is A minor ; Its scale is characterized by coinciding with the white keys of the piano, like C major .
The musicians' ears automatically adapt to each tonality, 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 note C sharp , unless it is an accident duly indicated in the score , which has a defined purpose, such as modulation to another key.
