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.
The staff is the fundamental latticework of music notation, upon which symbols are placed. The five staff lines and four intervening spaces correspond to pitches of the diatonic scale â which pitch is meant by a given line or space is defined by the clef. In British usage, the word stave is often used.
