#4563 Knowledge Graph of Musical Chords #4563 Describe a musical chord knowledge graph A musical chord knowledge graph is a structured, multi-dimensional semantic network that maps the relationships between chords, their constituent notes, acoustic properties, and functional roles within harmonic theory. Instead of treating chords as isolated text labels or static MIDI arrays, a knowledge graph models harmony as an interconnected web of nodes and edges, allowing a system to traverse musical concepts fluidly—such as moving from a specific pitch collection to its functional role in a jazz progression. Here is a breakdown of how such a graph is architected, from its core ontology to its practical applications. 1. Core Ontological Nodes (Vertices) To capture the full depth of harmonic theory, the graph requires a multi-layered node strategy: Pitch Class Nodes: The fundamental building blocks ( $C, C\sharp/D\flat, D, \dots$ ). These are abstract entities independent of octave. Pitch N...
