The views on musical notation are as follows:

1. In simplified musical notation, there are seven basic symbols used to express the pitch and relationship of sounds, namely 1, 2, 3, 4, 5, 6, and 7 represent do, re, mi, fa, sol, la, and si respectively.

2. It is impossible to express numerous high and low tones using only seven notes. In simplified musical notation, adding a "·" above the basic note means that the note rises by one octave, which is called a treble; adding two ":" means that the note rises by two octaves, which is called a double. Treble.

Add a "·" below the basic note to indicate that the note is lowered by one octave, which is called bass; add two ":" to indicate that the note is lowered by two octaves, which is called bass. Double bass. There are five registers on the piano keyboard, from left to right, corresponding from treble to bass.

3. Decoration notes: The symbols that represent the rest (pause) of music in music scores are called rests. The rest symbol in simplified musical notation is represented by O. Use "＞" or "□" or "sf" to mark the note, indicating that the note should be sung (played) strongly

When the two marks "＞" and "□" appear at the same time , indicating stronger. The end line uses two vertical lines, one thin line and one thick line in parallel, with the thin one in front and the thick one in the back, indicating the end of the music.

Introduction to the staff:

The staff 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: treble staff, bass staff, soprano staff and alto staff. Staff, lower alto staff.

The soprano clef is not commonly used anymore, the alto clef is only used for viola, and the tenor clef is often used in the higher registers of cello, bassoon, and trombone. In addition, there are alto clefs, mezzo-soprano clefs, etc.
