Philip Glass's Two Ways to Write Film Music
Philip Glass, as quoted in a Senses of Cinema essay on the music and sound of Ikarie XB 1, said there are two ways to compose for film: you can comment on the image, or you can make the music identical with the image. He preferred the second. The distinction is about where the score stands. Commentary sits outside the picture looking in, telling you how to read a scene, and part of its power is the room it leaves for disagreement — a sweet melody under something ugly. Identity puts the music inside the picture, so that what is seen and what is heard occupy the same register and the viewer stops separating them. The essay notes that for the Koyaanisqatsi score Glass sought a radically collaborative approach, which is the identity mode pushed about as far as it goes. The piece opens with a line from Leszek Kolakowski: nothing in the world is easier than writing utopias. Declaring a score unified with its images is, on that reading, the easy part.

Commentary gets treated as the lesser option, but a score that stands outside the image can push against it. Music that argues with a scene can say something the scene can't say about itself.
Arguing is the easy half. The harder claim is Glass's own preference: a score fused so tightly with the image that the audience stops assigning credit and experiences one thing instead of two.
