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 pitch—
or, in the case of a percussion staff, different percussion
instruments. Appropriate music symbols, depending upon the intended effect, are placed on
the staff according to their corresponding pitch or function. Musical notes are placed by pitch,
percussion notes are placed by instrument, and rests and other symbols are placed by
convention.
A single vertical line drawn to the left of multiple staffs creates a "system", indicating that the
music on all the staffs is to be played simultaneously. A "bracket" is an additional straight
line joining staffs, to show groupings of instruments that function as a unit, such as the string
section of an orchestra. A "brace" is used to join multiple staffs that represent a single
instrument, such as a piano, organ, harp, or marimba.[2] Sometimes a second bracket is used
to show instruments grouped in pairs, such as the first and second oboes, or the first and
second violins in an orchestra.[3] In some cases a brace is used for this purpose instead of a
bracket.[4][2]
The absolute pitch of each line for a non-percussive stave is determined by the placement of
an appropriate clef symbol at the appropriate vertical position on the left-hand side of the
staff. For example, the treble clef, also known as the G clef, is placed upon the second line
(counting upwards), fixing that line as the pitch first G above 'middle C'.
The lines and spaces are numbered from bottom to top; the bottom line is the first line and the
top line is the fifth line.
The musical staff is analogous to a mathematical graph of pitch with respect to time. Pitches
of notes are given by their vertical position on the staff and notes to the left are played before
notes to the right. Unlike a graph, however, the number of semitones represented by a vertical
step from a line to an adjacent space depends on the key, and the exact timing of the
beginning of each note is not directly proportional to its horizontal position; rather, exact
timing is encoded by the musical symbol chosen for each note in addition to the tempo.
A time signature to the right of the clef indicates the relationship between timing counts and
note symbols, while bar lines group notes on the staff into measures.

[edit] History
An example image with some typical music notation.
The Staff as we know it today originated from musically annotated text, through the
Gregorian Chants around the 12th to 13th centuries. Until this time, symbols were used in
conjunction with text to represent pitch. However, when the chants were written, people
began to use lines to represent pitch, in addition to the pitch symbols above the text. While at
first only one line was used, eventually the system expanded to four lines and used mainly
dots among those lines to represent pitch. However, different numbers of lines were used
throughout Europe for different instruments. France soon began to incorporate five lines into
its music, which became widespread by the 16th century, and was the norm throughout
Europe by the 17th century. The names of the staff in some languages, such as the Italian
pentagramma, reflects the importance of five lines. In 1342, the first music staff was made. It
consisted of four lines and three spaces instead of the modern five and four. Five lines staff
was made in Italy by Ugolino of Forlì.
[edit] Staff positions

The vertical position of the notehead on the staff indicates which note to play: higher-pitched
notes are marked higher on the staff. The notehead can be placed with the center of its
notehead intersecting a line (on a line), or in between the lines touching the lines above and
below (in a space). Notes outside the range of the staff are placed on or between ledger
lines—lines the width of the note they need to hold—added above or below the staff.
Exactly which staff positions represent which notes is determined by a clef placed at the
beginning of the staff. The clef identifies a particular line as a specific note, and all other
notes are determined relative to that line. For example, the treble clef puts the G above
middle C on the second line. The interval between adjacent staff positions is one step in the
diatonic scale. Once fixed by a clef, the notes represented by the positions on the staff can be
modified by the key signature, or by accidentals on individual notes. A clefless staff may be
used to represent a set of percussion sounds; each line typically represents a different
instrument.
[edit] Grand staff
The Grand Staff
When music on two staves is joined by a brace or is intended to be played at once by a single
performer (usually a keyboard instrument or the harp), a great stave (BrE) or grand staff
(AmE) is created. Typically, the upper staff uses a treble clef and the lower staff has a bass
clef. In this instance, middle C is centered between the two staves, and it can be written on
the first ledger line below the upper staff or the first ledger line above the lower staff. When
playing the piano or harp, the upper staff is normally played with the right hand and the lower
staff with the left hand. In music intended for the organ, a grand staff comprises three staves,
one for each hand on the manuals and one for the feet on the pedalboard.
A simple grand staff. Each of the staves shown above have seven notes and one rest.
[edit] Mnemonic devices
There are many different mnemonic devices and songs to help you remember the lines and
the spaces on the staff.
For the treble clef staff, the lines are (from bottom to top) E G B D F and the spaces are F A
C E.
A chant to remember these is: E G B D F are the names of the lines on the treble clef. F A C
E the spaces are easy.
If you would rather have a mnemonic device, E G B D F could be "Elvis's Guitar Broke
Down Friday" (or "Every Good Boy Does Fine") and that the spaces spell FACE.
For the bass clef, the lines are (from bottom to top) G B D F A and the spaces are A C E G.
A mnemonic device to help remember the bass clef lines is "Good Birds Do Fly Away" (or
"Good Boys Do Fine Always") and the spaces could be "All Cows Eat Grass"
For alto clef, the lines are (from bottom to top) F A C E G and the spaces are G B D F
A mnemonic device to help remember the lines on the alto clef is "Frogs and Cats Eat Grass"
and the spaces could be "Good Boys Deserve Fudge"
For tenor clef, the lines are (from bottom to top) D F A C E and the spaces are E G B D
A mnemonic device to help remember the lines on the tenor clef is "Dogs Face A Cat
Everyday" and for the spaces "Eat Good Bananas Daily"
