Breakdancing, also called breaking or b-boying/b-girling, is an athletic style of street dance. While diverse in the amount of variation available in the dance, breakdancing mainly consists of four kinds of movement: toprock, downrock, power moves, and freezes. Breakdancing is typically set to hip-hop, funk, and breakbeat music, although modern trends allow for much wider varieties of music along certain ranges of tempo and beat patterns.
