Modern dance. The form of dance style known as modern dance is an artistic dance form that allows free movement based on choreography that seeks to provide the audience with a subject and theme. Modern dance performers created this free form style to allow older dancers to continue to dance long after their ballet dance careers ended.
1 Natya Shastra classifies this type of dance form as margi, or the soul-liberating dance, unlike the desi (purely entertaining) forms. 2  Dances performed in royal courts to the accompaniment of classical music were called Carnatakam.3  This was an intellectual art form.ven though the art of Natya includes nritta, or dance proper, Natya has never been limited to dancing and includes singing, abhinaya (mime acting). These features are common to all the Indian classical styles. In the margi form Nritta is composed of karanas, while the desi nritta consists mainly of adavus.
