Five horizontal lines on which notes are placed to show pitch.
Also known as: Stave, Five lines music, Music lines
Five lines and the four spaces between them carry pitch by vertical position. The staff means nothing on its own — a clef has to say what one of its lines is before any note can be read.
Carries pitch by vertical position: each line and each space is one step of the scale from its neighbour.

Settled at five lines over several centuries, having varied between one and many in earlier notation.

Five evenly spaced horizontal lines running the width of the page, with four spaces between them of equal height.
Bar lines divide the staff.
The staff carries the notes; the clef says what its lines mean.
