If you're just starting to dance, it can be tempting to jump into advanced choreography classes. They look super cool, and can definitely get you back into the choreography quickly... But the only way to really feel comfortable doing this kind of choreography is to start from scratch = take a beginner's dance class to learn the basics!
Basic steps are like vocabulary and dance is like a story told.
You're going to need them to be able to express yourself. And even if you're an experienced dancer, you'll still need to go back and reinforce the basics of your moves.
