This brass episode is short and epic, in a minor key to create a sense of tension and forbidding. The harmonies create something you’d hear in an intense John Williams score like Star Wars of Indiana Jones. It is a very iconic and idiomatic sound to that heard throughout the past few decades of film music. It’s very easy to chop the phrase up and use snippets of each section (or lengthen it) to get it to the desired length. Hope you enjoy!
