Floorcraft
The dance floor is divided into two lanes and the center.
1. The outside lane is for faster dancers.
2. The inside lane is for slower dancers.
3. The center is for spot dances.
Line of Dance
Dancers should move around the floor in a counter-clockwise direction. This is known as Line of Dance. You can do moves that require you to go against line of dance, but only for a short distance, and only if the way is clear.
Traveling Dances
Dances that move around the floor are called Traveling Dances. They include Foxtrot, Tango, Waltz, Viennese Waltz, and Quickstep and follow the line of dance. Faster moving dancers take the outside lane, and slower moving dancers take the inner lane.
Spot Dances
Dances that mostly stay in one spot are called Spot Dances. They include Swing, Rumba, Cha Cha, Salsa and Hustle. They are danced in the center of the floor. If a lot of people are doing a spot dance, the inner lane may be danced in. The outer lane should be left open. People may be doing Traveling and Spot Dances to the same song, like Foxtrot and Swing.
Watching Out for Other Dancers
The leader should be watching out for other dancers and protect his lady from bumping into another couple. Likewise, if the lady sees another couple is close behind the leader, she should warn him. When the floor gets crowded you will need to reduce the size of your moves. You don't want your outflung arm to hit anyone. Move off the dance floor to talk and socialize.
