You either invest a ton of money into having people come together to play the music how you want it, or you buy/download a digital audio workstation with separate recorded instruments or VSTs. I'm not sure what you're asking specifically for, though. If you're talking about the action packed parts of each song, then the best instruments to go with are brass such as trumpets, French trumpets, trombones, and tubas with timpani playing behind it. I especially like the brass that hit lower notes because that gives me goosebumps. Taking up music classes would benefit you, I think, if you plan on making stuff like this. I like orchestral music, but I don't know if I could make one.
