What is Freedom of Expression for a Classical dancer? How innovative are contemporary choreographers?

With a vast tradition of classical dance such as Bharatnatyam it is not surprising that the movement towards the contemporary has emerged within the classical tradition. Unlike the West, India has no real defined modern dance, what we see are certain specimens of an extensions of a tradition, changes in thematic presentation or a heavy mixing and borrowing from other influence. No clear language of modern Indian dance has yet evolved, although contemporary dance has made great strides. It is difficult to understand the usage of the difference between 'Modern' and 'Contemporary'.
 What is defined as the modern Indian dance is actually a 'creative style or free-style where the theme is Indian for instance religion or the seasons since it is done in a language not bound by the grammar of any particular classical form.
Entering into the realm of liberated movement with abstract themes, there has been some brilliant choreography by noted dancers like Aditi Mangaldas, Akram Khan, Chandralekha from Chennai who have broken the shackles of conventional Bharatanatyam  as they refuse to see the body as being merely ornamental or decorative.
From being an art form that was so rigid and unalterable, today there is free choice of lyrics and music which can extend to songs in other languages there is scope for creativity, dancers have now yearning for new ideas, contents with modern day messages, dance forms themselves have shown remarkable resilience in  movement pattern. As times change, audience have developed a taste for a newer themes and nuances within the parameters of classical dance.
