I was curious how one can take a melody/theme villainous/darker/evil sounding. I love the idea of dark reprises and was curious how to go about this. I write electronic music and remix in a similar style (i'm quite eccentric). I have a few themes I want to do this with and would like pointers.
I know things like occasional tritones, minor keys, diminished chords, and accidentals are important but what else>?
One of the pieces I want to do a villainous remix of (not having much luck due to the upbeat and repetitive nature of the piece).
