Join hands with the other dancers in the line. Standing in your starting position, have your left foot slightly ahead of your right foot.
Cross your left foot over your right, stepping to the right.
Continue to the right by stepping with your right foot, returning your feet to the position you started in.
Repeat the crossover step, trying to keep the beat with the rest of the line. You will now have crossed your left foot over your right twice, and taken four steps altogether.
Kick out your left leg below the knee. Then raise the left leg.
Stomp your left foot on the ground. "Dabke" literally means stomping, so this is the most important part.
Repeat this sequence, moving to your right. The sequence is cross-over, step, cross-over, step, low-kick, raise the leg, stomp.
