That depends on what song you choose (or) how much time and an effort you are willing to spends learning to dance. Foxtrot and slow dancing are the most common dances learned by wedding couples, are easy to learn (you can learn enough in one lesson to get out on the dance floor), and work well with slow swing dance songs and ballads. Waltz is very traditional and more formal than Foxtrot Waltz songs are easy to recognized because of their 3 beats measures with a strong an accents on the first beat (123 123). Swing dance is more relaxed and uptempo but still it is an easy to learn in a short amount of time. Salsa, rumba, and cha cha are latin dances that are fun and can be done out at nightclubs but will required for some more time to learn. Tango is very dramatic, but it is one of the more difficult of the partner dances to master.
