This is true even where the whole point of the music entrance or end is to be very dramatic. For example, if the music starts on a startling action or picture CUT in a very loud and dramatic fashion, when done right the audience won’t notice that the music suddenly came in strong, they’ll just be startled by what’s happening on the screen. Same goes for creating a massive build into a climactic moment. If done right the audience shouldn’t notice that the music drops off suddenly, they should just feel the enormity and the shock of the moment. If you’re paying attention to the music, it’s probably not quite right yet.
