A "score" typically refers to a numerical expression that represents the performance or achievement of an individual or group. In various contexts, such as sports, education, or games, a score quantifies success, allowing for comparison between participants. For example, in a basketball game, the score indicates how many points each team has earned. In music, a score is a written representation of a composition, showing the notes and rhythms for instruments or voices. This allows musicians to perform the piece as intended by the composer. A musical score can be complex, containing multiple parts for different instruments, such as piano, violin, or orchestra.
