1, four or four beats:
In the 4/4 beat, the first beat is the strong beat, the second beat is the weak beat, the third beat is the second strong beat, and the fourth beat is the weak beat.
2. Four or two beats:
There are two beats in a bar. The first beat is a strong beat and the second beat is a weak beat. In a bar, there is only one strong beat and one weak beat, and then each bar repeats itself. This 2/4 rhythm is very suitable for parades, so most marches adopt this 2/4 beat form.
In two-beat music, strong and weak laws appear alternately. This law is easier to express the rhythm of music, with strong contrast and strong movement, so it is often used in March or cheerful music, especially in fast-paced music, which can be fully expressed.
The characteristics of the two beats are simple, symmetrical and square. When playing and singing two beats of music, we should accurately grasp its basic law of strength, emphasize its strong beat in the first beat and pay attention to the weak beat in the second beat, so that there is obvious contrast between the two beats and people can feel the rhythm of the two beats in hearing. For example, the songs "Defend the Yellow River", "Red Star Song" and so on.
