The musical staff symbol is composed of four parts: a NOTE (4 letters), a CLEF (4 letters), a REST (4 letters), and a gclef (5 letters). A NOTE is a sign used in musical notation to represent the relative duration and pitch of a sound. A CLEF is a symbol placed at the beginning of a staff line in musical notation to indicate the pitch of the notes written on that line. A REST is a symbol used in musical notation to indicate a period of silence. A gclef is a CLEF that indicates the position of the G NOTE on the second line of the staff.
