A musical score is a written representation of music that shows the notes, rhythms, and other elements needed to perform a piece. It typically includes staves, which are horizontal lines that indicate pitch, and various symbols that denote dynamics, tempo, and articulation. Composers use scores to communicate their musical ideas to performers. Scores can vary in complexity, from simple melodies for solo instruments to intricate arrangements for orchestras. They are essential for musicians, as they provide the necessary instructions to interpret and play the music as intended by the composer, such as Ludwig van Beethoven or Wolfgang Amadeus Mozart.
