group of about 10 people practicing dance moves in a brightly lit dance studio. The studio has a gray floor, white walls, and an air conditioner mounted high on one wall. There are also a few windows. Most of the participants are adults, though a couple appear to be younger teenagers. The dancers are dressed casually in athletic wear, and all are wearing sneakers. They are spaced across the room as they practice a routine to music that plays in the background. The dance instructor, a bearded man in a green shirt and shorts, occasionally adjusts the participants' positions or demonstrates the moves.
