1, first introduce the four most common beats: full tone (* * * four beats), semitone (* * * two beats), quarter note (one beat) and eighth note (half beat).

2. When I was a child, in music class, the teacher taught us to beat time by hand. Open it, close the high five, and then open it (back to its original position). These two "off and on" actions constitute a beat.

The principle of tapping with feet is the same. Let's first introduce the preparation posture of tapping with feet (also in the original position), as shown below, the feet follow the ground and the toes are inclined. Toe down for half a beat; The tiptoe is lifted back to its original position, which is also a half beat; That toe fell to the ground and then rose back to its original position. This is a beat.

4. The concepts of one beat and half beat are introduced above. Those two beats and four beats are easy to understand: the toes are down, and then they rise to the original position twice, that is, two beats; Press your toes down on the ground and lift it back to its original position four times, which is four beats.
