The word melody comes from the Greek termmeloidia which means 'to sing'. In our language, the word melody is used to designate a set of sounds that are united or grouped in a special way around a goal: to build a more complex and durable sound that is pleasant to the human ear and that generates in it some type of reaction. The melody can be composed of just a couple of notes as well as an infinity of them, in which case we must understand the melody as a component of musical works.
The melody as an abstract element must then be understood as a set of bass or treble sounds that are ordered in a specific way according to the intention of the composer. Melodies can be found in any situation of everyday life, although in general the disorderly and meaningless conjunction of different sounds (such as a street full of cars, horns and other urban noises) is not understood as a melody. On the contrary, for a melody to be understood as such it must demonstrate a certain organization and construction since that is what proves that the melody was generated in some way and not by chance.
The melody is perhaps the most important thing in any work of music since it is what allows the sounds to sound even in tone (whatever the style of music) and that the final sound is pleasant for the listener. In addition, the melody is also what allows once loose sounds to find continuity and thus something much more complex and interesting can be built. The melodies can be repeated in a varied way throughout a musical work since small variations can be generated on that same structure but always starting from the same point.
