Bollywood actors Abhishek Bachchan and Deepika Padukone launched the soundtrack of Hindi film, 'Khelein Hum Jee Jaan Sey' here on Wednesday.
The movie is a period film and is based on author Manini Chatterjee's book 'Do and Die', which describes the Chittagong Uprising of 1930.
Bollywood lyricist Javed Akhtar, who was also present on the occasion, said the essence of the songs lay in the language.
"Now these characters are Bengali. If I use pure Urdu with them, that will sound false. So, it should sound as if it has just been translated from Bengali. That effect should come in the language," said Akhtar.
The movie's composer, Sohail Sen, said that creating the soundtrack for the film was a different experience.
"Giving that Bengal's feel to it. And looking into what instruments are used there like Madhav and Iktara (single-string) are used there a lot. Compiling the sound from those instruments, we designed the songs," said Sen.
"In period movies, like the one I did with Ashutosh Gowariker, the music was contemporary; but this one was a different experience. I wasn't scared but had lots of fun creating and exploring it," he added.
Director Ashutosh Gowariker said that the music of the film represents various emotions of revolution.
"The songs of the movie represent revolution and its different emotions whether it be patriotism or friendship or about the courage of the children. We wanted to convey these emotions. So far our promotions are focused on this theme only," he said.
The movie is set to release worldwide on December 3. (ANI)
