"I have learnt how to play a bit of the cello. In terms of making the correct sound, it needs more time, but it is not possible for me to dedicate three years to master it," Katrina said.
The actress explained that the film didn't require her to master the art of playing the cello, as it wasn't a biography of a cello player.
"My character happened to be a cello player in the film and I just had to get the right posture for it to look visually correct," she added.
The film, also starring Salman Khan, Zayed Khan and Anil Kapoor, didn't appeal to the audience.
