The musical notation 1, 2, 3, 4, 5, 6, 7, the pinyin is do lei mi fa so la qi, and the Chinese character is doleimifasuilaxiduo.

Music notation is a method of recording music using symbols, produced by printing or handwriting. Different cultures and regions developed different notation methods. Notation can be divided into two categories: recording pitch and recording fingering. Staff notation, simplified notation and Braille notation are all musical notations that record pitches. The guitar's six-line notation and the guqin's subtraction notation are both musical notations that record fingerings.

1. In ancient China, there were five tones of "Gong, Shang, Jiao (jue), Zheng (zhi), and Yu", which correspond to 1 2 3 5 6 in the simplified musical notation. They are the basic notes of the music score. These five tones are used in ancient music. When composing music, one of them is used to determine the key. Only in the music will the length of the syllables, quarter notes and notes be reflected. For example, the Yunnan folk song "Little River Flowing Water" was composed in this way. There are no two tones 47 in the whole song, and it is a traditional folk song.

2. Simplified musical notation refers to a simple notation method. There are two types of alphabetical notation and number notation. Generally speaking, simplified musical notation refers to digital musical notation. The digital musical notation is based on the movable solfa method, using 1, 2, 3, 4, 5, 6, and 7 to represent the 7 basic sound levels in the scale, which are pronounced as do, re, mi, fa, sol, la, si , rest is represented by 0. The value name of each number is equivalent to the quarter note of the staff.

The prototype of digital musical notation first appeared in Europe in the 16th century. In the 17th century, French Franciscan priest J.J. Suati improved it and used it to teach religious songs. In the mid-18th century, the famous French thinker J.J. Rousseau made further improvements, vigorously advocated it, and included it in his "Music Dictionary". In the 19th century, after the continuous improvement and promotion of P. Garland, A. Paris and E.J.M. Scheve, it became widely used among the masses. Therefore, this kind of simplified notation is called "Jia-Pa-Xie's notation" in the West.

At the end of the 19th century, simplified musical notation spread to Japan and then to China. The "School Singing Collection" edited and published by Shen Xingong in 1904 was China's earliest self-compiled collection of simplified musical notation. It was then gradually spread to schools across the country. In the 1930s, with the development of the national salvation singing movement, simplified musical notation became widely circulated among the masses.

Because the notation of simplified musical notation is very close to China’s Gongchipu (a type of written musical notation popular in Chinese folk), Chinese simplified musical notation has achieved unprecedented development. On a global scale, China is the The country that has best absorbed and promoted simplified musical notation. The five-line notation, through the Western-centered music education system, has become basically popular in all countries and is one of the compulsory items in schools. It provides the basis for the unification of world music into one notation.

3. Staff notation is a common notation method in the world. A method of recording music on five equidistant parallel lines with notes and other symbols of different durations. Each line of the staff and the space between the lines are called the first line, the second line, the third line, the fourth line, the fifth line and the first room, the second room and the third room from bottom to top. , the fourth room.

If the lines and spaces are not enough, you can add lines and spaces above or below the staff. The added line and the added space are respectively called the upper plus first line, the upper plus first room, the lower plus first line, the lower plus first room, etc., each representing a sound level. The fixed height of these steps is determined by the clef used. There are three types of clefs: treble clef, also known as G clef, bass clef, also known as F clef, and alto clef, also known as C clef.

In order to adapt to the needs of human voices and musical instruments in different ranges, and to avoid excessive addition of lines, there are many kinds of staffs, among which there are five commonly used ones: the treble staff (using G clef) ): Bass clef (use F clef), soprano clef, alto clef, lower alto clef (the latter three use C' clef). The soprano staff is no longer commonly used, the alto staff is only used for viola, and the tenor staff is often used in the higher registers of cello, bassoon, and trombone. In addition, there are alto clefs, mezzo-soprano clefs, etc.

4. Braille notation is a notation method suitable for blind people. There are two types of music notation: six-point music notation (current) and 12-point music notation (innovation). The six-point musical notation was invented by Louis Braille, the father of French Braille. One dot symbol can only express the note name and duration of the musical sound (whole note to 64th note), and the sound group requires another dot symbol. The 12-point music notation was invented on the basis of the "12-point three-pin braille" system. Like simplified notation, one dot notation can express a complete note (duration, note name and pitch), making the music notation more expressive.
