Dance is an interesting performing art about sequencing human movement.
I always thought rhythmic gymnastics was an interesting art.  It always felt like more of a dance.
Rhythmic gymnastics is interesting because many people manipulate pieces like ropes or hoops. I could see why the rhythmic aspect makes it seem like a dance.
It's been an interesting sport in the Olympics.  I know the Romanians always do well in it.
Some say activities like Dance have a symbolic value that depends on the specific culture in question.
