Polyrhythm - Develop brain exercise, rhythm sense

It is a game playing with Polyrhythm.
Push the button rows of 4 and 3 beats according to the rhythm using the left and right fingers.
At first I went with the slow tempo of the range that I could do. If you get used to it enough, please try to reach the limits by doing it a little faster.
It is confusing not to do separate things separately, but it will gradually become possible.
Also, the impression will be different depending on whether it feels in four beats or three beats. It will be fun to change the beat that you feel in your head as you get used to it.
I came up with this game when I was playing drawing triangle with my left hand and rectangle with my right hand.
Perhaps you can afford it with drums, pianos, string instruments or anything else that is being played. Even if these senses are useful, such as dishes that move separately from each other, they can not.
