Harmonic Analysis Annotation Service for Sheet Music

A boutique annotation service where trained music theorists hand-analyze scores that musicians submit, marking harmonic progressions, voice-leading, and unusual concepts (Picardy thirds, augmented sixth chords, modal mixture, etc.) directly on the score with explanatory notes. Delivered as marked-up PDFs or interactive score files within 5-7 business days. Scales through a network of vetted freelance theorists.

SERVICE

25 weeks • 70% confidence

Value Proposition

Removes the guesswork and academic gatekeeping—musicians get *their specific piece* analyzed by a real expert, not a generic video. Faster and cheaper than hiring a private theory tutor ($30-60/score vs. $60-150/hour tutoring). Tangible, reusable artifact they can reference forever and share with students/ensemble members.

Target Audience

Music students (undergrad/grad), independent composers, chamber musicians, music teachers preparing lesson materials, conservatory faculty supplementing their analysis courses

Key Features

  • Custom harmonic annotation directly on submitted scores (PDF, MuseXML, or scanned sheet music)
  • Explanatory footnotes for every non-diatonic harmony, voice-leading quirk, or structural anomaly
  • Tiered analysis depth: 'Overview' (main harmonic spine), 'Deep Dive' (every chord, voice-leading, historical context)
  • And more, with full implementation detail...

Tech Stack

MuseXML editor API (Flat.io or Noteflight) for digital annotation PDF annotation tools (Adobe Acrobat, GoodNotes for iPad) Stripe for payments Simple web app (React/Node or Django) for job queue and user dashboard

Original Problem

Musicians struggle to understand and analyze complex harmonic theory in classical compositions

Music students, composers, and musicians frequently encounter obscure harmonic concepts (like Picardy thirds and their variations) in classical works but lack accessible resources to understand them. Current music theory resources are either too academic/dense or too basic, leaving practitioners stuck when analyzing real compositions and unable to confidently explain what they're hearing.
