Harmonic Ambiguity Rate by Album

Ambiguity rate counts chord events where the MIDI transcriber could not detect a clear third — a mix of real root+5th voicings, “The Standard” (root+5th+9th) shape, and distortion-masked triads. See Chord Vocabulary.

What Changed

Density

Densest album: Don’t Wait at 11.0 n/s — Sparsest album: Defenestrator at 2.8 n/s. That’s a 8.2 n/s spread across the catalog, a significant range that suggests real stylistic evolution.

Tempo

Fastest album: Don’t Wait at 208 BPM — Slowest album: Defenestrator at 155 BPM. A 53 BPM spread — enough to feel like a different energy level.

Harmonic Ambiguity Trend

Harmonic ambiguity rate trends upward over the catalog — from 58.0% (Albert Liberto — SoundCloud Instrumentals) to 52.2% (True Crime). More of the later chord events register as root+5th with no detectable third — consistent with a heavier, more distorted sound.

Outliers

These albums diverge significantly from the catalog average:

  • America — sparser than average (4.8 vs 6.9 n/s)
  • Anyone But Hindenburg — denser than average (9.1 vs 6.9 n/s)
  • Defenestrator — sparser than average (2.8 vs 6.9 n/s); slower than average (155 vs 195 BPM)
  • Defenestrator - bozo — sparser than average (4.9 vs 6.9 n/s); slower than average (176 vs 195 BPM)
  • Defenestrator — Recovered — sparser than average (4.0 vs 6.9 n/s); slower than average (168 vs 195 BPM)
  • Don’t Wait — denser than average (11.0 vs 6.9 n/s); faster than average (208 vs 195 BPM)
  • Flabby Wings — denser than average (8.9 vs 6.9 n/s)
  • Game Over — slower than average (182 vs 195 BPM)
  • Goodnight — faster than average (208 vs 195 BPM)
  • Party Rock — sparser than average (4.8 vs 6.9 n/s)
  • She Said — denser than average (10.0 vs 6.9 n/s)
  • Sticky Buns — sparser than average (3.4 vs 6.9 n/s); slower than average (179 vs 195 BPM)
  • The Why Because — denser than average (10.3 vs 6.9 n/s)
  • True Crime — denser than average (9.2 vs 6.9 n/s)

Footnotes

  1. “Harmonic ambiguity rate” measures the percentage of detected chord events where the MIDI transcriber could not resolve a clear third — closely correlated with the power chord idiom but not literally a count of intentional power chord voicings. See Chord Vocabulary for details.
