The legs must move in time of the rhythm, and in the opposite direction of the partner. Dancers continue around in a circle, keeping in time with the beat of the drum. There is often a decorated pole or a vase of flowers used to mark the center of the circle.
Because of its popularity, Lam Vong is considered as Laos national dance. Everyone knows how to do Lam Vong dance whoever they are children, solders, farmers, etc. There are many variations of the dance in each religion, but the spirit remains the same.
Lam Vong is carried out in special occasions such as: guest welcoming, wedding by the groom and the bride, celebrating New Year, at parties, festivals, etc. In the parties, people don’t usually wear Laotian traditional costume, therefore, they can do traditional dance without it. But when women take part in formal event such as a wedding, they have to wear the “sinh” as compulsory. In contraction, men don’t have to wear Laotian traditional costume; the only moment when they wear it is in their wedding.
