Orchestration Voice-Leading Decision Trees & Reference Cards

A physical + digital hybrid product: laminated decision-tree flowcharts (one per common harmonic situation: root position triads, first inversions, seventh chords, extensions, chromatic alterations) that orchestrators pin above their desk or keep in a score folder. Each card shows the specific doubling rules, voice-leading constraints, and instrument-pairing recommendations for that harmonic context. Digital companion: searchable PDF index and a printed workbook with annotated orchestral excerpts showing the rules in action.

Value Proposition

Eliminates the need to flip between five textbooks or scroll through fragmented forum threads mid-composition. Rules are visualized as decision trees (not prose), so the answer is found in 15 seconds, not 15 minutes. Physical cards mean zero context-switching friction—no app, no login, no distraction. Orchestrators can see the rule, the exception, AND real professional examples on one card.

Target Audience

Orchestration students (conservatory/university level), freelance film/game composers, and professional orchestrators doing detailed arranging work who need fast, reliable reference during composition sessions

Key Features

8–12 laminated decision-tree cards (triads, inversions, sevenths, ninths, alterations, chromatic voice-leading, instrument-specific constraints, jazz extensions)
Each card includes: rule, exceptions, forbidden doublings, recommended instrument pairings, and 2–3 annotated score excerpts (Brahms, Ravel, John Williams, etc.)
Printed 80-page workbook: 20 real orchestral passages with voice-leading analysis and doubling decisions explained
And more, with full implementation detail...

Tech Stack

Original Problem

Orchestrators struggle to understand and apply complex voice-leading rules for note doubling in inversions and extensions

Music composers and orchestration students lack clear, practical guidance on when and how to double notes in chord inversions and extended harmonies, leading to confusion about voice-leading rules and poor orchestration decisions. Existing resources are fragmented across textbooks and forums, making it difficult to find specific answers to nuanced harmonic situations. This creates frustration when trying to write idiomatic, professional-sounding orchestrations.
