Musical notation is the system of writing and reading music. There are many different synonyms for this term, including sheet music, written music, musical scores, notated music, staff notation, and music script. Sheet music is the most commonly used synonym for musical notation and refers to printed or written music that contains all the necessary information to play a piece of music. Musical scores are similar to sheet music but can also refer to the entire musical composition, not just the written notation. Notated music is a more general term that refers to any kind of music that has been notated, while staff notation specifically refers to the use of staff lines and notes. Music script is a more technical term, often used by musicologists and scholars.
