Folk dances are traditional dances that reflect the cultural heritage of a community or nation. They often tell stories, celebrate events, or express the daily life of the people. These dances are usually passed down through generations and can vary widely in style, rhythm, and costume, depending on the region. Many folk dances are performed during festivals, weddings, and other celebrations, bringing people together in a joyful expression of their shared identity. Examples include the Polka from Central Europe and the Bharatanatyam from India. Each dance serves as a way to preserve and promote cultural traditions.
