Our human brain actually responds very obviously and instinctively to a regularly repeated, powerful sounding "beat" and a repeated "rhythm" (you can listen to it The groove from Michael Jackson's "Beat It" and "Thriller").

Although music has several different beats, most of the music we hear is in two or three beats (there are also four beats, but our ears tend to interpret it as two beats in most cases ). So when listening to music, you can consciously pay attention to the "downbeat", which often appears as "accent" (usually hit hard with instruments such as drums). While listening, you can tap with your feet: tap hard on strong beats and tap lightly on weak beats; or tap with your hands, with two beats making a "V" (going down and coming up count as one beat each), and three beats making a "triangle" ( Each side counts as one beat).

In addition, generally the music we hear, especially dance music, basically has clearly identifiable beats and obvious downbeats. But not all music starts with a strong beat, sometimes it may start with a "downbeat".

Finally, listening to music is an ability (including but not limited to listening to beats), which needs to be practiced slowly. Listen to more music and feel more of the "power" of music

Two beats: strong and weak

Three beats: strong, weak and weak

Four beats: strong and weak, then strong and weak
