Decode Rocky.
For Marrickville Festival, Chloe's giant crochet Rocky will sit behind Qwerty's glass door. Passersby will have a small interface outside and try to communicate with him.
The question
You do not need to solve the whole language. One convincing bridge between the production language and the finished-film sounds would already be useful.
Keep four evidence buckets separate.
Peterson language design
David and Jessie Peterson created a structured musical language system during production. Their working documents and test audio are public.
Rocky's performed voice
The film sound-design team created the finished voice and says it maintained a database of about 250 words/concepts used consistently across the movie.
Reconstructions
Useful clues, but some fan projects mix close listening with invented vocabulary. Don't call a fan mapping canonical unless we can trace it.
Our implementation
We can simplify or invent whatever the installation needs, provided we clearly label it as our version rather than official Eridian.
Rocky isn't just singing one melody.
The production system uses three principal simultaneous vocal lines, each drawing from a restricted seven-note set. Two lines mainly carry lexical information; a third helps mark word and grammatical structure.
Relative pitch matters
The Petersons designed it so humans would not necessarily need perfect pitch. Interval movement and relationships between notes can carry the useful pattern.
Delivery can add tone
Staccato, tremolo, pitch distortion and extra vocal channels were proposed as ways to add precision, hesitation, emotion or other pragmatic information.
Your advantage
Listen for interval shape, layered voices, rhythm, segmentation and recurrence before worrying about naming every absolute pitch.

Useful concepts to hunt for
| Concept | Why useful | Your note |
|---|---|---|
| hello | Ideal first-contact word | |
| yes | Easy response / confirmation | |
| understand | Perfect game mechanic | |
| you / me | Basic conversational structure | |
| help | Already appears in test sentences | |
| question | Could distinguish prompts | |
| one / two / six | Numbers may recur cleanly |
Did the Peterson patterns survive into the finished Rocky?
The finished movie's sound team says Rocky uses about 250 words and concepts. Their assistant maintained a database so recurring words could remain consistent across the film.
That does not automatically mean every final-film sound is identical to the Peterson development notation. The finished voice passed through another sound-design process.
scripted words/concepts in the film team's internal language database.
Production notation → finished film.
- Read the Rocky Test Sentences first. They're short and deliberately repetitive.
- Listen to several Peterson production audio tests so the three-line system is in your ear.
- Pick one or two clean Rocky exchanges in the finished film where the meaning is obvious from context.
- Compare musical contour: intervals, recurring voices, rhythm, chord shape and word boundaries.
- Don't worry if the absolute key differs. Relative movement may matter more.
- Record what matches, partly matches, or looks completely redesigned.

Short + repeated + contextually clear beats impressive-but-impossible.

Notes / patterns / suspicions
A tiny first-contact language for the door.
Festival
A passerby learns enough Rocky to make contact through a handmade control panel outside the locked glass door.
Music
Listening, interval relationships, memory and pattern recognition become part of the interaction without turning into a worksheet.
Build
Crochet + sound + electronics + code + language + interaction design. Very Qwerty. Potential Coolest Projects legs if it develops far enough.
Don't optimise yet
For now, the interesting problem isn't “how do we build the buttons?” It is: what can we honestly learn from Rocky's language, and what would a human need in order to answer him?
