Formula card EX_064 — Ludwig, the Holy Blade

Game: Bloodborne · Composer: Nobuyoshi Suzuki · Purpose class: BOSS

Tier: RUNG-1 MEASURED · measured 2026-08-07T11:53:24+00:00 · source format mov,mp4,m4a,3gp,3g2,mj2 at 44100 Hz

Length 247.999 s across 16 sections; baseline 184.57 bpm; key A major.
Opens silence_then_hit; the hook lands at 3.17 s.
Arrangement runs up to 9 spectral lanes; melodic salience 0.4846 across 90 extracted notes.
Event grammar: 23 drops, 16 raises, 2 breaks, 26 tutti passages; silence budget 3.6%.
Dynamic range 15.52 dB, peak at 42% through the track.
Complexity steps 17 times across 190 bars, 6 of them at a section boundary.

Lanes are a spectral_band_proxy reading, not an instrument roster. Section 11.1 requires the lane method be declared. Bands are not instruments: two instruments in one octave read as one lane, and one instrument spanning two octaves reads as two. Entry/exit and simultaneity shapes are trustworthy; a roster is not claimed.
Bar arithmetic on this card uses 4 beats per bar at the baseline tempo. The onset period beside it is MEASURED; the signature is not.
A cadence census needs harmonic transcription and is a rung-2 dimension; the seam measurement is what rung 1 can honestly report about how it ends.
Windowed key agreement below ~0.7 is the modulation signal at rung 1; a pivot-chord map needs symbolic transcription (rung 2).
