Extended information

Common music beats include one or four beats, two or four beats, three or four beats, four or four beats, three or eight beats, six or eight beats, etc. The length of each section is fixed. The tempo of a piece of music is fixed at the time of composition and will not change.

In music, time is divided into equal basic units, and each unit is called a "beat" or a beat. The duration of a beat is represented by the duration of the note. The duration of a beat can be a quarter note, a half note, or an eighth note (eighth notes are considered one beat).

Music always alternates between strong beats and weak beats. This alternation cannot be chaotic or arranged arbitrarily. Instead, it should be organized into a small section of the smallest beat according to certain rules, and then cycle based on it.
