| # Rescored Documentation | |
| ## Project Vision | |
| Rescored is an AI-powered music transcription and notation editor that converts YouTube videos into editable sheet music. Musicians can paste a URL, get professional-quality notation, edit it, and export in standard formats. | |
| ## What This Documentation Covers | |
| This documentation serves as the technical blueprint for implementing Rescored. It focuses on: | |
| - **Architecture & Design**: System structure, technology choices, and rationale | |
| - **Backend Processing**: Audio extraction, ML transcription pipeline, API design | |
| - **Frontend Interface**: Sheet music rendering, interactive editing, playback | |
| - **Integration**: How components communicate and data flows through the system | |
| - **Implementation Roadmap**: MVP scope and future feature phases | |

| ## Key Principles | |
| 1. **MVP First**: Focus on single-instrument (piano) transcription before multi-instrument | |
| 2. **Quality Over Speed**: Prioritize transcription accuracy over processing time | |
| 3. **Editable Output**: Transcription won't be perfect—editor is critical for fixing errors | |
| 4. **Standard Formats**: Use MusicXML/MIDI for maximum compatibility | |
| 5. **Async Everything**: Audio processing is slow—use queues and WebSocket updates | |
| ## Quick Reference | |
| **Primary Use Case**: YouTube URL → Transcribed piano sheet music → Edit → Export | |
| **Tech Stack Summary**: | |
| - Frontend: React + VexFlow + Tone.js | |
| - Backend: Python/FastAPI + Celery + Redis | |
| - ML: Demucs (source separation) + basic-pitch (transcription) | |
| - Formats: MusicXML (primary), MIDI (export) | |
| **MVP Timeline**: Focused on getting piano transcription working end-to-end with basic editing | |
