Staff (music)
A set of lines and spaces representing musical pitch and time.
In Western musical notation, the staff (UK usually stave; plural: staves), also occasionally referred to as a pentagram, is a set of horizontal lines (usually five) with spaces between them, each representing a different musical pitch. For pitched instruments, the vertical position of a notehead on the staff determines which note to play: higher pitches are placed higher on the staff. Noteheads can be centered on a line or placed in a space between lines. Notes outside the staff’s range are written on or between ledger lines—short lines added above or below the staff. The absolute pitch of each line is indicated by a clef symbol at the left-hand side. For example, the treble clef (G clef) fixes the second line as the G above middle C. The interval between adjacent staff positions is one step in the diatonic scale, and this can be modified by a key signature or accidentals. A percussion staff may have from one to five (or more) lines, where lines and spaces denote different percussion instruments. Guitar tablature uses up to six (or more) lines representing strings. A time signature to the right of the clef relates timing counts to note symbols, and bar lines group notes into measures. A vertical line drawn to the left of multiple staves creates a system, indicating simultaneous performance. A brace joins staves for a single instrument like a piano, while a bracket groups instruments that function as a unit, such as a string section. When two staves are joined by a brace for a single performer, this forms a grand staff (or great stave), typically with a treble clef on the upper staff and a bass clef on the lower; middle C is centered between them. For organ with pedalboard, a grand staff normally comprises three staves. Early Western medieval notation used neumes, which indicated melodic shape without exact pitches, presumably as mnemonics for rote-learned melodies.

Lore & Background
In Western musical notation, the staff (or stave, plural staves), also called a pentagram, consists of a set of horizontal lines—usually five—with spaces between them, each representing a different musical pitch. For percussion, the staff may have from one to five lines (or more), where lines and spaces denote different percussion instruments. In guitar tablature, up to six lines (or more) indicate different strings. Music symbols are placed on the staff so that vertical position shows pitch, percussion instrument, or string, while horizontal position shows approximate timing. The lines and spaces are numbered from bottom to top, with the bottom line being the first. A clef at the left-hand side fixes the absolute pitch of a specific line; for instance, the treble clef (G clef) on the second line upward sets that line as the G above middle C. The staff functions like a graph of pitch over time, though the number of semitones between a line and adjacent space depends on the key, and exact note timing is encoded by note symbols and tempo rather than horizontal proportion. A time signature to the right of the clef relates timing counts to note symbols, and bar lines group notes into measures. Notes outside the staff’s range are placed on ledger lines added above or below. A clefless staff may represent percussion sounds, with each line typically for a different instrument. A vertical line to the left of multiple staves creates a system, indicating simultaneous performance. A brace joins staves for a single instrument like piano or harp, while a bracket groups instrument families (e.g., string section). The grand staff, used for keyboard or harp, joins two staves with a brace, typically treble clef above and bass clef below, with middle C centered between them. Organ music may use three staves for manuals and pedalboard.
Reader's Guide
The staff is fundamental to Western musical notation, providing a visual framework for pitch and time. Its vertical axis represents pitch (higher notes placed higher), while horizontal position indicates approximate timing, with exact timing encoded by note symbols and tempo. The absolute pitch of each line is fixed by a clef placed at the left, such as the treble clef (G clef) on the second line. Key signatures and accidentals modify the notes represented. For percussion, a clefless staff may be used, with each line representing a different instrument. Systems, braces, and brackets join multiple staves to indicate simultaneous performance or instrument groupings. The grand staff (or great stave) joins two staves with a brace, typically using treble and bass clefs, with middle C centered between them. The staff's historical development from neumes to the five-line standard reflects a gradual refinement in specifying pitch and rhythm, enabling complex musical compositions to be preserved and reproduced accurately.
Did You Know?
- The staff is also occasionally referred to as a pentagram.
- In guitar tab, there may be up to six (or perhaps more) lines denoting different strings.
- The treble clef, also known as the G clef, is placed on the second line (counting upward), fixing that line as the pitch first G above middle C.
- The interval between adjacent staff positions is one step in the diatonic scale.
Frequently Asked Questions
What is a staff in music notation?
A staff (or stave) is a set of horizontal lines, typically five, with spaces between them, where each line and space corresponds to a specific musical pitch. In Western notation, symbols are placed on the staff so that vertical position encodes pitch and horizontal position encodes approximate timing.
How many lines does a standard staff have, and can that number change?
The standard staff has five lines, but the count varies by instrument: percussion staves may use one to five or more lines, and guitar tablature can extend to six or more. The five-line format is the most common in classical and popular Western music.
What do the vertical and horizontal positions on a staff represent?
Vertically, a symbol's position indicates pitch, a specific percussion instrument, or a particular string on a plucked instrument. Horizontally, it marks the approximate moment in time when the note or event occurs, functioning much like a pitch-versus-time graph.
How does a clef work on the staff?
A clef anchors a specific pitch to a particular line or space, giving the reader a reference point for all other notes. For example, a treble (G) clef placed on the second line from the bottom designates that line as G above middle C.
What are the alternative names for a staff?
In British English it is commonly called a stave, and it is occasionally referred to as a pentagram. Both terms refer to the same five-line framework used in Western musical notation.
