Music notation is a system of writing for music. The term
sheet
music is used for written music to distinguish from audio recordings. In sheet music for
ensembles, a score shows music for all players together, while parts contain only the
music played by an individual musician. A score can be constructed (laboriously) from a complete set of parts and vice versa.
Present day standard music notation is based on a five-line
staff with
symbols for each note showing duration and pitch in twelve tone
equal
temperament. Pitch is shown using the
diatonic scale, with
accidentals to allow notes on the
chromatic scale, and duration is shown in beats and fractions of a beat.
Origins
There is some evidence that a kind of musical notation was practiced by the Egyptians from the 3rd millennium BC and by others
in the Orient in ancient times.
Ancient Greece had a sophisticated form of musical notation, which was in use from at least the 6th century BC until approximately the
4th century
AD; many fragments of compositions using this notation survive. The notation consists of symbols placed above text syllables. An
example of a complete composition — indeed the only surviving complete composition using this notation — is
the
Seikilos epitaph, which has been variously dated between the 2nd century BC to the 1st century AD.
Knowledge of the ancient Greek notation was lost around the time of the fall of the Roman Empire. Scholar and music theorist
Isidore
of Seville, writing in the early
7th century, famously remarked that it
was impossible to notate music. By the middle of the
9th century, however, a
form of notation began to develop in monasteries in Europe for
Gregorian
chant, using symbols known as
neumes; the earliest surviving musical notation of
this type is in the Musica disciplina of
Aurelian of
Réôme, from about
850. There are scattered survivals from the Iberian peninsula before this time of a type of notation known as
Visigothic neumes, but
its few surviving fragments have not yet been deciphered.
Other types of notation date from the
10th century in China and
Japan. In East Asia, as later in India and elsewhere in Asia, music was notated with the use of characters for sounds. Rhythmic
motifs could also be prescribed in a similar way. In Europe, on the other hand, the foundations were laid for a purely symbolic
notation of music, which does not seem to have been brought to existence anywhere else.
Standard notation described
Elements of the staff
A staff (in
British English, also stave) is generally
presented with a clef, which indicates the particular range of pitches encompassed by the
staff. A treble clef placed at the beginning of a line of music indicates that the lowest line of the staff represents the
note E above middle C, while the highest line represents the note F one
octave higher. Other common clefs include the bass clef (second G below middle C to A
below middle C), alto clef (F below middle C to G above middle C) and tenor clef (D below middle C to E above
middle C). These last two clefs are examples of C clefs, in which the line pointed to by the clef should be interpreted as
a middle C. In a similar fashion, the treble clef points to a G and the bass clef points to an F.
In early music, the clef was written as a letter and its location on the staff was chosen by the writer. The treble clef and
bass clef used today are stylized versions of the letters G and F, respectively. Their locations are now standardized. Unusual
clefs are used for certain requirements, such as the low G clef used for classical guitar music and tenor parts in choral
music.
Following the clef, the
key signature on a staff indicates the key of
the piece by specifying certain notes to be held flat or sharp throughout the piece, unless otherwise indicated. The key
signature is presented in the order of the
circle of fifths, with
flats B-E-A-D-G-C-F and sharps in the opposite order, F-C-G-D-A-E-B.
Another common element of a staff is the
time signature, which
indicates the rhythmic characteristics of the piece. Time signatures generally consist of two numbers; the upper number indicates
the number of beats per
measure (or "bar"), while the lower indicates what sort of
note constitutes a "beat". A time signature of 4/4 (also known as "common
time" and sometimes indicated with a large "C" symbol) implies that there will be four beats per measure, with each beat
constituting a
quarter note. A signature of 2/2 (or "cut time", a "C" with a vertical slash) allows 2 beats per measure, with each
half note lasting a beat. This is important, because the first beat of each bar is
generally stressed. Less commonly, music that lacks rigid rhythmic organization is written without a time signature.
Notes representing a pitch outside of the scope of the five line staff can be represented using
leger lines, which provide a single note with additional lines and spaces. Octave (8va) notation is used,
particularly for keyboard music, where notes are substantially above or below the staff.
Multiple staves can be grouped together to form a
staff system. A system
is used where two staves are required to cover the range of the instrument (as with a keyboard instrument), or where multiple
related instruments are played (as with three violin parts on a score). A score for ensemble music includes multiple systems, as
does most organ music (where the pedals are written as a separate system).
Various directions to the player regarding matters such as
tempo and
dynamics are added above or below the staff, often in Italian (sometimes abbreviated). For vocal music, lyrics are written.
Here is a sample illustrating some common musical notation.

Development of music notation
The ancestors of modern symbolic music notation originated in the Catholic church, as
monks developed methods to put
plainchant (sacred songs) to paper. The earliest of these ancestral systems, from the 8th century, did not originally utilise a staff, and used
neum (or neuma or pneuma), a system of dots and strokes that were placed above
the text. Although capable of expressing considerable musical complexity, they could not exactly express pitch or time and served
mainly as a reminder to one who already knew the tune, rather than a means by which one who had never heard the tune could sing
it exactly at sight.
To address the issue of exact pitch, a staff was introduced consisting originally of a single horizontal line, but this was
progressively extended until a system of four parallel, horizontal lines was standardised on. The vertical positions of each mark
on the staff indicated which pitch or pitches it represented (pitches were derived from a
musical mode, or
key). Although the 4-line staff has
remained in use until the present day for plainchant, for other types of music, staffs with differing numbers of lines have been
used at various times and places for various instruments. The modern system of a universal standard 5-line staff was first
adopted in France, and became widely used by the 16th century (although the use of
staffs with other numbers of lines was still widespread well into the
17th
century).
Because the
neum system arose from the need to notate songs, exact timing was
initially not a particular issue as the music would generally follow the natural rhythms of the Latin language. However, by the
10th century a system of
representing up to four note lengths had been developed. These lengths were relative rather than absolute, and depended on the
duration of the neighboring notes. It was not until the
14th century that
something like the present system of fixed note lengths arose. Starting in the 15th century, vertical bar lines were used to divide the staff into sections. These did not initially
divide the music into measures of equal length (as most music then featured far fewer regular rhythmic patterns than in later
periods), but appear to have been introduced as an aid to the eye for "lining up" notes on different staves that were to be
played or sung at the same time. The use of regular measures became commonplace by the end of the 17th century.
It is worth noting that standard notation was originally developed for use with voice. Proponents of other systems claim that
standard notation is less than ideally suited to instrumental music.

Terms for note durations in American and British English:
In U.S. parlance,
semibreve and
minim are used only in discussions of early music; whole note and half note are used in other
contexts. The
breve is rarely used in baroque and later
eras. When it appears, it is written as oo or |O|.
Effects
According to Philip Tagg (1979, p.28-32) and Richard Middleton (1990, p.104-6) musicology and to a degree European-influenced
musical practice suffer from a 'notational centricity', "a methodology slanted by the characteristics of notation."
"Musicological methods tend to foreground those musical parameters which can be easily notated...they tend to neglect or have
difficulty with parameters which are not easily notated", such as
Fred
Lerdahl. "Notation-centric training induces particular forms of listening, and these then tend to be applied to
all sorts of music, appropriately or not."
Notational centricity also encourages "reification: the score comes to be seen as 'the music', or perhaps the music in an
ideal form."
Other notation systems
Figured bass
Figured bass notation originated in
baroque
basso continuo parts. It is also used extensively in
accordion notation, and for jazz. For continuo and jazz parts, it implies improvisation by the performer;
for accordion, it is used to notate the bass button to be used.
Shape note
The
shape note system is found in some church hymnals, sheet music, and song
books, especially in the
American south. Instead of the
customary elliptical note head, note heads of various shapes are used to show the position of the note on the major scale.
Sacred Harp is one of the most popular tune books using shape notes.
Popular music
Fake books (and the
Real
Books) utilize standard notation, but with key signatures only on the beginning stave, for the melodic line with letter
notation for chord names,
chord symbols, written above.
Improvisation is implied and this system is used for
jazz and
popular music. See
Berklee College of Music.
Letter notation
The notes of the 12-tone scale can be written by their letter names, possibly with a trailing sharp or flat symbol. This is
most often used when speaking about music or writing about it. Letter notation is used to identify chords. In both cases notes
must be named for their
diatonic functionality.
Tonic Sol-fa is a type of notation using the initial letters of
solfege.
Solfege
Solfege is a way of assigning syllables to names of the musical scale. In order, they are: Do, Re, Mi, Fa, Sol, La, Ti, and Do
(for the octave). Other variations are: Do, Re, Mi, Fa, Sol, La, Si, Do, and Fa, Sol, La, Fa, Sol, La, Mi, Fa. See:
solfege,
sargam
Numbered notation
The
numbered musical notation, better known as
jianpu, meaning "simplified notation" in Chinese, is widely used among the Chinese people and probably some
other Asian communities. Numbers 1 to 7 represent the seven notes of the diatonic major scale, and number 0 represents the
musical rest. Dots above a note indicate octaves higher, and dots below indicate octaves lower. Underlines of a note or a rest
shorten it, while dots and dashes after lengthen it. The system also makes use of many symbols from the standard notation, such
as bar lines, time signatures, accidentals, tie and slur, and the expression markings.
Cipher notation
In many cultures, including
Chinese, Indonesian and Indian (sargam), the "sheet music" consists primarily of the
numbers, letters or native characters representing notes in order. Those different systems are collectively know as cipher
notations. The numbered notation is an example, so are letter notation and solfege if written in musical sequence.
Braille music
Braille music is a complete, well developed, and internationally
accepted musical notation system that has symbols and notational conventions quite independent of print music notation. It is
linear in nature, similar to a printed language and different from the two-dimensional nature of standard printed music notation.
To a degree Braille music resembles musical markup languages (http://www.musicmarkup.info/scope/markuplanguages.html) such as
XML for
Music (http://emusician.com/ar/emusic_xml_music/) or
NIFF. See
Braille music.
Integer notation
In integer notation, or the
integer model of pitch, all
pitch classes and
intervals between pitch classes are designated using the numbers 0 through 11, as in modulo 12. It is not used to notate music for performance, but is a
common
analytical and
compositional tool when working with
twelve tone,
serial, or otherwise
atonal music. Pitch classes can be notated in this way by assigning the number 0 to some
note - C natural by convention - and assigning consecutive integers to consecutive
semitones; so if 0 is C natural, 1 is C sharp, 2 is D natural and so on up to 11 which is B natural. The C above
this is not 12, but 0 again (12-12=0). Thus the system represents complete
octave
equivalency. One advantage of this system is that it ignores the "spelling"
of notes (B sharp, C natural and D double-flat are all 0) according to their
diatonic functionality. Thus the system represents complete
enharmonic equivalency.
One drawback is that pitches, intervals, and
simultaneities (chords) are all notated in the same manner. 4, for instance, indicates
the arbitrarily decided fourth pitch (E, if C=0), or two pitches four semitones apart (such as 0 and 4 or 2 and 6). 024
indicates a simultaneity or
succession (such as a melodic fragment) consisting
of three notes, each a
whole tone apart (for example, C, D and E, or G sharp, B
flat and C) and the first and last a
major third apart. This notation may be
used to represent all traditional permutations of a
tone row or set in a
matrix.
The integer model of pitch is one of the basis of atonal or
set theoretical techniques in musical analysis, which now may include
diatonic set theory and
tonal music. It carries an added advantage in that one is able to prove many things, within limits, about pitch
or pitches, and even tonal constructs. Like integers, pitches may be evenly spaced and ordered from lower to higher (lesser to
greater for integers), while many things are not true of both integers and pitch.
Tablature
Tablature was first used in the Renaissance for
lute music. A staff is used, but instead of pitch
values, the fret or frets to be fingered are written instead. Rhythm is written separately
and durations are relative and indicated by horizontal space between notes. In later periods, lute and guitar music was written
with standard notation. Tablature was again used in the late
20th century
and early
21st century for popular
guitar music and other fretted instruments.
Klavar notation
Klavar notation is a chromatic system of notation geared toward
keyboard instruments, that is said by its adherents to be easier to learn than standard notation. A considerable body of
repertoire has been transcribed to Klavar notation.
Graphic notation
Graphic notation refers to the contemporary
use of non-traditional symbols and text to convey information about the performance of a piece of music. It is used for
experimental music, which in many cases is difficult to transcribe in
standard notation. Practitioners include
Christian Wolff,
Earle Brown,
John Cage,
Morton Feldman, and
Roger Reynolds.
Systems not based on the standard 12-tone scale
Other systems exist for non twelve tone
equal temperament and
non-Western music, such as the Indian
svar lippi, along with other alternatives such as
Ailler-Brennink. Some cultures
use their own cipher notations for those music. Sometimes the pitches of music written in just intonation are notated with the
frequency ratios, while
Ben Johnston has devised a system for representing
just intonation with traditional western notation and the addition of
accidentals which indicate the
cents a pitch is to be
lowered or raised.
