When someone goes to a square dance, they partner up with someone. As they are dancing, a person is telling everyone what to do. That may sound easy, but the music is also being played at the same time. The dancers must listen carefully or practice this square dance over and over again in order to know the steps.
Even though the caller is telling you what to do, you will need to know what those steps mean. For example, “do-si-do” is a step that means to pass right around the square from shoulder to shoulder. In the square, there are four couples and each couple is standing next to their partner. Each couple is facing inward. Then the caller starts the steps.
