Professional words are rhythm. The rhythm of rumba is two three four one, or two three cha cha to be exact. Samba is one two three four. You can hear it if you listen carefully. If it's not very professional, I'll tell you one trick, that is, listen to it according to the style. When you hear these three kinds of dance music, what touches you most is rumba music, which has a compact rhythm and a fast speed. Lively music is just right, with a strong sense of rhythm and strength. Very sexy music is samba music. In fact, you can practice by listening to more songs. Besides, I can give you some music if you need it. Three steps, four steps? This belongs to ballroom dancing, not Latin dancing. Latin dance is a dance with strong aesthetic feeling and strength. The biggest difference is that Latin dance has a long history, so it has formed many styles, which are naturally very aesthetic and can be compared with step 3 and step 4 at a glance.
