Having had an interest in horror film soundtracks very recently I've listened to several extracts and found that (at least when concerning the film's main theme) with a lot of the more notably scary horror films, either the music was a little too lush and beautiful-sounding at times (thus for me not appearing to convey the sense of horror and despair that the more 'hardcore' horror films are reputed for), or it did quite the opposite by making use of all sorts of gritty electroaccoustic effects and constant dissonances to the point that it didn't feel like tat good a soundtrack on its own (it was creepy, but alot of it wasn't neccessarily music). Of course there were a couple which just revolved around really really basic themes and remained in the same key, just orchestrating what was already very debatably an actual melody a little more each time it repeated in a vain attempt to heighten the drama. It seems a complecated conundrum the horror film soundtrack - either it's not horrible enough to bond with the film, not musical enough to work as a soundtrack on its own, or written for a film too bloody for any respectable composer to beable to endure (imagine having to watch horrific clips over and over again in order to develop and sync the music to them). Looking into some of the fims which, although equally scary, are more focused on heightening the terror and telling a good story as apposed to going for nothing but pure unadulterated shock value, I found that the soundtracks generally seemed better suited on the whole. An example being the theme to the initial three Final Destination films by the late Shirley Walker - I think the initial use of tritones and minor 6ths while never stopping on the tonic G for too long creates a really tense and disturbing feel, which for me kind of characterises the basic idea of the films themselves. It then becomes slightly more tonal by changing keys a few times and altering the intervals a little, which I personally think makes it good as an actual piece of music - it's actually telling you something.
Sorry for the loooong post and the fact that I've abruptly stormed the forum in order to thrust it upon everyone without so much as an introductory post. I'm just very intrigued as to what other people think about these views. I'm honestly very happy to be here and can't believe I've taken so long to join a forum with it's own section dedicated to music.
