Film music can convey many emotions and settings, sadness and happiness, a rural countryside or a dark forest. Anything. Hope this helps in some way :)
tensions rises, and some sort of crisis occurs and reaches its climax (development). Then the crisis is resolved (recapitulation). Maybe there's a twist at the end (coda). The mains “scenes” within sonata-allegro form are 1) exposition, 2) development, and 3) recapitulation.
