When dancing it is important to look out into the audience and engage them. Even if you aren’t able to do eye contact the whole time, just give it a try every now and then. This will keep them interested in the dance and make it feel more real.
It is a good idea to practice your dance with music at home before your class. This will help you get a feel for the movement and how it goes with the song. This will also allow you to work on transitions and how to flow into each other’s moves.
If you aren’t sure what a certain move is, it is always a good idea to watch your teacher do it first. They will show you how it should be done and may give you a clue as to what part you are missing.
In smooth dances, it is a good idea to keep your pelvic contact light and soft. This will make the movement more graceful. This isn’t always possible in a fast song but it will be a lot more fun to do.
When doing a spin on two beats, it is better to stay on one spot (unless the step requires you to travel) rather than trying to spin and loosing your balance or ending up too far away from your partner and forcing them to chase you or rushing in to close the gap. When kicking, point your feet down and not up (except for some western moves). This looks more balanced and will allow you to cover more ground with your kicks.
