Where musicians
are measured.

Now in private beta · Anno MMXXV

A performance intelligence platform that scores your playing with the precision of a master’s ear — pitch to the cent, timing to the millisecond, expression to the phrase.

MANIFESTO — I

The instrument
is not the art.

Music has always been measured — by teachers, by audiences, by history. Wintergarden makes that measurement precise, verifiable, and financially meaningful.

We are not a streaming service. We are not a practice application. We are a conservatory rendered in code — a quiet room where the only thing that matters is the sound you make now.

THE FEEDBACK ARCHITECTURE

Four stages. One score.

01/CAPTURE

Acoustic Signal Isolation

Every note you play is captured at the waveform level before any processing occurs. Wintergarden isolates the fundamental frequency from harmonic content, separating the performed pitch from resonance, room, and instrument body noise.

REAL-TIME · WAVEFORM · FUNDAMENTAL ISOLATION

02/ANALYSE

Temporal Mapping

Rhythmic intent is reconstructed from the performed event stream and compared against the notated score at the sub-beat level. Variance is mapped phrase by phrase, revealing the difference between expressive timing and technical drift.

03/INTERPRET

Expression Recognition

Dynamic contour, articulation shape, and phrasing arc are modelled across the full musical gesture — not the individual note. The system distinguishes a deliberate diminuendo from an unintended fade, and a stylistic rubato from a loss of tempo.

04/SCORE

Composite Performance Rating

Pitch accuracy, rhythmic precision, and expressive fidelity are weighted and collapsed into a single composite score — calibrated against a corpus of professional recordings and adjustable by genre, period, and pedagogy. Verifiable. Reproducible. Meaningful.

Wallet mechanics

USDC · weekly · on-chain

Where the work goes.

Each session produces three things that belong to you: a payment, a permanent record, and a line in your library. Here is what each one looks like.

01

Weekly Rewards

Every week, a shared pool of USDC is divided among the top-ranked performers. Your rank in the active cohort determines your share. Payments arrive directly in your connected wallet — automatically, on a fixed schedule.

  • Pool size$50,000 USDC · Week 18
  • DistributionEvery Sunday, 00:00 UTC
  • QualificationTop 500 performers by rank

02

Merit Badges

Each qualifying session earns a permanent badge — a verifiable record of what you played, how you scored, and when. Badges are yours forever, inscribed on-chain, and cannot be altered, lost, or transferred. They are the transcript of your craft.

  • FormOn-chain merit token (non-transferable)
  • UnlocksScore ≥ 75 on verified repertoire
  • VerifiablePublic record · always yours

03

Your Library

Every session is archived. Every score is kept. Your library is a timeline of your playing — every performance, every piece, every evolution of your score. Searchable, filterable, and yours to review at any time.

  • ArchivedUnlimited sessions, permanent storage
  • TrackedScore progression by piece and skill
  • PrivateYours alone — never sold, never shared
