Branderburg Concerto 4

Bach. First movement excerpt only. Baroque style with lots of counterpoint.

Mars (from "The Planets")

Holst's early 20th century orchestral piece. Classical music is just starting to delve into such things as dissonance and odd meters, so it's tempered, but there.

Voyager

Theme from Star Trek Voyager TV show. A modern fanfare.

Next Generation

Theme from Star Trek Next Generation TV show. A modern fanfare.

Deep Space 9

This has an "arabian march" flavor to it.

More typical "movie background" music, but more of a fanfare for an "action sequence".
