Where musicians
are measured.
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.

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.
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
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.

SUB-BEAT ANALYSIS · PHRASE-LEVEL · DRIFT DETECTION
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.

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.

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
