Key Detection Benchmark Creator Guide
Key detection only matters if tonal certainty, mode, and ambiguity explain how the song feels and how the harmony should be communicated downstream.
Program logic
Benchmark: Key Detection Benchmark
Dimension: Harmony
Signal: Tonal center confidence
Audience: Producers, artists, and teams trying to improve the actual record rather than admire the metric.
Primary question
How stable, legible, and emotionally coherent is the tonal center of the record?
Program frame
Turn the benchmark into practical moves for writing, arrangement, production, and mix decisions.
Corpus slice
Tonal center accuracy and ambiguity across reference reads
Creator Guide
Where creators can look first.
Creator move 01
Tighten the melodic center if the hook is emotionally vague or the chorus never feels harmonically anchored.
Creator move 02
Use modal color intentionally. A Dorian or Mixolydian lean should be framed as identity, not as detection noise.
Creator move 03
Audit chord voicings and bass movement when the intended key is clear to the writer but muddy to the listener.
Method cues
Production decisions this benchmark informs.
Step 01
Each track is analyzed using MusicMind's chromagram-based key detection with Krumhansl-Kessler profiles.
Step 02
Confidence is derived from correlation between observed pitch-class energy and learned tonal templates.
Step 03
Ambiguity labels reflect how strongly the detected center dominates close competing tonal candidates.
Step 04
All analysis runs client-side in the browser with no server-side audio processing.
