Gongche notation

Gongche'' notation or gongchepu is a traditional musical notation method, once popular in ancient China. It uses Chinese characters to represent musical notes. It was named after two of the Chinese characters that were used to represent musical notes, namely "工" ''gōng'' and "尺" ''chě''. Since the pronunciation ''chě'' for the character "尺" is uncommon, many people call it gongchi'' notation or gongchipu by mistake.

Sheet music written in this notation is still used for traditional Chinese musical instruments and Chinese operas. However the notation is becoming less popular, replaced by mostly ''jianpu'' and sometimes the standard western notation.

The notes

Basic characters

The notation usually uses a system. There are variations of the character set used for musical notes. A commonly accepted set is shown below with its relation to ''jianpu'' and solfege.

Usual variations

The three notes just below the central octave are usually represented by special characters:

Sometimes "士" ''shì'' is used instead of "四" ''sì''. Sometimes "一" ''yī'' is not used, or its role is exchanged with "乙" ''yǐ''.

To represent other notes in different octaves, traditions differ among themselves. For ''Kunqu'', the end strokes of "上" "尺" "工" "凡" are extended by a tiny slash downward for the lower octave, a "亻" is added for one octave higher than the central. For Cantonese opera, however, "亻" means an octave lower, while "彳" means an octave higher.

Some other variations:
* "尺" is replaced by "乂" in Taiwanese tradition.
* "凡" is replaced by "反" in Cantonese tradition.
* "彳上", the "do" just above the central octave, is usually replaced by "生" in Cantonese tradition.

The following are two examples.

Pronunciation

When the notes are sung in different opera traditions, they do not sound as how the characters are usually pronounced in the respective . Instead, they are pronounced in an approximation of Standard Mandarin pronunciaton. The following is an example from Cantonese opera.

Rhythm

''Gongche'' notation does not mark the relative length of the notes. Instead, marks for the percussion, understood to be played at regular intervals, are written alongside with the notes. Gongche is written in the same format as how Chinese was traditionally written; from top to bottom and then from right to left. The rhythm marks are written to the right of the note characters.

The diagram at the left illustrates how the tune "Old McDonald Had a Farm" will look like if written in ''gongche'' notation. Here, "。" denotes the stronger beat, called "板" ''bǎn'' or "拍" ''pāi'', and "、" denotes the weaker beat, called "眼" ''yǎn'' or "撩" ''liáo''. In effect, there is one beat in every two notes, ie two notes are sung or played to each beat. These notes in solfege with markings will show a similar effect:
:do do do sol la la sol   mi mi re re do



Using this method, only the number of notes within a beat can specified. The actual length of each note is up to tradition and the interpretation of the artist.

Notice that the actual rhythm marks used differ among various traditions.

History and usage

''Gongche'' notation was invented in the Tang Dynasty. It became popular in the Song Dynasty. It is believed to have begun as a tablature of certain musical instrument, possibly using a fixed "do" system. Later it became a popular pitch notation, using usually a movable "do" system.

The notation is not accurate in modern sense. It provides a musical skeleton, allowing an artist to improvise. The details are usually passed on by oral tradition. However, once a tradition is lost, it is very difficult to reconstruct how the music was supposed to sound. Variations among different traditions increased the difficulty in learning the notation.

The system was also introduced to Korea in ancient times and many traditional musicians still learn their music from such scores .
