Chord Detection Benchmark Research Brief
Chord detection is the gateway between tonal identity and harmonic narrative. It becomes valuable when confidence, variety, and function stay legible as the song gets denser.
Program logic
Benchmark: Chord Detection Benchmark
Dimension: Harmony
Signal: Chord confidence and uniqueness
Audience: Readers who need the benchmark to behave like a public research artifact rather than a product feature.
Primary question
How clearly does the system resolve harmonic motion once the arrangement becomes musically rich?
Program frame
Place the benchmark inside the citation chain, the corpus logic, and the broader observatory system.
Corpus slice
Harmonic resolution and confidence at the chord level
Research Brief
What the research layer clarifies.
Research move 01
This benchmark supports public claims about harmonic richness, voice leading, and structural differentiation.
Research move 02
Detection confidence should be read with sophistication, not against it. Richer harmony often carries lower certainty and higher interpretive value.
Research move 03
A chord benchmark is only useful once its results are measured against labelled songs; until then, read it as a method.
Method cues
How this benchmark earns trust.
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.
