Dancers usually begin by toprocking, and then continue by going down to the floor and performing a 6-step or 4-step that may be heavily 'teched' (variated).
After performing a 6-step to begin the dance, and then performing a power move, the breakdancer will usually end the dance with a 'freeze' which is when he moves his body to a strange position and literally freezes, stopping all dance motion.
The breakdancer will usually hold the freeze for a second or two. There are nearly infinite variations on freezes, and coming up with new freezes greatly enhances the breakdancers style.
