for my horror game, i'm going to try to use two different music styles in normal gameplay. one for the daytime sequences, and one for the nighttime sequences when things get amped up.

the former will be something like bohren & der club of gore. extremely atmospheric jazz.

the latter will be something like drone metal, perhaps sunn o))) inspired.

i know silence is a good tool too, so the drone metal stuff at night will be a lot more akin to the bohren stuff but just with some distortion, if that makes sense.

there are a few different "floors" you'll go to, and each of those floors will have a different track that plays. each of those tracks will probably be like 10-15 minutes. then there will be some dedicated character and scene themes that are more upbeat, like the vocal songs in silent hill 3.

idk how close i'll get to these, but i do want to make sure the audio is really good. i think i might even make the voices during the night time segments crunchy, whereas they'll be very clear during the day. i want the switch between the two to be very contrasting. the themes need to have very strong melodies and some catchy vocals, preferably. it'll be interesting to see how close i get to this, with pretty much just myself to work with. i might be able to find a band to help out, but that's a little bit further into the future.
