Like writers, composers labor over single stanzas through dozens of iterations until the notation on the page reflects the symphony in their head. When this person is commissioned, he or she may be given some basis of inspiration to draw from ahead of time—a script, film or video footage, or storyboards—but often the composer is the last on board and works to a finished, edited film. From this material and collaboration with the director and producer, the composer cultivates a sense of time, place, action, and emotion, which must be reflected and translated through the score.
