First of all, you must learn the basic knowledge of music theory. Beat is the soul of music. If the beat is not mastered well, it will be like soldiers who are out of step. For example, if you sing a chorus, you will be out of time (make mistakes).
This process must be done slowly. It is a continuous accumulation and cannot be accomplished in a day. To ensure that the beats are accurate in speed and length, it is best to read the music score and strictly follow the music score requirements to pat the table with your hands (or hold other objects). If you pat the table, it counts as one beat (that is, when you pat down, it is half a beat, and you raise your hand. It's also half time), even for very familiar songs, you can use this to beat the time. If you practice for a long time, you will be rewarded. Just shake left and right with one hand for 2 shots. 3. Draw one hand from top to bottom left, then to the right, and finally from bottom right back to top, just like drawing a triangle.
