Quick Answer: What Is Jianpu?
Jianpu (简谱, jiǎnpǔ) is numbered musical notation. The digits 1 through 7 represent scale degrees. A key marking such as 1=C tells you where the sequence begins. Dots can mark octave, and underlines or other signs can mark rhythm.[1][2][3]
- Pitch: Read the number in relation to the stated key.[1]
- Octave: Dots above and below digits can move a note higher or lower.[1]
- Timing: Look for rests, underlines and dashes as well as the digits.[1][2]
The numbers are relative pitches, so the same sequence can be used in more than one key.[1]
The numbers 1, 2 and 3 can describe a rising phrase even before you know how high it sounds. The key marking tells you where that phrase starts. The smaller marks tell you what happens in time.[1][2]
Why the Same Numbers Work in Two Keys
Read 1 as the first scale degree, often called do. In a major-key example marked 1=C, the numbers 1, 2 and 3 are C, D and E. In an example marked 1=G, they are G, A and B. Changing the key moves the phrase to a different pitch level while keeping the pattern of steps.[1]
A number by itself leaves another question open. A high 1 can still be a C in the 1=C example, one octave above the unmarked 1. The octave mark and the intended range of the voice or instrument give the reader more information.[1][3]
How Dots, Underlines and Rests Work
An octave dot above a digit indicates a higher octave. A dot below indicates a lower octave. A dot immediately after a note has a different role. It can lengthen the note. Look first at the position of the dot relative to the digit.[1][2]
A zero marks a rest. An underline beneath a digit can divide the usual beat value, while a dash after a note can add time to it. In a score reproduced by the Hong Kong Film Archive, lyrics sit under the numbered melody and the notation includes rests, dashes and phrasing marks. The line of numerals alone would miss those parts of the performance.[2]
Try this short example in four beats per bar: “1 2 3 – | 0 3 2 1”. Each unmarked number uses one beat. The dash gives 3 a second beat in the first bar. The second bar begins with a beat of silence before the three notes descend. The example keeps the rhythm visible while the key can still change.[1][2]
Where Numbered Scores Are Used
Jianpu spread in China in the early twentieth century after adaptations of European cipher notation circulated through Japan. Today it can appear in published and teaching scores. The Hong Kong Education Bureau compares numbered notation with gongche notation in its materials on Cantonese opera.[3][4]
A study of southern Fujian nanyin describes editions with three forms of notation on the page. Parallel lines can show a reader how two systems describe the same passage, and reveal which features each line records. Likewise, guqin jianzipu can sit alongside a numbered transcription. The digits can give the pitch line and the older tablature can retain the gestures used to make it.[3][5]
FAQs About Jianpu
Does 1 always mean C?
No. It identifies the first scale degree. In a score marked 1=C, it means C. With 1=G, it means G.[1]
Do all dots have the same meaning?
A dot above or below a digit marks octave. A dot after a note can extend its duration. Check the dot’s position before reading it.[1][2]
