The ancient Indian treatise on performing arts, the Natyashastra, attributes specific terms to different styles of dance based on their characteristics.
The term used for a vigorous, dynamic, and often masculine style of dancing is Tandava. This style is associated with energy and power.
Conversely, the term for a soft, delicate, and graceful style of dancing is Lasya. This style emphasizes beauty, tenderness, and charm.
