THIRI is the harmony layer under the platforms shaping music AI —
deterministic chord intelligence, served as infrastructure. Every page below
is a working pitch: playable demos, real code, real renders, built
against each platform as it actually ships.
Integration studies require a work email — one signup unlocks every dossier.
Same model, same prompt, same seed — the only variable is the harmony. Switch renders mid-bar and hear the changes move.
PLAYABLE 12-BAR CHORD RAILRun The Changes turns charts into practice levels — guide tones, étude reports, assignment links. Built for the gap where nine in ten quit.
LIVE GAME, PLAYABLE ON-PAGEAn LLM in the session still can't reason about harmony. thiri-mcp is the theory layer that makes the multiplayer-AI promise concrete.
AGENT FLOW, LIVE THROUGH STEP 2The largest under-digitized instrument market meets harmony that follows breath and intent — live, on the Aerophone.
BUILDING LIVE IN MONTREAL, AUG 22–23An app whose promise is removing barriers in learning and performance needs musical intelligence that's correct every time. It's live today.
API + PRACTICE ENGINE, IN PRODUCTIONA looper that loops harmony, not just audio — the chord bed holds, evolves, and re-voices itself on the pedalboard. Max/MSP inside a looper pedal.
BUILDING FOR THE HARDWARE TRACK, MONTREALAnalog and FM synthesis, talked into existence — one parameter at a time, rendered and measured, with the generated orchestra yours to download and run.
RENDERED AUDIO + DOWNLOADABLE .CSDDeterministic chord intelligence — analysis, voicings, voice-leading, reharmonization — live as a REST API and a hosted MCP server for agents. Computed, not guessed.
If your platform needs harmony it can trust — a chord track, a practice loop, an agent that knows theory — the first step is smaller than a meeting.
