1. Since the simplified musical notation only uses 7 numbers to represent the entire range, dots are added above and below the numbers to represent an octave higher or an octave lower. This can be expressed directly on the staff. For example, the 1 with a dot on the head can be directly expressed as the note that once occupied the third space above the 7.

2. If a dot is added to the notes in the staff, it will no longer represent an octave higher, but a pause mark, indicating that the note must be played very briefly to show a light feeling. Pay attention to the distinction.

3. The position of the note head determines the pitch, while the shape of the stem and tail determines the length of the beat that the note lasts. For example, a whole note is four beats, a half note is two beats, a quarter note is one beat, an eighth note is half a beat, a sixteenth note is one quarter beat, and so on... Simplified musical notation also has corresponding representations, using are dashes and underlines.

4. The 0 in the musical notation represents the rest of the pause. In the staff notation, it is represented by a special symbol. According to the length of the pause, it is divided into full rest, half rest, quarter rest, eighth rest, Sixteenth rest, etc.

Extended information:

Staves, as the name implies, are composed of five lines. Indeed, it is composed of five parallel "horizontal lines" and four parallel "betweens", and their order is counted from bottom to top.

The first line from the bottom is called the "first line", the second line from the top is called the "second line", and the ones from the top are the "third line" and "fourth line", and finally The top line is the "fifth line".

Since there are so many notes, the gaps between the "lines" must not be wasted. That is, the places between the "lines" and the "lines" are called "spaces", and these spaces are also natural. Counting from bottom to top. Just like the "line", the bottom room is called the "first room", and counting up are the second, third, and fourth rooms.
