When we experience a film, we consciously prime ourselves for illusion. Putting aside will and intellect, we make way for it in our imagination. The sequence of pictures plays directly on our feelings. Music works in the same fashion; I would say that there is no art form that has so much in common with film as music. Both affect our emotions directly, not via the intellect. And film is mainly rhythm; it is inhalation and exhalation in continuous sequence.
