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.
In most drum notation systems, the lines and spaces of a standard 5-line music staff are used to define the various drums of a kit. For simple parts (for example, a kick and snare pattern) a 1 or 2 line-line staff may be used. Non-kit percussion instruments can be notated on any of these staff types.
