group of children in school uniforms standing and playing musical instruments on a sandy surface. There are around 20 children, mostly wearing light blue short-sleeved shirts and either dark blue or gray skirts or shorts. Some are holding and playing saxophones, while others appear to be playing other wind instruments. An adult male in a white shirt and black pants stands among them, possibly instructing or directing the children. The setting appears to be an outdoor schoolyard, enclosed by a low concrete wall. In the background, there are buildings, including one with a dark roof. The video is shot from a slightly elevated perspective, looking down onto the group of children. A dark horizontal bar is visible in the foreground, partially obscuring the view. Some children are walking, moving in and out of the group.
