If you learn your basic steps well, you’re dancing will excel. The impulse may be to skip the basics or push for more complicated moves; however, more complicated moves are built from the basic steps. In addition, often similar moves exist in different dances with only a change in timing. Therefore, by learning the basic steps in one dance, you can transfer that knowledge when learning another dance. Additionally, simple steps danced on time with styling look better than complicated moves that are out of time or danced without flare and to add syncopation, modifications or chain steps together to make more complex patterns becomes easy once you’ve worked the basic moves.
