Musical notation
Music notation or musical notation is any system used to visually represent aurally perceived music through the use of written symbols, including ancient or modern musical symbols.

Comprehensive music notation began to be developed in Europe in the Middle Ages, and has been adapted to many kinds of music worldwide.
