Ceilidh dancing is a traditional form of social dance originating from Scotland and Ireland. It typically involves groups of people dancing together in a lively and energetic atmosphere. The dances are often accompanied by live music, featuring instruments like the fiddle, accordion, and bodhrán. Participants usually follow a caller who guides them through the steps, making it accessible for dancers of all skill levels. Ceilidh dances can include various formations, such as circles or lines, and often involve simple, repetitive movements that encourage interaction and fun among dancers.
