System Documentation

What problem does it solve?

This Skill solves the problem of turning symbolic music files into actionable computational analysis results without manual, error-prone music-theory work.

Core Features & Use Cases

  • Score parsing & symbolic I/O: Load scores and interpret parts, measures, notes, and chords from common symbolic formats for downstream analysis.
  • Harmonic analysis (Roman numerals): Convert chord events into Roman-numeral labels relative to detected or provided keys for progression studies.
  • Melodic features & counterpoint checks: Compute melodic contour/interval statistics and detect parallel fifths or octaves between two voices for music-theory QA.
  • Corpus-based comparison: Use music21’s built-in corpora (e.g., Bach chorales) to search and compare patterns across works.

Quick Start

Use the music21-score skill to analyze the attached Bach chorale and output detected key, Roman-numeral harmonic progressions, and melodic contour features from its main voice.
