1. The simplified musical notation consists of seven basic numbers: 1, 2, 3, 4, 5, 6, and 7.

2. For treble, add a dot "." above the number, for bass, add a dot "." below, and for midrange without adding a dot.

3. Add a horizontal line after the number, called an added time line, and do four beats.

4. The next four notes are called whole notes.

5. Next is the half note. A whole note can be divided into two half notes.

6. The last half note can be divided into two quarter notes and two eighth notes.

In addition to being high or low, notes in music also represent length. Here is a basic musical term: beat. Beat is an important concept that represents the length of a note.

Indicates that the length of music requires a relatively fixed concept of time. Notes in simplified notation are divided into whole notes, half notes, quarter notes, sixteenth notes, thirty-second notes, etc. The most important of these notes is the quarter note, which is a basic reference measurement length, that is, a quarter note is one beat.

The concept of a beat here is a relative unit of time measurement. There is no limit to the length of a beat, it can be 1 second, 2 seconds or half a second. If one beat is one second long, then two beats is two seconds; if one beat is half a second, two beats is one second long. Once this basic beat is settled, symbols longer or shorter than a beat are relatively easy
