And it's amazing how much we know that we don't realize we know. Like music - I'm not a trained musician, but when you get into it, you discover you really do have an understanding of the form and have incredibly strong feelings about how music should be made.
Music deals with abstractions and, like film, it involves time.
It has many different movements, it has much contrast. And through music you learn that, in order to get a particular beautiful feeling, you have to have started far back, arranging certain things in a certain way. Well, music gives you an indication of the mood, again, and if you lock out and find things out upfront they can help you tremendously. If the music reinforces it or if you have to start again. And that's the power of music and the potential power of cinema.
