John Williams, how you do it?

How does John Williams repeatedly to compose such brilliant music?
Again John Williams wrote an Oscar worthy soundtrack. From the first minute to the end draws this soundtrack from new ideas, ingenious variations and a great structure. From a fanciful, mysterious main theme, through loving melodies (eg Diagon Alley) to usual-genius fanfare at quidditch match offers this soundtrack variety, excitement and music enjoyment on the highest level. 5 Stars!
