Chord Detection Benchmark
MusicMind resolves chord movement into identifiable harmonic blocks. This benchmark shows chord density, uniqueness, confidence, and sophistication so a reader can see whether harmonic interpretation stays stable when the music becomes richer.
Signal definition
Dimension: Harmony
Focus: Chord confidence and uniqueness
Benchmark scope: Harmonic resolution and confidence at the chord level
Benchmark readout
The public readout for this benchmark.
This page documents the method; results are not yet published. Once measured, the readout will track the following dimensions so researchers, creators, and operators can inspect the same signal from multiple angles.
Methodology
How this benchmark is assembled.
Step 01
Chord blocks are estimated using offline chroma extraction and template correlation across the full track timeline.
Step 02
Average confidence aggregates per-block certainty across the detected harmonic sequence.
Step 03
Unique chord counts provide a quick measure of harmonic variety within the arrangement.
Step 04
Sophistication labels translate the detected harmonic field into readable tiers for research notes and reports.
