So now, let's break down the basic Polka. You'll see, as we said before, it's done in a half-step. But, what we want everybody to do is start off with the very basic of Polka is the first step followed by two half steps, two, three. And, then you repeat that on the other foot One, two, three. So, to take that back again. Elaine and I will show you it's one, two, three, one, two, three, one, two, three, one, two, three. But, trust me, we're just warming up for now because the Polka is going to get you hand clapping and toe tapping one, two, three, just like that. Just remember, your first step is a longer step followed by two half-steps. And, it goes like, are we ready? Ready? And, one, two, three, one, two, three, one, two, three, one, two, three. And, you're going to progress around the dance floor. A Polka is a non-stationary dance, which means it moves around the dance floor.
