No matter what music, you can draw a square every four or four beats. That is: first, row obliquely downward from top to left, obliquely upward, obliquely rightward, obliquely downward, obliquely upward, obliquely rightward, horizontally leftward, and return to the original starting point. This completes a four-four beat, and then repeats the above action.

This is a simple four-four-beat command method, which can be transformed by yourself after proficiency.
