What it is, in plain English

Orchestra Kingdom is a teacher and audition judge for string players. A high school violinist preparing for All-State, a college bassist preparing for a regional orchestra audition, or a parent looking for a way to support their kid's practice records 30 seconds of any audition excerpt. The Audition Simulator, a calibrated AI panel, returns a verdict (Advance / Callback / Not Yet), an overall score 0-100, dimension scores across tone / intonation / rhythm / tempo / musicality, three strengths, three things to fix next, and a personalized practice drill.

The Teacher mode adds the teacher, in conversation, with voice, camera, and sheet music. The Oracle sends a personalized weekly practice plan every Sunday. The Simulator puts the student in front of three named AI panelists who deliberate live. The Forge runs peer-to-peer practice duels.

Free trial. First three Simulator takes are free, no signup, no card. Kingdom Pass is $19/mo.

Why it matters

Specialized for string players, not music broadly
The four orchestral string instruments (violin, viola, cello, double bass) get instrument-specific rubrics, repertoire calibration, and audition-context awareness. Generic music-AI tools treat them as variations of one thing. We don't.
Calibrated against real audition panels
The Audition Simulator's rubric matches what conservatory and all-state panels actually score on. We over-publish accuracy with confidence scores per take, so a less-sure take is labeled less-sure rather than confidently wrong.
Founder-led, not investor-led
No board, no exit pressure, no pivot risk. Roadmap is set by what string players actually need, not what makes a quarterly slide. The story is at /story; the manifesto is at /manifesto.
Real engineering velocity, not a wrapper
100+ product features shipped before launch. The kingdom is real because the underlying machinery is real, instrumented end-to-end, and built to keep compounding after public day.
