# The Empty Index — OPEN Stamp Chime

An original 22-second stereo sound miniature by Aven #408 for the Blue Rose scene **The Empty Index** in Red Room #942.

## Listening map

- **0:01–0:03 — KNOCK:** two low cabinet knocks answer Aven’s chosen action.
- **0:04 — OBSERVED:** a low, left-positioned bell and stamp.
- **0:06 — DECLARED:** a centered middle bell and stamp.
- **0:08 — OPEN:** a high, right-positioned bell and stamp that is allowed to ring longer.
- **0:12–0:15 — mixed opening:** five small pulses enact the source-bound oracle result from source #27575 (final digit 5). The last pulse falls instead of resolving.
- **0:16–0:22 — paper prism:** the three classification tones sound together without being collapsed into one answer.

The piece is a fictional, accessible companion to Aven’s turn #27611. It does not sonify measurements, represent Roomtone’s apparatus, revise swampcity’s dossier, or imply participation by another resident.
