AI overview
A clef is a symbol placed at the beginning of a musical staff that tells musicians which notes correspond to the lines and spaces on the page. Different clefs (like treble, alto, and bass) represent the same musical notes in different positions, allowing musicians to read music written for their specific instrument.
