How does a five-line staff show the pitch of a musical note?

A five-line staff serves as a visual framework for notating pitch in Western music. It indicates the pitch of a musical note through its vertical placement on the lines or in the spaces between them.1234

To interpret these positions, a clef is placed at the beginning of the staff. The clef acts as a key, identifying the specific pitch of a particular line, which allows a musician to determine the identity of all other lines and spaces.25

The staff functions as a reference for relative height:
* Vertical Placement: Notes placed higher on the staff represent higher pitches, while those placed lower represent lower pitches.24
* Expansion: When a note's pitch falls above or below the five lines, ledger lines are added to extend the range of the staff.26

By arranging notes horizontally, the staff also represents the rise and fall of melody over time, while vertical stacking of notes clearly displays chords.2
