A group of children stands outdoors, some holding drums. One child is in a green shirt and black pants. Several other children wear blue and yellow school uniforms. A child in a red shirt is partially visible. There are drums of various sizes. A building and a large tree are in the background. The ground is dirt and grass. Some of the children are talking, seemingly coordinating or practicing. The video appears to be shot on a cloudy day.
