**Notation** is the **action and effect of noticing** (to point, to warn, to point). The term comes from Latin and refers to the system of **signs** conventions that are adopted to express some concept.

It is known as **Scientific notation** By representing a number using powers of base ten. In this sense, **numbers** are written as the product of a real number called **coefficient** (which can be equal to or greater than 1 and less than 10) times 10 raised to an integer called **Magnitude order** or **exponent**; this is represented by the formula *ax 10 raised to n*.

The **mathematical notation** it is the formal symbolic language that follows its own conventions. The **symbols** They allow to represent concepts, operations and all kinds of mathematical entities.

In chess, the notation is a **system** game registration that allows transmitting the movements made by the players. There are two types of notation: **descriptive** (which is currently in disuse) and the **algebraic**.

The algebraic chess notation identifies each of the seventy-four squares on the board with two **characters**. The first one refers to the column and is represented by the letters from the *to* to *h* lowercase, ordered from the left of the player who moves the white pieces to his right. The second character identifies the line or row of the box, with the numbers from the *1* to the *8* in ascending order, that is, from least to greatest.

The writing system used to represent a **musical piece** graphically it is called **musical notation**, and allows each interpreter to perform a certain piece following the ideas and indications of the composer and the reviewers. Currently, the most common method is based on the use of **staff** (five parallel horizontal lines) with the notes expressed by signs that indicate their duration and height.

The musical notation used in the West has undergone an important evolution over more than two millennia, beginning as a basic system that made use of symbols from the Greco-Latin alphabet and reaching the current methods, of a more abstract nature and with **a much greater range of possibilities**. In any case, it has always been a very complex matter, since it transcends the mere indication of the height of each **sound** to put on paper a very extensive series of characteristics, such as the rhythm (called tempo), the duration of each note, its intensity (wrongly called *volume*, especially in the context of music equipment and televisions), its articulation and its character, among others.

It is worth mentioning that the **developing** One of the different systems that have been used over so many centuries was affected both by the growth of art itself and by political, social and religious issues. It is known that the ancient Greeks already made use of musical writing, but it was not until the Middle Ages that the system was created that, after hundreds of years, would become the one we know today.

Using a score allows *immortalize* a composition at a level that exceeds (both in complexity and precision) that of an audio recording. One of the reasons is that it not only offers the necessary tools to specify every detail of the work, but also gives the composer the possibility of expressing a series of suggestions for the execution, which may or may not be accepted by **interpreters**.

Finally, it is interesting to note that not all **instruments** They use the same notation system; for example, for guitar parts the so-called **tabs**, which facilitate reading, since they represent the strings with six lines.
