Hair should be dried with product applied for maximum hold in styling.  Using a large barrel curling iron, wrap hair from base around and up the barrel to achieve spiral curls.  Doing so all along a side parted haircut here and there will result in efforts such as this modern look.  A little spritz of hair spray may prove helpful especially since you will be dancing.
