What components make military music especially rousing?
If someone were going to compose a piece of military music to especially rousing, what components would they be looking to emphasize? Like is there a certain key or time that military music is often played in that makes it especially rousing? What components of the brass section would the composer emphasize? I feel like the trombone and snare drums are instruments often emphasized; are there any others? Basically, are there any heuristics a composer might use if commissioned by some government to make young men willingly go into battle?
