The “Monster Mash” is an experiment in Minecraft-based generative music: a dark mob-spawning pit lined with pressure plates and note blocks tuned to an F-sharp major scale. The random, almost Brownian movements of the monsters over the pressure plates produce dissonant note sequences.
The entire 50x50m complex is underwater in the middle of a blank Flatwater map. The viewing area is well-lit around the brick edges to prevent spawning, and 2m high to stop endermen from teleporting up into the safe area. Glass viewing floors provide views of the pit while blocking viewer-level mob spawning.
The pit is 10 meters deep to keep light from the safe area reaching the bottom; this facilitates mob spawning. A double layer of obsidian prevents enderman vandalism.
In the other pit, grass blocks and abundant lighting provide a venue for passive mobs — animals — to spawn. Note blocks here are set for percussion, so animals can play the drums.
An access tunnel runs between the pits, with a door to the animal pit, and iron bars for viewing the monster pit from the bottom. There is no access to the monster pit.
