The national standard dance is divided into Latin dance and modern dance, Latin in the cha-cha, rumba, cowboy, samba, bullfighting, modern in the tango, waltz, Vienna waltz, quick step, fox trot. Latin is the flavor, if you are very lively, very like to show yourself, then you choose this. Modern, then, just the dance costume is like a European noblewoman as elegant and gorgeous, you girls upper body is to have been half lying in the arms of the boys, only the footsteps of the change. I don't know if you will like it. You choose the premise of the national standard, is that you have to love it, take it as a hobby to pay, you will feel his fun.
Generally there will be a dance troupe in the school, you can join, and then find or masters assigned. I suggest you still learn Latin, I think you will like it.
