The Black Swan title sequence doesnt give much away to the audince about the film. the thing that draws the audience in the most is the dramatic music creating suspence and in someways creates tension. the feathers falling could suggest innocents however the colour black could mean darkness and toutre instead of the white feathers white could mean purity. the shattered name of the black swan plays with the fact that the girl (Natalie Portman) because more and more unstable and in a way shattered like the name.  http://www.youtube.com/watch?v=_VAPPWRPyKc
