Staff (music) In standard Western musical notation, the staff, or stave, [1] is a set of five horizontal lines and four spaces that each represent a different musical pitchâor, in the case of a percussion staff, different percussion instruments.
Music is notated upon the staff in a very logical way. A note increases in pitch as it moves up the staff, and therefore decreases in pitch as it is moved down the staff. A staff of music is read in the same way a line of text is read; from left to right.
