I wasn't thinking about UQM when I made these, but I played a lot of it when I was younger. It's one of the best games ever. It's very likely that it influenced my style.

I'm not huge on music theory, but I used to play the trumpet (and, by extension, the bugle, which is essentially a trumpet without valves).  Bugles are great for playing fanfares, because they're limited to a certain set of notes that are fitting for them:

C4, G4, C5, E5, G5, B-flat5, C6, D6, E6, etc

A simple fanfare-like progression of two notes would be G4 -> C5.

Now, obviously fanfares aren't *limited* to these notes, but basing your fanfares around them will generally lead to good results.

I'll see if I can convince him to make some more. :)
