Bollywood Dance began to change in the 70s. The Cabaret style of dance became more mainstream & was implemented in many movies. Later on Cabaret was replaced by Disco, which was a worldwide phenomenon at the time.
After experimenting with Classical, Semi Classical, Folk, Cabaret & Disco styles of dance, came an era which introduced Bollywood Free Style of dancing which was well represented by dancers like Govinda who developed their own signature style of dance.
Since the 1980's & the inception of MTV , Bollywood dancing has been heavily influenced by Western dance styles, and incorporates elements from the West. In many cases, the musical numbers are released as separate music videos, and the soundtracks are released prior to the film, in order to further advertise the upcoming feature films. In modern Bollywood films, the musical numbers are often based on the Hip-Hop style of dance as well as other variations of Hip-Hop dance.
Currently Bollywood Dance is still influenced by Western culture, perhaps even more so today than when it began. Elements include the use of frequent costume and location changes during dances, as well as the use of larger dance troupes. And the movements have become more bold & extroverted to capture the audience’s attention. The Evolution of Bollywood Dance is a process that is entirely Indian and yet cross-cultural at the same time.
