More rarely, the director will talk to the composer before shooting has started, so as to give more time to the composer or because the director needs to shoot scenes (namely song or dance scenes) according to the final score. Sometimes the director will have edited the film using "temp (temporary) music": already published pieces with a character that the director believes to fit specific scenes.
