Create a heavy-hitting deathcore metal track with a bone-chilling horror atmosphere. Set the song in a dark, sinister key such as D minor or E Phrygian, and infuse it with intense, relentless drums that drive the aggression. Incorporate haunting synth melodies to add an eerie element, while using both 808 and Moog bass to create a deep, rumbling foundation. Enhance the dark atmosphere with haunting choir vocals, eerie bell tones, and the metallic clang of steel drums. Add occasional bursts of energy with cymbal crashes and piercing whistle sounds for a truly chilling experience.
