Musical notation
Musical notation is any system used to visually represent music. Systems of notation generally represent the elements of a piece of music that are considered important for its performance in the context of a given musical tradition. The process of interpreting musical notation is often referred to as reading music.

Distinct methods of notation have been invented throughout history by various cultures. Much information about ancient music notation is fragmentary. Even in the same time frames, different styles of music and different cultures use different music notation methods; for example, classical performers most often use sheet music using staves, time signatures, key signatures, and noteheads for writing and deciphering pieces. But even so, there are far more systems just that, for instance in professional country music, the Nashville Number System is the main method, and for string instruments such as guitar, it is quite common for tablature to be used by players.

The symbols used include ancient symbols and modern symbols made upon any media such as symbols cut into stone, made in clay tablets, made using a pen on papyrus or parchment or manuscript paper; printed using a printing press (c. 1400), a computer printer (c. 1980) or other printing or modern copying technology.

Although many ancient cultures used symbols to represent melodies and rhythms, none of them were particularly comprehensive, which has limited today's understanding of their music. The direct ancestor of the modern Western system of notation emerged in medieval Europe, in the context of the Christian Church 's attempts to standardize the performance of plainsong melodies so that chants could be standardized across different areas. Notation developed further during the Renaissance and Baroque music eras. In the classical period (1750–1820) and the Romantic music era (1820–1900), notation continued to develop as the technology for musical instruments developed. In the contemporary classical music of the 20th and 21st centuries, music notation has continued to develop, with the introduction of graphical notation by some modern composers and the use, since the 1980s, of computer-based scorewriter programs for notating music. Music notation has been adapted to many kinds of music, including classical music, popular music, and traditional music.
