A musical score is a written or printed representation of a composition, showing all the parts that make up the piece and how they relate to one another. It includes notes, rhythms, pitches, dynamics, articulations, and other markings that indicate how the music should be performed by an ensemble or soloist. The score is typically organized into staves, each representing a particular instrument or voice part, with the lines and spaces indicating different musical values. In short, it serves as a blueprint for interpreting and performing a piece of music according to the composer's intentions.
