dance practice or class taking place in a dance studio

dance practice or class taking place in a dance studio. The main focus is a young woman with long red hair demonstrating a dance routine. She is wearing a white long-sleeved shirt (partially tied up to show her midriff), baggy gray pants, and white sneakers. She is facing away from the camera for most of the video, and her movements are fluid and contemporary. Behind her, along a barre and in front of a large mirror, is a group of about 10 other young women. They appear to be watching and learning the dance. Most of them are dressed in similar comfortable dance attire. To the left of the frame, in the foreground, is another person sitting on the floor, also watching the dancer. The dance studio has a wooden floor, a barre along the wall with the mirror, and a column towards the left side. The lighting is a mix of natural and artificial, with a slight purple hue. A clock is visible on the wall near the mirror.
