A Goa hotel room is serving as a studio for singer-composer Sohail Sen who is creating music for Ashutosh Gowariker's upcoming period film "Khelein Hum Jee Jaan Sey".

"I made most of the music for the movie in my hotel room in Goa, " Sen told over phone from Mumbai. The movie will be released Dec 3.

"I used to go to the sets, see the actors work and then come back to my hotel room. I had my team and a small set-up there itself, " he added.

"Khelein..." is based on Manini Chatterjee's book "Do And Die" on the Chittagong uprising of the 1930s. It features Abhishek Bachchan and Deepika Padukone in key roles.

Sen, who earlier composed music for Gowariker's "What's Your Rashee?", said it was quite a daunting task to make melodies for the period thriller.

"Composing for 'Khelein...' was very different from composing for 'What's Your Raashee?' or even the other movies I've done in the past. This film is set in undivided Bengal of the early 1930s; so music had to be composed accordingly, " said Sen.

"Besides, one of the songs had to be picturised on Abhishek and Deepika, who are shown to have a huge age difference in the film. I had to do justice to the film from every point of view, " he added.

The song in question is "Sapne salone".

"This is the only romantic song in the film and it is closest to my heart since it took a lot of effort and thought on my part, " he said.

For the entire album, Sen has used "an amalgamation of instruments, genres and sub-genres of Bengali folk music".

The album, which has five originals, is packed with high energy and soft soothing melodious songs but is high on patriotic sentiment to capture the essence of the uprising.

The 26-year-old was particularly comfortable working with Gowariker and felt he knew the director's taste inside out.

"Ashutosh is like family now; since I've worked with him before, I know the tunes he wants and can give him just that, " Sen said.

After working on "Khelein...", the composer is now looking forward to weaving tunes for Imran Khan-Katrina Kaif-starrer "Mere Brother Ki Dulhan".

"I'm blessed. 'Mere Brother Ki Dulhan' came as a good opportunity for me as it would be an out and out commercial movie after a period film, " Sen said.
