Staff notation is a system of musical notation used to indicate the pitch, rhythm, and tempo of a piece of music. It is composed of five elements: a REST, a CLEF, a gclef, a staff, and a time signature. A REST is a symbol that indicates a pause in the music. A CLEF is a symbol that indicates the pitch of the notes on the staff. A gclef is a variation of the CLEF that is used to indicate higher pitches. The staff is a set of five horizontal lines that are used to indicate the pitch of the notes. Finally, the time signature is a symbol that indicates the meter of the piece. Together, these five elements form the basis of staff notation.
