I've always believed that a great score doesn't compete with the visuals... it completes them.
A scene can be beautifully shot and brilliantly acted, but the right music gives it emotional direction. It tells the audience how long to hold onto a moment, when to breathe, when to hope, and when to fear. Often without them realizing why.
As a composer, my goal is never to write "beautiful music." My goal is to write music that belongs to the story. Sometimes that means a sweeping orchestral theme. Sometimes it means a single sustained note... or complete silence.
The best compliment a film score can receive is when the audience leaves the theater remembering how they felt, even if they can't recall a single cue.
For the directors and producers here:
At what stage do you usually bring your composer into the project? I find that involving music early in the storytelling process often opens up creative possibilities that aren't possible when scoring only after picture lock.
I'd love to hear your experiences.
