{{Short description|Musical notation system used in Asia since the 19th century}}
The '''numbered musical notation''' ({{zh|t=簡譜|s=简谱|p=jiǎnpǔ|l=simplified notation}}, not to be confused with the [[Pitch class#Integer notation|integer notation]]) is a [[cipher notation]] system used in mainland China, Taiwan, Hong Kong, and to some extent in Japan, Indonesia (in a slightly different format called "not angka"), Malaysia, Australia, Ireland, the United Kingdom,{{fact|date=August 2021}} the United States and English-speaking Canada. It dates back to the system designed by [[Pierre Galin]], known as '''[[Galin-Paris-Chevé system]]'''. It is also known as '''''Ziffernsystem''''', meaning "number system" or "'''cipher system'''" in [[German language|German]].

==Description==

===Musical notes===
Numbers 1 to 7 represent the [[musical note]]s (more accurately the [[Degree (music)|scale degrees]]). They always correspond to the [[diatonic]] [[major scale]]. For example, in the [[key (music)|key]] of C, their relationship with the notes and the [[solfège]] is as follows:
:{|
| Note: || C || D || E || F || G || A || B
|-
| [[Solfège]]: || do || re || mi || fa || sol || la || si
|-
| Notation: || 1 || 2 || 3 || 4 || 5 || 6 || 7
|}
In [[G (musical note)|G]]:
:{|
| Note: || G || A || B || C || D || E || F{{music|sharp}}
|-
| [[Solfège]]: || do || re || mi || fa || sol || la || si
|-
| Notation: || 1 || 2 || 3 || 4 || 5 || 6 || 7
|-
|Transposed [[Solfège]]:
|sol
|la
|si
|do
|re
|mi
|fa
|-
|Transposed Notation:
|5
|6
|7
|1
|2
|3
|#4 or 4/
|}
When the notes are read aloud or sung, they are called "do, re, mi, fa, sol, la, si". ("Si" has been supplanted in English by "ti", for the sake of having a different beginning consonant for each degree.)

===Octaves===
Dots above or below a musical note raise or lower it to other [[octave]]s. The number of dots equals the number of octaves. For example, "{{underset|•|6|nopadding=yes}}" is an octave lower than "6". Musical scales can thus be written as follows:   
:{|
|- style="vertical-align: bottom"
| Major scale: || 1 || 2 || 3 || 4 || 5 || 6 || 7 || {{overset|•|1|nopadding=yes}}
|- style="vertical-align: top"
| Natural minor scale: || {{underset|•|6|nopadding=yes}} || {{underset|•|7|nopadding=yes}} || 1 || 2 || 3 || 4 || 5 || 6
|}
Where there is more than one dot above or below the number, the dots are vertically stacked: {{overset|•|{{overset|•|1|nopadding=yes}}|nopadding=yes}}

Where there are note length lines (see following section) underneath the numbers, any dots are placed below the lines. Thus the dots below numbers do not always vertically align with each other, since some of them may be moved slightly downward so as not to collide with the note length lines.

===Chords===
Chords can be transcribed by vertically stacking the notes, with the lowest note at the bottom as with Western notation. Each note has its own octave dots, but only the lowest note has the length lines (next section).

Arpeggiated chords are notated by writing the standard Western arpeggiation symbol to the left of the chord.

Chord symbols such as Cm may be used if the exact voicing is unimportant.

===Note length===
The plain number represents a [[quarter note]] (crotchet). Each underline halves the note length: One represents an [[eighth note]] (quaver), two represent a [[sixteenth note]] (semiquaver), and so on. Dashes after a note lengthen it, each dash by the length of a quarter note.

A [[dotted note|dot]] after the plain or underlined note works increases its length by half, and [[double-dotted note|two dots]] by three quarters.

The underline, along with its joining, are analogous to the number of flags and beaming in [[musical notation|standard notation]]. So are dotted notes.
{| class="wikitable"
| Whole (semibreve) || {{nowrap|1 ‒ ‒ ‒}} || Dotted whole || {{nowrap|1 ‒ ‒ ‒ ‒ ‒}} || Double dotted || {{nowrap|1 ‒ ‒ ‒ ‒ ‒ ‒}}
|-
| Half (minim) || 1 ‒ || Dotted half || 1 ‒ ‒ || Double dotted || 1 ‒ ‒ <u>1</u>
|-
| Quarter (crotchet) || 1 || Dotted quarter || 1• || Double dotted || 1••
|- 
| Eighth (quaver) || <u>1</u> || Dotted eighth || <u>1</u>• || Double dotted || <u>1</u>••
|- 
| 16th (semiquaver) || {{double underline|1}} || || || ||
|}

===Musical rest===
The number "0" represents the [[rest (music)|musical rest]]. The rules for length is similar to that of the note, except that it is customary to repeat "0" instead of adding dashes for rests longer than a quarter rest. The bar rest of {{music|time|3|4}} time is {{nowrap begin}}<code>| 0 0 0 |</code>{{nowrap end}} and the bar rest of {{music|time|4|4}} time is {{nowrap begin}}<code>| 0 0 0 0 |</code>.{{nowrap end}} A more general symbol for a bar rest is {{nowrap begin}}<code>| )0( |</code>.{{nowrap end}} The multi-bar rest symbol used in standard notation may also be adopted.

===Undetermined pitch===
When notating rhythms without pitch, such as in many [[percussion instruments]], the symbol "X" or "x" replaces numerals. For example, a common clap pattern used in [[cheerleading|cheers]] can be written like this:

       4/4
 Clap: | X  X  <u>X X</u> X  | <u>X X X X</u> <u>0 </u>{{overset|>|<u>X</u>|nopadding=yes}} {{overset|>|X|nopadding=yes}} ||

===Bar lines===
Bar lines, double bar lines, end bar lines, repeat signs, first- and second-endings look very similar to their counterparts in the standard notation. The ending numbers, though, are usually slightly less than half as big as the numerals representing notes.

When several lines of music are notated together to be sung or played in harmony, the bar lines usually extend through all the parts, except they do not cut across the lyrics if these are printed between the upper and lower parts. However, when notating music for a two-handed instrument (such as the [[guzheng]]), it is common for the bar lines of each hand to be drawn separately, but a score bracket to be drawn on the left of the page to "bind" the two hands together. This bracket is not the same as the bracket used on a Western piano staff; it's more like the bracket used to bind an orchestral section together in Western music. Sometimes the final double barline, and any barlines marked with repeat signs, also pass through both hands, but this is not consistent even in the same publication.<ref>See for example Xinbian Guzheng Jiaocheng {{ISBN|7-5359-2188-4}} pages 108 and 138, where they do and do not pass through both hands respectively.</ref>

If a piece of music for a two-handed instrument has a passage where only one hand is notated, lines of numbered notation without score brackets at the left can be used for this passage.  Hence a piece of music may shift between two-handed (with bracket) and one-handed (without bracket) layouts during the course of the piece.

Cadenza-like passages can have dotted barlines, or barlines can be omitted altogether.

It is possible to print a small fermata above a bar line; this represents a brief pause between the measures either side of the barline, as in Western notation.

===Accidentals and key signature===
The notation uses a [[Solfège#Variations|movable Do (1)]] system. The [[key signature]] defines the [[pitch (music)|pitch]] of "1". So <code>1=C</code> means "C major". Minor keys are based on the [[natural minor]] or the [[Aeolian mode]], and the key signature defines the pitch of "6" of the minor key's [[relative major]]. <code>6=A</code> can be used to refer to A minor, the tonic of which is written as 6. Naturally, the [[Dorian mode]] of D can in principle be marked as <code>2=D</code> and based on 2. In common practice, however, either are normally denoted as <code>1=C</code>.

The same [[Accidental (music)|accidental]]s in the [[musical notation|standard notation]] are used, and as in common practice, an accidental is placed before the notes "1 2 3 4 5 6 7" to raise or lower the pitch and placed after the note names "C D E F G A B", which are used for key signature and [[chord (music)|chord]] markings in the numbered system. But these accidentals are relative to the diatonic scale (1 2 3...) rather than the note names (C D E...). For example, even though the [[leading note]] for the harmonic C minor scale is B natural, it is written as "{{music|sharp}}5".

In the Indonesian version of numbered musical notation known as "not angka", accidentals are notated using right slanted line (like /) to raise the tone a half step and left slanted line (like \) to lower the tone a half step, for example: 1/ read as C{{music|sharp}}, 2/ read as D{{music|sharp}}, 4/ read as F{{music|sharp}}, 5/ read as G{{music|sharp}}, 6/ read as A{{music|sharp}}, 2\ read as D{{music|flat}}, 3\ read as E{{music|flat}}, 5\ read as G{{music|flat}}, 6\ read as A{{music|flat}} and 7\ read as B{{music|flat}}.  In printed not angka, these lines are overprinted on the figures.<ref>[https://github.com/ssb22/jianpu-ly/commit/4e298df57f2d50f0ad40a1b956358462e7d872a5#diff-15b0e0397d48477041da317f9233cef54fe7478371a2f84e107bd403b7221267R312 jianpu-ly not-angka commit line 312]</ref>

Key signature changes are marked above the line of music. They may be accompanied by symbols that represent the note's degrees at previous and present key signatures.

===Time signature===
The [[time signature]] is written as a horizontal fraction: <code>2/4</code>, <code>3/4</code>, <code>4/4</code>, <code>6/8</code>, etc. It is usually placed after the key signature. Change of time signature within the piece of music may be marked in-line or above the line of music. Some pieces that start with cadenza passages are not marked with time signatures until the end of that passage, even if the passage uses dotted barlines (in which case {{music|time|4|4}} time is usually implied).

Sometimes a piece is written with multiple time signatures simultaneously.  For example, it might specify <code>4/4 2/4 3/4 5/4</code>, meaning that the length of measures is irregular and can be 4, 2, 3 or 5 quarter-notes.  The time signature of the first measure is always specified first, and the others are placed in increasing order of length.

Usually, the time signature is formatted as two numbers placed vertically on top of each other, with a horizontal line separating them.  This is slightly different from the formatting illustrated in the text above, due to technical restrictions.

A [[metronome]] mark may be placed immediately after the time signature if the time signature is part-way through the music, or below it if the time signature is at the beginning.  If present, this will be identical to the metronome marks used in Western music (this is the only place in numbered notation where Western symbols for note values such as quarter-notes and eighth-notes are used).

===Expression marks and dynamics===
Expression marks (including fermatas) are also written above the music line.  Special attention has to be paid on the [[staccato]] dot since it looks like the octave changer. It is either represented by a bolder dot further away from the music line or by the [[staccatissimo]] sign instead, which is an inverted triangle.

Dynamics ({{serif|'''''p'''''}}, {{serif|'''''f'''''}}, {{serif|'''''mf'''''}}, etc.) and hairpin crescendos and diminuendos are written below the line of music to which they apply, as in Western notation. The font of the dynamics is usually lighter than the font used in Western notation, so as not to be as heavy as the font for the numbers.

===Fingering and other instrument-specific marks===
Instrument-specific symbols can be written above notes. For example, in music for stringed instruments it is common to see wavy lines representing rolls. Fingering can be marked using four different kinds of finger symbol, respectively appearing like a lightning strike, the top half of a semicircle, a backslash, and the bottom left corner of a square.

Other instrument-specific symbols that are sometimes used include one resembling three slashes progressing diagonally downward, placed to the lower right of the numeral. This represents a tremolo. Another symbol is formed of a line proceeding from slightly to the right of the top right corner of the numeral and curving upwards, ending with the left half of an arrowhead.  This denotes a slide to a higher note (the exact pitch not always being specified), equivalent to [[portamento]] in Western music.

If there are slurs or ties and also fingering symbols, then the fingering symbols are written above the slurs or ties. Rolls (wavy lines) and tuplets are usually written below the slurs or ties. However, if a one-off chord results in many digits being stacked on top of each other and also has a roll symbol, it is possible to place that roll symbol above any slur or tie line to save space (to avoid moving the slur or tie any higher than the chord has already needed to move it).

===Glissandi===
Glissandi are represented by diagonal wavy lines with arrowheads at the end. The [[glissando]] symbol proceeds from bottom left to top right for an upward glissando, or from top left to bottom right for a downward glissando. It is used in place of a numeral. For stringed instruments, it usually indicates playing all the notes of the scale in rapid succession, i.e. for a downward glissando,

:{{overset|•|1|nopadding=yes}} 6 5 3 2 1

and for an upward glissando,

:1 2 3 5 6 {{overset|•|1|nopadding=yes}}

Note that a [[pentatonic]] scale is normally used in Traditional Chinese music, so "all the notes of the scale" in this case are 1, 2, 3, 5 and 6.

Extended glissandi (over several octaves) are also possible, usually written with a longer diagonal wavy line that is nearly touching the numbers on either side of it.  In this case the numbers on either side determine the starting and ending pitches for the glissando.

===Grace notes===
[[Ornament (music)|Grace notes]] are notated like normal notes but are written in a small (about half-size) script on the line just above.  They are written with octave dots and note-length lines, and they are connected to the main note with a slur that proceeds vertically downward from the center of the note-length line of the grace notes and points toward the main note.  Grace notes may be placed either before or after the main note, indicating that they are to be played very rapidly either before the start of the main note or after the end.

==Variations==
In some versions of the numbered musical notation, underlines indicating note length are written above the note instead.  Ties and slurs may be written below the music line.

In some versions, octave change is represented in a different way. Instead of dots above or below the numbers, a horizontal line is drawn and the number is written on, above, or below the line.

Another variation is to put octave bar "|" on the side of the number. An octave bar on the left is equivalent to a dot at the bottom. An octave bar on the right is equivalent to a dot on top. This is used in [https://web.archive.org/web/20180727024539/http://musicmadeeasy.wikispaces.com/Digital+Common+Notation Digital Common Notation]. Digital Common Notation attempts to combine the benefits of the standard notation and numbered musical notation and is targeted for keyboard performing.

==History and usage==
The [[Order of Friars Minor|Franciscan]] priest {{ill|Jean-Jacques Souhaitty|fr}} introduced numbered notation in 17th century. A similar invention was presented by [[Jean-Jacques Rousseau]] in his work presented to the [[French Academy of Sciences]] in 1742. Due to its straightforward correspondence to the standard notation, it is possible that many other claims of independent invention are also true. [[Grove Dictionary of Music and Musicians|Grove's]] credits [[Émile-Joseph-Maurice Chevé|Emile J. M. Chevé]].<ref>Grove Music Online (subscription required but many public libraries are subscribed; URLs vary). China, §II: History and theory.  Alan R. Thrasher, et al.</ref>

Although the system is used to some extent in [[Germany]], [[France]], and the [[Netherlands]], and more by the [[Mennonite]]s in [[Russia]], it has never become popular in the Western world. Number notation was used extensively in the 1920s and 30s by Columbia University, Teachers College music educator [[Satis N. Coleman|Satis Coleman]], who felt it "proved to be very effective for speed with adults, and also as a means simple enough for young children to use in writing and reading tunes which they sing, and which they play on simple instruments."<ref>Coleman, Satis. 1939. Your Child's Music. New York: Van Rees Press:165-171</ref> See the external links for more information.

The system is very popular among some [[Asia]]n people, making conventions to encode and decode music more accessible than in the West, as more [[China|Chinese]] people can sight read ''jianpu'' than standard notation. Most Chinese traditional music scores and popular song books are published in ''jianpu'', and ''jianpu'' notation is often included in vocal music with staff notation. This was first introduced in Japan, later adopted by several Chinese overseas students including [[Hong Yi|Li Shutong]].<ref>{{cite web |first=Mei-Lien |last=Liu |title=音樂簡譜不是毒蛇猛獸 |language=zh |url=https://tamed.yam.org.tw/news05.htm |website=Taiwan Music Educating Association |access-date=19 June 2023}}</ref>

Indexing with numbered notation makes it possible to search a piece of music by melody rather than by title. An actual example can be found in the [[Chinese New Hymnal]]. [[Parson's code]] on the other hand contains information on rise and fall in pitch only but precise pitches can be decoded from numbered notation. This way, a children's song book can be indexed like this:

:<code>|1·&nbsp;&nbsp;1·&nbsp;&nbsp;|1&nbsp;&nbsp;<u>2</u>3·&nbsp;&nbsp;|</code> "[[Row, Row, Row Your Boat]]"
:<code>|1 1 5 5 |6 6 5 ‒ |</code> "[[Twinkle, Twinkle Little Star]]"
:<code>|1 2 3 1 |1 2 3 1 |</code> "[[Frère Jacques]]"

A reason for its popularity among Chinese is that ''jianpu'' fits in with the Chinese music tradition. It is a natural extension and unification of the [[gongche notation|''gongche'' notation]] widely used in ancient China for recording music. ''Gongche'' uses a number of characters to indicate the musical notes, and ''jianpu'' can be seen as using numbers to replace those characters. The [[monophony|monophonic]] nature of music in Chinese tradition also contributes to widespread use because so few elements are needed for monophonic music that music can be notated with little more than a [[typewriter]].

Compared with the standard notation, the numbered notation is very compact for just the [[melody]] line or monophonic parts. It is even possible to transcribe music in between the lines of text. Transcribing [[harmony]] can be done by vertically stacking the notes, but this advantage diminishes as the harmony becomes more complex (or [[polyphonic]]ity increases). The standard notation, with its graphical notation, is better in representing the duration and timing among multiple notes.

==Examples==

The two images below illustrate how the same piece of music is written using the standard notation and the numbered notation.

[[File:AmazingGraceFamiliarStyle.png|center|thumb|800px|The hymn "Amazing Grace" written in standard notation.]]

==ASCII "online Jianpu"==

Since the advent of the Internet and the popularization of [[web browser]]–based communication using common [[Computer keyboard|keyboard]] [[input (computer science)|input]], the "Jianpu" cipher notion has been adopted to easier input formats, including one{{which|date=April 2023}} that utilizes mainly ordinary symbols available on an [[ASCII]] keyboard. For example, the first stanza of "[[Amazing Grace]]" can simply be transcribed as below:{{fact|reason=Please can we have the name of this code and/or a link to somewhere that explains or uses it?|date=April 2023}} 

 / 005 // 
 / 1'0(3'1') / 3'02' / 1'06 / 505 //
 / 1'0(3'1') / 3'0(2'3') / 5'00 / 00(2'3') //
 / 5'0(3'1') / 3'0(3'2') / 1'06 / 505 //
 / 1'0(3'1') / 3'02' / 1'00! / 000 //

==Computing==
A number of Chinese-language [[Microsoft Windows]] applications are available for the [[WYSIWYG]] editing of scores (optionally with lyrics) in numbered musical notation.<ref>[http://www.happyeo.com/intro_jpw.htm JP-Word <span lang="zh">简谱编辑</span>], commercial software with limited demo version</ref><ref>[http://www.medeli.com.cn/soft/gb/soft.asp MeiDeLi JianPu]</ref><ref>[http://www.zuoqu.com/html/jpzy.htm 作曲大师简 (Music Master)]</ref><ref>[http://www.13so.net/ QuickMake Jianpu software (QuickMake <span lang="zh">简谱软件</span>)]</ref><ref><span lang="zh">简谱乐章</span> (Jianpu Yuezhang), apparently no longer distributed by its author but a limited freeware version (<span lang="zh">免费版</span>) is available at various Chinese file-sharing sites</ref><ref>TTComposer (<span lang="zh">TT作曲家</span>) published by <span lang="zh">打本公司</span> 1999–2001</ref> Typically these support only the numbered notation, i.e. it is not possible to mix the numbered notation with a Western-style score in the same [[computer file|file]].  It was possible to add numbered notation to [[Sibelius (software)|Sibelius]] scores via a Chinese-language third-party plugin which is no longer distributed.<ref>[https://web.archive.org/web/20200428211117/http://www.slsgzs.com/jpcj.html Sibelius 简谱插件] (via Internet Archive)</ref>  English-language applications for working with numbered-notation scores are relatively rare, but there have been some developments.<ref>[http://www.a1soft.com/smusic/index.htm S-Music] ([[free software]]; requires [[Microsoft Windows]])</ref><ref>[http://simperhu.weebly.com/ SimpErhu], a freely-available [[TrueType]] font with a set of [[Microsoft Word]] macros for adding numbered notation to documents</ref>

In 2019 a project was started to create a [[cross-platform software|cross-platform]] English-Chinese [[scorewriter]] that can print jianpu, Western or [[tablature]] staves and saves its scores in [[MusicXML]] using [[GNU Lesser General Public License|LGPL]] components.<ref>[https://www.xunscore.cn/index_en.html XunScore Music Notation Editor]. This is currently being distributed closed-source, with a small fee for non-Linux platforms (the payment method requires a China bank card). An x86 Linux binary can be downloaded without charge.</ref>

There are also technical methods of printing numbered notation (in various forms) with [[GNU LilyPond]]. One of them is a converter that converts jianpu to LilyPond notation.<ref>[http://lilypond.org/doc/v2.14/Documentation/notation/note-heads LilyPond documentation: Ez_numbers_engraver]</ref><ref>[https://ssb22.user.srcf.net/mwrhome/jianpu-ly.html Jianpu-ly: convert jianpu to lilypond]</ref><ref>[http://lists.gnu.org/archive/html/lilypond-devel/2009-06/msg00167.html lilypond-user discussion archives: numbered notation using \markup and TeX]</ref>

Duolos SIL Cipher is a free font developed by [[SIL International]] and released under [[SIL Open Font License|OFL]] license, it makes use of [[Graphite (smart font technology)|Graphite]] and [[OpenType]] smart font technologies for laying out Jianpu and [[Kepatihan]], makes it possible to edit and print scores in numbered musical notation with [[word processor]]s, [[desktop publishing software]] and others, although it lacks of support for the slurs in OpenType applications.<ref>{{cite web |title=Doulos SIL Cipher |url=https://software.sil.org/doulos-sil-cipher/ |website=SIL Language Technology |date=23 April 2019 |access-date=23 April 2019}}</ref>

x-Vacle is another OFL-licensed font designed for numbered musical notation using OpenType technology, based on glyphs from other open-source fonts. Unlike Duolos SIL Cipher, it doesn't require extra line height.<ref>{{cite web |url=https://github.com/xPanZuo/x-Vacle |title=xPanZuo/x-Vacle: font about a Numbered Musical Notation (also called Jianpu). |website=GitHub |access-date=19 June 2023}}</ref>

[[Guitar Pro]] versions 8.1 and higher support numbered musical notation.
