John Williams on his process of film composing

Williams: Melodies or melodic identification are, for me, the hardest things to do, and I spend a lot of time on those melodies that will sound very simple or inevitable when they’re heard. In a case like this, it’s weeks of tinkering around with various approaches and different ideas and trying to manipulate one or the other to make it feel like it lives or wants to belong in the film in a very natural way. It’s not easy for me, and I spend more time doing that than orchestrating or developing or doing contrapuntal workouts of the material — once I have the material, all those other things are relatively easy. Beyond that, it’s always hard to say. If we talk about the genesis of these things, a lot of it has to do with the way you feel and how you respond to the material. – excerpt from Hollywood Reporter, January 10, 2006 interview with Jeff Bond
