travel28- The best way to learn the flamenco is to attend a class. Most major cities have flamenco dance lessons for people of all skill levels. Conduct an online search or visit your local community center. They will likely have the information you are looking for.
You can also buy a flamenco dancing video. A good video will show you basic flamenco moves and how to correctly perform them. Videos can be purchased online and at most major retailers.
Purchasing a video is a good way to learn if you are an absolute beginner. You will feel more comfortable attending a class or a club once you have the basics down.
