It depends on what kind of dance you are dancing. Let's take two dances with different rhythms as an example:

Street dance:

Hip-hop, jazz, breaking and house are different dances, but the rhythm of the music is similar.

The interval between drums of hip-hop music is the same, as shown in the text:

"dadada dadada"

Yes, except for the speed difference, as long as the distance between drums in a song is the same.

Latin:

Latin includes rumba chacha, cowboy bullfighting and so on. , and their beats are different, for example, it is precisely:

"two ~ three ~ just one"

Although its drum spacing is different in each bar, it is almost the same in a song.

So if you want to step on the scene, you must listen to the drum distribution of a song, and you can enter at any point.

If you still don't understand anything, you can add me qq and I'll play you a song.
