Learn the steps by going to a website such as Learn to Dance or Boot Scootin' (links are given below in the "Reference" section). Choose the type of dance you'd like to learn by text. Select "Country Line Dancing" under the heading "Text Lessons.' Follow the dance directions that appear in the order they are listed. The choreography is intended for specific popular country songs, but include moves that are repeated often throughout the various country dances, such as the Grapevine, kick-ball-change and Sailor Steps. Repeat the steps until you feel comfortable enough to practice with the coordinating music playing.
Enhance your country dancing knowledge by watching videos of the dances your learning online. Go to websites such as Line Dance Lessons and Starlight Dance Studios (links given in the "Reference" section below) for videos of the dances you're looking to learn. Search YouTube by typing "Country Western Dancing" or the specific dance such as "Two Step" into the search bar. Watch the video, follow along with the steps. Stop and restart the videos as often as you need to in order to master the steps.
Practice the steps you've learned by alternately reading the steps and watching videos. Review dances consistently to drill the steps into your head. Practice to gain country dancing confidence that will radiate, not just in the comfort of your living room, but in the excitement of country music clubs. Add to your line dance repertoire as your skill increases.
