How does a staff show a note’s pitch?

A musician can read the rise and fall of a tune from marks on a page. A musical staff provides five parallel lines with spaces between them. The oval part of a written note, called its notehead, can sit on a line or in a space. Higher positions generally indicate higher pitches within the same clef.

The clef makes those positions meaningful by providing a reference. In the treble, or G, clef, the second line from the bottom represents the G above middle C. This fixes the surrounding sequence too. The clef is therefore part of the information, not just a decorative mark before the notes.

With this treble clef and no key signature or accidentals, the bottom line is E4, the first space is F4 and the second line is G4. The number identifies the octave. Moving upward from line to neighboring space steps through the note sequence. The example notehead on the bottom line is consequently E4.

The same position can mean a different pitch under another clef, and other notation can alter a pitch. Position alone is not a universal note name. Nor does vertical height show loudness. Staff notation works because readers share both the spatial pattern and its reference, allowing visible marks to carry information about a musical pitch sequence.
