Dance Genre

The dance genres are divided into Old School styles, which are dance styles from the 1970s to 1990s, and New School styles, which are dance styles that have appeared since the 1990s. We asked the experts on street dances to set the dance genres.

Dancer

To cover choreographic variations within dance genres, we had 35 professional dancers (20 male and 15 female) participate in video recordings in a professional studio. At least 3 dancers performed each genre. All dancers had more than 5 years of dance experience. All videos were recorded in full color, although dancers mainly wore monotone clothing when dancing. Please see Dancer Info for more detailed information on the dancers.

Camera

We fixed all camera positions except for the moving camera. The height of the cameras was 180 cm above the floor except for camera C09, which was 40 cm above the floor. The location of the front-facing camera was carefully designed to capture the full body of the dancers, and the other cameras were located to capture as much of the dancers’ body as possible except for group dance.

Choreography

Basic Dance videos contain the commonly shared basic dance motions. The list of those dance motions are available here.

Music

This database includes 60 musical pieces over 10 dance genres. Each piece is available for download at Get Only Music Data.

The tempi of the 6 pieces (one piece for one genre, except for House) were set to 80, 90, 100, 110, 120, and 130 beats per minute (BPM). The tempi for the six pieces of House were set to 110, 115, 120, 125, 130, and 135 BPM.
