I've been listening to some songs from movies and tv shows and marveling on the effect that the song has on the imagery and vice versa. The creepiest opening sequence to a show that I've ever seen is a very good example of that kind of thing. Take away the music and it's not very scary, just weird. Listen to the song alone and it's actually quite formulaic and boringly repetitive. That got me thinking on what kinds of music could be used to create different moods, and also what I want to see soundtrack artists do differently. The thing that I most want to see is someone playing around with the full range of the instruments they are using. How often do you see someone playing a song on the piano using the far left and far right sides of the keyboard exclusively? The same goes for things like strings and choirs, especially choirs. Almost every time I hear a piece that's intended to bring a creepy, scary, or tense mood would benefit from having the bass part dropped by an octave, sometimes even two. (That's right, two! The choral pieces I've been familiar with always have the basses singing at the very top end of their range. It might be hard to get a large number of people who can pump out power at those notes, but it would be awesome!) What would the atmosphere be if you had an extremely high part coupled with an extremely low part and the two out of synch by half an octave or so? Would it sound bad, or would it sound wrong in a way to make the audience uneasy? That got me taking things to the logical extreme. Dropping the bass an octave is cooler, so then drop it two, then three, ect. Eventually you get to the area where a human can't hear it anymore. Have you ever stood in front of the subwoofers at a concert? You know how you can feel the vibration deep in your chest? Do filmmakers take advantage of that? What would happen if in a horror movie you had the standard scene of a character opening a door that could have something horrible behind it and the entire time it was silent, but the speakers were pumping a heartbeat through the speakers that was below the threshold for human hearing but still loud enough to feel? I think it would probably enhance the fear by a large amount. I've been told that some scientists believe that an effect like this is a possible reason why many people report spiritual experiences while listening to live organ performances. Does anyone know if filmmakers use effects like this already? I have a possible example in the first LOTR movie, where Frodo and the others fall off the cliff onto the roadway. There is a part right there with a very low rumbling where my tv speakers start spitting out static, but it's still in the audible range and not quite what I'm thinking. Are there any other sound tricks to manipulate the audience that you know of or can think of?
