Become familiar with Thai dance by watching online videos of different types of it. For example, you can search YouTube for "Thai dance" videos to see the various ways Thai dance is performed. Focus on the dancers' feet and arm movements as well as their costumes. Learn to recognize the differences between the various types of dances. Try them out for yourself at home a few times until you feel relatively comfortable with some of the movements involved in the dances. Visit LearnThaiCulture.com for Thai dance videos as well.
Locate a Thai association or Thai dance company in your area. It may offer Thai dance workshops to the community as a part of its outreach efforts. Attend Thai dance troupe performances to get a firsthand look at Thai dance.
