Horror trailers run on tension and release: a long quiet stretch, one sharp hit, then dread. Below are 10 Suno templates covering the main horror sub-styles — each with explicit drone, hit, and drop instructions.
What a high-quality prompt should contain
Suno horror trailer prompts need 6 layers:
- Horror sub-style:
psychological thriller/slasher/cosmic horror/J-horror/body horror - BPM: 40–90 — slower for dread, faster only for slasher / jump-scare drops
- Key: minor (Cm / Am / Dm / Em / Bm) almost always; major (C) only for the cursed-childhood / lullaby twist
- Sound design: drones, dissonant strings, music-box, reversed cymbals, sub-pulse, screech risers
- Vocal role:
no vocalsorghostly wordless choir/child hummingonly when called for - Production:
modern horror trailer production/analog horror sound design

- Just
scary music— Suno gives generic minor-key - No hit / screech timing — tension never releases
- Lyrics on the choir — words break dread, use
wordlessorhumming - BPM too fast (above 100) — sounds like action, not horror
- Too many drones layered at once — turns into noise, not tension

FAQ
Q: Will Suno actually generate scary audio or filter it?
A: Suno usually allows horror sound design. Avoid graphic violence words in the prompt — describe music and atmosphere, not gore.
Q: How do I get a real jump-scare hit?
A: Use template 10 with dead-silent intro and massive orchestral impact at 0:10. Generate 4 takes — silence quality varies.
Q: My horror cue sounds like a thriller, not horror — fix?
A: Drop BPM below 70, add dissonant cluster and reversed risers, remove any major-key uplift words.
Q: Can I layer child voices?
A: Use child humming not lyrics. Suno renders humming better than spoken-word-style child voices.
Q: Horror cue length?
A: 30–60 seconds for trailer cues; a single 60–90 second build for a teaser. Suno’s 2-minute output is plenty.
