Sheet music is a written representation of music that uses symbols to indicate notes, rhythms, and other musical instructions. It allows musicians to read and perform a piece of music as intended by the composer. Each line and space on the staff represents a different musical pitch, while various symbols indicate how long to hold each note and how loudly to play. Musicians use sheet music for various instruments, including piano, guitar, and violin. It can be found in different formats, such as classical scores, lead sheets, and choral arrangements. Sheet music is essential for learning and sharing music across different genres and styles.
