Organ music — heavy stops, deep pedals, long sustains. Pipe organ carries everything. The reed stops cut through the texture for menace. The flue pipes hold the chord swells for prayer and chorale. Pedal notes rumble below at 30–60 Hz, low enough that you feel them more than hear them. Some pieces sit on a Bach-style chorale at 60 BPM. Others build through a toccata pattern, fast and dissonant.
Horror filmmakers use the dissonant drones under crypt and cathedral shots. Halloween creators sync chorale swells to slow-motion zooms on stained glass. Period-drama editors bed processional organ under weddings and funerals from another century. Wedding videographers pick the lighter cuts for traditional church ceremonies. Also works for paranormal podcasts, video-game cathedral levels, and gothic Twitch streams. See also gothic or horror.
