Where it works
Halloween content, haunted house tours, light horror games.
Building it in practice
Spooky sits between fun and fear. Harpsichord, organ, theremin-like synths, creaky textures and a waltz rhythm suggest haunted houses without real horror. Diminished chords and chromatic melodies add unease. For children's content, keep the tempo bouncy and the instruments playful; for older audiences, add lower drones and distant choirs. A short spooky sting at the start of a video sets the tone without overwhelming the rest of it.
